BOQ Preparation &
Bill of Quantities Services
Structured, accurate Bills of Quantities prepared from your drawings and specifications by trained quantity surveying specialists. Delivered in tender-ready format, following the measurement standards of your market.
What Is a Bill of Quantities?
A Bill of Quantities (BOQ) is a formal construction document that lists every item of work, material, and associated quantity required to complete a project. It is produced from drawings and specifications and provides contractors with a common basis for pricing, so client comparisons across multiple tenders are consistent.
In markets such as the UK, Ireland, Australia, and New Zealand, the BOQ is often a contractual document. In US and Canadian markets, similar documents are known as quantity takeoffs or schedules of values. efficax.one prepares both to the standard your market and client require.
Our BOQ preparation service handles everything from measurement and item description through to formatted output — so your team can price rather than prepare.
