Özet:
In this thesis, as part of information gathering concerning delay analyses in the
construction industry, the current problems, gaps and trends were detected under
two researches, which enabled to set the core objective of this study. Firstly,
Scientometric Analysis was conducted via VOSviewer software. It was concluded
that there are gaps and trends in literature towards developing new delay analyses
because of the challenges and drawbacks of the existing delay analysis methods.
Secondly, an expert review meeting with 7 experts was conducted and common
themes of the participants’ views are presented in this study to detect further
problems concerning delay analysis methods. All in all, in this study, the problems
related to current delay analyses were highlighted. It is clear that it is difficult to
conduct reliable analyses without overcoming the detected problems. Therefore,
in this study, it is aimed to develop a new delay analysis method named Modified
Schedule vs Modified Updated Schedule (MSvsMUS), which overcomes the
detected drawbacks to be able to compute the project delays and apportion the
project delays to the contracting parties systematically and efficiently. Following
the development of the method, the method was validated through a hypothetical
study, a real case study and an expert panel. On the whole, MSvsMUS was
regarded as applicable by all of the participants. Afterwards, the developed
method was integrated into 4D-BIM software, namely Bexel Manager by using the
programing language of ‘C++’. The integration of the method into 4D-BIM
software was successfully tested with a real dwelling project as a case study.
Developing a new delay analysis method and integrating it into BIM software, this
study is believed to provide a significant improvement in the construction industry
by presenting solutions for detected problems faced in the current delay analysis
applications.
