Self reflection evaluation of standardized patient exams Essay

Self reflection evaluation of standardized patient exams - Essay Example Yes, I am pleased with the way I communicated during the interview. This is because I was able to maintain an eye contact and give the time for the interviewee to answer the questions. This is very critical in retrieving the information. However, if it happens again, I would start with simple questions in order to gain the trust of interviewee. In the video, two things that I did well are active listening and displaying appropriate empathy. These are skills that I learned during training. They were important in enabling me to get in-depth information from the interviewee. After watching video, I realize that if I was given another opportunity, I would train more and ask more questions with the SP. This is through reading more books and watching videos of effective interviews. This would enable me to learn more skills from other professionals. My main goal is to gain experience in the nursing career. I also intend to learn the bigger picture of the FNP role. This would be significant in enabling me to understand ways of serving the patients

A Story Review from the 16th Century Essay CHARACTERS: THE KING THE EARL OF CORNWALL SIR HUGH LACY, Earl of Lincoln. ROWLAND LACY, otherwise disguised as HANS, nephew of Sir Hugh Lacy ASKEW, another nephew of Sir Hugh Lacy SIR ROGER OATELEY, Lord Mayor of London. Master HAMMON, Master WARNER and Master SCOTT: Citizens of London. SIMON EYRE, the Shoemaker. ROGER, commonly called Hodge, a Journeyman of Simon Eyre FIRK, another journeyman of Simon Eyre RALPH, another Journeyman of Simon Eyre LOVELL, a courtier. DODGER, servant to The Earl of Lincoln A DUTCH SKIPPER. A BOY. ROSE, daughter of Sir Roger, the love interest of Rowland Lacy SYBIL, the maid of Rose MARGERY, wife of Simon Eyre JANE, wife of Ralph SETTING: London and Old Ford, England, as it happened in the 16th century PLOT DEVELOPMENT: With the different sub-plots evolving in The Shoemaker’s Holiday, the central plot is about the desperate love between Rowland Lacy and Rose Oateley.     And they defied the odds:   Rowland did not obey his uncle the Earl of Lincoln to go to war and Rose rejected the arranged marriage with Master Hammon, who is of wealth and nobility from London.     Sir Roger thought Rowland went to war.   Instead, Rowland apparently went to study shoemaking in Germany. He eventually went back to London; disguised himself as Hans a Dutch shoemaker and worked for Simon Eyre, a shoe shop owner and a real shoemaker.   Rowland and Rose went through the maze of re-discovering each other; plotting ways and means to be secretly married; and surmounting the ire and the vehemence of their respectively opposing families.   With the backdrop of the rise of Simon Eyre from being a simple man to achieving success and wealth, such paved the way for eventual happy conclusion of the fulfillment of the love of Rowland and Rose. SYMBOLISM: The Shoemaker’s Holiday generally illustrated basic features of the paradoxes in life:   unrequited love vis-à  -vis the determination to achieve its fulfillment; difference in social standing vis-à  -vis sustaining integrity of an individual inspite of any variance; applying duplicity and deceit to achieve a noble objective; how success can come and test humanness. In analyzing the various plots of The Shoemaker’s Holiday, Conover (1969) said:   â€Å"Achievement, promotion, advancement of all kinds are pictured in the play. For several of the characters in the play Simon Eyre is instrumental to success. The shoemakers, too, rise up the social scale – and Eyre tells them that opportunity is open to all.   Simon Eyre is, of course, the central example of the opportunities for success.   As he rises from shoemaker to Alderman, rich man, Sheriff, and Lord Mayor†¦Ã¢â‚¬ ¦.[though the] main plot has to do with the love of young Lacy and the mayors daughter, most critics consider the Eyre action to be central in the play.† With such positive characteristic of the play, it is interesting to note that the author Thomas Dekker conversely led a nearly unknown life of deprivation.   He was constantly in debt and was in and out of prison for his inability to meet his obligations. As reviewed by The Harvard Classics:   â€Å"The play is full of an atmosphere of pleasant mirth, varied with characteristic touches of pathos; and it contains in the figure of Simon Eyre a creation of marked individuality and hilarious humor. It is striking that the most high-spirited picture of London life in the time of Elizabeth should come from the pen of the author who seems to have been more hardly treated by fortune than any of his contemporaries.†Ã‚   (Eliot, 1909) Indeed the tenor of the story is honest and realistic.   All the struggles that came by have been met with acceptance and resolve:   to surpass and emerge as victorious.   The need to bridge differences and misunderstanding were sought.   The overall intention of the theme of the story is allowing the truth of love and dignity of individuality its own due course. In a review of the Early Modern Theatre of the Theatre Studies Department of Duke University, it was noted that:   â€Å"Fantasy and reality blur, giving the plot a surreal quality that would be appealing as a holiday play: wishes come true and hopes are fulfilled.   However, realities do not completely disappear in this drama, ‘they keep returning, unexpectedly, to interrupt, trouble, and question any easy reading that would entertain by way of ignorance or innocence the real cost of social mobility and fluidity that is necessary in a class-ridden society’†¦..Thomas Dekker wrote a drama for the citizens of London, and incorporated social issues and ideas that citizens would be interested in.† (Duke University, undated) HOW THE STORY REFLECTED THE ASPECTS OF THE 16TH CENTURY† It has been described that:   â€Å"Literary development in the earlier part of the 16th century was weakened by the diversion of intellectual energies to the polemics of the religious struggle †¦Ã¢â‚¬ ¦. The English part in the European movement known as humanism also belongs to this time. Humanism encouraged greater care in the study of the literature of classical antiquity and reformed education in such a way as to make literary expression of paramount importance for the cultured person. Literary style, in part modeled on that of the ancients, soon became a self-conscious preoccupation of English poets and prose writers. Thus, the richness and metaphorical profusion of style at the end of the century indirectly owed much to the educational force of this movement. The most immediate effect of humanism lay, however, in the dissemination of the cultivated, clear, and sensible attitude of its classically educated adherents, who rejected medieval theological misteaching and superstition.   The school of thought known as humanism, promoted the revival of Greek and Roman artistic and philosophical models that celebrated the worth of the individual.† (MSN Encarta, 2007). Because of a re-invention of the literary style at that time, the common pursuits for greatness and distinctiveness surfaced amongst the writers of that time.   â€Å"The Elizabethan Era is the period associated with the reign of Queen Elizabeth I (1558–1603) and is often considered to be a golden age in English history. It was the height of the English Renaissance, and saw the flowering of English literature and poetry. This was also the time during which Elizabethan theatre flourished and William Shakespeare, among others, composed plays that broke away from Englands past style of plays and theatre.† (Elizabethan Era, http://www.answers.com/topic/elizabethan-era) With such overall characteristics that prevailed during the 16th century, the aura of prosperity and practical domination and excellence in every aspect of life is exemplified in The Shoemaker’s Holiday.  Ã‚  Ã‚   â€Å"London in the 16th century underwent a transformation. Its population grew 400% during the 1500s, swelling to nearly 200,000 people in the city proper and outlying region by the time an immigrant from Stratford came to town. A rising merchant middle class carved out a productive livelihood, and the economy boomed.†Ã‚   (Shakespeare Resource Center, 2008) The Shoemaker’s Holiday indeed encapsulated everything that is real and positive abounding in that period where new leaps in perspective about life and identity emerged.

