Abstract: The occurrence of time and cost overrun has become quite significant in a majority of construction projects in India, which is negatively affecting the GDP and potential development of nation. As per the statistics of project cost and duration in March 2012, 179 projects out of 555 projects of worth 150 Crore INR have been facing cost and time overrun and others are at the very high risk, with the total construction cost overrun of 1.23 Lakh Crore INR. (Times, 2013) The time and cost overrun of the construction projects results in overextension of the time and finance of the client w

However, the effect on project costs and time overrun of variation order has yet to be identified. This study evaluates the impact of variation orders on the cost and time off in the Sulaimani governorate.

Cost overruns are frequent in the construction industry. They become greater the more the construction project is delayed. In developing countries, this situation is recurring and constitutes a significant financial problem. In a time-overrun context, our objective is to find a method that can enable us to reduce the delay while minimizing the subsequent cost overruns. We thus developed a mathematical model named CCOMTOC (construction cost optimisation model in time-overrun context). The model was tested and results reveal that the reduction of cost overruns is effective. We showed that in a t

Construction project cost overrun is a common problem in the construction industry. The cost of construction projects is thought to have increased by approximately 33% on average. Several types of research on construction project cost overrun have been conducted and these generally rely on historical data. However, whilst each project has its own project characteristics and cost trend, real-time project cost data are more reliable to forecast its own cost trend. This paper proposes a real-time hidden Markov chain (HMM) model to predict cost overrun risk based on project-owned cost performance

<strong>Abstract:</strong> The present research aims to analyze the causes of delays and cost overruns in construction projects and to identify the methods to minimize delays and cost overruns. In the present era of rising need for infrastructure and growing competitiveness, construction projects must be completed on time and without cost overrun. Most construction projects are complex and filled with challenges, unexpected hindrances, and frequently emerging issues, leading to time and cost overruns. This research identified several government construction projects that suffered from delays a

The formidable need for building projects places greater pressure on stakeholders to deliver these projects on time, within the budget, and with high quality. However, many building projects have experienced extensive cost overruns despite extensive research on their causes and mitigation measures. Thus, the effectiveness of mitigation measures is questionable. This study examines the status of cost overrun in building construction projects and develops a structural equation model to establish the relationships between causes of cost overrun and mitigation measures, using higher education buil

Cost overrun is often a challenge in the construction industry due to its complex nature and inefficient project management. Despite extensive research, cost overruns persist in construction. Hence, to minimise these challenges, factors attributing to the cost overrun need to be identified. A country-based assessment is needed since these factors vary from nation to nation. Research conducted almost two decades ago has identified the key cost-related factors influencing cost overrun of Sri Lankan building projects as variation, extra work, fluctuation of price and currency, day works and other

Failing to adequately select the winning contractor can lead to problems in the project delivery phase such as bad quality and project delay; which ultimately results in cost overruns. There are two strategies involved with selecting contractors: one is the lowest tender, the other is called best value. Selecting the lowest tender is straightforward; the latter strategy would involve scoring the contractors' tenders on price and quality and ranking them. The aim of this research is to provide a model of determining the probability distributions of cost and time arising from choosing different

The main concern of a construction client is to procure a facility that is able to meet its functional requirements, of the required quality, and delivered within an acceptable budget and timeframe. The cost aspect of these key performance indicators usually ranks highest. In spite of the importance of cost estimation, it is undeniably neither simple nor straightforward because of the lack of information in the early stages of the project. Construction projects therefore have routinely overrun their estimates. Cost overrun has been attributed to a number of sources including technical error in

Cost overrun is one of the most important problem that encounter Real Estate projects success, since it reduces the contractor’s profit and sometimes lead to enormous losses. Cost overruns occur in every real estate project while the magnitude varies significantly from project to project. Throughout this research we tried to gather and analyze the main factors which cause cost overruns in real estate projects such as the factors determining percentage overrun include the financial condition of the owner ,the cash flow of the contractor, material cost increase, competition at tender stage, the

This study analyzed the historical trends in change orders (COs) associated with the Indiana Department of Transportation (INDOT) highway contracts. It also investigated correlations between COs and base factors (district, project type, contract type, award amount, geographical area (rural vs. urban)), and sought to understand the effect of the root causes but not to predict CO based on root causes. Unlike the base factors, the root causes are unknown prior to construction. The study developed models that forecasted CO characteristics—CO likelihood, CO frequency (count), and CO severity (magni

