How is carpentry measured under RICS NRM2?

Keeping carpentry tenders profitable means separating gang-rate first-fix structural carcasses from delicate second-fix FD30/FD60 fire doorset hanging and high-end joinery. We break down every timber dimension, fixing clip, and ironmongery set clearly.

  • Organised by UK site payment stages: Joists/Roofing, 1st Fix Partitions/Grouds, 2nd Fix Doors/Trim, Final Ironmongery.
  • Fire doorsets (FD30S / FD60S) tracked with intumescent strips, drop seals, vision panels, and EN-rated closers.

Which deliverables and drawings are involved?

  • 1st Fix timber & joist takeoff
  • 2nd Fix doorset, skirting & architrave list
  • Staircase, balustrade & kitchen fitting count

Drawings & Inputs Accepted

  • Floor plans & internal elevations
  • Door & ironmongery schedules
  • Staircase & kitchen/joinery details

Work Breakdown & UnitsNRM2 Section 22 & 25 (First & Second Fix Joinery) in m, m2, nr, setsScaled 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.

Carpentry Estimating FAQs

Can you split carpentry into labour-only subcontractor schedules and material supply lists?

Yes. Workbooks split fixings/ironmongery supply counts cleanly alongside per-plot or per-door labour items.

Do you count T&G P5 moisture-resistant flooring chipboard alongside joists?

Yes. P5 structural chipboard/OSB floor decking, D4 adhesive, noggins, and acoustic resilience bars are quantified cleanly.

Can you schedule bespoke built-in wardrobes, window boards, and panelling?

Yes—internal joinery elevations are broken down by MDF/hardwood sheet area, lipping, hinges, and scribed installation.
