Abstract

A construction project is successful only if the target(s) is/are achieved as per schedule and following the baseline to the core. Any variations from these cause a delay and by which the project cannot be completed within a planned time. Also the delay results in expense to all the parties involved in the completion of a particular project. This often end up in clashes between parties, arbitration/ litigation and in certain cases can lead to the total abandonment of project. There are several factors attributed to the delay. These scenarios grab more attention in many construction projects. This is a common issue faced all over the world and India is no exception. This paper tries to identify the various factors attributing to delay of construction projects and their effects in Indian construction Industry. The research methodology includes literature review and questionnaire survey to identify and collect data. The data are analysed using SPSS software to know the factors which are majorly effects for delay. A questionnaire and personal interviews have formed the basis of this research. Factor analysis and regression modelling were used to examine the significance of the delay factors. The construction delays were grouped under seven major factors and each of these major factors are explored with sub factors under them. Factor analysis will be carried out to identify the influence of the delay factors. These findings will be used to overcome the delays in Indian construction industry in controlling the time overrun and cost overrun in construction projects.

Abstract

India is a country with enormous requirements of infrastructure development and up-gradation. The development of the country depends on building sustainable infrastructure with a challenge of getting it done real fast to catch up with the huge and rising demand. The role of the construction industry in the economic growth of a country is enormous and immeasurable. The challenge of providing needed quality infrastructure is in the hands of construction Industry. However in our country, almost all construction projects, suffer major delays and cost overruns. In some cases get terminated midcourse and do not get completed at all. Out of the total 766 central projects of value Rs 150 crore and more, 237 projects are delayed (~30.94%), while the cost of these projects have gone up from 10,68,206.97 crore to 12,73,650.02 crore (~19.20%)1.

The reasons for the delays and cost overruns on these projects are plenty. Delay in land acquisition, right of access, delayed financial clearances, delayed / in adequate designs, scope creep, incorrect estimates, etc. to name a few.

In a well-planned project, meticulous and thought of cash flow management and smooth project execution, has to go on hand in hand. Delays in construction projects as above can jeopardize the cash flow plan and disturb the working capital cycle ultimately turn a healthy, cash positive project into a cash negative sick project. This paper illustrates the impact of delays on net cash flow of projects also explains the importance of cash flow monitoring indicators, various cash flow mitigation strategies to overcome these problems.

Abstract

The high consumption of raw materials by the construction sector results in chronic shortage of building materials and the associated environmental damage. In the last decade, the construction companies have conducted various researches on the utilization of waste products in concrete in order to reduce the utilization of natural resources.

Use of construction wastes in concrete-making, will lead to greener environment. In this study, an attempt has been made to find the suitability of the ceramic wastes as a possible substitute for conventional natural fine aggregate in concrete. Experiments were carried out to determine the compressive and split tensile strength of concrete by partially replacing ceramic wastes in place of river sand and to compare them with that of conventional concrete made with natural fine aggregate.

The test results indicated that the workability of ceramic waste fine aggregate concrete is high and equivalent to that for conventional concrete. The compressive strength of ceracrete is slightly higher and the split tensile strength of ceracrete is almost equivalent to that of controlled concrete.
