RE: Plan check submittals and shop drawings

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Requiring a manufacturer to have a structural engineer seal drawings is a
fairly common practice.  The theory is that the manufacturer and his
structural engineer are intimate with the product which may be proprietary
or may involve elements or practices that are unique to the manufacturer.

I have come across this resistance before.  The trick is to write the
specification to put the supplier in violation of his contract if he does
not provide sealed drawings and calcs.  Tack on a little note about bond
forfeiture for noncompliance, and you'll get your drawings sealed. It is not
much different than if he accepted the contract, and refused to provide the
trusses, warrantee or any other contractually required component.  

You need to be specific, however, requiring the manufacturer to provide the
sealed drawings and calcs.  Just saying that they need to be sealed, may
imply that the EOR is to seal the drawings.

As the EOR I would not seal manufacturer's drawings.  It won't insulate you
entirely from litigation, but it is a good fire wall.

Subject: Plan check submittals and shop drawings

I would like to get any opinion regarding the following circumstances.
We have a tilt-up building under construction in the county of Orange,
The county building department requires that all prefabricated and deferred

items be prepared and sealed by a California licensed engineer. The roof 
framing of this building consist of manufactured steel trusses and as part 
of the plan check correction we have added a general note to our plans
saying that
" Truss calculations and plans shall be designed and sealed by a California

licensed engineer."    
The truss manufacturer have submitted signed calculations but refuses to
the plan which consist of a single sheet of erection plan and copies of our
pertaining to trusses.
The plan checker says that all deferred submittals must be sealed.
My questions are these:
When approved truss shop drawings are submitted to the building department,

are they considered deferred submittal? UBC
How would you resolve this problem?
Do you think that it is O.K. or appropriate for the engineer of record to
seal the truss
shop drawings, even if the manufacturer gives permission to use their

I would appreciate your response.
