• The Foundation published Tolerances for Cast-in-Place Concrete Buildings, A Guide for Specifiers, Contractors and Inspectors, written by Bruce A. Suprenant, PhD, PE, FACI, and Ward R. Malisch, PhD, PE, FACI.  The book suggests practical tolerances based on as-built measurements on buildings that have performed satisfactorily.  It includes a history of CIP tolerances, as-built data and rational tolerances based on practical observations. The book's statement of purpose reads as follows:  "This book was published to make tolerances more easily understood by the construction team and to minimize any misunderstanding of how tolerances are to be used in practice." From Concrete Construction Magazine:  "Authors Malisch and Suprenant have culled relevant information from more than a hundred diverse sources including published standards, books, committee reports, magazine articles, and research reports.  By researching ACI archives and other historical documents, the authors have provided both valuable perspective and interesting reading.  It's quite impressive to see how much knowledge has been brought together in this single publication from so many disparate sources.  By consolidating it into one volume and including the benefit of their collective experience and expertise, they have put together a worthwhile reference work for the concrete industry."
