Best AI for MEP Design in 2026
Last reviewed: November 2026

MEP teams draw on top of someone else’s design, and that design keeps moving. Every time the architect issues new backgrounds, three disciplines re-lay out receptacles, diffusers, and plumbing fixtures, re-circuit and re-size what moved, and update equipment schedules that live in Excel and on the sheet. Most of that is repeat drafting, and the errors that reach the field are usually small ones: a receptacle on a wall that no longer exists, a diffuser schedule that disagrees with the plan, a water heater tagged on M-201 but missing from P-401.

Rankings

6 tools ranked for mep design

01Our pick

Nomic

AI drafting for power, lighting, mechanical, plumbing, and fire protection drawings, saved as DWGs and checked

Best for: MEP firms that want a new source of drafting capacity for layouts, schedules, background updates, and existing conditions across every discipline on the job

  • Lays out power and lighting plans, receptacle layouts, ductwork, plumbing, and sprinkler layouts from architectural backgrounds, furniture plans, and cutsheets
  • Builds equipment and connection schedules in Excel and draws them on the sheet, on your layers, blocks, and title blocks
  • Turns site walk photos into existing conditions DWGs and survey reports, reading equipment nameplates and panel labels
  • Checks each drawing against the code edition you name, such as NEC, IMC, IPC or UPC, and NFPA 13, and against the source documents, then lists open questions
  • Reads project files in Autodesk Forma, Bentley ProjectWise, Trimble ProjectSight, SharePoint, Egnyte, Fieldwire, Google Drive, Box, Dropbox, Microsoft Teams, Outlook, and Gmail; SOC 2 Type II

Pricing: Free; Individual $20/mo; Business $40/user/mo (25 seat minimum); Enterprise custom

02

MagiCAD

MEP design and calculation modules that run inside Revit, AutoCAD, and BricsCAD

Best for: Mechanical and electrical designers who want sizing and calculations attached to the objects they model

  • Separate Ventilation, Piping, Electrical, Schematics, and Sprinkler Designer modules
  • Calculates pressure drop and loads for mechanical systems, and cable sizing, load balancing, and voltage drop for electrical
  • Large library of manufacturer products through MagiCAD Cloud
  • Runs on both Revit and AutoCAD, so mixed-platform firms keep one toolset

Pricing: Quote based on modules, users, and license model; subscriptions from 3 to 36 months

03

h2x

Browser-based HVAC, plumbing, and fire protection design with live sizing and a new AI Design Assistant

Best for: Mechanical, plumbing, and fire engineers who want layout and calculations in one model, then exported to AutoCAD or Revit

  • Calculates loads and sizes ducts and pipes as the layout changes, with index runs and fan and pump duties
  • Exports a PDF drawing set with your title blocks, AutoCAD files mapped to your layers and blocks, and Revit models
  • The Design Assistant, launched in November 2026, lays out designs from a description while the h2x calculation engine runs the numbers
  • Covers domestic water, drainage, gas, hydronics, and underfloor heating

Pricing: Contact h2x for current pricing

04

Autodesk Revit with Autodesk Assistant

The BIM authoring standard for MEP models, with an AI assistant in tech preview

Best for: MEP teams delivering coordinated Revit models who want help with views, sheets, schedules, and model queries

  • Native duct, pipe, conduit, and electrical circuit modeling with schedules driven by the model
  • Autodesk Assistant in Revit 2027 answers model queries and creates floor plans, sheets, room tags, and PDF exports from prompts
  • A Revit public MCP server, also in tech preview, lets outside AI tools read and act on the model
  • Standard deliverable on coordinated BIM projects

Pricing: US list $3,005/year or $380/month

05

Augmenta

AI electrical raceway routing and clash detection for contractors’ VDC teams

Best for: Electrical contractors modeling conduit and racks for coordination and prefabrication on data centers, hospitals, and other dense projects

  • ACP 2.0 generates clash-free conduit and rack routing from your conduit run schedule and Revit background model
  • Runs clash detection live against duct, pipe, and structure while you steer routes
  • Handles underground and in-slab routing as well as overhead
  • Exports the routed conduit back into Revit

Pricing: Contact Augmenta for pricing

06

ArchiLabs Desktop

An AI agent that edits native content inside Revit and AutoCAD on Windows

Best for: MEP teams that want an agent in their open Revit or AutoCAD session for tagging, schedules, equipment layouts, and parameter updates from spreadsheets

  • Creates and edits native elements, routing, and documentation in the live file
  • Takes PDFs, spreadsheets, annotated screenshots, and narrated screen recordings as instructions
  • Covers both Revit and AutoCAD

Pricing: Desktop from $19/month plus usage credits

Frequently asked questions

Answers to common questions about this comparison.

It depends on the job. For drafting MEP plans, layouts, and schedules as DWGs in your standards with a code check, Nomic. For sizing and calculations attached to the model, MagiCAD in Revit or AutoCAD, or h2x in the browser. For electrical raceway routing on construction projects, Augmenta. For Revit model work, Revit with Autodesk Assistant or ArchiLabs Desktop.

Calculation platforms such as MagiCAD, h2x, and dedicated load calculation software produce the engineering numbers. Nomic drafts and sizes to the criteria and code tables your engineer sets and checks the drawing against code, but it does not run hydraulic, load, or pressure drop analysis. The engineer of record decides.

Yes. Nomic reads the architectural background and furniture plan, lays out receptacles and fixtures, circuits them, and checks spacing against the NEC edition you name, such as the dwelling unit rules in NEC 210.52(A). Your electrical engineer reviews the layout and circuiting before issue.

No. Nomic does not edit Revit models. On Revit projects it delivers DWGs plus a change list that a modeler links into the Revit model, and it can review the drawings and documents the model produces.

Nomic turns site walk photos into existing conditions DWGs and survey reports, reading equipment nameplates and panel labels. Anything it cannot read is listed as an open question so the field team can verify it on the next visit.
