AJ Specification: Timber Costs

Don’t look like a plank when pricing woodwork. Here, Neil Barnett, resource cost services manager of BCIS, the Building Cost Information Service of the RICS, provides the latest sample cost breakdowns for timber structural members, first- and second-fix elements.

These guides reflect the expected prices for a medium-sized residential project for products in the low to uppermiddle specification range. Prices do not include contractor’s preliminaries, overhead and profit margin. The base date is April 2010 at UK mean location and prices are based on the BCIS Online Rates Database (www.bcis.co.uk/ordb).
