What is the procedure for informing the Architect/Engineer about a desired change in a shop drawing?

The procedure for informing the Architect/Engineer about a desired change in a shop drawing involves making the change directly on the shop drawing and clearly specifying the adjustment in the accompanying Letter of Transmittal. This method is effective because it allows the Architect/Engineer to see exactly what changes have been made and understand the context within the existing drawings.

By making the change on the shop drawing, you are providing a visual representation of the modification, which can lead to clearer communication and understanding. The Letter of Transmittal acts as a formal documentation method that outlines the changes and any additional information that may be relevant, ensuring that all parties are on the same page regarding the update.

Other options do not fully meet the best practice for the scenario. For example, submitting a formal request letter could initiate the conversation but may not effectively convey the necessary visual context. Notifying by phone lacks the documentation needed for formal records and can lead to misunderstandings. Sending a revised contract letter might be relevant for contract changes but is not the appropriate initial step for addressing changes in shop drawings. Overall, communicating changes directly on the shop drawing, coupled with a detailed transmittal, aligns with industry standards for clarity and efficiency.
