Piper is the AI Operating System for Preconstruction. General contractors' estimating and preconstruction teams use it to turn a fragmented pile of project documents into a repeatable preconstruction system.
Too much preconstruction time is spent assembling information, not improving the work. Days are lost finding, extracting and reconciling information across drawings, specs, addenda, quotes, schedules and spreadsheets. Historical costs, company standards and lessons learned stay scattered across files and people. Senior team members cannot personally review every scope, bid, estimate, schedule and project decision.
How it works
Unify the project. Bring drawings, specs, addenda, subcontractor quotes, estimates and spreadsheets into one connected project context.
Apply your company knowledge. Piper combines the live project with your historical data, templates, standards and expert checks.
Produce and verify the work. Create and review scopes, bid leveling sheets, estimates, project reviews and other preconstruction deliverables in your own formats, with every finding linked to its source.
Use cases
Scope Generation. Know exactly what you're asking each trade to carry. Turn drawings, specifications, addenda and company standards into source-backed trade scopes.
Bid Leveling. Know what you're actually carrying. Compare subcontractor bids against the intended scope so the low number does not hide an expensive gap.
Final Bid Review. Challenge the estimate before you stand behind it. Review the estimate against the project behind it and focus senior attention on what still deserves judgment.
Survey. Ask the right questions on every project, and make the next one better. Turn your company's experience into a repeatable survey that captures what the team learns.
Piper removes busy work from the critical path and turns the package into decision-ready, source-linked clarity.
