Recommended identity-testing sampling baseline for concrete

Record details

Value

First 400 m³: 1 sample per 100 m³; subsequent volume to 2,500 m³: 1 per 200 m³; above 2,500 m³: 15 samples; bored piles: at least 1 sample per pile

Unit

recommended samples by concrete volume or pile count

Value type

observation

Population

Construction projects performing identity testing for concrete compressive strength

Denominator

BCA common baseline recommendation; QP may require additional sampling for project complexity, critical elements or quality concerns

Notes

Each sample should have at least four cube specimens; the recommendation does not remove QP discretion to require additional tests.

Dates describe this record’s own period and applicability. A verification date does not mean a rule is currently in force.
