The NSCS covers requirements for the construction of concrete building structures of in-situ concrete, precast concrete and hybrid concrete systems. It is especially relevant for structures designed to BS8110 and EN1992 (EC2).
Edition 4 which has been fully revised to meet the requirement of BS EN 13670 Execution of concrete structures use of which is required for execution of BS EN 1992 and other Eurocode designs.
This edition of the NSCS specification has been prepared for use with Eurocodes and has been co-ordinated with the standard for execution BS EN 13670. It assumes in clause P1.2.1 that design has been carried out in accordance with the Eurocodes.
It is very strongly recommended that the NSCS Third Edition be used for projects designed to other codes. If this edition is to be used with design carried out to another code – for example BS8110 this must then be stated in both clauses P1.2.1 and P 1.6.
A key intention of the NSCS is that its use simplifies both the production of a project specification and the understanding of that document by the Constructor who is going to carry out the work. That is why the document text cannot be altered and the document layout and format has been fixed so that any project changes can easily be identified when reviewing the specification during the tender process. Clauses P1.13 and P2.9 will expand and allow the addition of any amount of extra information required for a project.
The NSCS contains three documents:
- The National Structural Concrete Specification (NSCS) Document
- The NSCS Project Specification Template
- The NSCS Project Specification User Notes
