In a design-build project, the general contractor discovers a more cost-effective structural system during the estimating phase. What should be the primary consideration before proposing this change?
Correct Answer
B) Owner's design requirements and performance criteria
In design-build projects, while contractors can propose alternatives, they must first ensure any changes meet the owner's fundamental design requirements and performance criteria before considering cost or schedule benefits.
Why This Is the Correct Answer
In design-build projects, the contractor has design responsibility but must prioritize the owner's fundamental requirements and performance criteria above all else. Any proposed structural system change, regardless of cost benefits, must first satisfy the owner's specified design intent, functional requirements, and performance standards. This ensures the project meets its intended purpose and contractual obligations before considering secondary benefits like cost savings or schedule improvements.
Why the Other Options Are Wrong
Option A: Potential cost savings to the project
While cost savings are important, they are secondary to meeting the owner's design requirements. A more cost-effective solution that doesn't meet the owner's performance criteria or design intent would be unacceptable, regardless of potential savings. The primary obligation is to deliver what the owner specified.
Option C: Availability of specialized subcontractors
Subcontractor availability is a practical consideration but not the primary one. Even if specialized subcontractors are available for the alternative system, the change cannot proceed if it doesn't meet the owner's design requirements and performance criteria. This is an implementation concern, not a fundamental decision factor.
Option D: Impact on project schedule
Schedule impact is an important consideration but secondary to meeting design requirements. A change that improves the schedule but fails to meet the owner's performance criteria would be inappropriate. The project's success depends first on meeting specified requirements, then on schedule optimization.
