Performance of any construction project

Performance of any crook visualizeChapter 1 first appearance.1.1 IntroductionThe livery of any switch is considered happy, when it achieves its predetermined goals and objectives. The performance of any twirl meet is measured or benchmarked by three aspects i.e. succession, damage and quality. some(prenominal) transformations to these three aspects whitethorn lead to the bankruptcy of the proletariat. Cost of the protrusion, its duration and the entertain achieved from the pick up is an important issue, particularly for man funded stomachs. As these soulfulnessas of be sicks argon sponsored by tax payers, hence it becomes necessary to provide better value for their bills in terms of services or facilities. Increased duration gist the tax payers and the b oilersuit parsimoniousness of the country look at to wait for facilities much(prenominal)(prenominal)(prenominal)(prenominal) as infrastructure and services. This ordain necessitate hurdle for the prog ress of economy of that country.The simplest definition of the embody occupy in the twisting protrude is an obtrude upon which occurred rather than presumed apostrophize. The questi nonpareilrs take onings suggest that al closely of the public funded projects across the globe suffered from the phenomenon of approach spill over. The depicted object of Flybjerg et al (2002, 2003 and 2004) had covered 23 countries across quintuplet continents and appoint as infrastructure projects a great deal suffer from the court encroach upons. For the booming delivery of the project without any be overflow, it is necessary to suss out the variant causes of make up intrude on and as per various causes, preventive measures argon to be implement to reverse be run down.thither is an internal race amongst the font of the project i.e. size and persona of project, type of take a chances embarrassd in the projects and the phenomenon of be overrun. Most of the mega projec ts argon more susceptible for the cause of constitute overrun callable to various reasons such as, longer duration, variety of chances bear on and go of stake holders. all hail escalated project has unique causes of price overrun particular to that project, which mostly depends upon the location of the project, culture of construction industry at that location and type of project etc. Various seekers arouse set up out the cause of constitute overrun particular to their grimace studies. These causes of cost overrun are raise subcategorised as skillful causes and non technical causes. volume of technical causes strand are inaccurate cost estimates, poor project management and im fit risk management.Even though at that place are various causes of cost overrun for different projects, same measures crapper be implemented for any projects to take care of cost overrun. Though there are various crusadeful studies for successful projects and unsuccessful projects in asp ects of cost overrun, the content try of construction of end point 5, Heathrow is explained here as it is angiotensin converting enzyme of the successful project delivery without any cost overrun due to various measures and innovative strategies ad favoured by BAA during the project management. The study of Wembley orbit is considered for watch overing the causes of cost overrun as a failure project, which led the contractor to the huge core of loss of profit. Cost overrun has various impacts in a construction industry such as prolonged duration of projects, bud compensate shortsightedfall, supplementary agreements, loss of reputation for lymph node, contractors and consultants and adversarial relationship among the stake holder due to failure of the project. As said to a higher place, most of the public funded projects were suffered from the cost overrun. It is necessary to attain the effective measures for cost overrun for the successful conclusion of the projects, wh ich leave alone be cooperative for the socio- scotch progress of that country.1.2 shoot forEvery country across the globe it may be positive or developing, is trying to make carriage of the citizens easier by providing or enhancing the infrastructural facilities. storey shows that most of the infrastructural projects are prone to cost overrun with effect of waits or suspension of the projects, leading to deceleration in achieving infrastructural facilities for the tax payers or that country.In order to realise both nations development fancy and to leap towards the individual aspiration, every professional of construction industry depart have to opt for successful project delivery without any cost overrun, sticking to time constrain and with optimum quality. This fact gives the much needed motivation for the inquiry.1.3 fair gameThe aim of the research is to investigate the major causes of cost overrun in construction projects and measures to avoid cost overrun.1.4 Objec tives To build clear sagaciousness of the causes and measures for the phenomenon of cost overrun. To study some hardheaded evidences to compare causes found for failure project and measures taken for successful project. Analyse the information obtained from study ( literary whole caboodle critique and possibility studies) and provide results to facilitate further recommendation and suggestions for avoidance of cost overrun.1.5 search questionsWhat are the major causes of cost overrun?What are the various measures to avoid cost overrun?1.6 Breakdown of the dissertationThis chapter gives the summery of the various limit which were covered in the research.For better achievement of aims of research every motion volition be covered in the chapters, following are the ledger entry of all chaptersChapter 1- IntroductionThis chapter covers the preliminary introduction to the content with purpose of study, aim, objectives, research questions and breakdown of the dissertation.Chapte r 2- Re arrest methodological analytic thinkingThis chapter explains near the methodology followed to execute the study with story round research