The document discusses cost management for real estate development projects. It addresses the why (reasons for cost management), what (procedures for cost monitoring), and how (methods used) at different project stages. Specifically, it describes using a cost model at feasibility stage, cost plans at design stages, and a priced bill of quantities at tender stage to monitor costs. It emphasizes verifying cost predictions at each stage and discussing significant differences with the designer and developer. Maintaining an up-to-date cost database is also important for accurate cost estimations throughout the extended project timelines.
