“…The literature was reviewed using the broad set of search Since a significant time is spent during the construction phase of a PT project, it is realistic to expect that most delays occur in this stage. It is logical, therefore, to study the causes of delays in construction projects, and most specifically non-power linear projects, as foundational in finding causes of PT project delays [5]. The applicability of the factors causes delays in power generation vis-à-vis PT projects increases further than linear construction projects, as these projects consist of the construction of stations and substations that also exist in PT projects [5].…”

“…PT is at the heart of the power sector, and project management in the PT sector is challenging because of the presence of high-voltage PT lines and right of way (RoW) issues, which makes PT projects significantly different in scope from other linear power and non-power projects [5,6]. Also, PT project management is thought-provoking because they are usually sited in remote areas, away from existing establishments such as electricity and water supplies, and thus entails careful planning [7].…”

“…Despite the criticality of PT projects, the research on the PT projects' schedule management is embryonic and has not revealed all the key factors involved. More precisely, Pall et al's (2016) [5] comprehensive literature review revealed that PT projects have their own unique causes of delay beyond power generation, power distribution, and other non-power linear construction projects, and recommended an empirical investigation into the causes of delay and relationships between them. In response to Pall et al's (2016) [5] recommendation, an updated review of the latest literature still shows that there is no empirical study on the causes of delay in PT projects.…”

Power transmission (PT) projects are vital for the power sector. However, worldwide PT projects experience delay. There is an urgent need to understand the unique causes of delays in PT projects. This paper presents the first empirical study on causes of delays in PT projects via a comprehensive literature review. Based on this literature review, 63 potential delay factors are identified and divided into ten major groups. These include two new groups of delay attributes, comprising sector-specific factors (SSF) and general factors (GF), where SSF pertains solely to PT projects and GF contributes to minimizing the bias of project participants. A questionnaire survey of 311 PT stakeholders is conducted to determine the overall ranking of the delay factors using the relative importance index. The results indicate that SSF, GF, and external/unavoidable factors are the most critical groups of delay factors, with the top-ranked factors being right of way problems of transmission line (TL), frequent changes in TL routes, and accessibility to the TL tower locations. Finally, recommendations are made to help minimize time overruns in PT projects, as well as in other linear power and non-power construction projects in general.

“…The bridge project was suffered from two years delays time and the cost had increased about RM1.5 million because of location issues, increasing of material cost and other unexpected events [8] [9]. Schedule control is the main key to a successful project [10]. Time overruns give negative impacts on the project and all the involved construction parties.…”

Structural Equation Modelling (SEM) has been widely used in science social area compared to construction engineering and management field especially in area of delay construction. SEM is a second generation multivariate analysis that has an advance features compare to first generations of analysis tools. First generation techniques suffer with some assumptions such as error measurement is neglected, only observed variable allowed, only for simple model and other limitations. In construction delay study, comprehensive and complex analysis which involves hidden variables need to be considered to get precise results. Therefore, the main objective of this paper is to review the importance of applying SEM for construction delay study. Various papers which were taken from construction delay and construction management studies has been reviewed to observe the suitability of SEM for construction delay study. Outcome of this review reveals that SEM can include latent variable in the analysis model and consider of error measurement as integral part of the model as well as simultaneously analyse theory and measurement in a structural model while it is unobtainable for first generation techniques. This review proves that SEM can be an appropriate analysis tool for construction delay study.
