Construction Change Order Management Project Support System Utilizing Delphi Method

Abstract

Change orders are a major challenge in the construction industry due to the associated time and cost impacts. Thus, managing change effectively assists in alleviating cost overruns and delays. Avoiding change orders and controlling them during project phases requires comprehensive research on the factors affecting the change orders management (COM) performance. This study contributes to existing knowledge by introducing a COM performance measurement framework to help construction professionals evaluate, track, and manage COM performance. A comprehensive literature review, personal meetings, and the Delphi technique are utilized to identify 49 performance factors, categorized into 7 COM groups. 13 Delphi panel members are selected according to purposive sampling technique. The collected data are examined through normality and reliability tests and then analyzed by Spearman’s correlation coefficient, score percentage, and the mean to standard deviation ratio to decide whether to continue with the Delphi method. Consensus between the panelists is reached after the second round of Delphi by the utilization of nonparametric statistical tests. The Delphi study results are followed up by measuring the inter-rater agreement (IRA) and ranking the COM performance factors using the sum rank weighting method. Finally, an operational support system framework that takes into consideration the project life cycle of a project is developed to manage and control these factors to decrease disputes between project parties that occur due to improper COM performance.

Factors that favor or hinder the acquisition of a digital culture in large organizations in Chile

“…In addition, it uses anonymity to avoid group think and the possibility of gathering qualitative and quantitative data to enrich the analysis process ( Almenara and Moro, 2014 ; Reguant Álvarez and Torrado Fonseca, 2016 ; López Gómez, 2018 ). The Delphi method is widely used for organizational studies ( Bhardwaj and Patnaik, 2019 ; García-Vidal et al, 2021 ; Kerpedzhiev et al, 2021 ; Vax et al, 2021 ) and project management research ( Cafiso et al, 2013 ; Gajić and Palčič, 2019 ; Naji et al, 2022 ), including areas as different as civil engineering ( Kermanshachi et al, 2020 ), health ( Nasa et al, 2021 ), technology ( Andersen, 2022 ), among many others.…”

Enhancing Micro-Tunnelling Activity in Infrastructure Construction Adopting Hybrid Lean Approaches: A Case Study

“…The authors followed the case study methodology in developing this research paper, case studies are suitable for studying phenomena in their real-life contexts where researchers have not previously studied (Naji et al, 2022). ASHGHAL introduced Lean Construction to enhance infrastructure projects performance and delivery.…”

The Impact of Change Orders Caused by Legislative Changes on Program Management in the UAE Construction Industry

“…Some of the reported strategies to ensure the proper implementation of safety and environmental laws in construction projects include the use of Building Information Management (BIM) systems to ensure project compliance with the requirements of safety management, by ensuring accident prevention and avoiding personal injury or property damage, as well as environmental management, which is necessary to confirm that projects follow laws and regulations relating to the environment [61]. Additionally, the reported mitigation strategies in the literature that focused on tackling change orders were mainly divided into Design Management (e.g., sufficient stipulated time for design and establishment of project management plan), Quality Management (e.g., periodic reviews of project requirements), Documentation Management (e.g., reviewing the sufficiency of contract documents for changes), Financial Management (e.g., detailed breakdowns and pricing of change order components), Dispute Resolution Management (e.g., establishment of a claims and disputes resolution system as set out in the contract), Communication and Relationship Management (e.g., regular meetings between contracting parties to discuss changes), and Procurement Management (e.g., early identification of lead items during design stage), to name a few [62][63][64][65][66].…”
