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.

The order-by story

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.

A real CPM programme: five activities, planned on the timeline.
A real programme

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

The buy plan

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

Slippage

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 Workspace

Programme

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 contractors

See 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.
