Re: Steel shop drawing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
A more basic commentary to this discussion, at least in my experience, is
that the main goal of any shop drawing is for the fabricator/supplier to
communicate with the engineer/architect their interpretation of the
construction drawings. This is also an opportunity to clarify or request
information in regards to the original drawings such as certain dimensions,
welds, bolts, etc. It really is a supplement to the permit CDs, and on
smaller projects may not be required. In my experience, this is
communication between the contractor and the design professional, and the
building department may not even be involved at all in the shop drawing
process, unless those documents were signed and sealed and considered part
of the construction documents (pre-engineered trusses come to mind).

Daryl and Neil have given you lots of good advice, depending on what your
exact role is in all of this. I would be calling the architect and/or owner
and following this up in writing. Getting the building department involved
should be your last resort if you think the contractor is unwilling to make
the corrections and will just cover it up.
