If you run construction procurement off a Critical Path Method schedule, you already know the gap. Your CPM lives in Primavera P6 or Microsoft Project. Your procurement deadlines sit in a spreadsheet that someone updates manually. When the schedule moves, someone has to go back into that spreadsheet and recalculate everything by hand. On a project with 300 line items, that is not a realistic process.

PLOT is built to close that gap. Here is exactly how the schedule connection works - and what is available if you are not using a CPM tool at all.

No CPM Schedule? PLOT Still Works.

Before getting into the schedule connection, one clarification: PLOT does not require a CPM schedule to be useful. Required On Site dates can be set manually on any material order. Lead times, deadlines, and trade check-ins all work the same way regardless of whether the ROS date comes from a schedule activity or a date picker.

The CPM integration is an upgrade, not a prerequisite. It automates the date-setting that you would otherwise do by hand, and it keeps those dates current when the schedule moves. But teams that do not use P6 or MSP, or that are early in a project before the schedule is finalized, can run PLOT's full procurement workflow on manual dates from day one.

The Philosophy: Start with Required On Site, Work Backward

PLOT's procurement approach starts with one anchor date: Required On Site. Every upstream deadline is derived from there, working backward through your configured durations.

After importing your schedule file, you link each material order to one or more CPM activities by selecting them from within PLOT. That activity date becomes the Required On Site date for that order. PLOT then derives every upstream deadline from that date, working backward through your configured durations.

This is what replaces the manual spreadsheet. Instead of a project engineer recalculating dates every time the schedule shifts, the system does it.

How Deadline Derivation Works

Once a schedule activity is linked and a Required On Site date is set, PLOT derives deadlines using the following logic:

Required On Site - Shakeout Days - Lead Time = Order Deadline

Order Deadline - Order Duration = Approval Deadline

Approval Deadline - Review Duration (x submittal cycles) = Submittal Deadline

Shakeout Days account for the time needed to offload, sort, or stage material before installation. They only apply when the ROS date is driven by a schedule activity - not when it is set manually. Lead time is entered by the trade and covers manufacturing, warehouse, and freight. Review duration reflects how long you expect the architect or engineer team to turn around the submittal, with cycles factored in for revise-and-resubmit scenarios.

Every one of these deadlines is derived from the linked activity date and your configured durations, not typed. When inputs change, the derived dates update.

How the Schedule Connection Actually Works

You import your schedule file directly into PLOT. PLOT supports direct P6 integration via Primavera P6 XER or XCR file import, and direct MS Project integration via MPP file import. Once imported, you open each material order and click the schedule icon to select the specific activity or activities that drive that material's Required On Site date. PLOT reads the activity date and derives every upstream deadline from there.

This is not a live sync. When your schedule changes, you upload the revised file and PLOT re-reads the activities. The process is straightforward: export from P6 or MSP, upload to PLOT, and the linked deadlines update across every connected line item.

For teams using Procore's native schedule, PLOT connects directly and pulls activities without a file upload. On the submittal side, PLOT syncs with Procore on a daily basis, reading submittal statuses so your procurement log reflects current approval state without manual updates. PLOT reads from Procore - it does not write back.

If You Already Use Procore, PLOT Is the Natural Next Step

A common question is whether GCs running Procore need a separate logistics tool at all. The answer is that Procore and PLOT solve different problems and work better together than either does alone.

Procore manages submittals, RFIs, daily logs, and field documentation. It does not derive procurement deadlines from schedule activities, automate trade check-ins for lead time and order confirmation, manage gate reservations and delivery slot booking, or provide driver wayfinding to specific drop-off locations. Those are PLOT's functions.

For Procore users specifically, the integration is straightforward: PLOT connects to Procore's schedule to pull activities, syncs submittal status daily, and logs delivery arrivals and departures back to the Procore daily log automatically. Your existing Procore workflow does not change. PLOT adds the procurement deadline tracking and jobsite delivery coordination layer that Procore does not have.

If you are already in Procore and managing procurement deadlines in a separate spreadsheet, PLOT is the direct replacement for that spreadsheet - connected to the Procore data you are already maintaining.

Pull Schedule and Push Schedule

PLOT runs two views simultaneously.

The pull schedule shows deadlines derived from the Required On Site date, working backward through your configured durations. This is your plan. It tells your team what needs to happen and by when based on the schedule and lead times.

The push schedule tracks actuals and anticipates the downstream impact. When a submittal approval comes back late, or a trade updates their order date, PLOT re-forecasts every remaining milestone based on what has actually happened. Instead of discovering a delay when the truck does not show up, you see it weeks out when there is still time to act.

The two together turn your procurement log from a static document into something that reflects what is actually happening on the project.

What the Trade Workflow Looks Like

Once PLOT has the schedule connected and deadlines derived, it sends each trade a weekly checklist showing only their action items for that week. The trade clicks through from their email, lands on a mobile-optimized view, and inputs things like lead times, order dates, and ship date confirmations directly from their phone.

No login required. No training needed. The GC team gets an audit trail of every update without chasing anyone down.

Where It Gets Complex

On a straightforward project with one submittal per material per activity, the setup is simple. PLOT is also built for the reality of how procurement actually works: one submittal with multiple materials on it, one material being ordered in phases tied to different activities, multiple submittals that all need to be approved before an order can be placed.

That complexity is mapped visually in PLOT so the PM team can see exactly how each order connects to the schedule, and so the system knows which deadlines to flag when something slips.

Vendor Coordination After the Order Is Placed

CPM integration handles the deadline derivation side. Vendor coordination handles what happens after the order is placed.

Once a trade confirms an order date and ship date in PLOT, the system schedules automated check-ins as the ship date approaches. The vendor receives a simple confirmation request - no login required - and responds with a confirmed or revised date. If the date has moved, PLOT's push schedule recalculates every affected downstream milestone immediately. The project team does not find out about a vendor delay when the truck does not show up. They find out weeks earlier when there is still time to respond.

Delivery Sequencing from Procurement to Site

Procurement scheduling and delivery sequencing are the same problem at different points in the timeline. PLOT connects them.

When a confirmed ship date is in the procurement log, it feeds into PLOT's delivery coordination system. The trade schedules their delivery slot against the site rules - gate availability, equipment reservations, concurrent delivery limits - so the material arrives when the site can actually receive and install it. A delivery that arrives when the crane is booked or the laydown area is full is not a successful delivery. PLOT ensures the sequencing is coordinated from the order date all the way to the gate.

The Result

When the schedule is connected and lead times are entered, PLOT knows what needs to happen on every material line and when. Trades get automated check-ins. The GC team sees what is at risk before it becomes a field problem. And when the schedule moves, re-importing the updated file and re-linking activities is all it takes to keep the entire procurement log current.

PLOT connects to Primavera P6, Microsoft Project, and Procore for procurement deadline management and delivery coordination. If you are managing procurement deadlines out of a spreadsheet that you update by hand when the schedule changes, book a demo at getplot.com.
