“…Gurgun and Koc (2020) report that compliance to schedule requirements was topmost among clients' performance criteria in GCPs. However, it has been proven that projects adopting GCPs are often more susceptible to schedule overruns compared to conventional construction projects (Bakchan et al, 2019), thus impacting negatively on CS on green construction projects. In view of the leanings from the literature reviewed, it is hypothesized as follows: H1 GCPs has a negative signi cant effect on CS.…”

Studies have proved that Client Satisfaction (CS) is greatly affected by the nature of construction practices carried out on site. However, not much attention has been given to CS in projects that adopt green construction practices (GCPs). This study examines the effect of GCPs on CS, and the means by which CS can be achieved through health and safety performance (HSP). This study also analyses how the relationship between HSP and CS could vary depending on the level of GCPs adopted. A questionnaire with 27 items drawn from literature was used in collecting data from class A contractors in Nigeria. The study’s hypotheses were tested using the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique. The findings of the study reveal that GCPs has a positive effect on CS. HSP proved to only partially mediate the relationship between GCPs and CS. The findings also show that the effect of HSP on CS is moderated by GCPs with the stronger effect from projects with low adoption of GCPs. The study findings highlight the pivotal role of HSP in ensuring CS in construction projects that adopt GCPs while also making theoretical and practical contributions to guide policy makers, scholars, and contractors.

“…This platform integrates dynamic resource management at the project level and decision-making support. Bakchan et al (2019) sought to outline the conceptual interactions that define the integration of construction waste management (CWM) and BIM with construction management. The authors proposed a multi-dimensional framework that provides guidance on CWM applications such as CW disposal scheduling, disposal cost estimation, on-site reuse, and allocation of waste bins.…”

Recently, new methods and technologies, including building information modeling (BIM) and lean management, have been introduced to the construction industry. Their objectives are to increase collaboration, ensure smooth flows of information, improve productivity, reduce different types of waste, and stabilize production. These constraints have forced the industry to gradually change by applying more adapted operational processes and contractual models that focus on value and by integrating the design, construction, and operation phases. Traditional scheduling methods based on activities modeling have become less adapted to this new reality. As a result, complementary concepts have emerged, particularly the Last Planner system, takt time, space planning, and spatiotemporal scheduling. This paper presents an extensive review and an assessment of the state of the art of the spatiotemporal planning of construction projects. The paper categorizes the research efforts, presents a timeline of the most significant scientific developments in this domain, and addresses their possible impacts on the construction industry.

“…Meanwhile, few studies have investigated the quantity of waste generated at different construction stages. In recent years, building information modeling (BIM) was leveraged to estimate CW (Bakchan et al, 2019; Kim et al, 2017; Won et al, 2016). However, a database including the WGR, embedded in the BIM model, must be built first according to the aforementioned qualitative or quantitative methods.…”

Estimation of construction waste generation is critical to construction waste management decisions. However, current construction waste estimation methods have various limitations (e.g. small samples). To address those limitations, this research conducts an empirical study to evaluate the waste generation rate of different types of waste at different construction stages. In this study, construction waste from 148 new-built residential construction sites in China were sorted and weighted on site and their waste generation rates were estimated separately. The results indicated that the amount of inorganic nonmetallic waste with a generation rate of 16.59 kg m−2 was the highest among the five types of waste (i.e. inorganic nonmetallic waste, organic waste, metallic waste, composite waste, hazardous waste), while the waste generation rate for the underground construction stage, which was 27.57 kg m−2, was the highest among the three stages (i.e. underground stage, superstructure stage, finishing stage). Compared with previous data, the new waste generation rate proposed in this research can better estimate the actual waste generation situation in construction sites, which provides reliable information for proper decision-making. Furthermore, based on the result of the empirical study, some recommendations for construction waste reduction are proposed.
