The most powerful and the simplest construction bidding, estimating and scheduling system.
For commercial general contractors. An invitation to bid lands in your inbox; Keelstone builds the job folder, downloads the plans, splits the sheets, invites the right subs, levels their bids, verifies every number, and assembles the proposal. Then it runs the job.
Quantities from plans, specs and aerial imagery, with a source on every line.
Reads the whole set, extracts quantities across 25 trades, flags plan discrepancies with one-click RFIs, turns each addendum into a variance report, measures on the sheet or from satellite imagery, and answers questions about the documents. Do It Yourself in minutes, or Done For You with an estimator QA pass.
