| 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 recordkeeping,
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 |
