What document should be referenced if discrepancies arise with the blueprints?

The appropriate document to reference when discrepancies arise with the blueprints is the Equipment Plan. The Equipment Plan outlines the specifications and locations of the equipment that will be used in the project, which can help resolve any inconsistencies noted in the blueprints. By cross-referencing the equipment's intended placement, size, and requirements with what is depicted in the blueprints, any differences or errors can be identified and clarified.

Change Orders, while crucial for documenting modifications to the project scope or plans, serve specific purposes and may not directly address the underlying issues presented by the blueprints. The Project Schedule provides a timeline for project tasks but does not incorporate the technical details needed to resolve blueprint discrepancies. Inspection Reports focus on compliance and performance but may not detail the technical aspects related to equipment placement. Thus, the Equipment Plan is the most relevant document for reconciling any differences seen in the blueprint.
