Be Aware of Risks Associated With Shop Drawings and Submittals
Raising awareness of risks associated with shop drawings and submittals
design engineers produced a wide range of project drawings. Information contained in preliminary drawings is found in project bids or proposals, outlined in specifications within the scope of work. There are several risks associated with shop drawings and submittals that require awareness:
- Project specifications in the scope of work may not always be completely detailed
- Shop drawings may be produced with inaccurate dimensions or designs
- Submittals based on various preliminary drawings may be incomplete in detail
The major risk associated with shop drawings and submittals is project liability. This liability is related to defective materials and workplace safety while the project is under way. Another risk to consider is loss of time and project revenues. These liabilities clearly show the importance of insuring that shop drawings and submittals are reviewed by a licensed, Professional Engineer (PE) upon whom the responsibility to verify drawing specifications and submittals are complete and accurate to final drawings approved by the customer or general contractor overseeing the project.
Step-By-Step Process to Reduce Risk
The process of creating shop drawings requires expertise in drawing design for the construction industry. A project design manager will oversee the design group that produces shop drawings. The duty of the design manager is to insure that each drawing phase is represented clearly and accurately according to specifications. The next step is to submit the full complement of shop drawings in the draft phase to the construction manager for preliminary review. At this point, if changes need to be made to shop drawings, additional certified specifications should be produced by the construction manager or supervisor. These changes should be implemented into a revised set of shop drawings. Retain the preliminary drawings, should a comparison of the changes become necessary. Once all changes are met and verified, the project design manager can submit the shop drawings to a professional engineer who will signify the accuracy of the drawings with his name, license number and handwritten signature in the legend of the drawing.
Verify the Materials and Parts List
Create a materials and parts list from the project specifications and check the accuracy of the list against the shop drawings. Provide copies of the list to the project design manager and construction manager. If the list is approved as submitted, it can be forwarded with shop drawings and other documentation to the client.
