Requirement

Graphical representation of element, dimensionally inaccurate.

Purpose of information

To provide a visual indication of proposals at a Concept stage identifying key requirements such as access and maintenance zones etc. Information to be suitable for zonal spatial coordination of primary systems / elements.

Requirement

Visual information to provide developed principles of the design to a greater level of detail. Developed coordination between all professions. Visual development showing coordination for general size and primary relationships between different elements of the construction. Can form a brief for a specialist sub-contractor or fabricator to progress with their technical design, fabrication and installation. This would be expected to include critical dimensional coordination, performance requirements and qualities of finish.

Purpose of information

To provide a visual representation of proposals, confirming brief for technical Design stage supporting full spatial coordination.
