shop drawings standard procedures 1

[jrk7490]

Can anyone help me with a document listing the team player responsibilities of owner, architect, GC, Contractor and subcontractor? I am particularly interested on what is offered to produce shop drawings and who's responsibity it is to submit the required information.

Specific requirements are typically listed in the Division 1 sections of the project specifications, usually handled by the architect or construction manager. The requirements will vary from project to project.

Ideally, the (sub)contractor submits shop drawings to the GC or Construction Manager or Architect or Owner (whoever is contractually obligated to be the liason between the construction team and the design team. This entity then transmits the shop drawing to the design team (architect and/or engineer) who reviews it and comments/approves/rejects and returns the shop drawing submittal back up the chain.

Shop drawings can vary from copies taken from catalogs to actual product samples. Ideally, they should include project specific information pertaining to what is actually being submitted for review.

Thank you PEDARRIN2. What I am looking for is a summary of who is responsible for what. I have seen somewhere, I believe its an AIA standard or requirement on what is included in the project package to successfully prepare shop drawings and who's responsibility it is to provide them. I am doing underground drainage shop drawings and I am being asked to size the housetrap pits (5 in all) but the project specs do not coincided with the code, engineers drawings or anything for that matter. I need to know whos responsible for what regarding the design, code conflicts, and layout conflicts with other piping, footings, etc.

The engineer is responsible for designing per code. So, if you are on the contractor side, you would not be responsible for code conflicts. Past that, "responsibility" is a nebulous term which can vary widely, based upon the type of project involved and how the specifications are written.

AIA guidelines are just that. The drawings and specifications are the contract documents which are binding for the project.

If the engineer is providing installation drawings, then he is responsible for designing a system that coordinates with all other trades. Generally, the engineer does all that, but since he is not providing installation drawings, there might be some issues.

In my experience, the engineer is not providing installation drawings but a "general design intent" which may be very exact or may be very general.

In the specs I use, there are clauses that the intalling contractors are responsible for specific installation layout and coordination with other trades.

The installing contractors are responsible for providing coordination drawings which are typically signed off by all the trades indicating pipe/duct/conduit elevations and distances from column lines.

The engineer typically reviews them, makes comments, but may not have to approve them.

If something doesn't fit or cannot be shifted a few feet to miss structure or other trades, then the engineer is typically brought in to assist the coordination.
