Built by people who've sat in the estimator's chair.
Construction estimation is one of the most skilled, most under-tooled jobs in the built environment. Estimators spend 12–16 hours reading every set of drawings — twice, sometimes three times — just to capture scope. Then they do it again on the next project.
Parapet exists to give that time back. Not to replace estimators — to free them from the parts that don't require judgment so they can focus on the parts that do: knowing your subs, reading risk, and winning the right bids.
What Parapet actually does
You build your ROD — manually or imported from your existing process — and review it in a split-screen interface against your drawings. Parapet adds AI where it counts today: quote parsing that maps subcontractor bids straight to your ROD, and a geo bid-list builder for finding the right subs.
Parsed and mapped to your ROD automatically
Bid lists built by trade and distance from the job site
Pilot target: reduction in estimating hours per project
Our approach
Intelligence, not automation
We don't replace the estimator. AI takes on the repetitive parts — parsing quotes, building bid lists — so the judgment stays with the professional who signs off.
Human-in-the-loop by default
Every item in the workspace is built for rapid review. Confirm what's right, correct what's off, document every sign-off.
Built for retail TI specifically
We serve retail tenant improvement GCs — not everyone. That focus means better AI prompts, better defaults, less configuration noise.
How we build
Estimators stay in control
AI parses the quotes. You do the review. Nothing gets submitted without your sign-off. The accountability stays with the professional — where it belongs.
Honest about AI's limits
Every quote our AI parses is mapped back to your ROD, and every mapping is yours to confirm before it's used in a bid. The review workspace puts anything uncertain in front of you first. No false promises.
One workflow, done well
General construction tools try to serve everyone. We focus on the estimator's workflow end-to-end — from drawing ingest to bid assembly — and do that job exceptionally well.