The Shoemaker’s Holiday:   A Synopsis www.theatredatabase.com/17th_century/shoemakers_holiday.html An Abstract: Rowland Lacy, the nephew of Sir Hugh Lacy, the Earl of Lincoln, and Rose, the daughter of Sir Roger Oateley, the Lord Mayor of London are in love, but their families do not approve.     To separate them, Sir Roger sends Rose to the country, in Old Ford.   Sir Hugh sends Rowland to war in France.   Rowland disobeyed Sir Hugh and instead went to Germany and study shoemaking.   Rowland returns to London.   Disguised as a Dutch shoemaker, Rowland went to Simon Eyre, a shoe shop owner, for work and introduced himself as Hans.   Rowland and Simon sealed a very good friendship because when a cargo shipment at a very good price came up for sale, Rowland gave his war gift money to Simon to purchase the cargo.   This made Simon very wealthy.   Sir Hugh learned that Rowland is not in the war in France.   Meantime, Sir Roger was already arranging the marriage of Rose to Master Hammon, rich nobleman from London.   Rose vehemently refuses to marry Master Hammon. Meanwhile, Simon becomes the Sheriff of London and Sir Roger threw a party celebration for Simon in his house in Old Ford.   Simon and his shoemakers were invited.   During the dancing and merrymaking, Rose suspects that Hans is Rowland – inspite of Rowland talking in gibberish English to safeguard his disguise.   After the celebration, Rose and Sybil went to London.   Sybil asked Hans to take the shoe size of Rose and make a new pair of shoes. While Rowland and Rose are struggling for their love in the story, Simon has a journeyman named Ralph who was also sent to war.   Ralph is married to Jane.   Jane thought Ralph was killed in the war.   So she left off and no one knows of her whereabouts. Jane met Master Hammon – not knowing that a failed marriage arrangement transpired between Master Hammon and Rose.   So, Master Hammon was besotted to Jane and asked her to marry him.   Believing that Ralph is dead, Jane agreed and they were set to marry in St. Faith Church in London.   However, Jane wants the last gift of Ralph, a pair of shoes specially made for her, be duplicated to a brand new one to become her wedding shoes.   Master Hammon obliged and went to the shoe shop of Simon Eyre and ordered the duplication.   Meanwhile, Ralph returned to London because he was hurt in the war and was discharged.   Ralph returned to work with Simon and sadly learned that his wife left him for nowhere.    On that day that the shoe duplication for Jane was ordered, Ralph saw it and was therefore sure that it will lead her to his wife Jane.   Going back to the time when Rowland was taking the shoe size of Rose, Rowland had the chance to quietly and secretly instruct Rose to go to the house of Simon Eyre.   At this time, Simon became the new Mayor of London.   And as such, Simon could marry Rose and Rowland.   Eventually, Rose did so and they finally got married.   Sybil revealed the treachery of Rose and Rowland to Sir Roger and Sir Hugh.   But Sir Roger and Sir Hugh was told that the wedding will take place in the St. Faith Church. Whilst Sir Roger and Sir Hugh were on their way to St. Faith Church to take Rose from Rowland (as Hans), Ralph and with his shoemaker friends are already waiting in the church to take Jane from Master Hammon.  Ã‚   When Sir Roger and Sir Hugh arrived, it was a moment that Jane lovingly recognized her husband Ralph and apologized to Master Hammon for the cancellation of the wedding as she is still in love with Ralph.   Sir Roger and Sir Hugh were disgusted that they were seemingly duped because it was a different wedding that was suppose to transpire that moment.    Sir Hugh and Sir Roger nevertheless learned that Rowland and Rose are already married.   Sir Hugh and Sir Roger appealed to the King to nullify the marriage.   But King who has been enamoured with the antics and humanness of Simon as he treats his shoemaker workers fairly; he remains humble inspite of his wealth – worked out a solution to the enmity between the parents of Rowland and Rose and them.   The King divorced Rowland and Rose and re-married them and declared Rowland a knight just so the issue of differences in social standing come to an end.

Cost Overrun in Construction Projects

Cost Overrun in Construction Projects Aim The aim of the dissertation is to identify and explore the various causes of cost overrun associated with construction projects. Objectives Identifying the main causes of the cost overrun in the construction projects through literature review. To identify the various measures of cost overrun in construction projects. To examine the affects of the cost overrun by analysing the case of a construction industry. Analysing the information from the literature review and case studies to provide further recommendation and suggestions to overcome the cost overrun effect. Research Methodology To achieve the above aims discussed above it is very important to do extensive research by studying books, journals, articles on internet. Qualitative method is the research method that will be the main research method used incorporating Observations Questionnaire Case studies Present dissertation the author has used two main research methods questionnaire survey, case studies. The author has prepared questionnaire with 18 questions and forwarded to 10 companies. The questionnaire survey provided valuable data that can analyse, useful for outcome of the research. The author has studied different case studies from India to identify various causes for failure of the project. Analysis on the case studies gives the idea of various measures to overcome cost overrun. Introduction Constructions are full of risks and include those that may relate to cost overrun, external commercial factors, design, construction and operation. In any construction projects the three primary factors that is time, cost and quality will be likely to subject to risk and uncertainty. This cost overrun can be minimised by the realistic estimation which can be anticipated from the experience and foresight. Managing project costs accurately and responsively is a challenging task for the design team, construction manager, builders and consultant. Effective cost management is dependent on following a consistent methodology, utilizing appropriate standards, concentrating efforts for maximum effectiveness and utilizing all the tools available. The major problem that arises in construction projects is that projects often overrun their cost estimate. This risk of the overrun of cost estimate occurs even with the projects where carefully constructed bottom up cost estimates completed to a very detailed level. In every construction projects the main problem where cost of the entire project is not getting most likely, is because of the usual way of constructing a project estimate at completion is that adding the estimates for all work breakdown structure components (WBS). By conducting a cost risk analysis provides a more accurate and realistic estimates of project costs. Chapter-2 2. Literature Review 2.1 Definition: The process of project of an infrastructure project when planned is the sponsoring department prepares estimates of time and costs or funds needed to complete the project. The expected date of the completion is also announced. But there will arise some different between the actual date of completion from the expected date. We define â€Å"time overrun† as the time difference between the initially planned i.e. expected dates of completion. Therefore, for each project we can define percentage time overrun as the ratio of time overrun and the implementation phase of the project. The implementation of the project is defined as the duration in which project is completed, i.e. the time between the date of approval of the project and the expected date of completion of the project. Similarly cost overrun is defined as the difference between the actual cost and the expected cost of the project. The actual cost is the cost that can be calculated only at the end of the project and the es timated cost is the estimated when the project is planned. The percentage of cost overrun is defined as the ratio of the cost overrun and the initially anticipated cost of the project (Ram Singh, 2009). According to Lewis and Atherly 1996 a delay may have the direct cost implications in terms of an extended construction period. In other words delay leads to the cost overrun and the extended time will have extra expenses or loses by both parties of the project. When a delay can increase cost and reduce profits then organizations will have more considerations on bottom line (Lewis and Atherly 1996) 2.2 Causes of Construction Cost Overrun The survey conducted by Iyer and Jha (2005), on the factors affecting the cost performance of Indian construction projects, including the extent of adverse climatic and economic conditions; unfavorable project specific attributes; top management support; monitoring; feedback, coordination, conflict and knowledge of the project participants; and reluctance to make timely decisions. Of these, coordination among project participants was found to be the most significant of all factors, having a maximum positive influence on the cost performance. Semple et al. (1994), examined causes of claims, delays and cost overrun on twenty four projects in western Canada. The study identified the following as critical factors that lead to cost overruns are (1) contract variations and extras, (2) disputes, (3) soil and site conditions, and (4) delays. The author stressed the need by the industry practitioners (clients, contractors, professionals) to pay maximum attention to the critical factors in order to minimize cost overrun risks. Chan et al. (1997), examined the principal and common causes of delays which leads to cost overrun in Hong Kong construction projects. The study identified the following factors (1) Poor site management and supervision, (2) unforeseen ground conditions, (3) low speed of decision making by project teams, (4) client-initiated variations and (5)necessary variations of work, as major cause of delay. Flybjerg et.al. (2003), pointed out to cost estimates as highly, systematically and significantly misleading. According to Flybjerg et al. (2004), the causes for the cost overrun in the construction projects is as follows (1) The length of the project in the implementation phase, (2) the size of the project and (3) the type of project ownership. According investigation carried by Assaf et al. (1995), on causes of delay in high rise building construction projects in Saudi Arabia, the most important causes are found to be as follows (1) Inadequate designs, (2) slow work progress on site, (3) late payment