Our project timeline estimator uses Critical Path Method (CPM) to calculate accurate project schedules. The calculator analyzes task dependencies and durations to determine the longest sequence of activities (critical path) that defines your minimum project duration, then adds contingency buffers for realistic client timelines.

Understanding Task Dependencies

Task dependencies define the logical sequence of work. Most construction follows Finish-to-Start (FS) relationships where one task must complete before the next begins. Proper dependency mapping ensures realistic schedules and helps identify opportunities for parallel work that can reduce overall duration.

• Sequential tasks create the critical path and determine minimum duration
• Parallel tasks can occur simultaneously to reduce overall timeline
• Dependencies ensure logical work sequence (foundation before framing)
• Critical path tasks have zero float - delays impact project completion
• Non-critical tasks have scheduling flexibility without affecting timeline
• Contingency buffer (10-20%) accounts for delays and uncertainties
