Specification and Scheduling

Small building projects such as house extensions frequently go over budget because of misunderstandings about the scope of work, the quality of workmanship and the materials to be used.

A good specification makes everything clear from the outset, so the price quoted for doing the job is much more likely to be the price you end up paying!

Specification is an essential part of the design process.

If a specification is written badly it can cause major problems for every member of the construction team, and can cost the client a great deal of money. If the specification is well written it can enhance project delivery for the whole construction team while saving everyone money.

A specification is:

  • a tool for conveying the required quality of products (both fabric and services) and their installation for a particular project; and
  • a means of drawing together all the relevant information and standards that apply to the work to be constructed.


The need for forward planning in any project is essential. The more thought put into the organising the sequence of operations even on a small house extension, the more smoothly and efficiently will the project run.
