Company profile
researched Aug 2026Part3 provides construction administration (CA) software purpose-built for architecture and engineering firms. The platform centralizes the documentation produced during the construction phase of a project — submittals, RFIs, drawings, field reports, instructions, change orders and pay applications — in a single system intended to replace email threads, shared drives and disparate point tools.
The product includes AI-assisted submittal review with specification comparison, summaries and Q&A; mobile field reporting with photo capture that works offline; automated drawing management with version control and AI-assisted organization; change order management with real-time contract adjustments; secure signing and stamping; and dashboards covering team performance, cycle times and project financials. Part3 maintains a centralized, traceable record of CA activity intended to support firms in the event of a dispute or liability claim. The platform is designed to operate alongside adjacent systems used on projects, including Procore, Deltek and Bluebeam, and supports importing submittals from Procore as well as collaboration with external consultants.

Market position
The company reports being used by more than 100 architecture firms and positions its product as a specialist alternative to general construction management systems for the CA phase.
Part3 positions itself as purpose-built for the architect's side of construction administration rather than for general contractors, combining AI-assisted submittal review, side-by-side specification views, automatic log updates and an auditable record of approvals in one system that works alongside contractor-oriented platforms.
Technology
The platform applies AI to construction administration workflows: comparing submittals against specifications, generating summaries, answering questions about documents, spotting errors, and assisting with drawing organization and version control. Mobile field reporting functions offline, and the system keeps a tamper-proof, traceable record of CA activity. Integrations connect Part3 with Procore, Deltek and Bluebeam.
Go-to-market
Part3 markets directly through its website using booked product demos and self-guided product tours, supported by published customer stories describing measurable CA outcomes at client firms.
