Why a Good BoQ Matters
A project is unlikely to be successful without a strong BoQ that is stress-tested, and could be the one thing holding you back from a commercially successful project.
-
Reduces disputes
BoQ errors drive 30–40% of construction disputes and can push costs up by 25%. One avoided dispute can return multiples of the BoQ fee.
​
-
Prevent cost overruns
Pricing the full scope upfront means more visibility on your costs right from the start.
​
-
Compare tenders accurately
’Apples-to-apples’ across packages.
​
-
Improve cash flow & planning
Reliable quantities feeding budgets, CVRs and procurement.
​
-
Risk allowances
Construction projects often face unforeseen risks, from material price increases to project delays. Failing to include contingency allowances in the BoQ can leave the project financially unprepared for unexpected costs.
​
-
Unaccounted-for items
Missing, inaccurate items and work elements represent one of the most significant risks to construction project control and successful delivery
​
-
Used by the industry’s best
The top contractors use BoQs because they know clarity, consistency, and control are what keep projects on track. There’s a reason the best are the best.
