I am after some advice please, we have been engaged in an NEC contract as a sub contractor where we designed a building to the clients works information. The design GA and elevations were agreed and accepted by the client. Now the client and us have noticed that an element of the building i.e window is not ideal as such and needs alterations made to it. where does the liability lay, with us as we designed it or with the client as they accepted our design as it was? We believe the building is fit for purpose and albeit we need to make a slight amendment to a high level window.
Any advise would be great.
