Abstract
The contract administration process is inevitably complex, and improper performance of the associated tasks and procedures may lead to disputes between the contracting parties whilst further driving against the sustainability bottom lines. Therefore, this paper proposes an assessment tool to improve the implementation of construction contract administration (CCA) through a multi-dimensional construction contract administration performance model (CAPM), construction contract administration performance index (CCAPI), and a mobile software to assess the CCA performance at the project level by integrating the crisp value of the fuzzy set theory within a second-order confirmatory factor analysis of the structural equation modeling technique. A hybrid mobile application (CAPM) is developed using the Ionic framework which can run either in full model mode or short model mode with 93 and 33 key construction administration factors, respectively. Assessment of sustainability practices in the area of contract administration is a part of the holistic model and CAPM defines 13 major key indicators relevant to social and environmental sustainability while economic sustainability is scattered over the rest of the CAPM indicators. The CAPM is practically implemented in 13 international construction projects and the results reveal that the proposed tool is reasonably captured in the different performance levels of CCA, and we conclude a low level of implementing in risk management. As part of the holistic model, assessment of sustainability practices in the area of contract administration is separately discussed and the study reveals the need to improve the environmental and social sustainability practices in contract administration.
Highlights
While the construction industry is as an enabler for achieving nationwide goals in modern society, the construction projects have a substantially high rate of business failure, bankruptcy, delays, losses and budget overruns, deviation from standards, quality issues and waste of resources [1]
The current study proposes a novel application of the fuzzy structural equation modeling (FSEM) to assess the influential factors of construction contract administration and provides an analytical tool to determine the CCA performance in 11 project management process groups
This paper proposes a construction contract administration performance index (CCAPI) based on a multi-dimensional systematic construction contract administration performance framework (CAPF) and a fuzzy structural equation model (CAPM)
Summary
While the construction industry is as an enabler for achieving nationwide goals in modern society, the construction projects have a substantially high rate of business failure, bankruptcy, delays, losses and budget overruns, deviation from standards, quality issues and waste of resources [1]. The CCA team will have a contribution to the economic principle of sustainability by the timely response to queries; timely issuance of supplementary information; and timely management of operational issues These sample key activities will reserve the additional costs generated from delay in decision making or unresponsive response. The CCA can prompt the social principle of sustainability by: Keeping workers safe through auditing of the contractor’s safety system; enforcing policies to maintain health of workers, instructing contractors to perform urgent works required to maintain safety, monitoring public interference arrangements and minimizing their impact by the project, and increasing capacity building of the CCA staff. The CAPM is practically examined in 13 international construction projects and the results are presented in the study
