Schedule shared equipment — cranes, lifts, hoists, formwork, temp power — across active projects. Auto-coordinates with sub CPMs and supplier lead times. Flags the lift conflict three weeks out, not the day before mobilization.
Seven categories cover most of what gets dropped on the floor when sub schedules shift. Each tracked separately because each has different lead times, cost structures, and supplier relationships.
Tower assembly + dismantle dates. Mobile crane day-of pours, lifts, and rigging picks. Operator unions on cost. A 350-ton mobile sitting idle for a day is $4–6K out the window.
Buck hoists, dual-cage personnel hoists. Tied to floor cycle. Demobilization timing matters — finish trades won't start until the hoist is gone.
The most-shared, most-conflicted category. Three subs want the 60' boom on Tuesday. Two will lose.
Tunnel, slab, column. Cycle-based. Stripping windows tied to compressive strength tests. Reshore tracking back-of-curtain.
Permitted, weather-sensitive, sub-specific. Often shared across MEP and curtain wall crews on the same elevation.
Fuel cycles, capacity ramp-up as MEP rough-in starts pulling load. Transition to permanent power is a milestone everyone forgets to coordinate around.
Cold-weather concrete, drywall mud cure conditions. Fuel logistics. Often arrives late because nobody owns the timing call.
Pickup + swap cycles. Truck routing windows. The least glamorous category. Also the one that creates the most field complaints.
Equipment scheduling lives in someone's head, a whiteboard in the trailer, or a shared spreadsheet that's three revisions behind reality. Then a sub's CPM shifts, nobody updates the equipment, and on Tuesday morning the lift shows up to a slab that isn't ready.
Day-rate plus operator. If the slab pour pushes a day, the crane was ordered for nothing. Most of the time it gets eaten as a cost-of-business line. We surface the count.
Smaller dollars per day, but stacked across 8–15 units on a typical mid-rise, idle days run $15–30K/mo when nobody's tracking utilization.
Equipment arrives, slab isn't ready, sub crew stands around for 2 hours, equipment leaves, comes back next week. Re-mobe fee + lost crew time.
Tower crane sections, 60-day lead. Specialty formwork, 30-day lead. If the CPM shifts forward and nobody re-orders, the supplier can't get it on site — you eat acceleration costs or schedule slip.
Three subs need the boom Tuesday. Two get it after lunch. Half a day of crew time lost waiting. Doesn't show up in your equipment ledger; shows up in your schedule slip report 3 months later.
Equipment-related cost leakage on a portfolio of mid-rise projects. The number scales with how much shared / rented equipment your firm uses. Bigger firms with portfolio-level equipment management already feel this number; smaller firms feel it as "why do we always seem short on cash this month."
The hard part isn't the scheduling. It's the re-scheduling. When the sub's schedule moves — and it always moves — the equipment plan should move automatically and the supplier should hear about it before the night before.
Equipment scheduling is most useful when it's reading from the schedule and writing to procurement — not living in a separate tool nobody updates.
Working on it. Phase 1 (beta): email-based supplier coordination — auto-generated emails with structured booking details, supplier confirms by reply or by clicking a confirmation link. Phase 2 (post-beta): direct API integration with United Rentals, Sunbelt, and 3–5 regional suppliers per major metro. The email path keeps the engine useful from day one for the long tail of small suppliers who don't have an API.
Same scheduling, different cost model — instead of rental day rates, we use the firm's loaded internal allocation rate. Most firms have one even if it's loose ("$650/day for our 80' boom"). Helps the portfolio view show which jobs are subsidizing equipment utilization and which are bearing it.
For union operators on cranes specifically: tied to the equipment booking. When the crane moves a day, the operator request moves with it. We don't replace the union dispatch — we just give the dispatcher accurate notice when something changes, with the activity context attached.
Limited beta targeting Q3 2026 for firms running 4+ active projects with significant shared-equipment exposure (tower cranes, hoist systems, large lift fleets). Priority for firms already using Schedule Risk — the integration there is what makes this work. Sign up to flag interest.
If you've ever paid for a day of mobile crane time the slab wasn't ready for — you're the firm we're building this for. Q3 2026 limited beta.
