Bill of Quantities

A Bill of Quantities is a critical input for cost management, forecasting, and financial control. It translates scope into measurable quantities that can be priced, tracked, and analyzed throughout the project lifecycle. When quantities are inaccurate, incomplete, or poorly structured, cost reporting becomes unreliable and change impacts are difficult to quantify.

This add-on service is commonly engaged when quantity take-offs have not been completed to the level required for effective controls, when costing is based on assumptions rather than measurable data, or when BOQs are disconnected from the project’s cost and reporting systems. We review, validate, or develop BOQs that align with execution scope and project controls requirements.

Our BOQ services are provided on an hourly basis and are typically used to strengthen or correct project setups inherited from early-stage estimates or incomplete documentation.

Why this is required for Project Controls?

• Accurate cost baselines and financial forecasts
• Reliable progress measurement and earned value analysis
• Clear quantification of change orders and variations
• Consistent cost reporting across work packages

What are components of a good BOQ?

• Quantity Take-Off (QTO):
  Measurement of work quantities directly from drawings, specifications, and models to establish accurate scope quantities.
• Costing and Schedule of Rates (SOR) Alignment:
  Mapping quantities to applicable rates, unit costs, and pricing structures to support cost control and reporting.
• Material Take-Off (MTO):
  Identification and quantification of materials required to support procurement planning, cash flow forecasting, and logistics coordination.

What happens to Project Controls without this?

• Cost forecasts rely on assumptions rather than measured quantities
• Change orders cannot be clearly validated or priced
• Progress tracking becomes subjective
• Cash flow projections lack accuracy
• Controls teams must compensate for missing data

What we deliver?

• Review and validation of existing BOQs and take-offs
• Development of structured BOQs aligned with WBS and cost codes
• Correction of quantity inconsistencies or gaps
• Integration of BOQs into cost management and reporting systems
• Preparation of quantity data to support change management and claims

This service is most often used when project teams require stronger quantity definition to support effective cost control or when existing BOQs are not suitable for project controls use.
