31.3

Expand definition of shop drawings and scope. Indicate if the plan is not properly developed, it will be up to the contractor to finish developing the design through a "shop drawing."

Shop drawings are detailed plans that translate design intent. They provide the information necessary to manufacture, assemble and install all the components; Ensuring that the final product aligns with the designer’s vision, meets all relevant specifications and coordinate all the related trades as well as adjust as necessary to the existing conditions and any unforthseen condition.

The primary purpose of shop drawings is to translate design intent into actionable more precise information. They serve as a communication & coordination tool, facilitating a clear understanding of the intricate details and specifications outlined in the architectural and engineering plans. Shop drawings help ensure that the final product meets safety standards, design criteria, and client expectations.

As requested in the project specifications, the contractor is responsable to porvide shop drawings for all trades.

The only responsibility is to install and construct the project as per the documentation received. The contractor cannot be responsible for any design flaws.

In regards to the note H at Sheet F001, related to Fire sprinkler system:

The contractor is responsible for preparing shop drawings to identify conflicts and in that case, if a conflict is found, solutions will be evaluated and, if a PCN is required, it will be negotiated.
