What is a Bill of Quantities (BOQ) in Construction?
A Bill of Quantities (BOQ) is an itemized document prepared by a quantity surveyor or cost consultant that details the exact quantities of materials, parts, and labor required to complete a construction project. It translates technical blueprints, structural engineering specifications, and architectural finish schedules into a standardized, line-by-line financial contract document.
In tender processes, a professional Bill of Quantities provides all participating general contractors and subcontractors with a unified basis for pricing. Without a structured BOQ, bidders are forced to perform their own independent takeoffs, resulting in widely erratic bids, scope gaps, and inevitable contractual disputes during construction.
Core Elements Included in Our Bill of Quantities Schedules
Our quantity surveyors assemble complete, tender-ready BOQ workbooks containing the following essential sections:
1. Preliminaries & General Conditions
Site management, temporary utilities, insurances, scaffolding, plant mobilization, health & safety requirements, and testing.
2. Substructure & Earthworks
Site clearing, excavation (bulk and trench), soil compaction, vapor barriers, ground beams, and concrete foundation footings.
3. Superstructure & Framing
Reinforced concrete frames, structural steelwork, floor decking, timber wall framing, and engineered roof trusses.
4. Architectural Enclosure & Finishes
External cladding, masonry, roofing, insulation, windows, doors, drywall, plastering, painting, and floor finishes.
5. MEP & Utility Services
Plumbing fixtures, drainage, HVAC ductwork, electrical power distribution, lighting fixtures, and fire suppression systems.
6. Provisional Sums & Contingencies
Defined and undefined provisional allowances for unforeseen site conditions, specialist sub-contracts, and design development buffers.
Measurement Methods & Standards We Support
We tailor every Bill of Quantities strictly to your regional standard measurement method:
- CSI MasterFormat (16 & 50 Divisions): Standard across the United States and Canada for commercial, residential, and industrial construction.
- CESMM4 (Civil Engineering Standard Method of Measurement): Dedicated to highways, civil sitework, bridges, pipelines, and infrastructure projects.
- NRM1 & NRM2 (New Rules of Measurement): Standard throughout the UK, Middle East, and Commonwealth countries for building works.
- POMI (Principles of Measurement International): Widely used for international development and EPC contracts.
- SMM7: Standard Method of Measurement for legacy building contracts.
