• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Before you order carcassing timber

Cut ends

Treat any cut ends with a suitable end-grain preservative, especially on external work.

Which treatment?

Treatment is specified by use class. Timber inside a building is usually use class 1 or 2; external timber out of ground contact is use class 3; timber in ground contact needs use class 4.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Quantities: a worked example

A floor 4.8 m wide with joists spanning 4.2 m at 400 mm centres needs 13 joists, plus trimmers and noggins. The section and grade, such as 47 × 200 mm C24, come from span tables or your engineer; send us the timber schedule and we will price it.
