Piper AI

AI preconstruction platform for general contractors that the vendor calls the AI operating system for preconstruction. Piper says it connects drawings, specifications, addenda, subcontractor quotes, estimates, spreadsheets and company knowledge (historical bids and costs, standards, templates, review questions and lessons learned) into one project context, with each finding linked to its source document. Its site (read Oct 28, 2026) lists five workflows: Scope Generation (trade-specific scopes with inclusions, alternates, allowances, coordination items and source references, flagging unclear ownership, gaps and overlaps before bids are solicited; the vendor says it is not a spec writer or a takeoff tool); Bid Leveling (reads subcontractor proposals in PDFs, spreadsheets and attachments, extracts base bid, inclusions, exclusions, qualifications, alternates, allowances, unit prices and addenda acknowledgments, and levels each bid against the intended scope rather than only against the other bids; your team decides what to carry); Final Bid Review (cross-checks the estimate against drawings, specs, addenda, scopes and bids for scope with no cost assigned, duplicated cost, stale or inconsistent information and unresolved risk); Survey (applies the company's standard project questions to each document set and flags items left unanswered); and Scheduling (drafts a CPM preconstruction schedule with WBS, activities, durations and logic, each activity linked to the source document and page, asks rather than assumes when information is missing, runs checks based on the DCMA 14-point assessment, and exports to Primavera P6 XER or XML and Microsoft Project XML). The vendor says Piper can work in the spreadsheets and files a team already uses and hand them back for review, and that it is neither a document chatbot nor a set of disconnected point tools; its homepage lists SOC 2 Type II (vendor statement). Official site: piper-ai.com, a construction preconstruction product (not related to the Leica Piper pipe lasers). Customer logos, testimonials and time-saving claims on the site are not used here.
