Most of the materials and components for a construction project are lifted by cranes. Much research has been done for path planning, motion control, and online navigation to reduce conflicts and improve efficiency. This paper proposes a new simulation approach based on agents to coordinate crane operations where two cranes are working together. Agents can dynamically control the kinematic action of the two cranes respecting the functional constraints for safety and efficiency of operations. A simulation model is under development using a case study to investigate the feasibility of the proposed approach.
