RE: Tilt-Up Wall Submittal Review

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I think that if you do not return a submittal in a timely fashion with a stamp or letter saying “Rejected” or “Returned without Review” then your action or inaction may be interpreted as “Approval” by the contractor. Even language stating that you have reviewed the submittal and have no objections is the same as “Approval” according to the engineering publications and case studies I have read.


Approving a submittal does not necessarily mean that you designed the system depicted; it does not mean that you are responsible for the system depicted; it does not mean that there are no errors in the submittal. Approval means that you have reviewed the submittal as it relates to your contractual responsibilities and your construction documents and that the submittal does not conflict with your design criteria. It is probably a good idea to clarify that your approval does not relieve the contractor of their responsibilities for means, methods, coordination, code compliance, job-site safety, etc. It is also a good idea to require that the contractor review and approve the submittals prior to forwarding them to you for your approval.

Subject: Tilt-Up Wall Submittal Review


I received a large package of information for a tilt-up wall building I designed.  The submittal was produced by Dayton Superior.  It includes a lot of general information on tilt wall erection and then the insert and bracing details for the wall panels.  I wondering how a submittal like this is typically handled by other engineers.  This is basically a “means and method of construction” submittal.   I didn’t design the lifting procedure, sequence, anchors, bracing, etc. 


I don’t think I should “approve” it.  I don’t think I should put a typical shop drawing stamp on it.  I’m considering sending it back with a letter stating I looked at it, I don’t take exception to anything and remind the contractor that they are responsible for means and methods of construction and I take no responsibility for the lifting and placing design.


Is that how others handle it, or is should I look at this differently?