for completed works and (5) design changes by owners. Here from the above investigation it is proven that all these factors are caused by the lapses in human input factor. N R Mansfield et al. (1994), investigated and examined the causes of delay and cost overrun in Nigerian projects. The investigation identified the following factors that are attributed to the overrun are finance and payments arrangements, poor or in experience contracting management, material shortages or excess of the materials, inaccurate estimating, and overall price fluctuations The analysis according to Ram Singh (2009), has shown that there has been significant decline in the time and cost since from early 1980s in India. The investigation shows that major causes for the delays and cost overruns observed in India are deficient project planning process, use of inappropriate procurement contracts and faulty contract management. In regards to project type, the bigger projects are much more vulnerable to cost overruns. Ram Singh also stated that several kinds of organisational-cum-institutional failure also affect greatly to time and cost overruns. The studies conducted by Elinwa et al. (2001) on the relative contribution of human personnel parties to the projects time overruns and cost overruns in Nigerian Construction industry states that the contribution of clients, contractors and others were 62%, 32% and 6%. The study stated that on the government or private sector projects the delays were at 89% with irrespective of project size. The study also identified the important factors of cost overrun and time overrun are mode of financing, payment delays for the completed works, improper planning and project time and cost underestimation. Kaming et al. (1997), examined factors influencing constriction delays (time overrun) and cost escalations, in Indonesian cities. They identified project cost underestimation and project complexity as the main causes of project delays and cost overruns. Chan and KumaraSwamy had conducted a survey on the factors causing the delays in Hong Kong construction projects and had classified them into two groups: (1) the role of the parties in the local construction industry (whether client, consultant or contractor) and (2) the type of projects. The result shows that five major causes for the delays and cost overrun were poor site management and supervision, unforeseen ground condition, low speed of decision making involving all project teams, client initiated variations and necessary variation of work. Cost underestimation is the one of the main factors for the cost overrun in construction projects. According to the Flyvbjerg, (2003), the cost underestimation exists across 2 nations and 5 continents and it is global phenomenon. The explanation for the cost underestimation is in four types. Technical Psychological Economic Political Technical Explanation: Most studies in infrastructure projects that compare actual cost at the completion of the project and estimated cost at the initial contract explain as Forecasting Error in technical terms such as imperfect techniques, inadequate data, honest mistakes, inherent problems in predicting the future, lack of experience on the part of forecast, etc,. [Flyvbjerg, 2003]. Psychological Explanation: Psychological explanations attempts to explain biases in forecasts by a bias in the mental makeup of the project promoters and forecasters. Politicians may have a Monument Complex engineers like build things, and local transportation officials sometimes have the mentality of empire builders in building roads, railways and bridges. The most common psychological explanation is probably â€Å"appraisal optimism†. According to this explanation, promoters and forecasters are held to be overly optimistic about the project outcomes in the appraisal phase, when the projects are planned and decided. [coated in Flyvbjerg, 2003]. Political Explanation: Political explanations construe cost underestimation in terms of interests and power (Flyvbjerg, 1998). According to Flyvbjerg, 2003, one of the key questions for political explanations is whether forecasts are intentionally biased to serve the interests of project promoters in getting projects started. Cost estimation cannot be explained by the errors and seems to best explained by strategic misrepresentation i.e., lying. These questions of lying are notoriously hard to answer. For legal, economic, moral and other reasons, if promoters and forecasters have intentionally fabricated a deceptive cost estimate for a project to get it started, they are unlikely to tell the researchers and others that this is the case. Economical Explanation: Economic explanations say that cost underestimation in terms of economic rationality. Flyvbjerg, 2003, in his journal stated that there exist two types of economic explanation. One explains in terms of economic self-interest, the other in terms of public interest. In case of the economic self -interest, during the process of the project it creates the work for the engineers and construction firms, and many stakeholders who are directly or indirectly attached with the project make money. These stakeholders in directly involved in would influence the forecasting process of the project, which in turn influence the outcomes the ways that make it more likely that the project will be built. Stakeholders would likely increase in their revenues and profit by having the cost underestimation and benefits over estimation which would be economically rational for such type of stake holders. In case of the second term public interest, project promoters and forecasters may intensively underestimate cost in order to provide public officials with an incentive to cut costs and thereby to save the publics money. According to this type of explanation, the more cost estimate is the incentive of the wasteful contracts to spend more of the tax payers money. Hence the both types of the economic explanation account well for the systematic underestimation of the costs. Several researchers on the subject of construction cost overruns have come out with significant findings that factors that leads to time overrun (construction delays), will eventually leads to cost overrun. From the above literature it is also found that the size of the construction project is also one of the main reasons which influence the cost overrun. The researchers stated that the main factor leading to delays have been always studied alongside those leading to cost overrun. 2.3 Cost overrun in India Background Cost overrun is becoming common in infrastructure projects. Through the various analyses it is found that the time delay and the cost overrun are the main reasons for the poor project performance. Morris and Hough found 63% of 1778 different types of projects funded by the World Bank between 1974 and 1988, experienced significant cost overrun. kamrul Ahsan and Indra Gunawan, (2008), in studies conducted on the time and cost performances in Asian countries had found out only few projects i.e. 13% are completed within time and budgeted cost. In contrast more projects are time delay and cost over run on an average amount of over spending U.S. $73million, i.e. 22% average planned cost. The case study conducted by the Standish group (2004) for IT projects the has found that the average cost overrun was 43%, 71% of projects were over budget, over time and under scope and the total waste was estimated at U.S. $5 billion per year in U.S.A alone. In-accuracy in cost estimates is also one of t he main factors for the cost overrun in the construction projects. According Flyvbjerg (2002), the under estimation of costs in construction were almost 9 out 10 projects. For randomly selected projects, the likelihood of actual costs being larger than estimated cost is 86%. The likelihood of the actual costs for the construction projects is being lower than or equal to estimated cost is 14%. The actual cost of the projects on average is 28% higher than the estimated cost. The best example for the above case is Suez Canal was constructed at costs three times of the estimated cost with 1,900 percent (Flyvbjerg et al, 2002). The Kakkad hydro -electric projct could be commissioned in time in 1986 itself, 8 years after its construction started. Accounting for general price inflation during this period , thecapital cost of this project by 1986 would be atmost only rs 39.66 crores, savings as much as Rs. 113.86 crores, almost enough to construct 3 more similar plant, or to add to the syst em capacity y another 140 MW at the nominal cost of Kakkad project in Kerala (Kannan and pillai 2001). The ultimate motive in undertaking the project is to make profit. These profits may be measured in different ways and the most familiar profit is money. The goals of the others in making the project may be to make work, to improve living standards, in produce of the products to the others who require it or in scarce, to obtain votes for the political carrier and many others. The ultimate result should be the positive outcome during the construction of the project or in the life of the project. Every project has to undergo several stages starting from the planning of the project, approval, awarding the project to the actual construction and so on. The project life cycle has been divided into three phases they are development phase, construction phase, and operation and maintenance phase. For every project during the development phase the project authority will approves the time and funds needed for the completion of the project. Then after the approval of the project the construction phase will start with the signing of a contract between the sponsoring department and the contractor. Generally the contractor of the project will be selected through the tender or bidding process. For some projects contractor will be for only procurement process. During the construction phase it is very important for the timely completion of the project, so there should be the active cooperation between the sponsoring authority, the contractor and other departments. The project success i.e. wh ether the project can be delivered on time and on cost depends on how well all the activities of the projects, departments of the projects and individuals concerned are coordinated. The failures among the contractor activities will cause delays in the project and cost overruns. For the ease of exposition, it is helpful to divide the set of possible causes in the following subgroups (Ram Sing, 2009). 