What it doesConstruction administration platform for architects covering submittals, RFIs, drawings, field reports, change documents, and pay apps in one record. AI features listed: AI Submittal Assistant (spec comparisons, summaries, Q&A, missing-item spotting), AI spec organization, and AI drawing detection. Imports submittals from Procore; works alongside Procore, Deltek, and Bluebeam. Vendor cites 20% faster submittal processing and 30% faster RFI response (vendor claims, not verified). Re-checked Oct 19, 2026: the homepage still lists the AI Submittal Assistant with spec comparisons, summaries and Q&A, Procore submittal import and side-by-side spec views, and now names Procore and Bluebeam (not Deltek) as systems it works alongside. Re-checked Oct 20, 2026: unchanged in substance; the homepage still names Procore and Bluebeam as systems it works alongside, lists Procore submittal import and the AI Submittal Assistant, and says mobile field reports work offline. Re-checked Oct 22, 2026: unchanged in substance (works alongside Procore and Bluebeam; Procore submittal import; AI Submittal Assistant; offline mobile field reports); the pricing FAQ says Part3 is typically bought by the prime consultant, most often the architect, running construction administration. Re-checked Oct 23, 2026: the pricing page's feature lists now also name MCP access and email filing, alongside AI spec organization, spec and document version tracking, a centralized drawing database, AI drawing detection, a Procore integration, the AI Submittal Assistant, mobile field reporting and contractor quote tracking. Re-checked Oct 24, 2026: pricing page feature lists unchanged (AI Submittal Assistant, AI spec organization, MCP access, AI drawing detection, email filing, document version tracking, Procore integration, mobile field reporting, contractor quote tracking). Re-checked Oct 25, 2026: homepage and pricing page unchanged in substance (CA platform for architects covering submittals, RFIs, drawings, field reports that work offline, change documents and pay apps; AI Submittal Assistant with spec comparisons, summaries and Q&A; AI drawing detection; Procore submittal import; works alongside Procore and Bluebeam; MCP access on both plans). Vendor percentages, firm counts and testimonials are not used.AI document-control platform whose agents work from one record of the contract documents, from design sets through construction to operations. Vendor describes: design-quality review that cross-references every spec section against every drawing sheet at 60/90/100% sets, with a second independent agent that tries to disprove each finding before it is filed; bid-stage reading of a solicitation (scope fit, a 93-point contract review, coordination risk, takeoff); submittal review with hundreds of checks per package against the governing spec, drawings and RFIs, returned marked up on the pages; RFI drafting and plan-set change comparison; and closeout to O&M records. On upload it splits specs into conformed sections, merges special provisions into the standard specs they amend, and attributes addenda and RFI answers paragraph by paragraph. Says it handles state DOT books, federal UFGS, railroad and port specs, naming Caltrans, WSDOT, FDOT, UFGS and BNSF as formats in production, and focuses on federal and public work. Lists Procore and Autodesk Forma Build two-way sync, SOC 2 Type II, and FedRAMP 20x in progress (vendor claims). Re-checked Oct 19, 2026: the homepage still describes design-quality review with a second independent agent that tries to disprove each finding, bid-stage solicitation reading, submittal review, RFI drafting, plan-set change comparison and closeout to O&M, and still shows SOC 2 Type II and FedRAMP 20x in progress. Re-checked Oct 21, 2026: homepage unchanged in substance (every spec section cross-referenced against every sheet at milestone sets, with a second independent agent that tries to disprove each finding; bid-day reading of a solicitation with a 93-point contract review; Caltrans, WSDOT, FDOT, UFGS and BNSF formats; Specset as the system of record or two-way sync with Procore or Autodesk Forma Build; SOC 2 Type II and FedRAMP 20x in progress, vendor claims). Second read Oct 21, 2026: the homepage now also lists a facilities and maintenance agent that turns the closeout record into assets, warranties, maintenance plans and work orders, and names email, MCP and a Specset CLI alongside Procore and Autodesk Forma Build; specset.com/pricing still returns not found. Platform-to-date counters on the homepage are vendor claims and not used.

The compliance line has changed: it now says Specset has filed a FedRAMP 20x Class A application that is under review, with a FedRAMP Marketplace listing (FR2631258135) at Initial Implementation and Class C being pursued, alongside SOC 2 Type II, CMMC Level 1 (self-assessed) and NIST SP 800-171 alignment (vendor statements).

Who it's forArchitects and other prime consultants running construction administration (pricing FAQ says the architect is usually the buyer). Relevant to GC estimators mainly as the other side of RFIs and submittals.General contractors, CM and engineering firms, owner's reps and EORs, and owners on federal, state and municipal programs (vendor wording). Directly relevant to heavy civil bidders reading DOT special provisions (our framing).

Where the vendor descriptions differ

  • Who buys it: Part3 says it is purpose-built for architects running construction administration, and its pricing FAQ says it is typically purchased by the prime consultant, most often the architect. Specset has pages for general contractors, CM and engineering firms, A/E firms and owners, and says federal and public work is its specialty.
  • Submittals: Part3's AI Submittal Assistant offers spec comparisons, summaries and Q&A, and it can import submittals from Procore. Specset says its submittal review runs hundreds of checks per package against the governing spec section and returns findings marked up on the pages with your firm's stamp.
  • Beyond submittals: Part3 covers RFIs, field reports (mobile, works offline), change documents, pay apps, drawing management with AI drawing detection, cost management and project analytics. Specset adds design quality review with a second agent that tries to disprove findings, bid screening with a 93-point review, RFI drafting with answer checking against the latest sheets, plan-set comparison, closeout and a facilities and maintenance agent; it says it slices owner-issued specs into conformed sections and revision-tracked sheets on upload, including state DOT, UFGS and railroad books.
  • Integrations and security: Part3 works alongside Procore and Bluebeam and lists MCP access on its plans. Specset says it can be the system of record or work with Procore, lists MCP, and states SOC 2 Type II and a filed FedRAMP 20x Class A application under review (vendor statements).
  • Pricing: Part3 publishes Core $150 and Complete $200 per user per month, billed annually in USD, with annual subscriptions starting at $9,000 a year and unlimited free collaborator seats; contact for more than 50 users or multi-year terms. Specset publishes no prices (Book a demo or Get in touch).
  • Not like-for-like: Part3 is the architect's CA record system with AI help on submittals; Specset is pitched at reviewing the documents themselves across the project and names contractors and owners as well as designers.
  • Not used here: Part3's percentages, firm counts and testimonials, and Specset's platform counters and cost figures (vendor content).
