Most MEP tools start in the middle. They assume you already know the design constraints and drop you straight into a sizing sheet or a schedule. But the constraints are the whole game, and in practice they live scattered across a brief, an Employer's Requirements document, a contract, and a string of amendments — re-keyed by hand into each tool, slightly differently each time, drifting apart as the job moves. WYRM MEP starts where the job actually starts: with the documents.
Everything runs from a single canvas. The first tab is Project, and it is an intake surface. Drop any project document — a brief, the ERs, the contract, an NEC amendment — and WYRM reads it and extracts the design constraints. The document type is inferred from the file rather than asked for, and the source paragraph is preserved. What comes back is not a summary; it is a structured, locked set of constraints that the rest of the workspace is built on.
A worked example makes the shape concrete. Drop the Employer's Requirements for a Tier IV data-centre expansion and WYRM extracts: the total design IT load, with the clause it came from; the redundancy stance, traced to the concurrent-maintainability requirement; the rack density, from the stated average and peak cabinet loads; the cooling approach; the jurisdiction; the programme date. Each extracted constraint carries a confidence score and a citation to its source paragraph. The IT load pulled verbatim from a clear statement reads high-confidence; a cooling stance assembled from a looser description reads lower, and is flagged for a human to confirm. The spec is auditable from the very first step, because every value points back at the sentence that produced it.
Once that spec is locked, it becomes the single source the rest of the job runs from. The Sizing tab derives facility power from IT load and PUE, mechanical cooling demand, chilled-water flow at the design temperature difference, rack count, white-space footprint, and the cooling-train build-up — every figure from the deterministic engines, with an auditable calc pack behind it. The EPC pipeline runs an SBEM-style build-up with the Part L limits inline and a BRUKL draft export. Compliance screening and the deliverables work from the same locked constraints. Change a parameter on the spec and the downstream tabs recompute against it.
The point of the single-spec architecture is reconciliation by construction. The reason spec, schedule, and drawing drift apart on a traditional job is that each is maintained separately, so a change has to be manually propagated to all three and sometimes is not. When all three derive from one locked spec, they cannot silently disagree — the schedule is computed from the same constraints the spec records, and the drawing is populated from the same source. Reconciliation stops being a checking task you do at the end and becomes a property of how the workspace is built.
The human stays in control of the foundation. Low-confidence extractions are not quietly assumed into the design; they are surfaced for the engineer to confirm or correct before the rest of the job is built on them. This matters because everything downstream inherits the spec — if a constraint is wrong, the error propagates cleanly through sizing and deliverables. Putting the confidence score and the source paragraph in front of the engineer at the lock step is what keeps a fast intake from becoming a fast way to build on a bad assumption.
From the locked spec, the deliverables follow: specifications, schedules, the EPC and compliance outputs, and — on the higher tiers — automatic drawing population back into Revit and AutoCAD using real manufacturer data. The workspace runs the whole arc from brief to issued drawings on one canvas, which is the part that changes how the work feels. The engineer is not stitching together five tools and re-keying constraints between them; they are reviewing and signing a connected job.
The single-canvas workspace is WYRM MEP, one of WYRM's two flagship engineering products alongside WYRM Data, bundled as WYRM Engineering at £250 per seat. The intake-and-lock step is the foundation everything else depends on, which is why it is the first thing you see — get the spec right, with its sources attached, and the rest of the job has something solid to stand on.
