Belidor vs MeltPlan

Two AI preconstruction tools that both generate trade scopes from plans and specs, with different reach (our reading). Belidor focuses on scope generation: it turns a drawing and spec set into cited trade bid packages and flags drawing-versus-spec conflicts as potential RFIs. MeltPlan is a broader preconstruction platform for general contractors, with Melt Bid (scope generation and sub bid leveling), Melt Review (document review), Melt Takeoff and Melt Code. Desk research from vendor pages read Oct 24, 2026; not tested, no winner.

What it doesScope generation for estimating teams: upload plans and specs to create trade bid packages, with conflicts flagged as potential RFIs. The vendor says drawing-versus-spec conflicts cite both sources, every scope line is cited to its drawing or spec page, packages push to BuildingConnected or export to Excel, PDF or Word, and inputs can be PDF (including scans) or DOCX. Vendor states SOC 2 Type I and II and says documents are processed under terms that exclude training on customer data. Vendor says ~40+ hours of manual scoping per bid becomes about an hour (vendor claim). Re-checked Oct 19, 2026: the FAQ says it works on construction document and design development sets (a schematic set returns thinner scope, with more lines flagged rather than cited), runs in the browser, does not do markup but reads the markups and clouds in a set, and uses large language models with its own engineering around them; during a pilot a Belidor estimator checks how the scope is organized. Sets are encrypted in transit and at rest on US servers and deleted when the project is deleted or on request, and the security report is sent under NDA (vendor statements). Re-checked Oct 20, 2026: homepage and FAQ unchanged in substance (PDF sets including scans and DOCX in; push to BuildingConnected or export to Excel, PDF or Word out; every scope line cited to a drawing or spec page; SOC 2 Type I and II; the FAQ puts processing at under an hour and upload-to-export at two hours or less, vendor statements). Re-checked Oct 22, 2026 (rendered homepage; a plain fetch was rate-limited): unchanged in substance (PDF sets including scans and DOCX in; every scope line cited to a drawing or spec page; drawing-versus-spec conflicts flagged with both sources; push to BuildingConnected or export to Excel, PDF or Word; browser based; a Belidor estimator checks scope organization during a pilot; SOC 2 Type I and II; US servers; no training on customer data). The homepage now adds a customer story and a table contrasting Belidor with generic AI tools. Time-saved, missed-scope cost figures and customer quotes are vendor material and not used. Re-checked Oct 24, 2026 (rendered homepage; a plain fetch was rate-limited): unchanged in substance (PDF sets including scans and DOCX in; every scope line cited; drawing-versus-spec conflicts flagged with both sources; push to BuildingConnected or export to Excel, PDF or Word; browser based; a Belidor estimator checks scope organization during a pilot; SOC 2 Type I and II; US servers; no training on customer data; documents deleted when the project is deleted or on request). The homepage adds a second customer story; customer quotes and figures are not used.AI-first preconstruction platform for GCs, from concept to GMP: document review, quantity takeoff, scope sheets, bid leveling and code research. Products are Melt Bid (scoping, tabulation and leveling into your own bid tally template, in a web app or Excel plugin, with every value linked to its source proposal), Melt Review (document review and precon reports on hidden costs), Melt Takeoff (AI quantities reviewed by experienced estimators) and Melt Code; its FAQ also names Melt Schedule. It names integrations with Google Workspace, Microsoft 365, SharePoint, Box and BuildingConnected, and says customer data is never used to train models. Vendor claims 10x precon output and 95%+ accuracy (vendor claims). Re-checked Oct 19, 2026: unchanged in substance. The site adds a For Developers solution page and lists cost benchmarks among its workflows; its FAQ says Melt Bid reads sub proposals as PDFs, Word files, Excel sheets or emails, most teams start with Melt Bid or Melt Review, and it covers commercial, healthcare, residential and industrial work. On data, it says bid data and cost history are never used to train its or third-party models (stated as contractually guaranteed), each organization's data is isolated and encrypted, and a customer that leaves gets a full export and written confirmation that everything, backups included, was deleted (vendor statements). Customer quotes with hours-saved figures are vendor-published and not used here. Re-checked Oct 21, 2026: the navigation lists Melt Bid, Melt Review, Melt Takeoff and Melt Code; the data statements above are unchanged. Re-checked Oct 22, 2026: homepage unchanged in substance (Melt Bid, Melt Review, Melt Takeoff and Melt Code in the product list, Melt Schedule in the FAQ; quantity takeoffs reviewed by estimators; the same data isolation, no-training and export-on-exit statements). The 10x, 95%+ accuracy and hours-saved lines and customer quotes remain vendor material and are not used.

