About
DWGdrop is a web-based construction bid and drawing collaboration tool for contractors, estimators, subcontractors, architects, and engineering teams. It supports sending drawing packages and requests for quotation (RFQs) to trade partners, who can review materials and submit quotes through shared links. The browser-based workspace is described as supporting DWG, DXF, PDF, and spreadsheet-based bills of quantities, allowing teams to view and measure drawings and review quantities without a desktop CAD application. DWGdrop also provides RFQ status tracking, drawing revision handling, project questions and answers, and side-by-side quote comparison to help teams coordinate bid invitations and evaluate subcontractor responses. The workflow is intended for construction procurement and estimating teams exchanging drawings and bids with external partners.

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.
