Looks like an attempt to turn an NEC contract into a JCT contract !!
Whereas JCT, certainly the D&B form, has Employer's Requirements, Contractor's Proposals, Contract Particulars, Schedules etc, the scope of what is required under an NEC contract should be defined within the Works Information (NEC3 ECS).
The associated documents under an NEC contract, such as Site Information and Contract Data Parts 1 and 2, facilitate the administration of the contract procedures and should not actually define the scope of works (notwithstanding Site Information and clause 60.1 (12)).
Consequently it is unlikely that it will make any difference, unless there are particular requirements stated in a document other than the Works Information, which may give rise to a Defect.
