About

Join is a collaborative preconstruction and design‑phase management platform that unites contractors, owners, design teams, and trades around cost, timeline, and design clarity through a single interface. It centralizes all decisions, cost data, and stakeholder communication in real time, enabling users to visualize cost trending with rapid reporting, track decision history and assignments, compare cost and design scenarios side‑by‑side, and manage project risks, contingencies, and allowances without siloed emails or spreadsheets. Built to support thousands of decisions per project, Join aligns design concepts with preconstruction milestones to help teams hit budget, schedule, and vision targets. Its highly visual dashboard adapts to workflows such as Design‑Build, CMAR, IPD, IFOA, and TVD, while executive‑level views allow portfolio monitoring, precise future job estimation, risk mitigation, and performance benchmarking.

About

Piper is the AI operating system for preconstruction, built for general contractors' pursuit and estimating teams. Piper connects drawings, specifications, addenda, quotes, estimates and company knowledge so teams can generate scopes, level bids and review risk — with every finding linked back to the drawing, spec clause or addendum it came from. Scope Generation: turn drawings, specifications, addenda and company standards into source-backed trade scopes, so you know exactly what you are asking each trade to carry. Bid Leveling: compare subcontractor bids against the intended scope, so the low number does not hide an expensive gap. Final Bid Review: review the estimate against the project behind it, and focus senior attention on what still deserves judgment. Survey: turn your company's experience into a repeatable survey that captures what the team learns on every project. Piper is not a takeoff or estimating calculator, and it does not replace estimator judgment.
