Seven tools today. One engine. Room for what you need next.
Substation Estimating
Read vendor drawings from every major EPC and engineering firm. Produce professional-estimator parity in minutes, with every number traceable to the sheet it came from.
MV Collection System
Upload a site layout, one-line diagram, or cable schedule. A full bid drops in 5 minutes with sub-2% accuracy.
Bid Leveling
Compare subcontractor bids side by side. Flag exceptions, normalize scope, choose confidently — and see what each vendor left out.
Spec Analysis
AI reads specification documents. Extracts requirements, flags exceptions, cross-references to project scope — and cites the page every answer came from.
Project Scheduler
Timeline management integrated with bid data. Tasks, dependencies, and what is actually driving your finish date. Substation scope for now.
Budget Estimator
Put a credible number on a project before drawings exist. Scope inputs, market conditions, and commodity movement are weighed against your own completed bids — so the budgetary figure you hand a client is grounded in what your firm has actually built.
Proposal Generator
The bid is done — now the proposal is due. Scope narrative, inclusions, exclusions, clarifications, schedule, and pricing draft straight from the approved estimate, in your firm's template and your firm's language. The estimator edits and signs off instead of starting from a blank page.
And whatever your process needs next
These seven are what's shipping today. The extraction engine underneath them is general — which means a tool that doesn't exist yet is a build, not a rewrite. If your team runs a step no software has touched, that becomes tool number eight.
See how we build it with youDrawings to bid, in four steps.
Upload
Drawings, specs, cable schedules — whatever the estimator has. PDF, Excel, images.
Extract
AI reads like an experienced estimator. Materials counted, quantities extracted, vendor conventions understood.
Calculate
Your customizable calculation engine runs the numbers — your rules, your pricing, integrated with your systems.
Estimate
Real-time BOM. Estimator reviews, adjusts, overrides where judgment matters. Bid drops in minutes.
Case study: substation platform in production
A utility-scale renewables EPC ran a real substation bid through Takeoff Lab. Their professional estimator produced a $7,181,270.90 total. Our platform produced $7,183,887.74. A delta of 0.04%.
This is workbook-level parity on a real project — not a demo, not a synthetic dataset, not a curated benchmark. Real drawings. Real bid. Real accuracy.
The Brain — your firm's estimating intelligence.
Not a chatbot. Not a virtual assistant. Your firm's own institutional estimating knowledge, captured from every project and queryable in plain language. It learns from everything you put in — and compounds with every bid you run.
Other tools give you a bid. Takeoff Lab gives you a bid — and makes every future bid easier.
Avg $412/CY across the three most recent. Range $388–$441.
Primary vendor on 7 of 9 projects, secondary on 2. Breaker spec standardized since 2024.
11.4% blended — 9.8% EPC-direct, 13.1% subcontracted scope.
Your lead estimator — 1.2% mean variance across 14 completed bids.
Built to production standards.
Automated tests
Every calc engine change verified against real project math. Regression discipline built in from day one.

Reference standards
Engineering physics baked into the platform. Bid backup that stands up to audit.
Real-time reactivity
Every input surface updates the bid immediately. No refresh, no stale data. What the estimator sees is what the bid uses.

I came from preconstruction — takeoffs, budgets, proposals and schedules. I know what it takes to get a bid out the door, and how much of that work still runs on 20-year-old Excel workbooks and outdated, precarious workflows.
Takeoff Lab is built with a working EPC, on real drawings and real bids.
