Mini BOQ Builder – Bill of Quantities & Cost Estimate
Use the mini boq builder calculator to perform a quick preliminary calculation from project dimensions and engineering assumptions. Review inputs and verify final results against project requirements.
Introduction
Build a preliminary Bill of Quantities by organizing construction items, quantities, units and rates into a structured cost summary.
What Is a BOQ?
A Bill of Quantities is a structured list of measurable work items used for estimating, tendering, procurement and cost control. A good BOQ defines the item, unit, quantity and applicable rate.
How to Build a BOQ
Break the project into work sections such as earthwork, concrete, reinforcement, masonry, plaster, flooring, painting and services. Measure each item from drawings, assign units and apply current rates.
Quantity vs Rate
Quantity comes from measurement; rate represents the cost per unit. Keeping them separate makes it easier to update market prices without changing the measured quantities.
Common BOQ Errors
Watch for missing items, duplicate quantities, inconsistent units, unmeasured openings, incorrect wastage and rates that mix material-only and labour-inclusive scopes.
FAQs
Q: Is a BOQ the same as a cost estimate? A: A BOQ is a structured quantity document; an estimate uses quantities and rates to calculate cost.
Q: Can this tool create a tender-ready BOQ? A: It is a mini planning tool and should be checked against drawings and contract requirements.
Disclaimer
Final tender BOQs should be prepared and verified from approved drawings, specifications and measurement rules.
