“…Such uncertainty, fuzziness, or vagueness results from the absence of distinctness (Ocampo et al 2018). In the way humans perceive the world, vagueness, the opposite of exactness, cannot be avoided (Martin and Ramjarrie 2021). When making real-world decisions, it is preferable to use fuzzy numbers because linguistic preferences reflect perceptions (Bui et al 2020).…”

“…Comparatively, descriptive specifications or performance specifications state the code or standard by which the designer should abide. The degree of elucidation defines the various DB categories forming a contract (Martin and Ramjarrie 2021). Because design-build projects can still be in the design stage when construction occurs, and the programming of materials becomes more complicated because the quantity and quality are not defined by the client before a contractor is engaged.…”

As projects evolve into complex and specialized temporary initiatives, accountability shortfalls in material flow are a major reason for schedule and cost overruns in construction. To date, researchers and practitioners are unresolved regarding the causes of material handling challenges and eminent solutions to improve material flow accountability. Consequently, inefficient supply chain management practices persist, leading to ineffective handling methods. This research, therefore, focused on identifying critical material challenges encountered by contractors and presented solutions to alleviate schedule and cost overrun failures. The fuzzy Delphi approach was used to refine opinions and achieve group consensus from 15 specialists on the ranking of material handling problems and potential solutions associated with designbuild projects. The research revealed that complexity, material flow, and lack of information sharing are the top three main causes of onsite material problems. Potential solutions identified were a faster response mechanism (as an alternative to a slower build schedule), increasing material handlers' worker power, subcontractors' involvement in the procurement process, and prefabrication. The research highlighted subcontracting as a material handling paradox as apart from being a solution, it creates non-value-added costs in the supply chain and often inappropriately transfers risk. The findings showcased the potential to improve onsite material handling praxis by considering decisionmaking uncertainties in material flow and recognizing the importance of procurement methods in construction supply chain solutions in resolving scheduling and cost inefficiencies.

Construction companies consider it a priority to prevent occupational accidents and diseases, despite this, accidents in this sector prevail. This study presents OHSYS, an expert system specialized in the prevention of occupational safety in the construction of residential buildings, which evaluates a building project and it is recommended to security officer, actions to mitigate occupational risks. The results show that the number of recommendations increases on average by 7 and 13 for OSH levels of 90% and 100% when using OHSYS. In addition, the satisfaction, usability, and efficiency survey applied to 10 experts show that OHSYS has a very high score (4.5 out of 5).

“…Increasingly used in construction management research, the Delphi method is a structured communication technique originally developed as a systematic, interactive forecasting method that relies on a panel of experts answering questionnaires in consecutive Rounds until convergence, with the facilitator providing a summary of their judgments to the group in the form of the mean or median response in each Round: as uncertainties arise from the judgments of decision makers, this method accounts for interpersonal uncertainty and variability in one's opinion (Martin & Ramjarrie, 2021). Of particular relevance here is the increasing use of the Delphi method in such construction management research as graduate education (Pathuri et al, 2020), company performance (Mansour et al, 2020) and contract administration (Gunduz & Elsherbeny, 2020), as well as contractor selection (Mahdi et al, 2002), in terms of performance criteria (Gunasekara et al, 2021), safety criteria (Gharedaghi & Omidvari, 2019), public contract criteria (Hajek et al, 2017), effectiveness factors (criteria) (Lajimi et al, 2018), construction supply chain pre-qualification and selection criteria (Mahamadu et al, 2017), and project source criteria (Faraji et al, 2020).…”

PurposeThe purpose of this study was to prioritize the appropriate generic contractor selection criteria for Engineering–Procurement–Construction (EPC) projects in the construction industry.Design/methodology/approachProceeding from a review of previous studies and validation by a small group of experts, a preliminary set of 16 criteria was first identified. This was followed by three rounds of Delphi surveys: firstly, with 64 experienced participants confirming the relevance of the 16 criteria; secondly, with a reduced subgroup of 47 more experienced participants scoring the importance of each; and finally, providing the opportunity for these 47 to revise their scores in the light of knowing the aggregated results of the previous round.FindingsThe results show the consensus view, of which the most important criteria are ranked as past performance, project understanding, technical attributes, key personnel, health and safety, past experience, time, management, financial, contractual and legal, quality, cost, relationships, environmental and sustainability, organizational and industrial relations, and geographic location.Originality/valueThe findings are useful for both practitioners and academics in making a significant contribution to the body of knowledge of the EPC process. This will assist in providing a better understanding of criteria importance and pave the way to developing an EPC contractor selection model involving the criteria most needed to objectively identify potential contractors and evaluate tenders.