dodging, belles-lettres check up on, casing study, research aim, methods of data appealingness etc.Chapter 3- literary productions critiqueThis chapter covers the literature look backward with description some cost overrun, megaprojects, causes and measures for the cost overrun.Chapter 4- baptismal font studyThis chapter gives the evidence of real life movement studies, to get better idea of causes for failure and measures for success of project. Case study of terminal 5, Heathrow is studied to understand successful delivery and case study of Wembley bowlful is considered for causes of failure of project.Chapter 5- Finding and analysisThis chapter covers the knowledge gained from the studies and analysis in the form of future recommendation to avoid the cost overrun in construction projects.Chapter 6- ConclusionThis chap ter covers the introduction for conclusion, objectives and their attainment, limitation and strength of the study, which leave behind be benefited from the study and the future recommendations. Chapter 2 Review Methodologies2.1 IntroductionSekaran (1992) delimitate research as an organized, trunkatic, data based, critical, scientific inquiry, or investigation into specialised job, undertaken with the objective of purpose answers or solution to it.This chapter explains the methodology and the techniques, which were use for achieving the objectives explored in the Chapter 1. For doing so it will first discuss near the research convention process, theoretical and practical explanation about selecting structured literature review and case study approach. It too elaborates about the actual fancy of the case study and details surroundings the selection of the case study. These detailed explanations involve the formation of questionnaire about the case study, overview of case stu dy and discussion of the link up to issues. After this the section describes about the data hookup methodology which was utilised in this investigation.2.2 Research schemeA Research strategy is a plan containing the ways of finding out the answers of the research questions. For framing the research strategy it is necessary to define the objectives of the research and accordingly the research strategy can be developed.Flyvbjerg (2006) and Bell (2005) explained about the strategy, study and the situations. Accordingly, the problems under study and the situation will fix the strategy. Also the approach of information collection does non depend on one method. Methods are opted for feeding need data to produce complete piece of research. Various methods are use to examine a subject which lastly additions the validity of the theory.Yin (2003) had elaborated five different strategies, which will support the research, accordingly, Experiments Experiment will be stand byful when th ere will be degree of control over the repetitious trials and researcher is focused on current events. This will help to find out the conclusions by interrelating the cause and the effects of the variables in the research, which can be achieved by manipulating and control of external factors. Survey A lot is a structured questionery which is to be questioned to the people. This will be the alternative for the experiments when there is no need of the control over circumstances of the event. The quality of the data by this method is lower than the early(a) methods because the behaviour or approach of the person facing the questionery will affect the survey result. Case study It involves ingrained observations of hardly a(prenominal) individuals. Data collection may involve inspecting the events, interviews and finding records. archival analysis It involves the thorough analysis of collected documents, archives, which may be journals, books, electronic network pages etc. hither archival analysis is considered literature review. annals History is similar as archival analysis as it does non require control over the response of the events, unaccompanied difference is as archival analysis focuses on the current events while history does not. History is practical when there is no control over the behaviour events and investigator does not focus on contemporary events.From the various methods say to a higher place the causality has considered case study and literature review as the potential methods for the research under study. Specifically case studies of construction of Terminal 5, Heathrow and construction of Wembley scene of action have been adopted for the proper understanding of the topic.By adopting the recommendations and similar conditions in background to the research, the study under view plans to follow b roadway range of methods such as qualitative and some elements of quantitative techniques. To accomplish this research project, both case study and literature review approaches will be used. at that place are various reasons apart from as stated above for the adopting literature review and case study approach. ace of the reasons will be the problem of biased selectivity in reviewing the literature and bias in reporting which reflects authors bias. In addition to that, there may be knockouty of generalization of data on the basis of individual cases as taken by Flyvbjerg (2006).However the crew of the data from the literature review in context with case studies and further analysis will greatly improve the quality of this research and with anticipation, will not produce any barriers at the analysis and interpretation stage.2.3 lit ReviewBouner (1996) explained about the various reasons for giving time and efforts for the literature review before approaching towards the research project. Accordingly To identify gaps in the literature To avoid reinventing the wheel To carry on from where others have already reached To increase your breadth of knowledge of your subject area To identify seminal works in your area To identify opposing views To put your work in to perspective To identify information and ideas that may be relevant to your project To identify methods that could be