The phrase 'due diligence' in the contract refers to the contractor's obligation to verify what?

• A. The contractor's obligation to maximize profits.
• B. The architect's duty to expedite approvals.
• C. The contractor's effort to identify and address potential issues in the contract documents and site conditions, reducing risk of undetected errors.
• D. The owner's obligation to approve all changes.

Answer: (C)

Due diligence in this contract context means the contractor thoroughly reviews contract documents and site conditions to identify and address potential issues before they become problems. This involves checking for inconsistencies, ambiguities, missing information, and constructability or coordination concerns, as well as site constraints and regulatory requirements. The goal is to uncover risks early and take steps to resolve them or properly allocate them, reducing the chance of undetected errors that could lead to costly changes, delays, or disputes later on. This obligation is not about maximizing profits, nor about the architect expediting approvals, nor about the owner needing to approve all changes.