2.3.1. Technical and Natural Factors: It is a complex problem for the estimation of the time and cost for an infrastructure projects, though the techniques for the estimation have been sophisticated there are many imperfect estimations. The contractors and the authorities of the project will better understand about the materials requirement and the necessary changes in the project as the work on the project starts. For example, during the construction phase of the road project, an unexpectedly poor quality of soil may make the changes in the design and quality of the bitumen, from what was initially planned. Because such changes the project may require extra time as well as funds. But in some cases the sudden changes may turn in favor of the project and the parties may find the excessive funds and time. Similarly natural factors like floods and so on also impact the cost and time and as well as destroy the project assets. The natural factors also make favorable conditions in saving the construction time and cost. However , one would expect the effects of the technical and natural factors to be random without any bias. Also form the above discussions the time delay and cost overrun is expected to come down over the years. Therefore if the decline in the time delay and cost overrun is expected to be statistically significant, we attribute the decline to the technical and natural constraints. Time and cost overrun. Hence, the Design changes, unforeseen geological and weather condition during the construction phase are the major causes of the cost overrun. (Ram Singh, 2009) 2.3.2 The Contractual Failures. As explained earlier the contractor enters the project mostly through bidding in implementation or construction phase by signing the contract with the sponsoring department. Thus for a project to be successful, mostly depends on the implementation of the activities by contractor and the joint and timely efforts of the sponsoring authority and the contractor(s). The actual initial construction or procurement contract is signed between the employer and the contractor is on a particular date. The contract agreement specifies the activities that are performed and delivery of the goods at the project execution by the contractor. In general, contract known as â€Å"complete-contingent-contracts which can ensure that the project is completed on time and within budget. These types of contracts are assumed to give the each and every detail of the activities that are performed by the contractor in each possible case during the construction phase. But in real case scenario, however, this is di fficult to explain the every work which unfolds in construction phase during the initial phase of the contract. Moreover it does not explain the complete every relevant aspect of the project activities. The bounded relationship of the parties along with the technological constraints makes the contract very difficult in specifying the every aspect of the project till last detail, this is because of the nature of different states require different modifications in the assets to be built. This happens commonly for the contracts of the infrastructure projects because of its complex nature of the activities. Therefore the procurement contracts of the infrastructure projects will be incomplete nature. The need for the future works arises once when the contractors starts the work. For example, on a railway project it may be necessary to have more of manned-crossings or railway-over-bridges than were planned initially. These unplanned additional works requires more funds and also in some ca ses it takes more time. Therefore, from the above discussion the contract incompleteness is also a cause of the cost overrun in some cases. This contractual incompleteness increases with the increase in the project size. Bigger the project size the complexity also increases. As the complexity of the project increases it is very difficult to provide the each every detail in the initial contract. However the initial contract should be kept with less incomplete. A proper planning for the technical, materials and the activities aspects of the project can enable the parties involved in the project to make the detail initial contract properly and once the proper detailed initial contract is made the contractor may have the scope to make some allowance for the future works by keeping the initial contract with less incomplete. In contrast, the poor planning may lead to the bad estimation of the time and cost and so will be the initial contract. The process of project planning in India is in famous for its ad-hoc and lackadaisical approach. The detailed project reports and feasibility are prepared for the formality purpose and hence they are sloppy. This leads to the incomplete initial contract for the infrastructure projects. Thus this leads to sever problems for the complex projects, because, a lackadaisical planning will produces only sketchy estimates of time and cost. So, in these cases the initial contracts for the complex projects will inevitably omit many more detailed works of the project, which leads in cost overrun in the construction phase of the project. Neither the contractors nor the officials find these contracts are lack of details. From this the major cause which is leading to cost overrun in India is because of the contractual failures caused by the poor contracting processes and inferior project planning (Ram Singh, 2009). The example for the faulty planning techniques and construction made the cost and time overrun of the project in the Kerala state hydro project in kakkad where the leakage in the tunnel had costs the project extra 15 Lacks to repair the damage.( Kannan and pillai 2001). 2.3.3 Organizational failures: As discussed from the above literature, for the successful completion of the infrastructure i.e. timely and efficient execution the project should have active participation of the all parties involved in the projects and as well as among various ministries. However, the government sector projects are inherently weak in the desired efforts from the people involved in the projects. There will be conflicts at each and every stage of the project with the individual and the social objectives. The wages and rewards given by the government for the working organization are not as effective from the view point as a motivation. Therefore, the government infrastructure projects have to face many sources of failures within the organization. These projects mostly in need of the several other organizations joint effort. In India different departments are responsible for different projects. For example, project implementation of power lines, water lines, sewer lines and environmental clearances and other such activities are performed by the different departments. Execution of the activities is highly dependent on the timely and joint efforts of the department. However the interdependence of efforts is that it will be easy for one department to pass the blame on others. So the infrastructure projects particularly India is vulnerable to these inter-organizational failures. In the project implementation stage as explained earlier several departments were involved in performing there concerned role. After all, the activities like land acquisition, shifting of utilities, etc., are performed by the state government. This says that if the project is span across more than one state, the project has deal with particular department in each state. Therefore the project which is spanning more than one state will have more chances to inter-organizational failures. If these projects are statistically causes the delay in time and cost overrun, then the project which are spanning across mult iple states should experience the cost overrun and time delay. Most construction projects in government sector are Roads, Rail ways and urban development sector. The projects should need permission from the central and state government for the environmental clearance. When compared other sectors, these projects require more active cooperation of the several departments such as land acquisition, shifting of power lines, water lines, sewer lines etc. Hence the projects in these sectors are having more chances of the organizational failure. Thus projects in road, rail ways and urban development sectors will exhibits more time delays and cost overrun (Ram Singh, 2009). Kannan and Pillai 2001, in their studies on the cost and time overrun in Kerala Projects suggested that main cause of the cost overrun is due to the human resource management and labours strike. According to the Auti, et,al. (2008), there has been several changes which should be made to the quality and standards, personal interests, low transparency and corruption . This also suggests that changes should be made in government policy and the way public sector projects are carried out. 2.3.4 Economic Factors: In India the projects are located in some states and the economy of the state also impacts the cost overrun of the projects. That is the states having the good transportation facilities, power and telecommunication infrastructure to easily execute the project. This shows that project with more economic factors like good infrastructure will face less cost overrun and time delays and vice versa. The income level of the state will also affect the project cost and time (Ram Singh, 2009). 2.3.5 Inflation: The inflation is defined as the rate of increase in the price level of the materials than they are in an economy (Adamson, 1996). Thus because of the inflation the materials cost will be increased than they during the initial contract, thus increases the estimated cost of the project. The affect inflation may cause the loss in profit to the contractor and project overrun cost to the project sponsor by the nature of process and the return of the work undertaken during the construction process. For example the kakkad(Kerala, India), hydro electric plant which has the time overrun 13 years as in 1999, when it was finally commissioned, the cost escalation of this project was 725 percent over the above estimates i.e. 8 times more than the actual cost the author says the cost escalation of this project is because of the price inflation(Kannan and pillai 2001 ). 2.3.6 Quality of the materials The low quality materials cause higher construction costs than expected because of lack of standards in the materials. This results in the loss of materials and poor management system (Thungphanich, 1997). 2.3.7. Shortage in materials Shortages in basic materials like sand, cement, stones, iron and brick causes major delay in the construction. The non availability of the machinery at the right of the construction process is also major cause for the delay in the construction. The following table shows that the various sectors which went the time overrun and cost overrun in India. These are the delays and the cost overrun during the years April 1992- September 208 S.

