Level of information

Complete this electronic spreadsheet to ensure that your Air handling units product information meets the requirements of Level 2 BIM. This is important as it will enable your customers to select, specify and use your products within the BIM environment. Once you have completed this template you can host it on your own website or distribute it to your customers. Please note that we do not host completed product data templates within the BIM Toolkit.

Requirement

Visual information to provide general principles of the design. Showing arrangement of system with their relationship to internal and external context, and key project criteria to suit a clients brief. General descriptions would be expected to communicate principles of materiality, scope, colour and context. Expect strategic coordination with other professions to show general principles of the design.

Purpose of information

To provide a visual representation of proposals at a Concept stage and support general spatial coordination.

Air handling units

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.

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.
