Once contractors and other relevant professionals have been appointed and designs are sufficiently advanced, work may commence on the project site. Typically, a construction site will include a secure perimeter to restrict unauthorised access, site access control points, office and welfare accommodation for personnel from the main contractor and other firms involved in the project team, and storage areas for materials, machinery and equipment. This Database was designed to perform Site Development Works Cost Estimates, based on generic cost curves for several Activity families types generated using benchmarking techniques. The benchmarked curves give Work Performance as a function of a capacity variable or combination of variables. The cost curves and other information contained in this application can be used to develop the overall construction capital cost.
