Delays in construction projects are inevitable & result in disputes, litigations, and claims among different parties and poorly influence scheme accomplishment in respect of the duration of time, quality & price. Most huge schemes are finished with a delay than the parties' agreed-upon dates for several reasons. These sorts of delays can have a crucial financial influence on the scheme. In general, delays are a basic loss condition: All the parties lose one way or the other and there are no actual winners. The statuses of each party are at stake as well. For the evaluation of delay causes and their effects on construction schemes, a detailed study is done on the causes of delays in construction projects and techniques for analyzing them and approaches to evaluate. To evaluate the major delays observed by Project Manager, Proprietor, Consultant, and Contractor during the construction phase a questionnaire is prepared and circulated among 40 nos. of industry-related persons (30 nos. working at the site). The questionnaire was prepared with the help of a comprehensive literature review as well as with the help of industry project experts. From the response to the questionnaire, it is identified that there are majorly 9 groups (such as Contractor, Architect, Project Team, Proprietor, Consultant, Equipment, Material, Labor & external factors) under which there are 67 delay causes are found. For evaluating the main reason for delay a method is developed on ranking accordingly as per the results obtained through questionnaire surveys dependent on the relative importance index method. Through questionnaire results, we got a clear picture that most delaying factors are repeated in every project such as financial issues, shortage of material, labor, improper supervision, communication, real-time changes, etc. To avoid delay, certain recommendations are also given accordingly.
