Requirements. The Public Sector Supplement 2011 also added to the definition of
Contract Documents any agreed Building Information Modelling (BIM) protocol.

SBC/DB, see Sections 5.2.3 and 5.3.4.
As the work proceeds, the contract allows the Architect to issue instructions and
the Contractor has an obligation, under clause 3.10, to comply with all instructions
issued to him in regard to any matter over which the Architect has power under the
contract to issue instructions. The instruction may be one which requires a Variation
as defined in clause 5.1. Variations are considered above in Section 4.5 and the proce-
dures to be followed in respect of the valuation of Variations are set out in more detail
in Section 8.2.3.
The Architect may, in terms of clause 5.3.1, in his instruction for a Variation, state
that the Contractor is to provide a 'Variation Quotation'. This is a reference to the
procedure set out in Schedule Part 2 for submission by the Contractor of a quotation
setting out the amount of the adjustment to the Contract Sum, including the effect of
the instruction on other work supported by all necessary calculations, any adjustment
to the time required for completion of the Works and/or Section to the extent that this
is not covered by any revision to the Completion Date already made, the amount to
be paid in lieu of any ascertainment under clause 4.23 or 5.3.3 of direct loss and/or
expense not already included elsewhere, a fair and reasonable amount in respect of the
cost of preparing the Quotation, indicative information on any additional resources
required to carry out the Variation and the method of carrying it out and, where appli-
cable, the base date for the application of Fluctuations Provisions. he Quotation is to
be sufficiently detailed to allow it to be evaluated by or for the Employer.
This procedure is time-consuming and requires significant input from both the
Architect, in terms of detailing the proposed Variation, and the Contractor in
preparing the Quotation. It is therefore likely to be used only for the most significant
proposed Variations.

sufficient information to allow him to do so, whichever is later. The Quotation is to
