Independent Construction Estimating · United Kingdom
PROFESSIONAL ESTIMATING LLC provides dedicated construction estimating, digital quantity takeoffs, and trade-level Builders Quantities exclusively structured around how UK contractors procure, tender, and build.
01 · Methodical Measurement
Rather than relying on rough floor-area rules of thumb, we scale every architectural plan, structural foundation detail, roof pitch, and M&E schematic directly—returning colour-coded PDF verification overlays alongside open-formula Excel bills.
02 · Complete 32-Trade Depth
General estimating packs often stop short on structural steel connections, BS 8666 reinforcement weights, BS 8102 basement tanking, LV containment, HVAC ductwork, and fire sprinklers. Our specialist coverage unites all 32 trades in one consistent format.
03 · Zero Locked Formats
All delivered workbooks remain unlocked so commercial managers and estimators can adjust merchant discounts, gang productivity, prelim durations, and overhead percentages cleanly before submitting bids.
Measurement & Deliverable Parameters
| Estimating Parameter | Technical Specification | Standard / Audit Basis |
|---|---|---|
| Measurement Framework | RICS NRM1 Cost Planning, RICS NRM2 & SMM7 trade conventions | Measured strictly from scaled 1:50 / 1:100 PDF, DWG & IFC drawings |
| Trade Depth | All 32 trades from enabling demolition through M&E sprinklers | Units scheduled in m2, m3, m, kg, t & nr with sheet references |
| Ownership & Wastage | 100% open-formula Excel with 5%–10% typical waste separated cleanly | Never locked in proprietary PDFs—edit merchant & gang rates freely |
| Security & Upload Specs | Up to 25 MB drawing intake · confidential NDA/tender handling | Zero sharing with competing contractors or aggregators |
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.
Yes. We structure bills of quantities to RICS NRM2 work sections (or SMM7 / RIBA Stage elemental NRM1 budgets where requested), ensuring domestic subcontractors, main contractors, and quantity surveyors can audit every measurement against your drawing register.
You receive an open-formula Microsoft Excel workbook (trade summary, line-by-line quantities, waste factors, and notes tabs), colour-coded PDF drawing mark-ups verifying measured zones, and a written RFI / clarification sheet flagging any drawing discrepancies or missing details.
Yes. Many subcontractors come to us exclusively for single-trade takeoffs—such as drylining, roofing, brickwork, structural steelwork, electrical, plumbing, HVAC, groundworks, or concrete rebar—while main contractors often commission multi-trade tender packages.
Yes. Our estimating team measures across domestic extensions, loft conversions, and multi-unit housing right through to commercial Cat A/B office fit-outs, hospitality refurbishments, and steel-framed industrial warehouses across the UK.
