Q.: Where can I get some guidance on estimating reinforcing steel? Sometimes the design details don't make it clear exactly what is required.

A.: The Concrete Reinforcing Steel Institute, 180 North LaSalle Street, Chicago, Illinois 60101 publishes a Manual of Standard Practice that devotes a 4-page chapter to this subject. The 96-page, soft-covered 22nd edition published in 1976, sells for $2.00 per copy.
