Shop Drawings

[jike]

What procedures are recommended for:

1) stamping a date received

2) stamping a date reviewed

on shop drawings?

Does your company do every sheet, just the front sheet or just the transmittal? If just the transmittal, then I would think at a minimum that it should list every sheet and the date issued. If just the front sheet, does it have an index that lists all other sheets?

What are the implications for liability?

Jike,

We stamp only the transmittal with 'Received', but each drawing sheet is stamped with the review stamp. In this way, you can accept, reject, or request changes by sheet. Our review stamp has a place to put the received date as well as the reviewed date.

What I don't like is that we treat manufacturer's cut sheets the same, in effect accepting or rejecting each page of a brochure. I've never worked anywhere that stamped cut sheets in a similar fashion. Personally I think it's a liability.

Oh, we will also do a partial release (send some of the drawings back), especially if there is a significant problem. In my shop set I like to keep all versions of a shop drawing and mark them by turning the corner over that has the drawing number and putting the most recent drawing on top, approved or not. It's a good way to track submittal status.

We also date stamp the transmittal only and place the review stamp on each drawing. Our shop drawing log lists all drawings for a particular sumbittal; date received; reviewed by; date returned; disposition.

We don't review cut sheets on a page-by-page basis. It's all or nothing.

Regarding liability, we don't use "Approved" any longer. Unless a client request specific wording (except Approved) we use "Reviewed"; "Reviewed as Modified"; "Revise and Resubmit", along with a disclaimer that if something doesn't fit it's not our fault. This is SOP in bridge construction.

From the perspective of a Formwork Engineer, it is very frustrating to have a set of plans stamped or noted on only the cover sheet.

Shop drawings, for formwork, exist to rectify differences or conceptual problem in the design or in the coordination of the contract drawings.

The changes made and noted on these drawings is to become part of the contract. As such, if a change is noted on a page, but there is no stamp nor signature to associate the markup with, the validity of the markup is in question. The next step becomes a formal RFI which negates the benifit of the shop drawing review process, as there is little point in preparing a shop drawing for submittal if consise reasonable markups or revisions will only be generated in an accountable way with an RFI and RFI response.

It can certainly seem like a blame game or a way shift liability, but the goal and focus must always be to give the customer the product paid for, not always everything he/she wants, but what is guaranteed by contract and what is reasonable above and beyond.

Anything that comes in the door in our office is stamped recieved that day. Anything reviewed is stamped page by page. Specs and generic product data is stamped on the cover page.

All drawings are stamped, dated and initialed or signed. Even drawings that do not require a seal are signed such that drawings have a point of genesis, not necessarily to blame, but to fill in pieces of the puzzle should a question arise.

DTGT2002,

I've worked in several states and the only formwork shop drawings I was required to check were for the deck, whether SIP or removable forms. Again, all bridge work. I've never been asked by a client to check formwork for a substructure, barrier, etc.
