Where the vendor descriptions differ

  • Who runs it: Document Crunch describes construction teams managing risk from pursuit through closeout. Part3 says it is purpose-built for architects running construction administration, and its pricing FAQ says it is typically bought by the prime consultant, most often the architect.
  • Contracts and risk: Document Crunch lists auto redlining and version compare in pursuit, contract and spec inconsistency checks in pre-con, playbooks that surface obligations before work starts, and risk items tracked as open, overdue or done. Part3 does not describe contract risk review; it keeps a tamper-proof record of submittals, RFIs, field reports, instructions, changes and pay apps for when a dispute or claim comes up.
  • Submittals and RFIs: Document Crunch says Project Assist gets submittals, notices and RFIs ready for review and answers questions across every contract, spec and addendum. Part3's AI Submittal Assistant compares specs and submittals side by side, summarizes and spots missing items, and Part3 imports submittals from Procore and works alongside Procore and Bluebeam.
  • AI: Document Crunch is tagged AI-first; Part3 is tagged AI features added to an established product (AI Submittal Assistant, AI spec organization, AI drawing detection). Part3's plan lists also name MCP access.
  • Pricing (checked Oct 27, 2026): Document Crunch publishes no subscription prices; its trial page offers a 14-day free trial for up to 3 projects with full access and no demo call, under Trimble Offering Terms. Part3 lists Core at $150 and Complete at $200 per user per month, billed annually in USD, with unlimited projects and free collaborator seats; its homepage says annual subscriptions start at $9,000 a year, with further discounts for more than 50 users or a multi-year commitment. See each tool page for detail.
  • Security: Document Crunch's security page states a SOC 2 Type II attestation, AES-256 encryption at rest, at least yearly third-party penetration testing and SSO for customers who need it.
  • Not like-for-like: Document Crunch is contract risk software a builder runs on its own documents; Part3 is the design team's construction administration system on the other side of the submittal and RFI exchange. A GC might meet Part3 as the architect's tool rather than buy it.
  • Not used here: Part3's speed and time-saving percentages and firm count, Document Crunch's customer logos, and customer quotes on both sites (vendor material). Neither tool has been tested by Means & Methods Lab.
