Detecting the most appropriate delay analysis methods for mega airport projects

Abstract

PurposeThis study aims to detect the most appropriate delay analysis method in mega airport projects.Design/methodology/approachFirst, the criteria affecting the selection of delay analysis methods were detected through an in-depth literature review and an expert panel, which was conducted with 12 experts who have experience in delay analysis domain in mega airport projects. Later, fuzzy VIKOR (VIsekriterijumska optimizacija i KOmpromisno Resenje) approach was conducted by considering the detected selection criteria and the most common delay analysis methods.FindingsWindows Analysis method was detected as the best option for mega airport projects. It was followed by Time Impact Analysis (TIA), collapsed as-built analysis, as-planned vs as-built method and impacted as-planned method, respectively.Originality/valueEach project has its own characteristics and thus requires specific management techniques; therefore, selecting a delay analysis method without considering the project types and size may cause conflicts between the contracting parties. On the one hand, numerous fruitful studies concerning delay analysis methods have been conducted in the literature, but on the other hand, none of them has considered project characteristics in terms of project size and type while selecting the most appropriate delay analysis method. Moreover, the larger the size of a project is, the more vulnerable it is to encounter with delays. Mega airport construction projects are complex in their nature in that they are large size and involve multi-disciplinary processes; thus, they need special attention in the process of resolving delays. This study intended to fill this gap in the literature by focusing on selection of the most appropriate delay analysis method for mega airport projects, and it is clear that considering the project type and size in the selection of delay analysis methods will provide more reliable outcomes.

Indispensable Delay Analysis Method Selection: An Integrated Ahp-Rii Approach

“…By applying the SAW approach, seven key factors in the level 2 and 23 attributes in level 3 of developed DMM were analyzed in terms of significant index and important index, respectively, and the validation of DMM is applied via a series of case studies and a professional panel. Furthermore, the study by Cevikbas et al [13] was conducted through an intensive literature review and a 12-expert panel to detect the further factors impacting the selection of DAM, a total of 26 criteria were grouped into six categories and analyzed via the Fuzzy VIKOZ method for the selection of the appropriate delay analysis approach for mega airport projects. Notwithstanding, since projects are one-of-a-kind by nature, the DAM alone shall not be the best for all project circumstances under certain conditions.…”

“…The project planners and schedulers' capabilities normally are performing scheduling and control management well versed, and they are also aware of truly explaining the delays as the impacts of delays on the critical path and non-critical path of the project as well. Usually, in the previous studies [12,13], the authors adopted many professionals whose jobs were in project planning, controlling, technical office, commercial, and contract managers and those are highly unsuitable identification.…”

“…More importantly, the combined analytical hierarchy process -relative importance index (AHP-RII) approach has been analyzed to find out the best DAM in the given delay factors and conditions for construction projects. As a basic tool for decision-making, the AHP is the most widely used, simplest, and most accurate method [13,17]. Its integration with the RII approach in this study ensures that the results are reliable, highly accurate, credible, and consistent, making them exceptionally valuable in practical applications [18].…”

“…However, these studies have adopted both inherently limited delay factors (criteria) and DAMs (alternatives) that cannot be capable of seeking a greatly appropriated DAM. More recently, the fuzzy VIKOR (VIsekriterijumska optimizacija i KOmpromisno Resenje) approach was conducted by considering the detected selection criteria and the most common DAMs for mega airport projects [13]. The research typically reached the gaps in the literature by paying much attention to selecting the most fundamental DAM and considering the project type and size in the selection of delay analysis techniques will provide more reliable outcomes.…”
