Ourselves (the client) have notified the D&B contractor of a CE 60.1 (change of works information) e.g: we have provided a brief scope, requesting for a range of additional works in a unit, more stud walls, mezzanine, m&e works. I understand and feel it is fair that the Contractor can provide a few assumptions before the design is progressed, as we have not provided detailed design.
Therefore once they submit the Compensation event (quotation), with assumptions clearly stated in the quote, of which we agree too, if the cost of the assumption is to change, I the Project Manager can correct/amend the CE e.g: the contractor and I assumed the m&e works would be £25k, but is actually £30k on completion, I can amend the CE correctly to £30k.
So I presume the contractor has a few options before submitting quote, don’t price the M&e, and treat as a separate CE later on or make an assumption alongside the Client PM?
Thank you
