(Including Product Data Sheets)
Shop drawings are construction drawings provided by the general contractor which are utilized to facilitate compliance with the plans and specifications. They are:
supplementary to, and form part of the contract;
vital for monitoring contract compliance;
utilized in areas where some flexibility is required due to variations in product supply, fabrication or erection within the terms of the contract;
provide essential information on the contractor's proposed product submissions and the implementation strategy within the terms of the contract.
The requirement for their submission is specified in the Canadian National Master Construction
Specifications, Section 01 33 00, Clause 15. Specific shop drawing requirements are usually identified in the specification sections calling up the products in question.
There is a 'generic' quality review process utilized in Real Property Branch (RPB) for the review, stamping and signing of shop drawings and the project manager must ensure that all members of the project team are aware of their roles, responsibilities and liabilities related to this review. The review by RPB staff or by consultants is for the sole purpose of ascertaining conformance with general concept. It does not provide 'approval' of the detail design inherent in shop drawings (which remains with the contractor, or the facility owner in cases of a leased facility), nor does it relieve the contractor of responsibility for errors or omissions in shop drawings or for meeting all requirements of the construction and contract documents.
The general contractor should submit shop drawings bearing their approval/signoff directly to the project manager. In cases where this process is not followed, the consultant or RPB in-house designer should not accept the drawings, return them to the sender and advise them of the proper
process, or, forward the drawings to the project manager for action. Project managers have a legal responsibility to ensure that the review and signing of all shop drawings takes place. RPB and consultants staff must never provide a statement of 'approval' of the contractor's shop drawings as this could constitute an unconditional endorsement of the drawings.
This table lists the shop drawing review process roles and responsibilities of the Consultant or In-house Designer, the Project Manager and the contractor.
