Introduction
A Bill of Quantities (BOQ) is far more than a list of materials. For cladding contractors, it serves as the commercial backbone of every tender, providing a structured breakdown of materials, labour, and installation requirements.
A well-prepared BOQ improves pricing accuracy, simplifies procurement, and reduces commercial risk throughout the project lifecycle.
What Is a BOQ?
A BOQ is a detailed document that quantifies every measurable element within a construction package.
For facade projects, it typically includes:
Panel quantities
Support systems
Brackets
Rails
Insulation
Fire barriers
Membranes
Flashings
Copings
Fixings
Sealants
Labour allowances
Why BOQs Matter
A structured BOQ helps contractors:
Price projects consistently
Compare supplier quotations
Monitor procurement
Track cost variations
Reduce omissions
Improve tender quality
Without a BOQ, estimating often relies on assumptions rather than measurable quantities.
