PreBLD is the estimating engine for the feasibility moment a defensible construction number while the decision is still live.

What you get

Win the deal. Defend the number. Get your time back.

PreBLD is built for the feasibility moment — when a developer, GC, or design-build firm needs a construction number they can stand behind, not a guess. Here is what changes.

~10 min
From drawings to a number

First credible number wins the deal.

Whoever puts a defensible number on the table while the decision is still live beats whoever waits three days for a callback. PreBLD turns drawings into a Class C estimate in about ten minutes — fast enough to shape the deal in the room.

Real bids
Calibrated, not guessed

A construction number you can defend.

Your construction cost isn't a $/sqft guess anymore. PreBLD prices every division against real contractor bid data and hands your lender, client, or investment committee a division-level breakdown — at an honest ±15–20% Class C range you can stand behind.

A day
Back, every estimate

And the work that used to take a day is done before lunch.

A feasibility estimate runs 16 to 40 hours of manual takeoff, lookup, and trade-by-trade build-up. PreBLD absorbs it. You review, edit, finalize — and put that time back into the work that wins business.

The product

Built for the room, not the office.

Four surfaces, one workflow: describe the project, tune the lines, defend the number live, and send it before the meeting ends.

PreBLD Chat

Describe the project. Watch the number build.

Tell PreBLD what you’re building in plain English — or drop in drawings. A vision model detects scope, and division-level pricing materializes on the sheet as it works.

Tell me about the project — what are you building, and roughly how big?

Your projects stay private. The calibration gets shared. Project details never leave your workspace — only anonymized cost anchors feed the shared calibration, and that's what makes every firm's estimates sharper.
