Having received a significant addendum whilst tendering, should that have been included within the Contract Documents? We have a separate estimating/bidding team, and they had incorrectly filed the addendum so we (the site team) have only just realised that it even exists!
Obviously, there are questions to be raised with regard to our tendering procedure but how do we stand contractually? There is no documentation within the contract we have been awarded referring to any addenda at all. The addendum increased the specification of some items but apparently we haven’t priced them as such. The WI has recently been updated to reflect the change in specification so we notified it as a CE, only to be told that it actually wasn’t a change at all.
