ABOUT THE EDITOR
Robert T. Ratay, Ph.D., P.E., is a structural engineer in private practice in
New York with nearly 50 years of design, construction, and teaching experi-
ence, and an Adjunct Professor at Columbia University. His current practice
and teaching are focused on the investigation and litigation support of structural
and construction failures. Dr. Ratay has been an expert consultant/witness for
engineers, contractors, owners, attorneys, and insurance companies in the
investigation and litigation support of nearly 100 cases of temporary structure
and other construction failures. Earlier in his career, he had worked with such
prominent engineering firms as Le Messurier Associates, Severud Associates,
and HNTB, and had been Professor and Chairman of the Civil Engineering
Department, then Dean of the School of Engineering at Pratt Institute, and
Professor at Polytechnic University (formerly Brooklyn Polytech). Dr. Ratay
has lectured extensively at conferences and seminars in the US and abroad, and
published in US and international journals on temporary structures in construc-
tion and on structural and construction failures. In addition to the three editions
of the Temporary Structures in Construction, he is also the Editor in Chief of
two other books: Structural Condition Assessment and Forensic Structural
Engineering Handbook, Second Edition, published in 2005 and 2010, respec-
tively. Dr. Ratay has served on and chaired several technical committees,
including an advisory committee of the Federal Highway Administration to
tighten regulations for temporary structures. He is the originator of the effort
and chairman of the committee that developed and maintains the SEI/ASCE
37, Design Loads on Structures during Construction Standard. In 2003, he was
named by Engineering News-Record as one of the Top Newsmakers 2003 who
“made a mark in the construction industry”; in 2010, he received the Palotás
Award of the Federation International du Beton from the Hungarian Group of
fib “for his very valuable achievements in the field of structural concrete”; in
2011 he was named by Structural Engineer magazine as one of the Power List
of 10 “individuals who bring progress and passion to the structural engineering
field.” Dr. Ratay is a Life Member and Fellow of the American Society of Civil
Engineers (ASCE), former member of the Board of Governors of its Structural
Engineering Institute (SEI), and a Fellow of the International Association
of Bridge and Structural Engineering (IABSE) where he formed and chairs
the Working Group on Forensic Structural Engineering, and he serves on the
Editorial Advisory Panel of the Forensic Engineering Journal of the British
Institution of Civil Engineers (CE).
