Abstract :
Modern construction operations involve many different resources such as labor, equipment, and materials. The interactions among these resources can be realistically modeled and analyzed using discrete-event simulation. During construction planning, it is necessary to model and simulate construction operations and develop a work plan that minimizes idleness, eliminates bottlenecks, increases productivity, and reduces costs. Among the various applications in the construction industry, discrete-event simulation has been successfully used in modeling the construction of precast-concrete parking structures. The paper presents the application of discrete-event simulation to model and analyze the erection process of a precast concrete parking structure. Simulation is conducted by using a graphical discrete-event simulation system named COOPS. Construction equipment, labor, concrete members, erection times, and operating strategy are modeled and simulated to investigate the productivity, resource utilization, and unit costs
