Time Impact Analysis on Construction Projects

Time impact analysis (TIA) is a forward looking tool. This analysis takes into account a schedule that does not include a delay & one which includes delay. The difference between these two schedules is considered to be the impact of delay for time duration considerations. The research includes application of TIA on two construction projects and then finding the reasons for delays of those projects. Along with the learning?s of case study, i.e. the discovered causes for delays & from the literature survey done, a questionnaire was prepared & questionnaire survey was carried out. A total of 28 causes were identified and classified under 8 major groups. The total numbers of respondents in this survey were 68, out of which 32 were clients, 12 were consultants & 24 were contractors. This questionnaire was circulated among the professionals in the industry to find the factor which contributes the most to the construction project delays. Top ten causes affecting delays the most were identified. This research would be helpful for the stakeholders to act on the critical causes & further reducing the delays.
