Space is one of the resources that may cause crucial problems during construction. Discrete event simulation has been widely used in construction to allocate resources and improve productivity or mitigate conflicts. However, simulation research that provides an explicit method to investigate possible space conflicts is still limited. This paper suggests a(More)

The decision-making process is a very essential part of any construction operation. Simulation can be used as a tool to assist construction managers in making informed decisions. In this paper, simulation is applied to a Concrete Batch Plant to analyze alternative solutions and resource management. Data is collected to define activity durations for the(More)
Assessing productivity, cost, and delays are essential to manage any construction operation, particularly the concrete batch plant operation (CBP). This paper focuses on assessing the abovementioned items for CBP operations using stochastic mathematical models. It aims at (1) identifying the potential sources of delay in concrete batch plant operation; (2)(More)
In port container terminals, reducing vessel turnaround time improves the terminal productivity and increases the capacity of world trades across the globe. This time reduction can be achieved by improving one or more container terminal major resources. Much research has been done on improving container terminal efficiency as a means to reduce vessel(More)
The installation of pile foundations is complicated by an enormous number of problems. They include unseen sub-surface obstacles, lack of contractor experience, and site planning. These major problems and other minor ones make it difficult for the estimator to evaluate the piling project productivity and cost. Therefore, this study is designed to assess(More)

Despite the fact that applying constructability concepts in building designs have led to savings estimated within a range of 1% to 14% of the capital cost, the construction industry still lacks an advanced tool to assess and check for constructability implementations in designs. Therefore, the objective of this research is to propose a quantitative(More)
