Why, we all know that architect always change dimension before we even notice it. Just have to update our drawings every so often. I don't see any choice. I also incorporate a note in my General note requiring the contractor to coordinate dimensions in all drawings and bring to my attention of any discrepencies before proceeding to construction. That's my back-up insurance in case I miss something. I understand your position (and the position of a large part of the list server), but I can't agree with it. Please don't take this personal, I only singled out your letter because it made some comments I think lots of people agree with, so nothing personal here. As the design professional, we are responsible for coordinating our dimensions. We should not put this responsibility on the contractor. If there are discrepancies between the structural drawings and the architectural drawings it is a breakdown in communication and coordination between the architect and the engineer and it is not up to the contractor to straighten us out!! I prefer to include all dimensions on my drawing that are important to the structure and the design. I want everyone who looks at my drawings to know what I designed it for. If my dimensions do not match the architects drawings and the contractor points that out then I do one of two things; 1. I go back to the Architect and the Owner and apologize for having poor drawings and tell them I will do whatever I need to to straighten them out. 2. I chew out the architect for changing the dimensions and not telling me. It is his responsibility to coordinate any changes he makes with the consultants. If the architect changes dimensions and as a result my design is insufficient because the span was enlarged, shear increased, etc. and a structural failure begins to occur, I can point back to my drawing and say "Hey, it was not designed for that. Here is the dimension it was designed for". If I never included the dimension on the plan and the architect changed it then how is anybody to know that the design was inadequate? And how can I justify, in court if need be, that I designed it correctly? I realize this is an ideal world situation where the architect and the consultants fully coordinate their drawings. But isn't that what the Owner is paying for? Do we write clauses in our contracts that state coordination of all dimensions is the Owners and Contractors responsibility? NO! Therefore lets do the job we are paid to due. If an architect continually makes changes on you without telling you then write it in to your contract about extra service billing for making these changes. If he still does it then maybe you shouldn't be working for him because they are a disaster waiting to happen! The hardest thing is to turn down work, but if working for them compromises your integrity as an engineer then maybe you should not be working for them.
