Build a construction schedule by breaking the job into phases, listing tasks with realistic durations, linking dependencies, identifying the critical path, adding float for weather and inspections, and updating it weekly. A schedule that is never updated is a wish list, not a plan.
Start with five to ten phases that match how you actually run and bill the job, then break each into tasks. Starting with a two-hundred-line task list produces a schedule nobody maintains.
Link tasks so that moving one shifts the rest. Without dependencies, a Gantt chart is decorative. Finish-to-start covers most construction work; use lags for cure times, dry times and fabrication lead times.
The critical path is the chain of tasks that determines the completion date. Tasks off the critical path have float and can slip without hurting the end date. Knowing which is which tells you where to spend money to recover time.
Weather-dependent trades need explicit contingency days, not optimism. Inspections need lead time and a buffer for a failed first attempt. Both are predictable, so schedule them.
A weekly update with a client-visible schedule prevents most 'why is nobody here' calls. Subs who receive updated dates automatically show up on the right day more often.
WinkScope provides a three-level job, phase and task hierarchy with dependencies, drag-to-reschedule that cascades downstream, a live weather overlay, subcontractor work orders tied to tasks, what-if simulation for delays, and a client portal view of the schedule.
The longest chain of dependent tasks through a project. Any delay on a critical-path task delays the whole project, while tasks with float can slip without affecting completion.
Enough to absorb known risk: commonly 5% to 15% of duration for weather-exposed work, plus explicit buffers around inspections and long-lead materials.
