Planning & EstimatingQuestion 555 of 700
During a pre-pour inspection of a footing formed directly against earth, you check the reinforcing steel. Which condition is MOST important to verify before concrete is placed?
a.That the bars are painted for identification
b.That the bars are tied with the maximum number of ties
c.That the bars touch the soil for a solid bond
d.That the bars have adequate concrete cover and are held off the soil
Explanation
Reinforcing steel must have adequate concrete cover, especially for concrete cast against earth, and must be supported off the soil so concrete fully surrounds it and protects it from corrosion. Option a is irrelevant to structural performance. Option b confuses excess tying with correctness. Option c is a defect: bars touching soil have no cover and will corrode. Confirming cover and support prevents a failed inspection and future spalling.