Measures for the cost overrun 2.4.1. Cost Estimates: For any project the most important aspect in order to meet the funds of the project is the cost estimation. Small misleading in the cost estimation will lead to the project cost overrun or under run. Kerzer (2006) have explained about the factors which are affecting the process of the estimation and which results in the faulty estimation for the construction. The factors such as Misinterpretation of statement of the works, Omission or improperly defined scope, poorly defined or overly optimistic schedule, inaccurate work break down structure, applying improper skill levels to tasks, failure to account of risks, failure to understand or account for cost escalation and inflation, failure to use correct estimating technique. The important aspect to be considered is that many of the above factors which are affecting the cost estimation of the construction cannot be found until and unless the cost control system is implemented within the project. Kerzer (2006) also explained various types of measures in estimating and their accuracy in the cost overrun, they are as follows. (1) Order -of-magnitude estimates: There is no necessary of any engineering data for these types of estimates. Hence they are prepared without any engineering data and mostly they are based on the past experience. The accuracy Cost Overrun in Construction Projects Cost Overrun in Construction Projects Aim The aim of the dissertation is to identify and explore the various causes of cost overrun associated with construction projects. Objectives Identifying the main causes of the cost overrun in the construction projects through literature review. To identify the various measures of cost overrun in construction projects. To examine the affects of the cost overrun by analysing the case of a construction industry. Analysing the information from the literature review and case studies to provide further recommendation and suggestions to overcome the cost overrun effect. Research Methodology To achieve the above aims discussed above it is very important to do extensive research by studying books, journals, articles on internet. Qualitative method is the research method that will be the main research method used incorporating Observations Questionnaire Case studies Present dissertation the author has used two main research methods questionnaire survey, case studies. The author has prepared questionnaire with 18 questions and forwarded to 10 companies. The questionnaire survey provided valuable data that can analyse, useful for outcome of the research. The author has studied different case studies from India to identify various causes for failure of the project. Analysis on the case studies gives the idea of various measures to overcome cost overrun. Introduction Constructions are full of risks and include those that may relate to cost overrun, external commercial factors, design, construction and operation. In any construction projects the three primary factors that is time, cost and quality will be likely to subject to risk and uncertainty. This cost overrun can be minimised by the realistic estimation which can be anticipated from the experience and foresight. Managing project costs accurately and responsively is a challenging task for the design team, construction manager, builders and consultant. Effective cost management is dependent on following a consistent methodology, utilizing appropriate standards, concentrating efforts for maximum effectiveness and utilizing all the tools available. The major problem that arises in construction projects is that projects often overrun their cost estimate. This risk of the overrun of cost estimate occurs even with the projects where carefully constructed bottom up cost estimates completed to a very detailed level. In every construction projects the main problem where cost of the entire project is not getting most likely, is because of the usual way of constructing a project estimate at completion is that adding the estimates for all work breakdown structure components (WBS). By conducting a cost risk analysis provides a more accurate and realistic estimates of project costs. Chapter-2 2. Literature Review 2.1 Definition: The process of project of an infrastructure project when planned is the sponsoring department prepares estimates of time and costs or funds needed to complete the project. The expected date of the completion is also announced. But there will arise some different between the actual date of completion from the expected date. We define â€Å"time overrun† as the time difference between the initially planned i.e. expected dates of completion. Therefore, for each project we can define percentage time overrun as the ratio of time overrun and the implementation phase of the project. The implementation of the project is defined as the duration in which project is completed, i.e. the time between the date of approval of the project and the expected date of completion of the project. Similarly cost overrun is defined as the difference between the actual cost and the expected cost of the project. The actual cost is the cost that can be calculated only at the end of the project and the es timated cost is the estimated when the project is planned. The percentage of cost overrun is defined as the ratio of the cost overrun and the initially anticipated cost of the project (Ram Singh, 2009). According to Lewis and Atherly 1996 a delay may have the direct cost implications in terms of an extended construction period. In other words delay leads to the cost overrun and the extended time will have extra expenses or loses by both parties of the project. When a delay can increase cost and reduce profits then organizations will have more considerations on bottom line (Lewis and Atherly 1996) 2.2 Causes of Construction Cost Overrun The survey conducted by Iyer and Jha (2005), on the factors affecting the cost performance of Indian construction projects, including the extent of adverse climatic and economic conditions; unfavorable project specific attributes; top management support; monitoring; feedback, coordination, conflict and knowledge of the project participants; and reluctance to make timely decisions. Of these, coordination among project participants was found to be the most significant of all factors, having a maximum positive influence on the cost performance. Semple et al. (1994), examined causes of claims, delays and cost overrun on twenty four projects in western Canada. The study identified the following as critical factors that lead to cost overruns are (1) contract variations and extras, (2) disputes, (3) soil and site conditions, and (4) delays. The author stressed the need by the industry practitioners (clients, contractors, professionals) to pay maximum attention to the critical factors in order to minimize cost overrun risks. Chan et al. (1997), examined the principal and common causes of delays which leads to cost overrun in Hong Kong construction projects. The study identified the following factors (1) Poor site management and supervision, (2) unforeseen ground conditions, (3) low speed of decision making by project teams, (4) client-initiated variations and (5)necessary variations of work, as major cause of delay. Flybjerg et.al. (2003), pointed out to cost estimates as highly, systematically and significantly misleading. According to Flybjerg et al. (2004), the causes for the cost overrun in the construction projects is as follows (1) The length of the project in the implementation phase, (2) the size of the project and (3) the type of project ownership. According investigation carried by Assaf et al. (1995), on causes of delay in high rise building construction projects in Saudi Arabia, the most important causes are found to be as follows (1) Inadequate designs, (2) slow work progress on site, (3) late payment for completed works and (5) design changes by owners. Here from the above investigation it is proven that all these factors are caused by the lapses in human input factor. N R Mansfield et al. (1994), investigated and examined the causes of delay and cost overrun in Nigerian projects. The investigation identified the following factors that are attributed to the overrun are finance and payments arrangements, poor or in experience contracting management, material shortages or excess of the materials, inaccurate estimating, and overall price fluctuations The analysis according to Ram Singh (2009), has shown that there has been significant decline in the time and cost since from early 1980s in India. The investigation shows that major causes for the delays and cost overruns observed in India are deficient project planning process, use of inappropriate procurement contracts and faulty contract management. In regards to project type, the bigger projects are much more vulnerable to cost overruns. Ram Singh also stated that several kinds of organisational-cum-institutional failure also affect greatly to time and cost overruns. The studies conducted by Elinwa et al. (2001) on the relative contribution of human personnel parties to the projects time overruns and cost overruns in Nigerian Construction industry states that the contribution of clients, contractors and others were 62%, 32% and 6%. The study stated that on the government or private sector projects the delays were at 89% with irrespective of project size. The study also identified the important factors of cost overrun and time overrun are mode of financing, payment delays for the completed works, improper planning and project time and cost underestimation. Kaming et al. (1997), examined factors influencing constriction delays (time overrun) and cost escalations, in Indonesian cities. They identified project cost underestimation and project complexity as the main causes of project delays and cost overruns. Chan and KumaraSwamy had conducted a survey on the factors causing the delays in Hong Kong construction projects and had classified them into two groups: (1) the role of the parties in the local construction industry (whether client, consultant or contractor) and (2) the type of projects. The result shows that five major causes for the delays and cost overrun were poor site management and supervision, unforeseen ground condition, low speed of decision making involving all project teams, client initiated variations and necessary variation of work. Cost underestimation is the one of the main factors for the cost overrun in construction projects. According to the Flyvbjerg, (2003), the cost underestimation exists across 2 nations and 5 continents and it is global phenomenon. The explanation for the cost underestimation is in four types. Technical Psychological Economic Political Technical Explanation: Most studies in infrastructure projects that compare actual cost at the completion of the project and estimated cost at the initial contract explain as Forecasting Error in technical terms such as imperfect techniques, inadequate data, honest mistakes, inherent problems in predicting the future, lack of