When estimating project costs, which factor can significantly influence scheduling?

Weather conditions can significantly influence scheduling during project planning and execution. Projects, particularly in construction and installation sectors, are often dependent on outdoor conditions. For instance, inclement weather such as rain, snow, or extreme temperatures can hinder progress and affect the safety of workers, leading to delays.

When estimating costs, it's crucial to factor in potential weather-related disruptions, as these can extend the timeline of the project and, in turn, increase overhead expenses, including labor and equipment costs. Adjusting the schedule to accommodate seasonal weather patterns or planning for contingencies can help mitigate these risks, ultimately providing a more accurate estimate for the project.
