This standard has been written by a group of independent industry leaders. The International Construction Measurement Standards Coalition (ICMSC) is a growing group of more than 40 professional and not-for-profit organisations from around the world, working together to develop and implement international standards for benchmarking, measuring and reporting construction project cost.

About the coalition

The Standards Setting Committee comprises of 27 independent experts, from 17 different countries. They were appointed by the coalition to draft, consult and produce the new International Construction Measurement Standards which can be downloaded below.

ICMS Explained

ICMS Explained, a user guide for the below International Construction Measurement Standards, is a technical document that sets out the purpose, context and philosophy of ICMS. This practical resource will equip quantity surveyors and cost consultants to deliver cost estimates and financial reports in line with ICMS.

Practitioners will find the below guide valuable as a reference document to address questions of the terminology used and how ICMS rules could apply to a specific project situation.

The user guide also sets out how ICMS is used in practice by drawing on and illustrating real examples of where it is already in use.

  • ICMS User Guide: Intended for use by RICS and other relevant professionals to apply the standards. The guide provides the background, structure, content and potential use for ICMS, together with various appendices, which provide further and more detailed guidance and worked examples.
  • Appendix A Mapping to NRM 1: This excel document maps across the NRM 1 cost groups to those which are now presented in ICMS, such that a valid interface can be achieved when comparing historic cost classification data. A PDF version of Appendix A is included in the ICMS User Guide.
  • Appendix B Worked Examples: A selection of ‘live’ projects where the presentation of the cost classification data is illustrated in a form that aligns with ICMS, and adjusted as necessary to suit local circumstances. Worked Examples include examples of projects from Turkey, Australia, and Malaysia. A PDF version of Appendix B is included in the ICMS User Guide. 
  • ICMS Linked Excel Templates: This blank template allows practitioners to complete a cost report in accordance with the standard and with the Excel sheet formulae already embedded within.