experience on the part of forecast, etc,. [Flyvbjerg, 2003]. Psychological Explanation: Psychological explanations attempts to explain biases in forecasts by a bias in the mental makeup of the project promoters and forecasters. Politicians may have a Monument Complex engineers like build things, and local transportation officials sometimes have the mentality of empire builders in building roads, railways and bridges. The most common psychological explanation is probably â€Å"appraisal optimism†. According to this explanation, promoters and forecasters are held to be overly optimistic about the project outcomes in the appraisal phase, when the projects are planned and decided. [coated in Flyvbjerg, 2003]. Political Explanation: Political explanations construe cost underestimation in terms of interests and power (Flyvbjerg, 1998). According to Flyvbjerg, 2003, one of the key questions for political explanations is whether forecasts are intentionally biased to serve the interests of project promoters in getting projects started. Cost estimation cannot be explained by the errors and seems to best explained by strategic misrepresentation i.e., lying. These questions of lying are notoriously hard to answer. For legal, economic, moral and other reasons, if promoters and forecasters have intentionally fabricated a deceptive cost estimate for a project to get it started, they are unlikely to tell the researchers and others that this is the case. Economical Explanation: Economic explanations say that cost underestimation in terms of economic rationality. Flyvbjerg, 2003, in his journal stated that there exist two types of economic explanation. One explains in terms of economic self-interest, the other in terms of public interest. In case of the economic self -interest, during the process of the project it creates the work for the engineers and construction firms, and many stakeholders who are directly or indirectly attached with the project make money. These stakeholders in directly involved in would influence the forecasting process of the project, which in turn influence the outcomes the ways that make it more likely that the project will be built. Stakeholders would likely increase in their revenues and profit by having the cost underestimation and benefits over estimation which would be economically rational for such type of stake holders. In case of the second term public interest, project promoters and forecasters may intensively underestimate cost in order to provide public officials with an incentive to cut costs and thereby to save the publics money. According to this type of explanation, the more cost estimate is the incentive of the wasteful contracts to spend more of the tax payers money. Hence the both types of the economic explanation account well for the systematic underestimation of the costs. Several researchers on the subject of construction cost overruns have come out with significant findings that factors that leads to time overrun (construction delays), will eventually leads to cost overrun. From the above literature it is also found that the size of the construction project is also one of the main reasons which influence the cost overrun. The researchers stated that the main factor leading to delays have been always studied alongside those leading to cost overrun. 2.3 Cost overrun in India Background Cost overrun is becoming common in infrastructure projects. Through the various analyses it is found that the time delay and the cost overrun are the main reasons for the poor project performance. Morris and Hough found 63% of 1778 different types of projects funded by the World Bank between 1974 and 1988, experienced significant cost overrun. kamrul Ahsan and Indra Gunawan, (2008), in studies conducted on the time and cost performances in Asian countries had found out only few projects i.e. 13% are completed within time and budgeted cost. In contrast more projects are time delay and cost over run on an average amount of over spending U.S. $73million, i.e. 22% average planned cost. The case study conducted by the Standish group (2004) for IT projects the has found that the average cost overrun was 43%, 71% of projects were over budget, over time and under scope and the total waste was estimated at U.S. $5 billion per year in U.S.A alone. In-accuracy in cost estimates is also one of t he main factors for the cost overrun in the construction projects. According Flyvbjerg (2002), the under estimation of costs in construction were almost 9 out 10 projects. For randomly selected projects, the likelihood of actual costs being larger than estimated cost is 86%. The likelihood of the actual costs for the construction projects is being lower than or equal to estimated cost is 14%. The actual cost of the projects on average is 28% higher than the estimated cost. The best example for the above case is Suez Canal was constructed at costs three times of the estimated cost with 1,900 percent (Flyvbjerg et al, 2002). The Kakkad hydro -electric projct could be commissioned in time in 1986 itself, 8 years after its construction started. Accounting for general price inflation during this period , thecapital cost of this project by 1986 would be atmost only rs 39.66 crores, savings as much as Rs. 113.86 crores, almost enough to construct 3 more similar plant, or to add to the syst em capacity y another 140 MW at the nominal cost of Kakkad project in Kerala (Kannan and pillai 2001). The ultimate motive in undertaking the project is to make profit. These profits may be measured in different ways and the most familiar profit is money. The goals of the others in making the project may be to make work, to improve living standards, in produce of the products to the others who require it or in scarce, to obtain votes for the political carrier and many others. The ultimate result should be the positive outcome during the construction of the project or in the life of the project. Every project has to undergo several stages starting from the planning of the project, approval, awarding the project to the actual construction and so on. The project life cycle has been divided into three phases they are development phase, construction phase, and operation and maintenance phase. For every project during the development phase the project authority will approves the time and funds needed for the completion of the project. Then after the approval of the project the construction phase will start with the signing of a contract between the sponsoring department and the contractor. Generally the contractor of the project will be selected through the tender or bidding process. For some projects contractor will be for only procurement process. During the construction phase it is very important for the timely completion of the project, so there should be the active cooperation between the sponsoring authority, the contractor and other departments. The project success i.e. wh ether the project can be delivered on time and on cost depends on how well all the activities of the projects, departments of the projects and individuals concerned are coordinated. The failures among the contractor activities will cause delays in the project and cost overruns. For the ease of exposition, it is helpful to divide the set of possible causes in the following subgroups (Ram Sing, 2009). 2.3.1. Technical and Natural Factors: It is a complex problem for the estimation of the time and cost for an infrastructure projects, though the techniques for the estimation have been sophisticated there are many imperfect estimations. The contractors and the authorities of the project will better understand about the materials requirement and the necessary changes in the project as the work on the project starts. For example, during the construction phase of the road project, an unexpectedly poor quality of soil may make the changes in the design and quality of the bitumen, from what was initially planned. Because such changes the project may require extra time as well as funds. But in some cases the sudden changes may turn in favor of the project and the parties may find the excessive funds and time. Similarly natural factors like floods and so on also impact the cost and time and as well as destroy the project assets. The natural factors also make favorable conditions in saving the construction time and cost. However , one would expect the effects of the technical and natural factors to be random without any bias. Also form the above discussions the time delay and cost overrun is expected to come down over the years. Therefore if the decline in the time delay and cost overrun is expected to be statistically significant, we attribute the decline to the technical and natural constraints. Time and cost overrun. Hence, the Design changes, unforeseen geological and weather condition during the construction phase are the major causes of the cost overrun. (Ram Singh, 2009) 2.3.2 The Contractual Failures. As explained earlier the contractor enters the project mostly through bidding in implementation or construction phase by signing the contract with the sponsoring department. Thus for a project to be successful, mostly depends on the implementation of the activities by contractor and the joint and timely efforts of the sponsoring authority and the contractor(s). The actual initial construction or procurement contract is signed between the employer and the contractor is on a particular date. The contract agreement specifies the activities that are performed and delivery of the goods at the project execution by the contractor. In general, contract known as â€Å"complete-contingent-contracts which can ensure that the project is completed on time and within budget. These types of contracts are assumed to give the each and every detail of the activities that are performed by the contractor in each possible case during the construction phase. But in real case scenario, however, this is di fficult to explain the every work which unfolds in construction phase during the initial phase of the contract. Moreover it does not explain the complete every relevant aspect of the project activities. The bounded relationship of the parties along with the technological constraints makes the contract very difficult in specifying the every aspect of the project till last detail, this is because of the nature of different states require different modifications in the assets to be built. This happens commonly for the contracts of the infrastructure projects because of its complex nature of the activities. Therefore the procurement contracts of the infrastructure projects will be incomplete nature. The need for the future works arises once when the contractors starts the work. For example, on a railway project it may be necessary to have more of manned-crossings or railway-over-bridges than were planned initially. These unplanned additional works requires more funds and also in some ca ses it takes more time. Therefore, from the above discussion the contract incompleteness is also a cause of the cost overrun in some cases. This