Planning & EstimatingQuestion 499 of 700

On a foundation inspection, you see anchor bolts set roughly 8 ft apart with the nearest bolt about 20 inches from the end of each sill plate section. Based on typical residential requirements, what is the MOST likely deficiency?

a.Bolts are spaced too closely and there are too many
b.The bolt diameter is the only concern
c.Spacing exceeds the maximum and end bolts are set too far from the plate ends
d.Anchor bolts are not required for wood sill plates

Explanation

Typical residential requirements limit sill-plate anchor bolt spacing to a maximum of about 6 ft on center, with a bolt located within about 12 in of each end of a plate section. Bolts at 8 ft spacing exceed the maximum, and an end bolt 20 in from the end is too far. Options a and d are incorrect; option b overlooks the spacing and end-distance failures that matter most here.
