BCIS would like to thank Lumsdon Wood Partnership for providing the data and everyone who submits projects to be published online.

Cost analyses are available as part of the BCIS Online service.

BCIS regularly receives projects where the contract comprises buildings with different functions which are analysed as Complex Contracts within the BCIS database. Every effort is made to prepare a separate analysis for each building type and each analysis shows the total scope and cost of the contract, which will influence the pricing levels.

Each analysis is cross referenced to the other analyses in the contract, which allows BCIS to capture separate analyses, £/m² rates, and functional unit rates appropriate to each building, e.g. number of vehicle spaces. The functional unit rate is the total cost of the building excluding external works, with preliminaries apportioned by value and divided by the appropriate functional unit.

BCIS Online is an industry repository for building project costs analysed elementally. It provides clients, consultants and contractors secure online access to their project data. The analyses can be prepared from contract documents used in most procurement routes, for example:
