BidLight vs Marengo

Two data center offers that sit at different stages of the same build. Marengo is an engineering firm that uses in-house AI tools to take a data center site from due diligence through feasibility, concept and FEED / permitting design. BidLight is BIM coordination and cost software that runs inside Revit and Navisworks, and its pricing page, written for data center delivery, sells both the platform and managed BIM coordination. Not like-for-like (our reading): Marengo works before a site is committed, while BidLight works once the model is being coordinated, detailed and installed. Vendor pages read Oct 21, 2026; desk research, not tested, no winner.

What it doesBIM coordination and cost management running inside Revit and Navisworks that shows what design changes cost, revision by revision. It versions every export, diffs element by element and pins issues to geometry and owners. Re-read Oct 19, 2026: the homepage says issues attach to Revit elements with an automatic 3D screenshot, are assigned by trade and summarized in a daily 6am digest per user; it adds a BIM coordination schedule with per-task issue counts and health, a quality gate (model health and naming validation, approval queue), contribution tracking with a per-person Problem Solver Index, managed upload of approved models and shop drawings to Procore Documents, and ACC/Forma links, and lists BCF, IFC, BIM360 and API connections. Its cost intelligence matches cost lines to model assemblies for labour, equipment, material and time, using BidLight, 1build, Craftsman and RSMeans price databases or your own. BidLight also sells coordination, modelling (LOD 350-500), layout, shop drawing and as-built services. Its /pricing address now opens a BIM management page written for data center delivery, which says logged issues become training data so BidLight can predict where issues will occur on new projects (vendor description). The homepage does not lead with AI, so we keep the Not AI-first label. Re-checked Oct 20, 2026: the homepage is unchanged in substance (versioned exports with element diffs, 6am issue digest, Revit and Navisworks publishing, Procore delivery, ACC/Forma links). The pricing page still prices BIM management per project and by engagement and now links to separate per-licence plans (see pricing); the Complete licence tier lists AI model-health suggestions. Re-read Oct 21, 2026: the homepage is unchanged in substance (runs inside Revit and Navisworks, every export versioned and diffed element by element, issues by 6am, managed delivery to Procore and links with ACC/Forma, BCF, IFC and BIM360 connections). The BIM management pricing page, written for data center delivery, now walks through a data center electrical BIM process (electrical room layouts against the one-line diagram, overhead conduit and hanger modeling, duct banks, pull calculations and shop drawings from Revit, prefabricated electrical skids and as-built modeling) and lists predictive issue flagging among the features included with every option (vendor statements).An engineering firm rather than a software product: it uses in-house AI tools to speed up data center pre-construction engineering, from site due diligence through feasibility, concept design and FEED / permitting design. The site (read Oct 18, 2026) lists deliverables including a site constraints register, developable-area analysis, utility and infrastructure assessment, test fit, master plan, CAD layouts, electrical architecture and single-line diagrams, cooling, civil and structural concepts, a 3D coordinated model and permit-design documentation. It says designs are reviewed and validated by licensed engineers before delivery, client IP is never used to train models, and the client owns everything Marengo produces. Vendor claims, not verified: design cycles of 5-6 months instead of 10-12, 1,000+ concepts explored in parallel, and feasibility studies in half the time and at half the cost. Y Combinator batch: Summer 2026 (YC company profile). Re-checked Oct 19, 2026: the site (rendered in a headless browser) also lists a site risk assessment, a decision-ready feasibility report, basis of design and design criteria among deliverables, an engagement that starts with one site, measured against your conventional workflow, before scaling to more sites, a 6-8 week feasibility timeline versus 12-16 weeks traditional (vendor claim), and Y Combinator, a16z Scout Fund and Index Ventures Scout Fund as backers. Re-checked Oct 20, 2026 (headless browser): unchanged in substance (half-time and half-cost feasibility claims, licensed-engineer review, client IP not used to train models, start with one site); the homepage also shows a 500 MW campus concept of ten buildings at 50 MW facility load each as an illustration. Re-read Oct 21, 2026 (headless browser): the homepage is unchanged in substance (site due diligence, feasibility, concept design and FEED / permitting design; in-house AI tools used by its engineering team; licensed-engineer review; client IP not used to train models; start with one site, benchmark it against your conventional workflow, then scale). Its YC profile now describes it as an AI-native engineering firm automating engineering design, starting with data centers, and also names Exor and Future Planet Capital among its backers (company statements; the revenue and contract figures on that profile are not used).

Pricing (as publicly stated)Re-checked Oct 19, 2026: the per-licence plans we recorded Oct 18 (coordination plans from $30 to $69 per licence per month, Estimation Packages from $279) are no longer on BidLight's pricing page, which now prices BIM management per project: 10-15% of the project's BIM coordination line item, a per-project flat fee of $200K-$600K paid at milestones (campus or multi-building $750K+), or $2.00-$3.50 per square foot of data hall area. Monthly engagements: BidLight Platform $25,000/month ($300K/year; your team runs it); Platform + Oversight $420K/year ($35,000/month on an annual term or $28,000/month on a 3-year term); BidLight Managed $50,000/month ($600K/year; $40,000/month on a 3-year term). Re-checked Oct 20, 2026: the per-project options are unchanged, and the engagement tiers now show 3-year rates for all three (Platform $20,000/month on a 3-year term, alongside $35,000 / $28,000 for Platform + Oversight and $50,000 / $40,000 for Managed). Per-licence plans are back on a separate page (bidlight.com/pricing/software): coordination licences Basics $30, Core $39, Complete $51 and Max $69 (introductory) per licence per month, or $260, $330, $440 and $590 per licence per year billed annually; Estimation Packages Solo $279, Studio $699 and Business $1,399 per licence per month; Enterprise (unlimited licences) on request. Confirm current pricing with the vendor. Re-checked Oct 21, 2026: unchanged. BIM management: 10-15% of the BIM coordination line item, a $200K-$600K per-project flat fee paid at milestones (campus or multi-building $750K+) or $2.00-$3.50 per square foot of data hall area; engagements $25,000, $35,000 and $50,000 a month on annual terms ($20,000, $28,000 and $40,000 on 3-year terms), with staff deployment on the Managed tier charged separately. Per-licence software: Basics $30, Core $39, Complete $51, Max $69 per licence per month ($260, $330, $440, $590 a year); Estimation Packages Solo $279, Studio $699, Business $1,399 per licence per month.No public prices (checked Oct 18, 2026; unchanged Oct 19, 2026): Marengo sells engineering services; the call to action is "Give Us a Site" and marengox.com/pricing returns a not-found page. Confirm with Marengo. Re-checked Oct 20, 2026: still no prices; the call to action is still Give Us a Site.

Where the vendor descriptions differ

  • Where each sits: Marengo's homepage lists four stages (site due diligence, feasibility, concept design, FEED / permitting design) and deliverables including a site constraints register, developable-area analysis, utility and infrastructure assessment, site risk assessment, test fit, master plan, CAD layouts, electrical architecture and single-line diagrams, cooling, civil and structural concepts, a 3D coordinated model, a feasibility report and permit-design documentation. BidLight's data center page walks through electrical room layouts checked against the one-line diagram, overhead conduit and hanger modeling, underground duct banks, pull calculations and shop drawings generated from Revit, prefabricated electrical skids and as-built modeling.
  • Who each is for: Marengo names data center developers and owners evaluating sites; its YC profile calls it an AI-native engineering firm automating engineering design, starting with data centers. BidLight names owners, general contractors and specialty trades (notably electrical subcontractors) doing model coordination, and its pricing page is addressed to GCs and subs delivering data center projects.
  • What you buy: Marengo sells engineering deliverables; it says designs are reviewed and validated by licensed engineers before delivery, client IP is never used to train models and the client owns everything it produces, and it suggests starting with one site and benchmarking the result against your conventional workflow. BidLight sells per-licence software and BIM management engagements (Platform, Platform + Oversight and Managed), and also offers coordination, modelling (LOD 350-500), layout, shop drawing and as-built services. Its coordination features include versioned exports with element-level diffs, issues pinned to model elements, a daily 6am digest, a quality gate and delivery of approved shop drawings to Procore or ACC/Forma.
  • AI (our reading): Marengo says its engineering team uses in-house AI tools to explore design options and run multi-objective optimization; we tag it AI-first. BidLight's homepage does not lead with AI, so we keep the Not AI-first label; its Complete licence tier lists AI model-health suggestions and AI-assisted change reports, and its pricing page says logged issues become training data so it can flag where issues are likely on new projects (predictive issue flagging, vendor description).
  • Pricing (checked Oct 21, 2026): Marengo publishes no prices; marengox.com/pricing returns not-found and the call to action is Give Us a Site. BidLight publishes BIM management pricing per project (10-15% of the BIM coordination line item, a $200K-$600K flat fee paid at milestones with campus or multi-building $750K+, or $2.00-$3.50 per square foot of data hall area) and by engagement ($25,000, $35,000 or $50,000 a month on annual terms; $20,000, $28,000 or $40,000 on 3-year terms; staff deployment on Managed charged separately), plus per-licence plans from $30 to $69 per licence per month and Estimation Packages from $279.
  • Not used here: Marengo's design-cycle, feasibility-time, cost and concepts-explored comparisons and the revenue and contract figures on its YC profile, and BidLight's industry loss, idle-labour, ROI and delivery-time figures, customer logos and quotes (vendor claims). Neither tool has been tested by Means & Methods Lab.

  • Whether Marengo's CAD layouts and 3D coordinated model carry into a Revit model that a BidLight coordination team can use without remodeling
  • What a Marengo due diligence or feasibility engagement costs for one site; it does not publish prices
  • How useful BidLight's predictive issue flagging is on a first project, before your own issue history exists
  • 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?
