If we are asked to quote for supplying & installing new items that were not part of the original contract, can we offer a quotation rather than it be based on defined cost plus mark up? Also do we have to do the work or can we decline?
This is not additional work related to the items we have a contract for, these are new / additional items required due to site design changes. We will offer a quotation but do not wish to be forced to go down the defined cost plus mark up route. Also are we obliged to offer quotation or can we decline quoting.
