Non-Conformance is defined as deviation in terms of quality during the construction execution. Whenever there is a deviation in quality, a non-conformance report (NCR) is issued. This non-conformance leads to rectification, repair or rework of an activity that ultimately result in time and/or cost overrun. Also, deviation in quality can have a direct or indirect impact on the successor activities and subsequently on the project performance. Every NCR has its origin with an activity and there exist dependencies among the activities and NCRs. The objective of the present study is to capture the dependencies among activities and NCRs using a structured approach that can be utilized to estimate the total project duration, which is inclusive of the delays due to nonconformances. To achieve this objective, a case study-based MDM (Multiple Domain Matrix) solution methodology has been proposed and the same has been demonstrated with the case study of a metro project. This NCR-activity mapping using MDM is effective in planning repetitive projects.
