The problem is that most historical information on project duration available to clients and consultants has been based on the time period stated in the contract and not on the actual time the project took to build. In other words, from the day work started on site to the date of practical completion when the building is handed over with only minor defects.
Now the RICS' Building Cost Information Service has produced a guide on the actual time taken to construct a building based on its cost and a few key project variables, such as procurement route, client type, project sector, building function and region (all of these are listed in the table opposite). To keep things simple, the guide includes a CD, which allows users to predict the likely construction time for their building.