Inspection of pipeline field girth welds during pipeline construction is accomplished by film radiographic: methods. Film radiography of materials is a 70 year old technology. There have been many advances in that 70 year history in equipment and films, but the process of making the radiograph is essentially the same. The film radiography process is time-consuming, costly, environmentally impacting and very operator (inspector) dependent. There are recent and almost daily advances in technologies using x-ray imaging other than film. Double-jointed pipe welds at pipe mills and at double-joint o

We demonstrate that the use of Performance Frameworks for the procurement of construction projects by public sector organizations in the UK (specifically, in England) leads to significantly improved outcomes in terms of time, cost, quality, sustainability and closer relationships, than the traditional ‘open tender’ approach of procuring discrete projects, individually. We identify the factors that lead to such improvements. We label these: supplier’s task performance factors (project staff, execution approach, competence of firm and structure of firm); supplier’s contextual performance factors

In the article researched the experience of licensing of nuclear power plants of member states of the EAEU, both already having functioning nuclear power plants and planning its construction. It noted the different approaches of states to the licensing of the activity in this area, which can lead to increased time and unnecessary increase in the cost of construction of nuclear power plants. On the basis of the analysis it makes the conclusion on the necessity of harmonization of the process of licensing activity of nuclear power plants in member states of the EAEU, as well as it exprecces an o

High productivity mechanized welding processes, such as variants of multi-wire pulsed-gas metal arc welding (GMAW-P) have become increasingly popular due to their high production rates. Compared to the conventional single-wire GMAW processes, the high-productivity pro-cesses are more complex in welding procedure design, qualification, and field welding. The characteristics of these high productivity processes are different from that of the traditional sin-gle-wire/single-torch GMAW or shielded metal arc (manual) welding (SMAW) processes that have dominated pipeline construction in the past.

The importance of obtaining quality I-O tables for the GTAP Data Base has prompted the need for a method to compare contributed I-O tables. Comparisons are useful for a number of reasons. a) Time comparisons can be used to show how an economy has changed over time. b) Country comparisons may be used to show differences in cost or use structures between countries. c) Comparisons may also be used to highlight errors in construction procedures or mappings and therefore assist us in improving the quality of the data. In this document we look out how entropy can be used to compare I-O tables. The p

Transportation has an enormous impact on the U.S. economy and on the lives of all Americans. Many modes of transportation rely on pavement, but pavement conditions deteriorate over time because of the combined effects of traffic and climate. Exposure to moisture often causes premature failure of asphalt pavements as it reduces the stiffness of the asphalt and enables stripping of the asphalt from the aggregate. This research evaluates the effectiveness of clay nanomaterials (i.e., nanoclays) in improving the resistance of hot mix asphalt (HMA) to moisture damage and compares the enhancement re

Housing issues usually play a major role in urban studies, but are often overlooked as a factor in rural development. This policy brief explores aspects of the dynamics of the ‘frozen’ rural housing market in the Nordic Region, with a specific focus on the role of financing, the part played by municipalities and the potential benefits of a larger rental market.Housing is generally seen as a human right, a consumable that serves as the framework for our lives. However, at the same time, real estate is a financial commodity on the market. In many rural areas, the market value of houses is low –

Finite and decreasing landfill space on Army installations is a significant concern. Efficient waste management is essential for achieving resiliency and extending the lifespan of remaining landfills. The purpose of this demonstration was to conduct independent performance tests of small unmanned aircraft systems (sUAS) and their utility for providing landfill assessments in remote areas where physical presence is either dangerous or inefficient. An active, near capacity construction and demolition (C&D) landfill at Fort Gordon, Georgia, was identified for the demonstration. The flights, d

External coatings are routinely used to protect transmission pipelines from corrosion; however, coatings may degrade or disbond over time enabling corrosion to occur. Transmission pipeline operators often use magnetic flux leakage (MFL) in-line inspection tools to detect metal loss corrosion defects. Rather than finding the cause of a problem, failure of the coating within a corrosive environment, MFL corrosion surveys only find the result of the problem, corrosion defects that may permanently alter the pressure carrying capacity of the pipeline. Stress corrosion cracking (SCC) can be detected
