Bill of Quantities
Precision Measurement for Accurate Project Pricing
Enhance your tendering process with KJM Ltd's professional Bill of Quantities services. Our meticulously prepared BOQs provide the foundation for accurate pricing, fair comparison of tenders, and effective cost control throughout your construction project.
What Is a Bill of Quantities?
A Bill of Quantities (BOQ) is a comprehensive document that precisely quantifies all materials, labour, and plant required for a construction project. Unlike general specifications or schedules of work, a professionally prepared BOQ breaks down every element into measurable items with standardised descriptions, units, and quantities.
Key Features of Our BOQs:
Detailed measurement of all construction elements
Industry-standard formatting using NRM2/SMM7 conventions
Clear item descriptions and specifications
Accurate quantity calculations
Logical work section organisation
Digital and print-ready formats
The Strategic Advantages of Professional BOQs
For Contractors & Subcontractors
Efficient Pricing Process – Focus on rates rather than quantity take-offs, reducing tendering costs
Reduced Estimating Risk – Rely on professional measurements rather than estimator assumptions
Fair Competition – Compete on efficiency and value rather than quantity interpretation
Clear Scope Definition – Understand precisely what is required with detailed item descriptions
Cash Flow Protection – Use the BOQ as the agreed basis for payment applications
For Project Owners & Developers
Accurate Budget Forecasting – Gain confidence in project viability with precise cost projections
Comparable Tender Returns – Evaluate contractors on a like-for-like basis with standardised pricing documents
Reduced Variation Risk – Minimise unexpected costs with comprehensive scope definition
Simplified Payment Management – Use BOQ as the basis for interim valuations and payment applications
Enhanced Project Control – Track actual vs. budgeted costs throughout the project lifecycle
Levels of Detail to Suit Your Project
Elemental BOQ
Ideal for early-stage cost planning and budget setting, our Elemental BOQs provide quantities organised by building elements (foundations, walls, roofs, etc.), offering a strategic view of cost distribution.
Trade BOQ
Organised by trade (groundworks, brickwork, carpentry, etc.), our Trade BOQs facilitate efficient tendering to specialist contractors and subcontractors while maintaining overall project coordination.
Detailed BOQ
Our comprehensive Detailed BOQs break down every aspect of construction into precisely measured items, providing the ultimate foundation for accurate pricing and cost control.
Activity Schedule BOQ
For NEC contracts and programme-driven projects, our Activity Schedule BOQs align quantities with project activities, enhancing schedule integration and progress monitoring.

Frequently Asked Questions
-
While a Schedule of Works provides a general description of required activities, a Bill of Quantities offers precise measurement of each element. This shifts risk away from contractors (who would otherwise need to estimate quantities themselves) and ensures all tenders are based on identical quantities.
-
Ideally, a BOQ should be prepared when design information is reasonably complete – typically at RIBA Stage 4 (Technical Design). However, we can prepare preliminary BOQs at earlier stages to support budget setting, with appropriate qualifications.
-
Timeframes vary based on project complexity and information availability. For a typical residential project, allow 1-2 weeks; for larger commercial projects, 2-4 weeks is common. We can accommodate urgent requirements through our resource planning.
-
Yes, we offer BOQ revision services to accommodate design developments. Our digital measurement processes make updates efficient, allowing rapid recalculation of affected quantities.
