How is framing measured under RICS NRM2?

Modern UK framing spans traditional hand-cut roofs on loft conversions through off-site timber frame housing cassettes and multi-storey Metsec/SFS infill frames. We count every sole plate, stud, lintel, hip rafter, breather membrane, and galvanised shoe cleanly.

Cut roofs list ridge boards, valleys, hips, rafters, purlins, ceiling joists, and jack rafters by actual pitched slope length + seat cut.
SFS infill packs capture track metres, vertical C-studs at centres, deflection head anchors, and EPDM thermal breaks.

Measurement & Deliverable Parameters

How are UK framing takeoffs structured for tender accuracy?

Framing Estimating — UK Measurement Units, Deliverables & Workflow Specification
Estimating Parameter	Technical Specification	Standard / Audit Basis
Work Breakdown & Units	NRM2 Section 16 & SFS Metal Framing in m, m2, nr	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.

Framing Estimating FAQs

Do cut-roof takeoffs measure sloped hip/valley geometry rather than flat plan projections?

Yes. Slope pitch trigonometry (run x sec(pitch)) and actual hip/valley compound lengths are calculated so timbers are never ordered short.

Do you include galvanized joist hangers, holding-down straps, and birdsmouth fixings?

Yes. Joist hangers, lateral restraint straps, truss clips, and wall-plate holding-down bolts are counted.

Can you measure external cement particle board sheathing (e.g. RCM Y-wall / Fermacell) on SFS?

Yes. Weather-resistant external sheathing boards, taped breather membranes, and vapour-control internal membranes are fully itemised.
