Ensuring quality BIM models

Learn how to create quality BIM models with clear specifications, structured data, and standardised processes for accurate, efficient project delivery.

Last updated 23 March 2026

Building Information Modelling (BIM) is a digital process that creates highly detailed 3D models. The technology does this by capturing both the physical and functional features of a building or structure. Unlike traditional 2D drawings, BIM can include vital information about the building across its lifecycle, from initial planning and design to construction and operations.

Optimising project delivery via quality BIM models

Using quality BIM models help improve project visualisation, coordination, and information management. This enables project stakeholders to collaborate more efficiently, enhancing overall project delivery.

To fully realise these outcomes, structured and standardised information management is essential. This includes clear specifications for model content, levels of detail, and data formats. These enable consistent data quality, support data analytics for informed decision-making, and facilitate efficient data exchange across the project lifecycle

Without this, projects face fragmented data, miscommunication, inconsistent outputs, uninformed decision-making, and costly rework. This can ultimately undermine the intended benefits of BIM.  

How to create quality BIM Models

Project teams can use the resources below to create and deliver quality BIM models throughout various project phases. 

(a) CORENET X Code of Practice

The CORENET X Code of Practice guides industry practitioners in preparing multi-agency regulatory submissions across the key submission gateways in CORENET X. It provides recommended procedures and good practices to address common BIM issues, from general project collaboration to specific details that vary from firm to firm today.

(b) Model Content Requirements

Model Content Requirements (MCR) specifies the standard information and data deliverables needed for BIM at each project stage and for different building types.

(c) BIM Handover Technical Guide and Sample Clauses

The BIM Handover Technical Guide and Sample Clauses defines the required BIM model content and 2D drawings for construction tender documentation, whilst offering comprehensive guidelines for BIM preparation and issuance. The resource also includes sample BIM handover clauses to support implementation.
