Quantity Surveying (BoQ)
Bill of Quantities (BoQ) in Nigeria: a measured, itemised schedule that makes contractor quotes comparable and stops inflation, for projects in Edo, Lagos, Abuja and nationwide.
Delivered from our Benin City headquarters to clients in Edo State, Lagos, Abuja and across Nigeria, with remote delivery and 24/7 client portal access from anywhere in the world.
What We Do
A Bill of Quantities is the single most effective cost-control document in construction. We price every element of your project, materials, labour, quantities, rates, into a detailed BoQ that contractors tender against and you manage payments with. It is the difference between “the house will cost about ₦25 million” and “this house costs ₦24.7 million, item by item.”
What You Get
- Detailed Bill of Quantities: every element priced: substructure, superstructure, finishes, services

How a BoQ Protects You

Frequently Asked Questions
What is a Bill of Quantities?
A BoQ is a priced schedule of every item of work in your project: materials, labour, quantities and rates. It is the document contractors bid against and the benchmark you use to check their invoices.
How does a BoQ stop contractor inflation?
When every item is priced in advance, contractors cannot inflate vague line items later. Variations become visible and justified, and you pay for what was actually priced: not what a contractor decides to charge.
Do I need a BoQ for a small house build?
Yes. Even a modest build benefits from a BoQ: it turns 'the house will cost about X' into a priced list, lets you compare contractor quotes fairly, and protects you when things change during construction.
How long does a BoQ take?
Typically 1 to 2 weeks from your drawings, depending on project size. Our quantity surveyors work from your architectural and structural drawings to price every element.
Is a Bill of Quantities the same as a construction cost estimate?
No. An estimate is a planning-level budget range by element, used before you commit to a project. A Bill of Quantities is a measured, itemised price list produced from your approved drawings, used to tender and to control payments. The BoQ is the more precise and more useful document once you are choosing a contractor.
