Supplies an outline procedure for the preparation of design briefs for the building services components of buildings. The procedure is intended for use by building services designers, but will be of interest to client organisations. The procedure is divided into four stages - inception, feasibility, outline proposals and scheme design. For each stage identifies the key activities involved in briefing, and highlights the main considerations the designer should take into account. The procedure incorporates report stages which are used to provide documentation of the decisions made and the conclusions of the design studies. Provides aids to some of the main data-gathering activities in the form of checklists, included as appendices.
