BIM-MEPAUS Models

BIM-MEPAUS Generic Design and manufacturers content has been developed to support integrated project workflows and the needs of designers, manufacturers and installers, as well as owners.

BIM-MEPAUS develop both Generic Design and Manufacturer’s content. Plant, equipment and fitting content is built to BIM-MEPAUS Modelling Guidelines with regard to family naming convention, geometry, hosting and connector requirements. BIM-MEPAUS check the content is compatible and functional within the Template Add-In prior to issue.

Plant, Equipment and Fitting model content comprises of LOD 300 Generic Design Models and LOD 400/500 Fabrication and Manufacturer’s Certified Models (MCMs).

Generic Design Models provide for designer’s requirements for design scheduling up to and including LOD 300. These models have the BIM-MEPAUS defined shared parameters added for design, tagging and specification purposes.

Each generic family incorporates geometry based on representative manufacturer data and provides a range of sizes that are intended to meet LOD 300 modelling purposes.

MCMs allow suppliers to deliver project specific LOD 400 content inclusive of the technical schedules needed for finalisation of the commissioned as built LOD 500 model.

The benefits of the BIM-MEPAUS approach to content development include:

  • A single reference model that captures best practice with respect to content design and functionality;
  • Interoperability between generic and manufacturer’s content through the use of content; and
  • Reliable scheduling through the integration of the Master Reference Shared Parameter Schedule.

Registered BIM-MEPAUS Subscribers can locate Generic Design models and MCMs through the BIM-MEPAUS website links below.

BIM-MEPAUS Generic Design Content

BIM-MEPAUS Generic Design Content is created by adding the LOD 300 shared parameter schedules to the geometry. Once created this generic design content is placed on the BIM-MEPAUS  website so that it can be downloaded by subscribers.

The Generic Design Content provides a number of family types providing a representative range of sizes that are adequate for LOD 300 layout and scheduling purposes.

Prior to use on projects, it is expected that design firms will populate the families with their own, additional standard quality specification parameters to reduce the number of fields that need to be completed by the engineer or modeller each time a component is added to the model. Design firms may choose to use the BIM-MEPAUS Generic Design content without adding additional parameters if suitable to their organisation and project needs.

Manufacturer Certified Model Content

There are a number of methods that are available for creating Manufacturer’s Certified Models with the choice determined largely by the type of component; plant, equipment or fitting.

Key points in relation to Manufacturer’s Certified Models include:

  • They replace Manufacturer’s certified drawings and technical schedules;
  • Manufacturer’s Certified Models provide the geometry and technical data for the component to be supplied;
  • All BIM-MEPAUS  Manufacturer’s Certified Model content is sourced and/or tested for compliance against the relevant BIM-MEPAUS standards and specifications and interchangeable with BIM-MEPAUS  Generic Design Content.

Fittings

Fittings are normally used to complete a system installation and are typically selected and downloaded from the BIM-MEPAUS website but may also be provided through a Manufacturer’s website. There is typically no requirement to modify the shared parameter file values for the component.

Equipment

Equipment is individually designated with a component ID and is normally selected from a standard product Family which includes a range of types covering a range of capacities. Examples of equipment include VAV terminals.

Plant

Plant is selected and manufactured to meet a specific set project requirement. Plant includes items such as chillers, pumps and fans. The delivery of Manufacturer’s Content based on, and interchangeable with BIM-MEPAUS  Generic Design Content will be principally through the BIM-MEPAUS website or Manufacturer’s websites incorporating content configurators.
