How is mechanical measured under RICS NRM2?

Mechanical tenders fail when plantroom headers, commissioning valves, trace heating, and builders’ work Builderswork openings are underestimated. Working from M&E CAD/PDF schematics, we produce structured mechanical bills matching UK B&ES / BESA estimating norms.

Quantifies grooved-joint vs welded steel pipework separately from press-fit copper distribution.
Logs plantroom ancillary items including dosing pots, dirt/air separators, buffer vessels, and pressure gauges.

Measurement & Deliverable Parameters

How are UK mechanical takeoffs structured for tender accuracy?

Mechanical Estimating — UK Measurement Units, Deliverables & Workflow Specification
Estimating Parameter	Technical Specification	Standard / Audit Basis
Work Breakdown & Units	NRM2 Section 38 (Mechanical Engineering Services) in m, nr, item, kW	Scaled PDF / DWG plans at 1:50 & 1:100 (dimensions in mm / m)
Waste & Prelim Separation	Net physical takeoff plus 5%–10% typical trade waste split	Keeps net order counts transparent for merchant tenders
Deliverable Workbook	100% unlocked formula Excel + colour-coded PDF overlays	Includes formal RFI log flagging drawing ambiguities
Turnaround & File Transfer	24–48 hrs (domestic/single trade) · up to 25 MB uploads	3–5 working days typical for multi-trade commercial tenders

Calibration note: 1:50 and 1:100 architectural and structural drawings are scaled to 25 mm masonry tolerances and 100 mm thermal zones, isolating 5 percent to 10 percent wastage from net quantities.

Mechanical Estimating FAQs

Do you measure plantroom insulation cladding (e.g. stucco aluminium or Isogenopak)?

Yes. Exposed plantroom thermal insulation and protective metal/PVC jacketing are isolated alongside standard mineral wool lagging.

Can you extract equipment duties (kW, l/s, head) straight from mechanical schedules?

Yes. Boilers, ASHPs, chillers, circulation pumps, and HIUs carry their exact design duty ratings in our Excel equipment tab.

Are pre-commissioning, chemical flushing, and BSRIA water treatment items included?

Yes—specialist testing, chlorination, flushing, and BMS commissioning allowances are listed in the prelim/testing tab.
