Find what your schedule missed — before the owner does.
IPSES is private pre-submission QA for contractors and subcontractors. Upload the plan documents you choose, add your proposed schedule and estimate, and get a side-by-side reconciliation that shows every scope gap, sequencing conflict and lead-time trap — plus the revenue you're leaving on the table.
Private by default. Your documents are never used to train models.

Schedule days of exposure found on the critical path
Indicative averages. Every contract and project varies in risk and revenue.
The cost of a clean-looking schedule
Schedules get rejected for things a human reviewer can't see in a week.
Scope you never priced
A med gas manifold on sheet P-402 that never made it into the estimate is not a scheduling error — it's a six-figure hit to your margin, discovered after award.
Lead times that don't reconcile
A 38-week AHU released 14 weeks late doesn't fail today. It fails eighteen months from now, on the critical path, in front of the owner.
Money left on the table
Idle gaps, duplicate mobilizations and stick-built scope that could be prefabricated. Risk gets attention. Recoverable margin usually doesn't.
How it works
A side-by-side review that runs in hours, not weeks.
Ingest
Plans, specifications, addenda, BIM and quantity data, RFI logs, contract exhibits and your proposed CPM schedule and estimate.
Reconcile
Frontier models read what the contract documents say should be built and compare it, line by line, to what your schedule and estimate say will be built.
Flag
Omissions, sequencing conflicts, missing logic, unrealistic durations, resource conflicts, lead-time risk, spec-vs-drawing conflicts, float and scope gaps.
Respond
Toggle the checks you want, pick the findings you include, and generate a review package or a drafted response to the owner and their consulting auditors.
The check library
We reconcile what the contract documents say will be built against what your schedule and estimate say you will build.
Every gap between those two versions of the project is either margin you are about to lose or revenue you are about to leave on the table. The individual checks, thresholds and calibration are proprietary and shown live during your review.
Scope integrity
Work the documents require that your schedule and price never account for — the most direct route to lost margin on a fixed-price submission.
Schedule logic
Dependency and sequencing defects that make your dates indefensible in a delay claim and hand the owner the argument.
Execution reality
Durations, crews, procurement and inspection timing that field production cannot actually deliver as drawn.
Compliance & upside
Addenda and approval dependencies you must reflect, plus sequencing you can compress to release revenue earlier.
Integrations
It plugs into the stack your submission is already built in.
No re-keying, no parallel system of record. We read your schedule and documents where they live, and reason over them with frontier models — so nothing is missed and your team keeps working the way it already does.

Negative risk
What it could cost you
- Missed scope that erodes bid margin after award
- Sequencing that cannot physically be built as drawn
- Long-lead equipment that lands on the critical path
- Inspection, permit and commissioning gaps that stall turnover
- Float and logic defects that get the schedule rejected outright
Positive opportunity
What it could earn you
- Idle time between phases that compresses with no added risk
- Procurement resequencing that saves days and locks price holds
- Duplicate mobilizations that collapse into one
- Prefabrication alternates the specification already permits
- Change-driven scope you're entitled to price and currently aren't
Built around your scheduler, not instead of them
We don't replace schedulers. We give them their week back.
Your scheduler shouldn't spend four days cross-checking sheet numbers against activity IDs. IPSES does the mechanical reconciliation across every document in the set, then hands your team a ranked, evidenced list to exercise judgment on. Time moves from document-chasing to the decisions that actually protect the bid.
Side-by-side review
Documents on one side, schedule on the other, with every link traced.
Highest-level security
Encryption in transit and at rest, tenant isolation, SSO, and zero model training on your data.
Representative finding
Air handling units released 14 weeks after required order-by date
- Source
- Spec 23 73 13 — p. 7, §2.1.B
- Affected activity
- MEP-2210 — AHU Submittal & Fabrication Release
- Financial impact
- $1,240,000
- Schedule impact
- 14 days, critical path
- Confidence
- 94%
Recommended action: pull MEP-2210 forward to Nov-2026, add an early-release procurement activity, and confirm the 38-week lead time in writing before submission.
No cost, no commitment
Your first project is free — so you can see what you've been missing.
Send us one live pursuit. We'll run the full review against your own documents and walk you through every finding, the evidence behind it, and the dollars attached. If it doesn't find anything worth acting on, you've lost nothing.
