| dc.description.abstract | Concurrent delay is a very complex and controversial topic in the construction
industry. Analysis of the concurrent delays became challenging due to the
absence of clear provisions in the standard form of contracts. Meanwhile, project
parties try to pass the contractual liability to the other parties and make the
situation more problematic. The lack of knowledge on the concurrent delay
analysis procedure among project parties would be another reason to increase
the complications. Even though various delay analysis techniques and
approaches are available in the construction industry, all of them cannot be used
to assess any concurrent delay situation. Hence this study aims to investigate
the adaptability of various techniques and approaches for concurrent delay
analysis in the Sri Lankan construction industry. The research was conducted
based on expert interviews by adopting a qualitative research approach. The
collected data was analysed via content analysis using NVivo software. Research
findings revealed that the lack of proper record-keeping, the ambiguity of
concurrent delays, and the lack of advanced scheduling software as the main
challenges of concurrent delay analysis in the Sri Lankan construction industry.
Further, the time impact analysis method and window analysis method are the
most recommended Critical Path Methods (CPMs) for concurrent delay analysis
in the Sri Lankan context. However, in some cases, one CPM is not adequate to
analyse the entire delay of a project and research findings recommended to use
a combination of CPMs in such situations. Ultimately, the study concluded that
the selection of concurrent delay analysis techniques depended on the type of
construction schedule of the project and available project records. | en_US |
