National Structural Concrete Specification (NSCS)

The National Structural Concrete Specification for Building Construction was developed by CONSTRUCT, MPA - Cement, and the Building Research Establishment (BRE) and aims to be the standard specification for concrete frames in the UK. The specification is designed to achieve increased efficiency through a definitive, simple, straightforward specification which removes unnecessary conditions and facilitates construction. It also provides guidance on tolerances and finishes.

The specification is divided into two parts. Part One identifies clauses for standard concrete construction. This ensures that all parties involved - clients, designers and frame contractors - fully understand the normal requirements of efficient concrete construction.

Part Two provides a project-specific section for the requirements for individual projects. This highlights 'by exception' the required amendments to the standard requirements as outlined in Part One.

There is also a section of guidance notes which forms a companion to Parts One and Two and outlines the philosophy of the specification and background to individual clauses.

All members of the project team can benefit from the NSCS:

• Designers will no longer have to develop their own specification from scratch.
• Specialist concrete contractors will be able to tender more effectively and have more freedom to innovate.
• Clients will benefit from increased savings and cost benefits.

Printed and PDF copies of the NSCS 3rd Edition are available from CONSTRUCT. 

4th Edition

The next edition of NSCS which references European standards, including Eurocode 2, is due to be printed in 2010.  It will be similar in format to BS EN 13670 - Execution of Concrete Structures.
