What is resource leveling in construction scheduling?

Resource leveling adjusts activity timing to smooth resource demand peaks within availability limits, potentially extending project duration. Process: (1) Calculate resource requirements from activity durations and crew sizes, (2) Identify over-allocation periods exceeding capacity, (3) Delay non-critical activities within float to reduce peaks, (4) Extend critical activities if necessary (extends project). Resource-constrained scheduling priorities activities when resources limited. Balance between minimizing duration and managing resource fluctuations. Important for equipment-intensive projects or limited specialty labor.
