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.

Plan

The above illustration is for External underground service duct systems from the NBS section Trench and duct systems for buried services. This is indicative of the LOD requirements for External underground service duct systems.

Requirement

Visual information to provide fixed principles of the design supporting procurement. Developed coordination between all professions. Visual representations showing coordination for general size and relationships between different elements of the construction. Graphical representation of system, dimensionally accurate indicating primary performance characteristics. Graphical information represented may alter dependant on visual information to be produced, eg: Scope of work drawings, setting out, floor loading etc Typical / Installation details separately produced linked to model element and adjacent constructions.

Purpose of information

To provide a visual representation of proposals at a Technical Design stage supporting full spatial coordination.

Requirement

Visual information to provide full information to support construction / installation. Developed coordination between all professions. Visual representations showing final coordination for size and relationships between different elements of the construction. Graphical representation of system, dimensionally accurate indicating primary performance characteristics and sufficient information to support installation. Typical / Installation details separately produced linked to model element and adjacent constructions.

Purpose of information

To be updated during the construction process to reflect the final design, and to provide a future reference to sit alongside the O&M Manuals.
