The value of BIM lies not just in its 3D visualisation but in the quality and reliability of the data it provides. Inaccurate models can lead to clashes, cost overruns, safety risks, and disputes between project stakeholders. Accuracy is therefore the cornerstone of BIM practice, ensuring that models reflect real-world conditions and provide a trustworthy foundation for construction and operations.

Globally, project teams are moving toward higher Levels of Development (LOD) and stricter quality assurance standards (e.g., ISO 19650), making model accuracy non-negotiable. In the South African context, where infrastructure investments are significant and public accountability is paramount, ensuring model precision is essential to avoid waste and deliver on performance promises.

This masterclass provides ACPM members and allied professionals with the tools and strategies to audit, validate, and enhance BIM model accuracy. By understanding common pitfalls and applying structured QA/QC processes, participants will learn how to deliver robust, clash-free models that support decision-making across all project phases.
