Green site practices and environmental performance: how project complexity moderates the relationship

Abstract

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.

Green Construction Practices: Ensuring Client Satisfaction Through Health and Safety Performance

“…The signi cant positive effect of GCPs on CS observed in this study can be attributed to the monetary and non-monetary bene ts associated with the adoption of GCPs such as better project quality and greater productivity of construction workers (Karakhan & Gambatese, 2017). It has been reported that the non-adoption of GCPs could result in nes been imposed on the client, and could eventually lead to sealing off of the project site (Onubi et al, 2019), thus leading to extra cost and schedule overruns.…”

“…Even though the number of clients accepting to adopt GCPs has been on the increase, their choice to adopt these practices is passive, since they are been compelled by the government to do so (Shan et al, 2020). This could lead to a situation whereby they may not be satis ed as they ought to be when such practices are been adopted on their projects due to cost overrun, delays, increase in complexity, and risks (Onubi et al, 2019).…”

The moderating effect of project complexity on the relationship between organizational controls and cost estimation performance: A conceptual model

“…The moderator effect of project complexity has been used on project performances such as new product development, environmental performance, crowdfunding performance, and performance of international development projects [54][55][56][57]. The authors used project complexity as a moderator to the correlation between project events and project performance.…”

Effects of green construction on project’s economic performance

“…The performance of construction projects is largely dependent on the approach adopted in carrying out various site activities (Forster, 2014; Onubi et al , 2019b). It requires foresight and well thought out choice of construction practices and operations to guarantee the optimal performance of the construction project (Ajayi et al , 2017).…”
