Fabrication & Erection Takeoffs · NRM2 Section 15 (Framed & Architectural Metalwork)

UK Structural Steel & Architectural Metalwork Estimating (BS EN 1090)

Member-by-member steel weight schedules (UK BS/EN serial sizes) separating fabrication tonnage, connection plates/bolts, surface treatment (galvanised vs primer vs intumescent), and erection cranes.

How is structural steel measured under RICS NRM2?

Every missed splice plate, stiffening rib, or galvanising dip-tank cost erodes steelwork fabrication margin. Reading straight from structural GA plans and engineer profiles, we build complete steel lists sorted by section profile, steel grade (S275 / S355), length, and total metric tonnage.

  • Uses exact British/European EN 10365 nominal linear weights (kg/m) so metric tonnage reconciles accurately.
  • Separates primary hot-rolled steelwork from cold-rolled purlins/eaves beams and architectural balustrades.

Which deliverables and drawings are involved?

  • Bill of steel sorted by serial profile (UB/UC/SHS/CHS/PFC)
  • Baseplate, endplate & connection allowance schedule
  • Coating m2 (shotblast, zinc primer, HDG) summary

Drawings & Inputs Accepted

  • Structural steel GA plans & grid elevations
  • Connection, baseplate & splice details
  • Secondary metalwork / stair / balustrade drawings

Estimating ParameterTechnical SpecificationStandard / Audit Basis
Work Breakdown & UnitsNRM2 Section 15 (Framed & Architectural Metalwork) in t, kg, m, nrScaled PDF / DWG plans at 1:50 & 1:100 (dimensions in mm / m)
Waste & Prelim SeparationNet physical takeoff plus 5%–10% typical trade waste splitKeeps net order counts transparent for merchant tenders
Deliverable Workbook100% unlocked formula Excel + colour-coded PDF overlaysIncludes formal RFI log flagging drawing ambiguities
Turnaround & File Transfer24–48 hrs (domestic/single trade) · up to 25 MB uploads3–5 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.

Steel Estimating FAQs

Do steel takeoffs account for baseplates, stiffeners, gussets, and bolts?

Yes. Detailed plates are measured directly where drawn, and standard industry connection-plate percentage bands are clearly stated for preliminary engineer issues.

Can you measure secondary architectural metalwork like cat ladders, Juliet balconies, and fire escapes?

Yes. Mild steel stairs, chequer plate landings, KEE-KLAMP/tubular handrails, and structural glass channel balustrades are isolated clearly.

Do you compute surface area (m2) alongside tonnage for off-site intumescent spraying?

Yes—surface perimeter area per tonne is calculated so shotblasting and intumescent quotes match exactly.
