We are an employer using the ECC and the works information states that our contractor is to design the works. During the tender period, the contractor submitted an outline tender design and we later entered into a contract. Nothing was said about the design submitted. If it is subsequently identified during the detail design stage that part of the contractor’s design is not in accordance with the works information, could it be deemed that the design is not acceptable as it does not comply with the contract? Or, as we went into contact with that outline design, do we have to accept the error?
