Modelling Requirements

General

BIM is used for all building systems design, development and analysis, including but not limited to architectural, structural, mechanical, electrical, plumbing, and fire suppression, etc. During Conceptual Design, Schematic Design and Design Development Phases, BIM technology is used to develop and establish building performance and the basis of design in accordance with the client’s standards. The model… read more »

Types of model elements

Model elements are derived from the following sources: Manufacturer’s Model Elements Elements created by and acquired from manufacturers often have more information than is prudent to keep in the BIM model; the appropriate level of detail should be retained for the design element. However, embedded performance data remains for analysis and specification purposes. Custom Created Model… read more »

Model geographical location

The spatial coordination (coordinates) of the master BIM file is set at the beginning of the project. Once established, spatial coordinates should only be changed by mutual consent of the team and the Client’s Project Manager, with the matter recorded in the meeting minutes and the BMP. Once the design coordinate system is agreed upon, any model(s)… read more »

Points of reference

The BIM Manager provides a 3D grid for incorporation into the spatial coordination model. This provides the viewer with a quick point of reference when navigating through the model. Room information is also incorporated. Coordinates and units The coordination base of the project should ensure that the entire modelling area is on the positive side of… read more »

Requirements for modelling space

The method of measurement for floor area adopted for the project is the defining kernel of space counting procedures for the client and form the basis for the Program for Design (PFD.) The method of measurement for floor area is defined before modelling begins. Space information imported from the Architectural Programming Software PFD export is the source for… read more »

Publishing of Models & Meta Data

At the official release points of the project, such as building permit application and construction cost estimation, the BIMmodel and the documents that are produced from it are important tools for decision making. In a pure BIM-based design process, the BIM models and design cannot be separated and therefore they should be publishable at the… read more »

Space naming and coding

Each space includes the following attributes, to be maintained throughout the Design and Construction BIM models. Building ID number. Wing (where applicable.) Floor (Level.) Department (where applicable.) Sub-department (where applicable.) Space name – English name and abbreviation. Room number – Wayfinding room number. Room number – Construction document number (where applicable. Used on large complex projects… read more »

Equipment coding

Each individual piece of equipment including mechanical equipment includes the following attributes and is maintained throughout the Design and Construction BIM models: Item name – English name and abbreviation. Item code – Equipment ID number. Unique item number – GUID. Item type (by function) – Construction Information Classification System. Item tracking number – Stock identification number (where… read more »

Additional modelling standards

In the absence of existing documented modelling standards mandated by the client, the BIM Team nominates the BIM Modelling Standards to be used on the project. Any amendments considered necessary must be documented. When the BIM Modelling Standards and amendments have been agreed by the BIM Team they are adopted and managed for consistent application… read more »

Final BIM deliverables

General One of the primary benefits of the BIM model for the client is to use it for facilities management upon occupancy. Information that matures during the construction process is captured in the appropriate models on an on- Globally Unique Identifier (GUID.) GUIDs must be preserved through generation and regeneration of IFC deliverables so that a… read more »