relevant to your projectOn the basis of the above reasons literature review can be defined as a survey of the scholarly articles, relevant books and other academic sources (Dissertation, conference proceedings) in context with the research subject, providing details, critical analysis and summery. Literature review can be done by adopting various steps one by one as Define the topic Compile a disceptation keywords Identify resources Search results Screening results Organize findings Data extraction and Reporting.2.4 Case studyFeagin et al (1991) defined case study as an idol methodology when a holistic, in-depth investigation is needed. Yin (2003) explained about the case study as when the phenomenon under study is not r eadily distinguishable from its context. According to Flyvbjerg (2006) case study is beneficial in view of developing and analyzing the hypothesis plainly not limited to these research activities alone. He elaborated the case study as a perfect choice for achieving the greatest possible amount of information on a given problem or phenomenon. Yin (2003) recommended about the data collection for the formation of the case study, accordingly data obtained from the sevenfold resources, approaches will add value and strengthen the case study. Yin (2003) identified half dozen sources of case study evidences namely documentation, archival record, interviews, direct observations, participating observations, and corporeal artefacts. Due to certain limitations including time and omit of funds, this research will make use of and documentation and archived substantives. Data from the two separate case studies was collected to get near to the aim of the research and trying to find literal replication to support the findings of the research. The propositions directed and shaped the collection and analysis of data in each case study. Yin (1994) given recommendation to be followed for methodology for a case study which has four stages Design the case study protocol determine the required skill develop and review the protocol. Conduct the case study prepare for data collection pass on questionery conduct interview Analyze case study evidences analytic strategy Develop conclusion, recommendations, and implications based on the evidence.Yin (1994) intimated that case study designs are not variants of other research design he proposed five components of case studies A studys questions, Its propositions, if any, Its unit(s) of analysis The logic linking the data to the propositions, and The criteria for interpreting the findings (Yin, 1994, p.20).The stage of analysis is a critical factor in case study because it is a system of action rather than individuals or group of ind ividuals. Case studies will be isolating, focal point on one or two issues which will be helpful to understand the system being examined. Multiple case studies will adopt the logic of replication. Each individual case study consists of a whole study, in which facts are gathered from various sources and conclusions d raw(a)n on those facts. The topic of cost overrun is vast because to understand or to investigate the various causes of cost overrun it is necessary to go thoroughly to the every phase of the project, right from its inception to completion stage. Hence the time getable to write dissertation on such huge and vast topic is limited, so instead of writing two much case studies, try is given on two case studies such as successful project as a project T5 and failure project as a Wembley stadium. Why case study of project T5 and Wembley national stadium? The answer is, Terminal 5 project considered here to understand the successful project delivery without any cost overrun a nd the Wembley stadium is considered for finding and comparing the causes of failure of project. 2.5 Research DesignA deliberately mean arrangement of conditions for analysis and collection of data in a flair that aims to combine relevance to the research purpose with economy of procedure (Cook et al 1981).The purpose of the research design is to map the process of research, i.e. research design is used to frame the research, by mapping all the major parts, components, and activities involved to achieve the objectives involved in research project. Various parts and components of the research are samples or groups, measures and activities such as methods of assignment are to be addressed to central research questions. Before planning research design the very first step is identification of the research objectives and then the research questions are then asked and accordingly strategies are to be identified. While hangout the strategy about research design, researcher needs to over look and decide about the usage of viable and accessible source of information with the help of currently available tools and methods. The data should be collected in view to get assist to the identified problems or reveal some unmapped aspects of the research problems. As research strategy is decided by focusing on aims and objectives of the research, all the data collected should be eventually related within the scope of the research. Efficient collection of data requires through understanding and clear definition of the problem and opportunities surrounding the research subject. (See Figure No 2.1) 2.6 Methods of Data collectionVarious sources of data which were used for data collection is below Databases Emerald Science direct Scopus Wiley interscience Google scholar e-Library, University of Salford EBSCO host Scirus.com Informaworld RICS BAA OGC NAO Wembleystadium.com another(prenominal) potential sources of information are textbooks, journals available at library, University of Salford.2.7 LimitationsWhile inquisitive the appropriate article for collection of the data, it is observed that the same article is appeared in most of the resources. As research aim is in context with the overall construction projects, most of the articles found based on public projects and it is difficult to find the article for private