SealedIron turns a line in your schedule into a sealed request for bids. Up to five rental companies you choose compete on your dates. Each bid names its own extension uplift, 0 to 10%, and that number is locked before the machine ever ships.
Import from Primavera P6, Microsoft Project or Procore and link it to the job. The activity ID, start and end come across exactly as scheduled. No retyping dates.
Class, spec, quantity, bare or operated, hours per day, fueling, delivery window and gate. One form, written the way a superintendent talks.
Enter the contacts for up to five rental companies. Bids are encrypted on the bidder's machine and stay sealed until the opening you set.
Every bid opens in the same second. The bid tab lands leveled: same scope, same exclusions, gaps flagged, blanks never treated as zero.
The rental agreement writes itself with the extension uplift already fixed. The rental company commits to its own delivery and pickup dates. E-sign, export to your ERP, and the fee invoice goes to the supplier.
Publish the schedule change and the extension notice goes out by itself, at the locked rate, with the new pickup date. No renegotiation call.
Every bid carries a day rate, bid total divided by activity days, and an extension uplift the bidder chooses between 0 and 10%. When your schedule pushes the activity end, the added days bill at the day rate plus that uplift. Nothing else. The rule is in the bid form, so a supplier agrees to it by bidding.
A bid is encrypted before it leaves the supplier's browser. SealedIron stores only the sealed copy. At the opening, every bid decrypts at the same moment and the bid tab appears to every authorized user at once.
Each bid gets a fingerprint and a timestamp in a tamper-evident log. After opening, anyone can recompute it and confirm the number is the one the supplier sent. The opening record, one PDF per request, is what an owner or an auditor asks for.
Single sign-on (SAML and OIDC). Roles by company, region and project. Full audit trail of who saw what, when.
Private vendor mode by default. Your activities and dates are visible to the bidders you invite and no one else. Cross-contractor marketplace is opt-in.
P6, MS Project, Procore in. Agreements, awards and fee invoices out to your ERP. API for everything the screen can do.
The rental agreement is between you and the supplier. SealedIron holds the fee agreement with the supplier, and nothing else.
Free for the contractor. Suppliers pay a success fee on awarded rentals, tiered down as rental value goes up. No fee on a request that is not awarded.
SOC 2 program in progress; report available under NDA on request. Data stays in the United States.
You bid on a machine, a class and a window you can actually plan a fleet around. No fishing requests, no "what's your best number" phone calls after you have already submitted.
Twenty-five years of chasing iron taught me two things. Nobody should see a number early, and the overrun should cost what the bid said. That is the whole company.
SealedIron is built by a working general contractor, on the same rules a good estimating office already runs by: every bidder prices the same scope, nobody shops a number, and a blank is never a zero.
The first release runs in private vendor mode with a small group of design-partner contractors. If your company moves heavy iron on a schedule and has been burned by week-four rate calls, we want to talk.
Thirty minutes. Your schedule, your vendor list, a sealed opening on screen. Design-partner slots are limited to contractors with active heavy-civil, industrial or multifamily work.