Pricing (as publicly stated)No public prices found (re-checked Oct 17 and Oct 19, 2026): the vendor's FAQ says plans are priced per organization, with no limit on the number of projects or the size of the documents, and that the numbers are covered on a demo call; there is no pricing or plans page (/pricing returned a not-found page on Oct 16). The site's calls to action are "Book a demo" and "Get started". Confirm current pricing with the vendor. Re-checked Oct 20, 2026: unchanged; /pricing still returns a not-found page and the FAQ still says plans are priced per organization with no limit on projects or document size, with the numbers covered on the demo call. Re-checked Oct 22, 2026: unchanged (the FAQ still says plans are priced per organization with no limit on projects or document size, with the numbers covered on the demo call; no pricing page). Re-checked Oct 24, 2026: unchanged (no pricing page; plans priced per organization with no limit on projects or document size, with the numbers covered on the demo call).Custom quote / no public prices on pricing page (re-checked Oct 17, 2026). The page says MeltPlan prices on the square footage run through the platform, with a per-square-foot rate that drops at set volume tiers, unlimited users, projects and storage, dedicated onboarding, and bundle pricing across product lines; no rates are shown. Re-checked Oct 19, 2026: still no rates; the FAQ says usage is the square footage of everything you pursue and win, tracked automatically from uploaded plans and specs, with the rate set on actual volume each billing period. Re-checked Oct 21, 2026: still no rates; the page still prices on square footage pursued and won, with unlimited users, projects and storage and dedicated onboarding, and says the rate drops with more volume and with more MeltPlan workflows. Re-checked Oct 22, 2026: still no rates. The quote form now asks for company type (general contractor, specialty contractor, owner/developer, government or architecture firm) and annual construction volume in bands from $0-5M to $100M+; pricing is still on square footage pursued and won, with unlimited seats, projects and storage.

Where the vendor descriptions differ

  • Scope generation (vendor pages): Belidor says it reads PDF sets (including scans) and DOCX, cites every scope line to its drawing or spec page, flags conflicts with both sources cited, and pushes packages to BuildingConnected or exports to Excel, PDF or Word. MeltPlan's Melt Bid generates scopes from plans and specs and builds bid packages from your documents.
  • After the scope: Belidor's pages stop at scope packages and conflicts. Melt Bid also levels subcontractor proposals in any format subs send (PDF, Word, Excel or email) into your own tally template, in the web app or an Excel add-in, links every value to its source proposal, flags low-confidence values, and can plug gaps with average, median or maximum figures and draft clarification emails.
  • Wider platform: MeltPlan also lists Melt Review (design changes, inconsistencies and missing requirements in plans and specs, with precon reports on items like sole-source products, testing and mockups), Melt Takeoff (quantities from plans checked by its estimators) and Melt Code (building code research). Belidor does not describe takeoff or bid leveling on the pages we read.
  • Human checks and data: during a pilot a Belidor estimator checks how scope is organized; Belidor states SOC 2 Type I and II, US servers and no training on customer data. MeltPlan says Melt Takeoff quantities are reviewed by experienced estimators, data is isolated per organization, encrypted and never used to train AI models, with a full export and deletion if you leave.
  • Connections: both name BuildingConnected. MeltPlan also lists Google Workspace, Microsoft 365, SharePoint, Box and an Excel plugin.
  • Pricing (checked Oct 24, 2026): neither publishes figures. Belidor's FAQ says plans are priced per organization with no limit on projects or document size, with numbers on a demo call. MeltPlan prices on the square footage you run through it, with unlimited seats, a rate that drops as volume grows and bundle pricing across products, via a custom quote.
  • Not used here: both vendors' accuracy, time-saved and missed-scope figures and customer quotes. Neither tool has been tested by Means & Methods Lab.

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • What each costs for your annual bid volume (per organization versus per square foot)
  • Whether you need scope packages only or scope plus bid leveling, review and takeoff in one platform
  • How each handles schematic or partial document sets on your projects
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