contractual incompleteness increases with the increase in the project size. Bigger the project size the complexity also increases. As the complexity of the project increases it is very difficult to provide the each every detail in the initial contract. However the initial contract should be kept with less incomplete. A proper planning for the technical, materials and the activities aspects of the project can enable the parties involved in the project to make the detail initial contract properly and once the proper detailed initial contract is made the contractor may have the scope to make some allowance for the future works by keeping the initial contract with less incomplete. In contrast, the poor planning may lead to the bad estimation of the time and cost and so will be the initial contract. The process of project planning in India is in famous for its ad-hoc and lackadaisical approach. The detailed project reports and feasibility are prepared for the formality purpose and hence they are sloppy. This leads to the incomplete initial contract for the infrastructure projects. Thus this leads to sever problems for the complex projects, because, a lackadaisical planning will produces only sketchy estimates of time and cost. So, in these cases the initial contracts for the complex projects will inevitably omit many more detailed works of the project, which leads in cost overrun in the construction phase of the project. Neither the contractors nor the officials find these contracts are lack of details. From this the major cause which is leading to cost overrun in India is because of the contractual failures caused by the poor contracting processes and inferior project planning (Ram Singh, 2009). The example for the faulty planning techniques and construction made the cost and time overrun of the project in the Kerala state hydro project in kakkad where the leakage in the tunnel had costs the project extra 15 Lacks to repair the damage.( Kannan and pillai 2001). 2.3.3 Organizational failures: As discussed from the above literature, for the successful completion of the infrastructure i.e. timely and efficient execution the project should have active participation of the all parties involved in the projects and as well as among various ministries. However, the government sector projects are inherently weak in the desired efforts from the people involved in the projects. There will be conflicts at each and every stage of the project with the individual and the social objectives. The wages and rewards given by the government for the working organization are not as effective from the view point as a motivation. Therefore, the government infrastructure projects have to face many sources of failures within the organization. These projects mostly in need of the several other organizations joint effort. In India different departments are responsible for different projects. For example, project implementation of power lines, water lines, sewer lines and environmental clearances and other such activities are performed by the different departments. Execution of the activities is highly dependent on the timely and joint efforts of the department. However the interdependence of efforts is that it will be easy for one department to pass the blame on others. So the infrastructure projects particularly India is vulnerable to these inter-organizational failures. In the project implementation stage as explained earlier several departments were involved in performing there concerned role. After all, the activities like land acquisition, shifting of utilities, etc., are performed by the state government. This says that if the project is span across more than one state, the project has deal with particular department in each state. Therefore the project which is spanning more than one state will have more chances to inter-organizational failures. If these projects are statistically causes the delay in time and cost overrun, then the project which are spanning across mult iple states should experience the cost overrun and time delay. Most construction projects in government sector are Roads, Rail ways and urban development sector. The projects should need permission from the central and state government for the environmental clearance. When compared other sectors, these projects require more active cooperation of the several departments such as land acquisition, shifting of power lines, water lines, sewer lines etc. Hence the projects in these sectors are having more chances of the organizational failure. Thus projects in road, rail ways and urban development sectors will exhibits more time delays and cost overrun (Ram Singh, 2009). Kannan and Pillai 2001, in their studies on the cost and time overrun in Kerala Projects suggested that main cause of the cost overrun is due to the human resource management and labours strike. According to the Auti, et,al. (2008), there has been several changes which should be made to the quality and standards, personal interests, low transparency and corruption . This also suggests that changes should be made in government policy and the way public sector projects are carried out. 2.3.4 Economic Factors: In India the projects are located in some states and the economy of the state also impacts the cost overrun of the projects. That is the states having the good transportation facilities, power and telecommunication infrastructure to easily execute the project. This shows that project with more economic factors like good infrastructure will face less cost overrun and time delays and vice versa. The income level of the state will also affect the project cost and time (Ram Singh, 2009). 2.3.5 Inflation: The inflation is defined as the rate of increase in the price level of the materials than they are in an economy (Adamson, 1996). Thus because of the inflation the materials cost will be increased than they during the initial contract, thus increases the estimated cost of the project. The affect inflation may cause the loss in profit to the contractor and project overrun cost to the project sponsor by the nature of process and the return of the work undertaken during the construction process. For example the kakkad(Kerala, India), hydro electric plant which has the time overrun 13 years as in 1999, when it was finally commissioned, the cost escalation of this project was 725 percent over the above estimates i.e. 8 times more than the actual cost the author says the cost escalation of this project is because of the price inflation(Kannan and pillai 2001 ). 2.3.6 Quality of the materials The low quality materials cause higher construction costs than expected because of lack of standards in the materials. This results in the loss of materials and poor management system (Thungphanich, 1997). 2.3.7. Shortage in materials Shortages in basic materials like sand, cement, stones, iron and brick causes major delay in the construction. The non availability of the machinery at the right of the construction process is also major cause for the delay in the construction. The following table shows that the various sectors which went the time overrun and cost overrun in India. These are the delays and the cost overrun during the years April 1992- September 208 S.

Measures for the cost overrun 2.4.1. Cost Estimates: For any project the most important aspect in order to meet the funds of the project is the cost estimation. Small misleading in the cost estimation will lead to the project cost overrun or under run. Kerzer (2006) have explained about the factors which are affecting the process of the estimation and which results in the faulty estimation for the construction. The factors such as Misinterpretation of statement of the works, Omission or improperly defined scope, poorly defined or overly optimistic schedule, inaccurate work break down structure, applying improper skill levels to tasks, failure to account of risks, failure to understand or account for cost escalation and inflation, failure to use correct estimating technique. The important aspect to be considered is that many of the above factors which are affecting the cost estimation of the construction cannot be found until and unless the cost control system is implemented within the project. Kerzer (2006) also explained various types of measures in estimating and their accuracy in the cost overrun, they are as follows. (1) Order -of-magnitude estimates: There is no necessary of any engineering data for these types of estimates. Hence they are prepared without any engineering data and mostly they are based on the past experience. The accuracy

Adventures of Huckleberry Finn Race Relations  Ã‚  Ã‚  Ã‚   Humans are fascinated with real life situations, tagged in with fictional story line.   Mark Twain’s novel, The Adventures of Huckleberry Finn, describes real life situations, in a fictional story line perfectly.   Twain put the real life happenings of slavery, in a fun and fictional story.   The novel is mainly about the racial relations between each human.   Classes of society, loyalty/friendship, and rebellion shows how the novel evolves into a main theme of Race Relations.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Throughout the history of the world, people have been placed into categories based on their wealth, and all of the worldly possessions that we have.   These classes of society can really make people talk, and act differently towards some people.   In The Adventures of Huckleberry Finn, the novel shows these classes really well.   In the beginning of the novel, we see a little bit of the black class, and how they were treated.   â€Å"Miss. Watson’s big nigger, named Jim, was setting in the kitchen door, we could see him pretty clear† (14).   Jim, Miss. Watson’s run away slave in the story, is part of the black class.   We see the sub ordinance that blacks were placed in America, because blacks were not allowed to be in the house, because they were uneducated, and had to be working in the fields.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another example of the classes we put each other into is when Huck, the main character, and Jim were heading south.   Jim and Huck are sitting on the banks of the Mississippi River, and Jim says â€Å"I owns myself en I’s wuth eight hund’d dollars.† (54).   This shows the reader that blacks are so low, that the white people place prices on the blacks.   As uneducated as the blacks are, they believe they are worth so much money, because that is all they hear from their owners.   By doing such a thing to another human being, that degrades our country, and the black citizens themselves.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   At the end, we see how these classes can effect one person, due to his social status.   Like before, people say things to other people, to make themselves feel better, and they do not care what it does to the person they are talking about, because of their class in society.   One example of this is when â€Å"They cussed Jim considerably, though, and give him a cuff or two upside the head† (271).

