How We Work

We learn your process.
Then we set QUANTUS up around it.

You don't get a login and a manual. We sit with your estimators, see how bid day really runs, and configure the platform — your phase codes, templates, subs and exports — so it fits the way your team works on day one.

01

Discovery

We sit with your estimators and watch a real bid move from plans to number. Where information gets lost, where things slow down, where people are retyping what a system should carry.

02

Setup

Your phase codes and cost types, division templates, subcontractor list, markups and owner-facing exports — loaded and organized before anyone starts a bid.

03

Go-Live

We work through live bids with your team. Plans go in, invitations go out, proposals come back and level into the estimate — with us there while the habits form.

04

Ongoing

Every awarded and lost job adds to your cost history. As your operation changes, we keep tuning templates, permissions and workflows with you.

Built by Estimators

Designed around the commercial estimating workflow — from the first plan set to the award — and proven on live bids before it was offered to anyone else.

Platform

One platform from plans
to award.

Everything an estimator touches on a bid, connected — so a price, a scope note or a sub's proposal is entered once and shows up everywhere it belongs.

Plans & Scope Review

Upload the set and it's split and named sheet by sheet. The AI reads plans and specs and suggests scope by phase code, with the sheet it came from — your estimators confirm before anything is official.

Plan Viewer & Takeoffs

Measure, count and mark up right on the sheet. Takeoffs link to estimate lines, and notes clipped from a sheet stay filed under the phase code they belong to.

Bid Invitations

Invite the right subs for each trade from your own database. Each sub gets a clean project page with scope, plans, addenda and a place to ask questions and upload their proposal.

Proposals & Leveling

Proposals land in the estimate as they arrive. Level subs side by side by scope line — included, excluded or priced — and select who you carry, round after round.

The Estimate

Hard costs, general conditions, markups and options in one live total. Budgets for blank lines, alternates and allowances kept out of the base, and every total agrees across the job.

Clarifications & Exports

Clarifications, allowances and alternates written next to the numbers they explain, and owner-ready exports that look like your company — not a spreadsheet dump.

RFIs & Addenda

Questions from subs and conflicts found in the documents become RFIs, go to the architect as one bundle, and the answers flow back out to every bidder.

Cost History & Budgets

Every finished estimate becomes cost history. Pull comparable jobs by type and size, see how they relate to the one in front of you, and build early budgets from your own numbers.

Subcontractor Database

Every sub tagged by the trades they cover, with their bid history and ratings from your PMs. Subs can register through your portal and keep their own information current.

For Subcontractors

Bidding with a contractor
that uses QUANTUS?

There's nothing to buy and no account to create. Contractors on QUANTUS send you a link to each project they'd like you to price.

  • Got an invitation email? Open the link in it — your project page has the scope, plans, addenda, a place for questions and your proposal upload.
  • Want to see a contractor's open projects? Enter the portal code they gave you to view what they're bidding and register your company.

Open a Contractor's Portal

Enter the code from the contractor's website or email.

Enter the code the contractor gave you.

Don't have a code? Ask the contractor's estimating team for their QUANTUS portal link.

About

Estimators who got tired
of the inefficiency.

We spent years building numbers in spreadsheets, chasing sub quotes by phone and losing bid day to a process that was slower than it needed to be. QUANTUS is what we wanted on our own desks: one place for the whole bid, instead of a spreadsheet and five separate tools.

The AI is there to read, sort and draft so your estimators move faster. It never makes the call — every scope line, price and selection is reviewed by the people responsible for the number.

"Most GCs don't have a talent problem. They have a process problem. We fix the process, then give it a platform that holds."

Data Privacy

Your plans stay yours.

Plan sets, sub proposals, your number — that's your competitive edge. Here's how we handle it.

Every company is walled off

Your projects, costs, subs and files are visible only to your own team. Subs and architects see only the pages you send them, through links tied to that one project.

Your data doesn't train anyone's AI

The AI runs on Anthropic's Claude through their commercial API. Under those terms, what goes through it isn't used to train their models.

Files stored privately

Plans, specs and proposals are kept in private storage so your team can open them any time. They're never public, never indexed, and never shared outside the project links you send.

We don't sell your data. Period.

Your project information stays between you and us. One AI provider, under commercial terms — that's the whole chain.

A data processing addendum is available on request.
