Computer Simulation of Concrete Slab-on-Grade Construction

This paper presents a decision support system for contractors specialized in concrete floor finishing, making optimal use of available technology in automation. The paper presents a computer simulation model for concrete slab-on-grade construction considering different levels of automation that integrate conventional manual, semi- automated, and robotic work processes. The data used in the simulation was obtained through a survey of Montreal area ready-mix concrete plants, structured interviews with contractors, and site visits. The computer model is developed to assist those speciality contractors in selecting the most effective level of automation for their respective work environments and in visualizing the impact of the production rate of each individual task on the completion time of the entire process.