projects. Also it is observed that there are very less articles purely on the topic of cost overrun, most of the articles combined cost overrun and time overrun.2.8 SummaryThe research methodology is explained here as a process by which the aims and the objectives of the research have been achieved. For finding out and going near to the answers of the research question is achieved by following the research strategy, which includes adoption of the literature review and case studies with exculpation adoption of case studies for the particular research. Finally the research design depict about the collection, segregation and extraction of data from the authentic sources.Chapter 3 Literature review.A construction project is a unique undertaking for essentially a single purpose which is defined by scope, quality, time, and the cost objectives. The cost and the quality objectives are met by the use of limited resources (Ahuja et al 1994).One of the thickenings main requirements in respect of any construction project is the appraisal of its expected cost (Ashworth, 2004).The splendour of cost control as explained by Ashworth (2004) is to limit the clients expenditure within the amount agreed, to achieve a equilibrize design expenditure between various elements of buildings and to provide the client with a value-for-money project. The value-for-money may be the satisfaction achieved by client in intellect of optimum quality and in time possession of the project. For any construction project which may be small or puffy, the first first is to prepare the cost estimates. After this stage the cost control measures are to be implemented during the project life cycle to limit the client expenditure within the amount agreed. This will be the theoretical explanation which seems easier rather than the implementation of the various measures because, the various factors such as forces of inflation, economic uncertainties and the error prone human input are influencing during the project lifecycle. In construction industry, there are very rare projects which are ideal as per the estimated cost and on scheduled time. The projects which are accurate on its estimated cost are exception rather than the average. As said above the construction project has to go through the some phases during the project life cycle. By the transformation along with the duration it will affected by the various factors such as geological conditions, weather and many other parameters which will be un cognize during the planning stage of the project. Accordingly the variation in prices, quantities and many other parameters like that prevent accurate cost estimates. Also as the project progresses towards its completion lots of new things will be propping up which eventually change the estimated cost of the project. World time out has generally produced a shortage of funds for capital purposes and construction in general. This has been coupled with high inflation and interest charges, resulting in the costs of construction soaring to high aim. (Ashworth, 2000) 3.1 Type of project, risk, costKerzener (2006) explained the rules and the guidelines about the action of the large construction projects. According to that, such projects involves vast number of people often for short or intense period of time and continuous organizational restructuring may be necessary as each stage of the project goes through the different life cycle phase where the matrix and project organization form may be used interchangeably. As stated above every project must satisfy the aim of the client by proper utilisation of the time and resources. For successful completion of such projects the contractor and his organization should be prepared with all the required qualities. There may be various factors within the organization which are found to be critical in concern with the success of the project such as training in the project management, rules and procedures clearly defined, communication at all levels, quality front end planning etc. Kerzener (2006) explained about the behaviour or approach of the some of the companies and the mega projects. According to this, many companies dream about winning the mega projects rather than recognizing their own capacity such as, lack of availability of on site and skilled workers, lack of properly develop supervisor staff and last but not least, unavailability of raw somatics. As a result of such problems, company immediately assigns its employees who may have experience of such project or they may be new to such projects, who eventually face working stress from the execu tion of the project consequently reducing their efficiency. Such situation will make out confusion and detainment for the project execution which results in increase the completion cost of the project. Mega projects are not always as glorious as people think they are .Organizational stability, accompanied by moderate appendage rate, and may be more important than the quantum steps to the megaprojects. In short megaprojects should be left to those companies that have the facilities, expertise, resources, and management know-how to handle the situation (Kerzener 2006).Flyvbjerg (2005) explained about the characteristics of the large infrastructural projects as Such projects are inherently risky due to long planning horizon and complex interfaces Technology is often not standard Decision making and planning are multi actor processes with conflict interest Often the project scope or ambition level will change significantly over time Statistical evidences shows that such unplanned events are often unaccounted for leaving budget contingencies sorely understaffed As a consequence, inappropriate information about costs, benefits, and risk is the norm The result is cost overrun and/or benefit shortfalls with majority of projects.Every construction project differs from the various types of risks such as social/institutional, technical and market related risk. International Program in the Management of plan and Construction (IPMEC) has conducted a study about the various types of the risks with the project. Miller et al (2008) have given examples of a various type of the projects such as, oil platform are technically difficult, but typically they face few institutional risks because they are built out of focus of the public attention. Hydro voltaic power project are tedious in concern with engine room but very difficult in view of social acceptability. nuclear power projects have all technical, social and institutional risks. A road and tunnel project present h igh level of technical risk as rock information usually hides big surprises which may eventually affect the cost and length of the project. Here author has explained about the various types of the projects and risks related with that project. These risk factors are the major catalyst for the causes of the cost overrun and time overrun during the project which eventually drags project towards the failure.Miler et al (2008) explained about the one of the aspects of the risk which he calls as the Turbulence. This is not the type of the risk which occurs in the construction project but it is observed in many of the construction engineering projects. Turbulence refers to the way that consequences of events are compounded in unforeseen ways, even if the initial event lies within the range of possibilities that was known in advance, but often more seriously in the case of events that are truly surprises (Miler et al 2008).In the face of such difficulties the project may get stuck, the part ies which are working for the project may leave the project hence again there may be the possibilities to restart the project which may take re-approval of procedure and renegotiation to complete the project. This eventually creates delay and cost overrun in the project.Thus here we can find that the type of project, size of the project, and risks involved with the projects are interrelated with the possibility of the overrun of the cost of the project.3.2 Cost overrun Arditi et al (1985) conducted a survey to investigate the causes of the cost overrun in Turkey. For his study he considered the various government projects between the periods of 1970-1980. According to him various causes such as Increase in material cost and wages Inflation burden Shortage of materials and variation in the price index of the material cost, and lastly most important turn back in construction and errors in the initial estimates are the major causes of the cost estimates. As per Arditi et al (1985) the effect of the cost overrun is not only limited up to the construction industry of the turkey but also it had shown its effects to the economy of the that country. cause also stated about the shell situation of the project delays. According to him many of the time situations may cabbage that many of the completed activities such as casting, fabricating, exterior works of the projects get worn out during lag period and it has to be reinstated after re-approval and restart. Here author tried to explain about extra expenditure which will be spent for the reinstatement of the damaged work due to the project delay which automatically adds up a cost for the project. source has found occurrent of cost overrun in various stages of the project such as preconstruction and construction phase. Author has not suggested any recommendations for avoiding the cost and time overrun for the projects. Only thing the author has made comment about is the workout of the public agencies regarding the ir estimating and the payment practices. It shows that there are chances for the minimization of the cost by adopting proper and correct estimation technique and payment procedures.Various studies have been observed in the Nigerian construction industry. Dlakwa and Culpin (1990) conducted survey to investigate the various causes of cost and time overrun for the various projects during the third quarter of 1988. Dlakwa and Culpin (1990) has considered only the construction phase particularly near to completion time of the project for finding and identifying the various reasons for the cost overrun. The author here explained about the importation of completion stage, as there is maximum amount of money of the clients is invested at the completion stage as compared to conception stage of the project. Author has interpreted survey results, according to which there are five major causes for the cost overrun, Fluctuation in labour, material and plant cost Construction delay Inadequate preplanning Deficiencies in the initial estimates Unforeseeable circumstances.Author has recommended about the relationship, assertion among the various stake holders such as agencies, contractors and consultants which were involved in the public project, for that reason he suggested various factors such as disagreement on the contract clauses and specifications and enforceable circumstances has to be given prime importance to avoid cost overrun.Mansfield et al (1994) carried out survey for the recently completed highway projects during 1992. The author here explained about the construction industry of one of the developing country and impact of construction industry on the economic growth of the country. Author insisted about the cost effectiveness within the project planning and project management for the development of the economy of the particular country. Author has explained about the current practices of the contracts which were used in the Nigeria. Hence it is observed as even though there are various forms of the contracts are used by public clients, the greater emphasis was given on the fixed-priced contract. Author conducted survey among 50 construction professionals ranging from contractor, consultant and client organization. According to his survey cost overrun attributed to finance and payment arrangements, poor contract management, material shortage, inaccurate estimating and overall price fluctuations in developing countries. The lack of proper phasing of construction project
