Purpose Labour efficiency is the key component for long-term sustainability of construction firms. Recent studies show that modernising organisational/managerial processes necessary to raise labour in many emerging nations. Construction supervision a crucial element practices, which provide blood circulation project operations by directing labour. Accordingly, this study aims quantify impacts e...

Construction projects are characterized by their dynamic nature and operational details. This paper presents a hybrid simulation methodology; designed to model construction projects. The methodology utilizes Discrete Event Simulation (DES) and System Dynamics (SD). DES has been widely used in modeling construction operations; however, it lacks the ability to model the global aspects of operatio...

Field construction can be planned, monitored, and controlled at two distinct levels: 1) the activity or schedule level; and 2) the operation or process level. Graphical 3D visualization can serve as an effective communication method at both levels. Several research efforts in visualizing construction are rooted in scheduling. They typically involve linking activity-based construction schedules ...

In this paper, we give a state review of modeling methodologies for four-dimensional computer-aided design (4D CAD) and three-dimensional (3D) animation of operations simulation. We then present our efforts of integrating 4D CAD and 3D animation of operations simulation to facilitate the construction planning of the main stadium for the Beijing 2008 Olympic Games (nicknamed the ‘‘Bird’s Nest’’)...

Discrete-Event Simulation is an event-driven simulation in which a real dynamic process is imitated as it progresses over time. It has been recognized as a powerful technique for the quantitative analysis of complex construction operations. The two main DES strategies for modelling construction operations are Process Interaction (PI) and Activity Scanning (AS). Although each strategy has its ow...
