Who is primarily responsible for keeping a construction project on schedule and within budget?

• A. Owner
• B. Designer
• C. General contractor
• D. Construction contract supervisor

Answer: (D)

The key idea is that on-site control of work flow and costs is concentrated in the person who directly oversees daily construction operations and coordinates all trades. The construction contract supervisor serves as the on-site manager who translates contract documents into real-time activities, tracks progress against the schedule, monitors expenditures, and handles changes and material deliveries that can affect timing and cost. By continually coordinating labor, materials, subcontractors, and sequencing, this role keeps the project moving on schedule and prevents budget overruns, or surfaces issues early so they can be addressed. While the owner provides funding and the designer sets the design, and the general contractor bears overall responsibility for delivery, the on-site supervisor is the primary figure responsible for enforcing schedule and budget discipline day to day.
