Analysing factors affecting delays in Indian construction projects

As a result of the loss of financial resources and the need to optimize projects, academics, politicians, and the construction industry have become increasingly aware of the challenges presented by the frequent time and cost overruns and reduced quality of construction projects. The purpose of this study was to analyze the factors that project managers experience as having the greatest effect on time, cost, and quality, and to discover whether the effects of these factors are significantly different from each other. A questionnaire with 26 factors identified from interviews was sent to the full population of publicly employed project managers. Factors were ranked using the relative importance index and tested for significant differences using Friedman’s test. Wilcoxon’s test was used in a post-hoc analysis. From the findings it was determined that the most influential factor for time is unsettled or lack of project funding; for cost, errors or omissions in consultant material; and for quality, err...

Factors affecting schedule delay, cost overrun, and quality level in public construction projects

Target costing is an effective management technique that has been used in manufacturing for decades to achieve cost predictability during new product development Adoption of this technique promises benefits for the construction industry as it struggles to raise the number of successful outcomes and certainty of project delivery in terms of cost, quality and time Target value design is a management approach that takes the best features of target costing and adapts them to the peculiarities of construction The concept of target value design is introduced based on the results of action research carried out on 12 construction projects in the USA It has been shown that systemic application of target value design leads to significant improvement of project performance—the final cost of projects was on average 15% less than market cost The construction industry already has approaches that have similarities with elements of the target value design process or use the same terminology, eg partnering and targ

Target value design: using collaboration and a lean approach to reduce construction cost

Once a construction projects fails in achieving effective cost performance, it will result to cost
overruns. These overruns are caused from several factors which are very important to uncover for improving
the cost performance. In Malaysia, not many research works have been carried out on studying cost
performance factors. Hence, this study was conducted to identify the significant factors causing cost overrun
in large construction projects in Malaysia. Questionnaire for the survey was developed based on 35 common
factors of cost overrun identified from literature work. These factors were grouped in 7 categories and validated
by interviewing five experienced personnel of construction industry. The feedback of from the survey resulted
in receiving 262 sets of completed valid responses against 400 questionnaires distributed amongst contractors,
consultants and clients involved in large construction projects. The data from the questionnaire was analyzed
statistically. Relative importance index method was used for hierarchal assessment of factors and found that
the top 3 most significant factors of cost overrun are fluctuation of prices of material, cash flow and financial
difficulties faced by contractors and poor site management and supervision. These factors belong to two
categories i.e., contractor's site management and financial management category, thus improvements in these
categories are paramount for controlling cost overrun in construction projects.

Risk ranking and analysis in target cost contracts: Empirical evidence from the construction industry

Despite the availability of various control techniques and project control software many construction projects still do not achieve their cost and time objectives. Research in this area so far has mainly been devoted to identifying causes of cost and time overruns. There is limited research geared towards studying factors inhibiting the ability of practitioners to effectively control their projects. To fill this gap, a survey was conducted on 250 construction project organizations in the UK, which was followed by face-to-face interviews with experienced practitioners from 15 of these organizations. The common factors that inhibit both time and cost control during construction projects were first identified. Subsequently 90 mitigating measures have been developed for the top five leading inhibiting factors—design changes, risks/uncertainties, inaccurate evaluation of project time/duration, complexities and non-performance of subcontractors were recommended. These mitigating measures were classified as: preventive, predictive, corrective and organizational measures. They can be used as a checklist of good practice and help project managers to improve the effectiveness of control of their projects.

Cost and time control of construction projects: inhibiting factors and mitigating measures in practice

Construction project control in the UK: Current practice, existing problems and recommendations for future improvement

In construction projects, the aim of project control is to ensure projects finish on time, within budget, and achieve other project objectives. During the last few decades, numerous project control methods have been developed and adopted by project managers in practice. However, many existing methods focus on describing what the processes and tasks of project control are; not on how these tasks should be conducted. There is also a potential gap between principles that underly these methods and project control practice. As a result, time and cost overruns are still common in construction projects, partly attributable to deficiencies of existing project control methods and difficulties in implementing them. This paper describes a new project cost and time control model, the project control and inhibiting factors management (PCIM) model, developed through a study involving extensive interaction with construction practitioners in the UK, which better reflects the real needs of project managers. A set of good practice checklist is also developed to facilitate implementation of the model.