Automatic Railway Level Crossing

AUTOMATED UNMANNED RAILWAY LEVEL CROSSING Abstract: In the rapidly flourishing country like ours, accidents in the unmanned level crossings are increasing day by day. No fruitful steps have been taken so far in these areas. The objective of our project is to provide an automatic railway gate at a level-crossing replacing the gates operated by the gatekeeper. It deals with two things. Firstly, it deals with the reduction of time for which the gate is being kept closed. And secondly, it provides safety to the road users by reducing the accidents.By employing the automatic railway gate control at the level crossing the arrival of the train is detected by the sensors placed near to the gate and transmits the information to the gate controller via wired or wireless. Hence, the time for which it is closed is less compared to the manually operated gates. The operation is automatic i. e. , error due to manual operation is prevented. By employing the automatic railway gate control at the leve l crossing the arrival of train is detected by the sensor placed on either side of the gate at about 3km from the level crossing.Hence, the time for which it is closed is less compared to the manually operated gates and also reduces the human labour. This type of gates can be employed in an unmanned level crossing where the chances of accidents are higher and reliable operation is required. Since, the operation is automatic error due to manual operation will be prevented. Once the arrival of the train is sensed, the sensed signal is sent to the microcontroller via, wired or wireless transmission and it checks for possible presence of vehicle between the gates.Subsequently, buzzer indication and light signals on either side are provided to the road users indicating the closure of gates. Once, no vehicle is sensed in between the gate the motor is activated and the gates are closed. But, for the worst case if any obstacle is sensed it is indicated to the train driver by signals (RED) p laced at about 1km, so as to bring it to halt well before the level crossing. When no obstacle is sensed GREEN light is indicated, and the train is to free to move. The departure of the train is detected by sensors placed at about 1km from the ate. The signal about the departure is sent to the microcontroller, which in turn operates the motor in reverse way and opens the gate. Thus, the time for which the gate is closed is less compared to the manually operated gates. Also reliability is high as it is not subjected to manual errors. Components : IR sensors or Vibration sensors, Microcontroller, L293D(driver IC), Stepper motor, Wireless Transmitter and Receiver, power supply. HARDWARE IMPLEMENTATION Micro Controller Totally 40-pin DIP package manufactured withCMOS Technology. L293D (motor driver IC) Racially L293D 16DIP /ULN 2003 IC is used to drive the stepper motor. STEPPER MOTOR This is used to open and close the gates automatically when it is rotated clock wise or anticlockwise d irection. Stepper motor requires 500m amps current, so use the L293D drivers to drive the stepper motor. SOFTWARE IMPLEMENTATION Keil By 1. B. BHARATH KUMAR REDDY – 113004045 2. P SAMBASIVA RAO – 113004161 3.

A Study of Factors Contributing to the Lack of Success and Participation of African American in Males in Advance Placement Classes

Abstract The purpose of this research brief is to offer a brief review of those factors that contribute to the academic achievement gap between African American males. A sample of 25 8th grade, African American, male students from Dent Middle School will be identifyied as participates for the research. Although there has been research written about the achievement gap between African American and their counterparts, the literature is limited regarding strategies tailored specifically to address the achievement gap between African American males.Participant’s data will be collected in relation to sex, race, age group, and attending school. Subjects will responded to an unobtrusive open-ended survey instrument. A survey consisting of 10 qualitative questions and will be used to developed for analysis. Introduction Studies have found that the level of the success of African American male students in advanced educational program is lower rates than nonblack peers (Few, 2004).Succe ss in early exposure to advance classes has shown that it ultimately impacts students’ pre college experiences, such as career choice, level of success, and the nature of participation extracurricular activities (Williams, 2011). Very few black males take advanced classes, which are more in line with college entrance requirements (Few, 2004). Instead, they stick to classes that meet basic high school graduation requirements (Few, 2004). Poverty is another barrier that blocks African American male from participation in the AP program.Most schools require a fee for taking an exam in each subject area (Williams, 2011). AP courses are not as accessible for minorities as for White students because many low-income schools (often primarily populated by minority students) do not offer any AP classes (Watts Silvernail, 2010). With most African American families living well below the nation poverty rate paying addition school fees is unrealistic (Cross, 2006). Further, the lack of expo sure to participating in advance placement class is also an issue that arises with African American males (Watts Silvernail, 2010).Influenced for many years by widespread opinion that they have substandard academic abilities, African American male students in many instances do not consider enrolling in the AP program (Williams, 2011). Consequently, when African American males are not being identified as being academically high achieving and they receive tremendous peer pressure not to achieve, it is no surprise that few African American young males are in honors or advanced placement courses (Cross, 2006).Despite these data, research is still necessary to understand why African American male student demonstrate lack of success and participation in advance courses. Purpose of the Study The purpose of this study is to examine the possible factors that contribute to the lack success and participation of African American males in advance placement classes by asking the following questio ns: 1. Are African American males encouraged to participate in advance placement classes? . What types of support in being offered to enhance participation for African American Males? 3. What influences are hindering participation in advance placement for African American males? Researchers have attempted to clarify the factors the contribute to the lack of success and participation of African American in males in advance placement classes, most of the discussion focuses on fundamentals such as poverty, discrimination, and availability.While there has been much written on the African American in males in advance placement classes, there are questions and problems that are fully or partially disclosed in the works of known scholars. Although there have been significant gains in the educational endeavors of African American students, the 1990s saw a reduction in the progress made with a significant widening of the achievement gap between African American and Caucasian students(Few, 20 04). According to the Education Trust, (2003), the black-white gaps are about 10 points wider than they were more than a decade ago .In addition to gaps in performance on achievement tests, gaps are found in grades, course selection, advanced placement (AP) course participation and test taking, high school graduation, and dropout rates (Legler, 2004). Theodore Cross was dedicated to the conscientious investigation of the status and prospects for African American males in higher education. In the journal article published in The Journal of Blacks in Higher Education Cross addresses educational limitation for African American males in regards to advance placement.While his research did reveal and address the fundamentals of the lack of participation in advance classes for African American males the article lacked objectivity. The focus of the article was centered on the racial scoring gap of advance placement and examined the significance of the interracial disparities between African American male. While is this a key component Jenel Few author of â€Å"The Odds are Against them: The Black Male Education Debacle† takes a stand on the lack of preparation is the leading factor that hinders African American males from partaking in advance classes.She discusses the teacher’s lack of preparation to education children from different social standing and educational standing as well. African American males tend to be underrepresented in advanced and honors courses and more likely to be placed in special education programs and suspended or expelled from school (Few, 2004). The article describes a singularity known as the stereotype threat, which impacts the way teachers view students and the way students view themselves.Stereotype threat influenced teachers’ low-achievement expectations for poor and minority students (Few, 2004). Watts Silvernail, (2010) An Examination of the Barriers and Supports to African-American Enrollment in Honors and Advance d Placement Courses doctoral dissertation examined the impact of teacher effectiveness on the learning of different types of students, from low to high achievers, illustrated the importance of quality teachers. In her studies she found that teacher’s quality has a â€Å"huge effect on how well students fare in school† (abstract).Silvernail discusses that there are many externally and internally generated factors that can influence African American male students' academic decisions to participate in AP classes. External factors include inaccessibility, socioeconomic status, and systemic barriers. Internal factors include cultural identity conflicts, learning style differences, and social isolation (abstract). Silvernail research determined that educational programs that promote equal access to higher education for traditionally underserved populations do exist among African American male.Her qualitative approach was used with the intention of using authentic voices Afri can American student voices to look for commonalities and differences between those students who choose the rigorous advanced track and those who do not (Silvernail, 2010). Method In this research study, The Factors Contributing to the Lack of Success and Participation of African American in Males in Advance Placement Classes will be examined. A qualitative method was chosen because it will offer a more purposeful sampling.The strength of qualitative research is its ability to provide complex textual descriptions of how people experience a given research issue (Robert, 1999). The main purpose of choosing qualitative method is the advantage of qualitative research is to provide a richer deeper understanding of a problem or question being observed. Qualitative methods are also effective in identifying intangible factors, such as social norms, socioeconomic status, gender roles, ethnicity (Robert, 1999). Each participant personified three characteristics: Black male, a student, and a v olunteer.Participants The participants of this study will include 40 African American male students in the grade to 8th grade at Dent Middle School in Columbia South Carolina who have reported not being successful or participating in advance placement classes. I chose Dent Middle School because of it diversity with students and teachers. In order to conduct a survey with students a paternal consent form was required do to the participants being under the age of 18 years of age. Survey Instrument Participants in this study will complete an survey that consists of 25 questions. see Appendix A) The survey was developed to collect data that will be used to analyze the reasoning behind the lack of success of African American males in advance placement classes.
