Adding details without approval which affects other trades

This memo clarifies the process for handling drawing approvals and issuance to ensure project coordination and minimize potential errors.

Drawing Approval Reviews:

When receiving approved drawings, carefully review them for any markups that may significantly impact other trades or existing structural elements (e.g., slabs, foundations, anchor bolts).

Example: If an approved drawing introduces a slab pocket where none existed in the original design, ensure the following steps are taken:

• Verify Slab Status: Issue an RFI (Request for Information) to determine the current status of the slab construction.
• Coordinate with Relevant Parties: Communicate the design change to the construction crew responsible for pouring the slab.
• Provide Updated Drawings: Issue revised slab drawings reflecting the pocket addition.

Failure to take these steps can lead to costly rework and project delays.

Issuing Drawings Before Approval:

Construction drawings should only be issued prior to approval if specifically requested by the client. In such cases, the drawings must be clearly marked and include a disclaimer.

Scenario 1: Client Does Not Require “For Construction” Marking

• Issue a full set of drawings marked “Issued for Approval” (IFA).
• Include a disclaimer stating that the drawings are not yet approved and their use is at the client’s own risk.

Scenario 2: Client Requires “For Construction” Marking

• Issue the drawings marked “For Construction.”
• Include a disclaimer stating that the client was informed of the drawings’ unapproved status but requested them for construction at their own risk.
• Obtain a written statement from the client acknowledging their request and acceptance of responsibility.

This process ensures clear communication and accountability in the drawing issuance process, mitigating potential risks associated with using unapproved drawings.
