Preparation of Bills of Quantities (BOQ)
Drafting standardized, unambiguous trade bills of quantities formatted under BESMM 4 and RICS NRM2. Forms the contractual pricing baseline for transparent bidding.
MEASUREMENT // COST INTELLIGENCE // COMMERCIAL GOVERNANCE
STANDARD: BESMM 4 • RICS NRM2
QUANTITY SURVEYING & BOQ FROM DESIGN TO COST INTELLIGENCE.
Measure the work. Understand the cost. Control the commercial side of construction. Quantity Surveying transforms technical design models into mathematically verified quantities, structured Bills of Quantities, and commercial governance that prevents budget overruns.
PROJECTION: AXONOMETRIC 3D // STANDARD: BESMM 4 & NRM2

ARCHITECTURAL WALLS // BESMM 4 & NRM2
Internal Blockwork Wall (W1-W40)
225mm hollow sandcrete blockwork laid in 1:4 cement-sand mortar with 15mm smooth plaster on both faces and two coats emulsion paint.

CONCEPTUAL CLARITY & DEFINITIONS
CHOOSE A CORE CONCEPT TO EXPLORE
Select between the foundational definitions of Quantity Surveying, the mechanics of a Bill of Quantities (BOQ), the three commercial pillars, or our core philosophy.
THE 7-STAGE PROGRESSION
FROM TECHNICAL DESIGN TO BOQ
Explore how physical architectural, structural, and building services drawings are converted into legally binding, mathematically audited Bills of Quantities and commercial governance instruments.
THE CENTRAL COMMERCIAL ASSET
THE BOQ IS WHERE DESIGN BECOMES MEASURABLE.
The Bill of Quantities (BOQ) establishes the single contractual source of truth for scope, quantities, unit rates, and total expenditure. Select a trade package below to inspect itemized preambles, units, and rates.
TRADE SCHEDULE
CLASSIFICATION: BESMM 4 BILL 2
BILL NO. 02: SUBSTRUCTURE & PILING WORKS
Site clearance, excavation, continuous flight auger (CFA) piling, reinforced concrete raft foundation, and sub-slab drainage.
| ITEM | DESCRIPTION | UNIT | QUANTITY | RATE (₦) | AMOUNT (₦) |
|---|
NOTICE ON DEMONSTRATION RATES: Unit rates and extensions shown above are illustrative simulated figures calibrated against typical Lagos commercial benchmarks. They do not constitute a live construction cost estimate or quotation for an active Crownate project.
RISK MITIGATION & GOVERNANCE
BEFORE & AFTER QUANTITY SURVEYING
Compare conventional unstructured construction procurement against the commercial discipline and contractual certainty delivered by professional Quantity Surveying.
CAPITAL ALLOCATION
CAPITAL COST PLANNING & WORK BREAKDOWN
How total project capital is distributed across work categories. Select a package below to inspect typical percentage allocations, cost drivers, measurement rules, and procurement strategies.
CAPEX TRADE ALLOCATION
HIGHLIGHT IN 3D ↑
REINFORCED CONCRETE SUPERSTRUCTURE (30% - 38% OF TOTAL COST)
Structural RC columns, post-tensioned suspended slabs, framing downstand beams, elevator core shear walls, and systematic climbing formwork.
COMMERCIAL PARAMETERS & MEASUREMENT GOVERNANCE:
PLANNING GUIDANCE: Trade cost percentages vary based on building typology, geotechnical conditions, finish specifications, and building services intensity.
COMMERCIAL OPTIMIZATION
COST IS NOT JUST A NUMBER.
Value Engineering does not mean “cheapening” a building. It evaluates alternative materials, construction systems, and installation speeds to maximize performance and economic return per Naira invested.
PROCUREMENT GOVERNANCE
TENDER ANALYSIS & BID NORMALIZATION
The lowest tender price is rarely the most economical. Quantity Surveyors audit contractor tender returns to expose front-loading, unbalanced rates, arithmetic errors, and hidden qualifications before contracts are awarded.
EDUCATIONAL SIMULATION
INTERACTIVE QUANTITY × RATE CALCULATOR
Experience the fundamental formula of the Bill of Quantities: QUANTITY × RATE = EXTENDED AMOUNT. Test how alterations in verified take-off dimensions or unit rates affect final trade commitments.
