In this article the NEC is referred to generally and references are also made to the following two contracts from within the NEC suite: the Engineering and Construction Contract (“ECC”) and the Professional Services Contract (“PSC”)
Five key errors are made either singly or more often together when NEC document packages are collated.
• Incorrect use of the main pricing options • Misunderstanding the role of the Works Information, Site Information and Contract Data • Structuring amendments to the core and optional clauses incorrectly • Inconsistent language and drafting style to the NEC • Incorrect incorporation of specification

The document used to describe the works is the Works Information under the ECC. Consultants new to the NEC approach sometimes simply group the services they are to provide under Option A of the PSC as set out in the RIBA Plan of Work Stages with each stage representing an activity. Unless corrected this could have a hugely adverse impact on the consultant’s cash flow as some RIBA Work Stages take many months to complete on sizeable projects.
Confusion also arises when parties confuse the use of the activity schedule in Option C (Target contract with activity schedule) with its use under Option A. In Option C the Contractor is paid the Defined Cost plus the agreed Fee. In this Option the activity schedule is used to assess compensation events and as a management tool.
Misunderstanding the role of the Works Information and Site Information
The ECC Works Information Guidance is a good place to start to understand the different purposes of the Works Information, Site Information and Contract Data and the relationship between them. The information to be set out in the Works Information is defined in the ECC as information “which either
