Quote ="TrentBarrett"You have proved my point the design and build procurement method shifts total responsibility to the main contractor Barr in this case for the construction and design of the stadium. I presume Barr use their own design team to produce and over see the design and therefore they are still required as acting architects to authorize the Practical Completion Certificate and hand possession of the stadium to Saints. If this incident happened prior to completion this certificate wouldn't have been granted. '"
Again not true. Barr would not self-certify completion. As I said it would be done by the Employer's Agent who are engaged by the Employer.
Without seeing the specific terms of their contract we do not know what Barr's design responsibility is. JCT standard form only requires the contractor to "complete" the design so if the roof was already designed it may not be their responsibility.
