If it becomes apparent that the Contractor's schedule will not be met due to the Contractor's fault, what does the Contractor agree to do?

When a Contractor's schedule is delayed due to their own fault, it is typically the Contractor's responsibility to take corrective actions to get the project back on track. Increasing the number of employees and extending work hours are practical measures that a Contractor can utilize to expedite work and ultimately meet the project's timeline. This response not only demonstrates the Contractor's commitment to fulfilling their contractual obligations but also addresses the immediate need for increased productivity to recover lost time.

The other choices do not directly facilitate the rescheduling of work completion: Increasing the number of subcontractors may not be a quick solution and could complicate management without guaranteeing timely completion. Accepting penalties does not resolve the issue of the delay; it is more of an acknowledgment of responsibility rather than a proactive measure to fix the situation. Improving the quality of work, while important, does not inherently address the timeframe issues and may inadvertently prolong the schedule even further if it results in additional work or revisions.
