The site plan, on one timeline — and it tells you what’s late.
If your plan lives in Excel and moves on WhatsApp, nobody knows which delay actually matters. This Gantt does — it computes the critical path while you drag.
Everything a site plan needs. Nothing you’ll never use.
Timeline
Phases and their tasks as bars. Day, week or month zoom, a today line, Sundays and holidays shaded.
Drag to plan
Move a bar, drag its edge to resize, drag a handle to link. FS, SS or FF, with lag in days.
Critical path & float
Computed live. The chain that decides your finish date turns red; every task shows its float.
Push what follows
Move a task and see which dependent tasks would shift — before saving. Move all, or only this one.
Working calendar
Mon–Sat by default, holidays per workspace or per project. "10 days" means 10 working days.
Baseline
Freeze the plan. Ghost bars and slip-in-days show how far reality has drifted.
Payment gate padlock
A stage waiting on approval or client payment shows a lock — with the reason.
Milestones & buffers
Diamonds for dates that matter. Contingency buffers that never sit on the critical path.
Owners & progress
Assign a task to a person. They report progress from My Work on the phone — without moving dates.
Undo / redo
Ctrl-Z any drag or link. Refused if a colleague changed the row in between.
Import from Excel/CSV
Phases, tasks, dates, owners and predecessors (3FS+2 style) — checked row by row before saving.
Search, filter, export
Search, filter, sort, reorder, fullscreen, compact — and export to Excel or print to PDF.
Lookahead
The next three weeks as a day grid — made for the site meeting.
Client view
The client portal shows phase-level progress only.
From Excel sheet to living plan in an afternoon.
Import or add tasks
Bring your Excel/CSV — phases, dates, owners, predecessors — checked row by row. Or type tasks straight in.
Drag and link
Move bars, link tasks, set the calendar, freeze a baseline. The critical path updates as you work.
Share the plan
Owners report progress from their phone, the client sees phase-level progress, and you export or print when asked.
Stop planning in a sheet the site never sees.
On Growth and Scale plans. Starter keeps the simple phase list.
