Chapter 6: Effective Specification

The importance of specifications and how they should always be developed for a ground investigation is discussed in this section. In order to promote best practice, the UK specification for ground investigation is championed as the best method of achieving a suitable and sufficient ground investigation.

Emphasis is placed on the specifier having appropriate knowledge and experience, so that when the specification is written, it will not only cover all of the anticipated works, but also link seamlessly with the Bill of Quantities which provide the mechanism for measuring the work undertaken. This section explains the typical specification coverage and the importance of collaboration, transparency and providing sufficient detail to allow the ground investigation specialists to establish appropriate costs.

Examples of a poor and well specified Bill of Quantities in relation to a ground investigation is given with discussion around this subject.
