Run the whole project from one command layer
Estimating, scheduling, RFIs, submittals, change orders, and pay applications — every phase of the build on a single AI-native record. Stop re-keying between point tools and chase fewer fires.
The problem
Built for the way GCs actually run jobs.
Disconnected tools leak time and money between phases. ErectOS closes the gaps GCs feel every day.
The challenge
Estimating, field, and finance live in separate tools that never reconcile.
How ErectOS solves it
One record from takeoff to final pay app — the estimate flows into the budget, the budget into the forecast, with no re-entry.
The challenge
RFIs and submittals stall in inboxes and blow the schedule.
How ErectOS solves it
Every RFI and submittal is tracked with owners, due dates, and an AI agent that triages and routes before items go late.
The challenge
Change orders erode margin when they slip through unbilled.
How ErectOS solves it
Change events become priced change orders with a full approval trail — nothing executed gets left off the next draw.
The challenge
You find out a job is over budget weeks after it happened.
How ErectOS solves it
Live cost, forecast, and cash-flow roll up the moment something changes — variance shows up while you can still act on it.
End to end
One platform from dirt to done.
Preconstruction, field execution, and project financials on the same system — no gaps between phases.
Estimate, tender, and buy out
Takeoffs, ErectBuilder 3D models, and side-by-side bid leveling carry straight into the project budget.
Run the field from any device
Daily logs, RFIs, submittals, and drawing markups capture on or offline and sync the moment you reconnect.
Keep every trade sequenced
A living critical-path schedule with baseline-vs-actual bars surfaces slippage before it costs you.
Bill and forecast with confidence
AIA-style pay applications, cost-to-complete forecasting, and live cash flow keep the numbers current.
One system behind the whole jobsite
Not a stack of point tools — a single platform every role and every phase runs on.
Modules for GCs
The toolkit, on one record.
Every module a general contractor leans on — connected, so data flows between them automatically.
The platform
Reliable, extensible infrastructure for every stack. A shared kernel of auth, workflow, events, and AI under every module.

30+ domain agents reason over your project data — every workflow has a copilot entry point.
Four-layer access control
Middleware, RBAC, ABAC policies, and org/building scope across 58 construction roles.
Open APIs & webhooks
REST and webhook APIs for logs, RFIs, submittals, schedule, and cost data.
Audit trail on everything
Every action logged and attributable. Encrypted in transit and at rest; never used to train models.
FAQ
General Contractors, answered.
Yes. The full GC lifecycle is first-class — estimating and buyout, field execution (daily logs, RFIs, submittals, drawings), scheduling, and project financials (budgets, pay applications, forecasting). It is designed for commercial and multi-family GCs, not single-family homebuilders.
