3. The contractual arrangements used by clients to procure a building can have important consequences for the reliability of the design and the adequacy of the construction. Frequently, building design procurement will involve the appointment of a number of designers who may be employed by more than one organisation.

In these circumstances the client should appoint a lead designer or other appropriately experienced and qualified person to oversee the design process.
