Outline specification

Specifications are written documents that describe the materials and workmanship required for a development. They do not include cost, quantity or drawn information but need to be read alongside other contract documentation such as quantities, schedules and drawings.

Written information about materials and workmanship should not appear on drawings or in bills of quantities as this can result in contradictory specifications and can cause considerable confusion, instead they should refer to the appropriate clauses in the specification.

Specifications should be developed iteratively alongside the design, and not left until the preparation of production information.

An outline specification is a brief description of the main components to be used in construction. They should be described in sufficient detail to allow the cost consultant to prepare some approximate quantities.
