“…Several researchers have revealed that the complexity of construction projects influences its environmental performance (Luo et al, 2016). The larger and more complex projects (the more suppliers, project stakeholders, site workers, engineers and activities inherent in the project) the more the likelihood of failure (Collins, Parrish and Gibson, 2017;Luo et al, 2016), subsequently highlighting the moderating effects of project complexity. In other words, green construction site practices, when implemented in a construction project (with diverse suppliers, project stakeholders, site workers, engineers, and activities) further poses the challenge of achieving projects' environmental performances.…”

The characteristics of a project that makes it hard to understand, predict, and manage its general behavior despite the availability of required information relating to the project dynamics is referred to as project complexity. A good knowledge of project complexity at the construction phase of a project, as well as a well thought out plan to manage complexity will determine how proficiently construction projects are planned, managed, and executed in an environmentally friendly manner. The level of complexity of construction projects to a large extent determines the performance or otherwise of the projects with regards to achieving specific environmental standards. At construction sites, the effects of adopting green site practices on environmental performance is largely dependent on the level of complexity inherent in the project’s construction processes. This study investigates the moderating effects of project complexity on the relationship between various green construction site practices and environmental performance of construction projects. A survey was conducted on class A contractors in Nigeria and 168 usable responses were received. The data were analyzed using the partial least squares structural equation modelling technique. The results show that project complexity moderates the relationship between waste management and environmental performance, and the relationship between materials management and environmental performance. But project complexity does not moderate the relationship between energy management and environmental performance. The study provides important theoretical and practical information for construction managers in understanding the dynamics involved in managing of projects with different degrees of complexity, while adopting certain green site practices with the aim of delivering projects with high degree of environmental performance.

“…There has been minimal literature dedicated to incorporating an engineering completion rating index to the project schedule and cost performance for oil and gas EPC projects. The most significant existing index models found were the project definition rating index (PDRI) by the Construction International Institute (CII) [7][8][9][10] and the front-end loading (FEL) index by Independent Project Analysis (IPA) [4]. These tools are mainly developed and utilized to define the level of completion of FEED, which is an engineering task prior to EPC detail engineering.…”

“…CII's PDRI is an alternate assessment tool to IPA's FEL as it serves the same purpose of measuring project definition from the conceptual design stage to the FEED stage of a project. The PDRI's hierarchical structure is comprised of three sections, categories, and elements [7,8,10]. Three sections include: (a) the basis of project decisions; (b) basis of design; and (c) execution approach to holistically evaluate the project value, scope, definition, and readiness for next stages.…”

“…Three sections include: (a) the basis of project decisions; (b) basis of design; and (c) execution approach to holistically evaluate the project value, scope, definition, and readiness for next stages. The PDRI has 8 to 15 types of categories for each section [7][8][9][10]. At the bottom of the PDRI hierarchy, each element specifies details that can be individually reviewed.…”

“…The most important PDRI review should be carried out prior to the EPC contract, which is the final investment decision (FID). The CII recommends that the cutoff score of the PDRI at the end of the FEED stage should be 200 as the performance of a project with a score higher than 200 was historically not satisfactory in terms of cost and schedule [10,12]. PDRI can help the owner manage project scope prior to a project authorization and/or the contractor identify incomplete elements related to project scope definition [13].…”

Engineering, Procurement, and Construction (EPC) contractors with lump-sum turnkey contracts have recently been suffering massive profit losses due to re-works and schedule delays in offshore oil and gas EPC megaprojects. The main objective of this research is to develop and implement a detail engineering completion rating index system (DECRIS) to assist EPC contractors to optimize fabrication and construction works schedules while minimizing potential re-work/re-order. This is achieved through adequate detail design development and results in minimizing schedule delays and potential liquidated damages (i.e., delay penalties). The developed DECRIS was based on findings from an extensive review of existing literature, industry-led studies, expert surveys, and expert workshops. The DECRIS model is an evolution, and improvement of existing tools such as the project definition raking index (PDRI) and front-end loading (FEL) developed specifically for the early stage of engineering maturity assessment (i.e., planning, basic design, and front-end engineering design (FEED)), prior to EPC projects. The DECRIS was evaluated and validated with thirteen sample as-built offshore megaprojects completed recently. When the DECRIS was applied to the completed projects post-hoc, a correlation (R-squared 0.71) was found between DECRIS scores and schedule/cost performances. This is much superior to the PDRI-Industrial model's correlation (R-squared 0.04), which was primarily devised for owners' basic engineering or FEED completion assessment. Finally, as a means of further validation, project schedule and cost performance of an ongoing project was predicted based on the correlations found on the thirteen completed projects. The resultant predicted schedule and cost performance was well matched with the current project performance status. Based on the accuracy of the DECRIS model found in the validation, said model is an effective prospective tool for EPC contractors to manage their engineering and procurement/construction risks during the initial detail design stages. of the total global oil supply [1]. In 2011, shale oil and gas were introduced to the oil and gas market with the development of cost-effective hydrofracturing technologies. This has led to an over-supply of oil and gas and, consequently, an era of low oil prices decreasing major oil companies' profits [2].An offshore project requires a significant amount of early investment for drilling and production facility design and construction. To combat lower revenues and increase profits, major oil companies have placed a great deal of attention on cost-saving strategies in these early stages for offshore oil and gas projects [3]. However, these strategies are often poorly planned and implemented, leading to inadequate resource allocation, and improperly accelerated design and construction. This all results in poor quality of work, schedule overrun, and even safety-related accidents on site [2].Therefore, how can planning be improved? Merrow collected and analyzed project pe...

Currently, there is a surge in the adoption of green construction practices (GCP) to address and attempt to alleviate the adverse effects of construction activities on the natural environment. The current research surrounding sustainability in the industry has witnessed a notable surge in efforts, primarily driven by a growing consciousness of environmental concerns. In this context, it is worth noting that the focus of assessment schemes in developed countries has predominantly gravitated toward economic and environmental factors, with relatively less emphasis placed on social performance (SP). Many researchers have underscored this disparity, highlighting the need for a more comprehensive approach encompassing all three sustainability dimensions. Hence, the present research examines the effects of green construction practices on economic performance (ECP) while considering the mediating role of environmental performance (EP) and SP. The results showed no direct impact of GCP on ECP. However, the mediating role of SP and EP in the association between GCP and ECP was found to be statistically significant. The present study provides several implications. This study presents empirical evidence that implementing GCP yields several benefits for contractors, including cost reduction in waste management, legal expenses, and energy consumption. These cost savings effectively offset the initial investment required to implement GCP, enabling construction projects to attain ECP thresholds. This study provides a significant contribution to the expanding corpus of knowledge concerning green building site practices and construction management. It offers novel insights into the influence of a project's EP and SP on its economic feasibility. Furthermore, this research study has effectively showcased the positive impact of GCP on construction projects' environmental construction performance, particularly concerning environmental and social considerations.
