Complete this electronic spreadsheet to ensure that your Lead sheet fully supported roof covering systems 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
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 spatial coordination of primary systems / elements.
The above illustrations are for Aluminium sheet fully supported roof covering systems from the NBS section Metal sheet fully supported roof covering systems. This is indicative of the LOD requirements for Lead sheet fully supported roof covering systems.
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.
