What is agentic MEP?
Agentic MEP is mechanical, electrical and plumbing engineering run by a coordinated studio of AI agents. The agents plan, draft and coordinate; an integral suite of rule-based calculation engines does the maths; a named engineer signs. It is the engineering model behind WYRM MEP.
Definition
Agentic MEP, defined.
The term is new, so here is a clean one. Agentic MEP separates two things that an AI copilot blurs together: the language of engineering and the engineering itself.
WYRM brings this approach into one engineering package, using a custom AI model built specifically for building services. It calculates and sizes the services through deterministic engines, draws the resulting layouts and coordinates them across the building. Manufacturer data informs equipment selection, performance and spatial requirements. The design then feeds Revit updates, specifications, schedules and reports, reducing reliance on separate applications and repeated transfers of project information.
How agentic MEP works
A studio of agents over an integral calculation suite.
Three layers. The agents coordinate, the engines compute, the engineer signs, and the boundary between language and maths is never crossed.
The agent studio
A structured team of specialised agents, specification, scheduling, cross-discipline coordination, QA, orchestrates the job the way a design office runs it. They read the brief, plan the work, draft, and walk every change across disciplines. This is the language-and-coordination layer.
The integral calculation suite
Underneath sits a suite of deterministic, rule-based calculation engines bound to the standards. Every number, every cable, duct, plant item, airflow, temperature, is computed here, never by a language model. Same inputs, same answer, every time, with the working shown.
The QA firewall + the named engineer
Two deterministic QA gates check the join before anything is issued; anything unverified stays a draft and nothing remains signed once its basis moves. Then a qualified engineer reviews and signs. Agentic MEP is advisory; the engineer is the authority.
Agentic MEP vs the alternatives
Not a copilot. Not a spreadsheet.
An AI copilot puts a language model in the calculation loop. Traditional MEP puts all the load on the engineer. Agentic MEP does neither.
| Traditional MEP | AI copilot | Agentic MEP (WYRM) | |
|---|---|---|---|
| Who does the maths | Engineer, by hand + spreadsheets | A language model, can hallucinate | Deterministic rule-based engines |
| Coordination | Manual, across tools and people | One assistant in one tool | A studio of agents, end to end |
| Repeatability | Varies by engineer + time pressure | Non-deterministic outputs | Same inputs → same result, cited |
| Auditability | Depends on the paper trail | Opaque model reasoning | Every figure traced to a standard |
| Authority | The engineer signs | Unclear, output looks finished | Advisory only; named engineer signs |
Across the building services
Engineering in every room.
WYRM calculates, sizes and draws the services across disciplines. The same engineering information feeds equipment selection, coordination and the project documents.

Agentic MEP, FAQ
The questions people ask about agentic MEP.
What is agentic MEP?
Agentic MEP is mechanical, electrical and plumbing engineering run by a coordinated team of AI agents rather than a single chatbot or copilot. The agents plan the job, draft specifications, build schedules and coordinate across disciplines like a design office, but they never do the engineering maths themselves. Every calculation is handed to an integral suite of deterministic, rule-based calculation engines tied to the standards, so the engineering is computed and cited rather than generated by a language model. A qualified engineer reviews and signs every output. WYRM MEP is an implementation of agentic MEP engineering.
How is agentic MEP different from an AI copilot for MEP?
An AI copilot is a single assistant that answers prompts inside one tool and will, if asked, attempt the calculation itself with a language model, which can hallucinate. Agentic MEP is a structured studio of specialised agents that own different parts of the job (specification, scheduling, coordination, QA) and orchestrate the work end to end, while every engineering calculation is delegated to a separate, deterministic rule-based engine. The agents handle language and coordination; they are never allowed to size a cable, a duct or a plant item. That separation is what makes agentic MEP auditable.
Does agentic MEP replace MEP engineers?
No. Agentic MEP removes the repetitive drafting, scheduling and cross-discipline coordination that consumes an engineer's day, and returns a computed, cited output for the engineer to review. The qualified engineer remains the authority: nothing is issued until a named engineer has checked and signed it. Agentic MEP is advisory, never authority, it gives engineers their time back, it does not take their responsibility away.
Can agentic MEP hallucinate engineering calculations?
Agentic MEP is designed specifically to prevent this. Language models only read, plan, draft and coordinate inside tight, grounded prompts; they are structurally prevented from performing engineering calculations. The calculations run on deterministic rule-based logic trees tied to the standards (BS 7671, CIBSE, Approved Documents, SBEM / BRUKL), so the same inputs always return the same result and every figure traces to the standard and the line of working behind it. Deterministic QA gates check each output before a named engineer signs.
What disciplines and standards does agentic MEP cover?
Agentic MEP connects mechanical, electrical and plumbing design work. WYRM's pilot includes document production, live Revit model updates, thermal modelling, specification writing, schedule creation and Drawing Studio. Passivhaus and PHPP workflows connect building performance with the services design, while COBie connects asset information with handover. Discuss the calculation methods and project requirements with the team when defining your pilot.
Is agentic MEP the same as WYRM MEP?
WYRM MEP is a product built on the agentic MEP model. It pairs a studio of coordinating agents with an integral suite of rule-based calculation engines and two QA gates, and a named engineer signs every output. Agentic MEP is the engineering approach; WYRM MEP is the software that delivers it. WYRM MEP starts at £20/seat for the Advisor, £150/seat for the full product with metered drawing automation, and £250/seat bundled with WYRM Data.
