12 April 2014

Employers usually require something done by a certain date. How can this be done using the NEC3 Engineering and Construction Contract (ECC) or the NEC3 Professional Services Contract (PSC)?

Who wrote this?

Standing Committee on Structural Safety (SCOSS).

SCOSS is an independent body established in 1976 to review building and civil engineering matters that affect the safety of structures. The sponsoring bodies are ICE, Institution of Structural Engineers and the Health and Safety Executive.


It was first published in July 2009.


The Structural Eurocodes became mandatory in 2010. For most engineers they will represent a major change to the manner in which design is implemented.

Since 2010, engineers need to comply with the Eurocodes, so SCOSS produced this summary to draw attention to the assumptions underpinning them.

Who should read this?

Anyone who is new to dealing with Eurocodes and needs some background.


This 4-page booklet considers the assumptions relating to the structural Eurocodes which are given in BS EN 1990. It covers Eurocode requirements and the six assumptions behind Clause 1.3.
