Which of the following should be documented regarding contractor problems?

Documenting the work schedule and the as-built schedule is crucial in managing contractor problems. The work schedule outlines the timeline for project completion, detailing what tasks need to be done and when. The as-built schedule provides a record of actual completion dates, reflecting any deviations from the original plan due to unforeseen delays, contractor issues, or other factors.

Having both the work schedule and as-built schedule documented allows project managers to accurately assess the impact of contractor problems on the overall project timeline. They can identify whether delays are due to contractor performance and hold them accountable for not meeting the established deadlines. Furthermore, this documentation is essential for defining responsibilities in disputes that may arise and for claims related to delays or cost overruns.

While the quality of materials used, weather conditions at the site, and external stakeholder opinions can all play a role in project management, they do not directly address the evidence needed to substantiate and analyze contractor problems in terms of timelines and contractual obligations as effectively as the scheduling documents do.
