Keep this bid so it is still here when the customer calls back. Every number on this form is saved together, under a name you choose, along with the figure it gave you, and restoring one puts the whole job back exactly as you priced it. Mark each one won or lost when you hear — the ones you have not heard back on stay listed as waiting, with how long they have been out. Once a few have come back, this panel says how long yours actually take, and how many are still out past that. Once enough of them have been decided, it also says whether the bids you save here have been landing differently lately than they used to.

Construction schedule
Edit the activities (JSON: id, days, after, optional crew, lag, name, exposed, and notBefore: a "YYYY-MM-DD" date before which an activity cannot start, such as a lumber delivery or a permit) and get the critical path, slack, dates with the crews you typed, and what a slip does to the finish. The durations are yours; none are shipped. Nothing leaves your browser.
Critical path. A forward pass gives each activity's earliest start, a backward pass its latest; zero slack means critical.
Crews. With a crew count per name, a greedy pass delays activities that would need more crews than you have. It is a heuristic, not an optimal resource schedule.
Calendar. Working days are Monday to Friday, less any holidays and weather days you list.
Questions
What is the critical path in a construction schedule?
The critical path is the chain of activities with zero slack: if any one of them runs late, the finish date moves by the same number of days. This tool finds it with a forward and a backward pass over the predecessors you type.
Does this tool know how long framing or drywall takes?
No. It ships no durations. Every duration, predecessor and crew count is yours, from your own crews and past jobs. The sample is only there to show the format.
How are weekends, holidays and cure time handled?
Weekends are skipped. Holidays and weather days are dates you list. Cure time or an inspection wait is a lag in working days after the predecessors finish. Weather is not forecast.
