The essential and authoritative Code of Practice describing accurate, systematic and reliable estimating processes for construction projects.


Pricing and bidding for construction work is at the heart of every construction business, and in the minds of construction consultants’ poor bids lead to poor performance and nobody wins. New Code of Estimating Practice examines the processes of estimating and pricing, providing best practice guidelines for those involved in procuring and pricing construction works, both in the public and private sectors. It embodies principles that are applicable to any project regardless of size or complexity.

This authoritative guide has been completely rewritten to include much more contextual and educational material as well as the code of practice. It covers changes in estimating practice; the bidding process; the fundamentals in formulating a bid; the pre-qualification process; procurement options; contractual arrangements and legal issues; preliminaries; temporary works; cost estimating techniques; risk management; logistics; resource and production planning; computer-aided estimating; information and time planning; resource planning and pricing; preparation of an estimator’s report; bid assembly and adjudication; pre-production planning and processes; and site production.

  • Established standard for the construction industry, providing the only code of practice on construction estimating
  • Prepared under the auspices of the Chartered Institute of Building and endorsed by a range of other professional bodies
  • Completely rewritten since the 7th edition, to include much more contextual and educational material, as well as the core code of practice

New Code of Estimating Practice is an important book for construction contractors, specialist contractors, quantity surveyors/cost consultants, and for students of construction and quantity surveying.
