Q.: The engineer on one of our jobs requires that we have a copy of ACI 301, Specifications for Structural Concrete for Buildings, on the job at all times. I can't locate one anywhere in our town. Where can I get a copy?

A.: The only source we know is the American Concrete Institute, Box 19150, Detroit, Michigan 48219. We suggest your company buy them in quantity. The price is quite low that way, and it's a good thing to have one on every job, since ACI 301 is referred to in many job specifications.
