The programme that orders your materials
A real CPM Gantt with WBS, dependencies and a critical path — carrying AED buy-window markers on every activity. Each material’s order-by date is derived from the programme, so when the critical path moves, the buy dates move with it.
Watch the buy dates follow the critical path.
Bars draw in, the critical path lights up, buy-window markers land on the activities — then a task slips, and the order-by dates re-sequence with it.
CPM, WBS and dependencies — not a static bar chart.
Break the job into a work-breakdown structure, link activities with finish-to-start dependencies and lag, and let the critical-path engine compute the chain that sets your finish date.
- WBS tree with parent phases and child activities, numbered 1, 1.2, 1.3
- Dependencies with lag — the critical path and slack are computed for you
- Day, week and month zoom, with milestones and a live Today line
- Priced BOQ elements roll up onto the activities they belong to
Order-by dates, derived from the programme.
Every material in the buy plan gets an order-by date: activity start minus the supplier lead time. The buy-windows sit as AED markers on the Gantt itself, so procurement and planning finally read from one timeline.
- Buy-window = activity start − supplier lead time, per material
- AED markers land on the activity that consumes the material
- A buy plan you can sort by order-by date and value
- Quoting and awards live in Procurement — matches carry over
| Material | For activity | Order by | Value |
|---|---|---|---|
| Rebar B500B, 16 mm | Superstructure | 12 Aug | AED 96k |
| Solid blocks 200 mm | Blockwork | 3 Sep | AED 74k |
| MEP first-fix kit | MEP first fix | 28 Sep | AED 128k |
| Ceramic floor tiling | Finishes | 21 Oct | AED 61k |
| Buy plan · this project | AED 359k | ||
See slip the week it starts — and re-sequence the buys.
Planned-vs-actual on every activity means a slip shows the moment it happens. When the critical path moves, downstream activities and their buy-windows re-sequence, so you order to the new dates instead of scrambling.
- Actual dates tracked against the plan, per activity
- Critical-path moves ripple to downstream activities automatically
- Buy-window markers shift with the activities they belong to
- Non-critical work with slack stays put — no false alarms
Estimate in
The priced BOQ and its elements flow straight into the programme — quantities, values and materials, per activity.
BOQ WorkspaceProgramme
The CPM engine schedules the work and derives every material’s buy-window from activity start and supplier lead time.
Procurement out
Buy-windows become RFQs and orders in Procurement — floated to suppliers on the dates the programme needs.
For contractorsSee the programme run your own project.
Bring a BOQ and a set of dates to the demo — we’ll build the programme, derive the buy-windows and show the slip story live, in AED.
