From whom must approved submitted data for each fixture be obtained before roughing-in?

Obtaining approved submitted data for each fixture from the purchasing agent or project manager is essential before the roughing-in stage of plumbing installation. This process ensures that the fixtures being installed meet the project's specifications, design requirements, and compliance with applicable codes. The purchasing agent or project manager typically oversees the procurement of materials and fixtures, ensuring that they align with the budget and project goals. Their approval guarantees that the right products are selected and properly documented, which helps avoid issues during installation.

In this context, the architect, while influential in design, may not be directly involved in the procurement process and thus may not have the final say on fixture approvals. The contractor generally manages the project execution, but they rely on the purchasing agent or project manager for ensuring that the right materials are available. Additionally, while the plumbing inspector plays a crucial role in ensuring that installation meets code and safety regulations, their involvement usually comes after installation rather than during the approval of fixture data prior to roughing-in.
