What is one common adverse site condition that can disrupt construction schedules?

Weather conditions are a common adverse site condition that can significantly disrupt construction schedules. These conditions can vary widely and include rain, snow, high winds, extreme temperatures, or even the threat of severe weather events such as hurricanes or tornadoes. Each of these factors can halt work on a construction site, as they may affect the safety of workers, the integrity of materials being used, or the actual construction processes themselves.

For instance, heavy rainfall can lead to unsafe working conditions and muddy site access, making it difficult for workers and machinery to operate effectively. Similarly, excessively cold temperatures can delay curing times for concrete or cause issues with other materials that are temperature sensitive. This reliance on favorable weather conditions highlights the critical nature of managing schedules with these variables in mind, as delays caused by weather can lead to cascading effects on project timelines, ultimately impacting the overall completion date and cost of the project.
