The Principles of Measurement (International) for Works of Construction, published by the Royal Institution of Chartered Surveyors, provides a global framework for the measurement and quantification of construction works.

This guide establishes the core principles that underpin consistent measurement across different regions, sectors, and project types. It is designed to support international construction projects where varying local standards can create challenges in cost comparison and reporting.

The publication focuses on standardising how quantities are defined, measured, and described, enabling greater transparency and consistency in estimating, tendering, and cost management. It is particularly valuable for organisations operating across multiple geographies, helping to align practices and improve communication between stakeholders.

As construction becomes increasingly global and data driven, the Principles of Measurement (International) guide plays a key role in supporting harmonised approaches to estimating and measurement.
