Acceleration
Published February 2024
Effective from February 2024
This practice information summarises what is meant by ‘acceleration’ in the construction
industry, how acceleration can be achieved in practice, and how it can be valued.
When used in connection with construction contracts, ‘acceleration’ generally refers to increasing the originally planned or current rate of progress of the work so as to complete the project (or, where the contract allows for the project to be completed in sections, a section of the project) earlier than would otherwise be the case.
This is part of RICS' Black Book, which is a collection of technical practice documents that covers all processes throughout the construction project life cycle. The documents are essential development tools for junior professionals working through their APC and useful guides to best practice for more experienced professionals.
A project is currently underway to review and update the Black Book content with the aim of producing a comprehensive new edition. Expected to publish in 2025, the new Black Book will comprise an overarching global professional standard, accompanied by practical guidance material.
