The Construction Specifications Institute (CSI) is an individual membership technical society whose core purpose is to improve the process of creating and sustaining the built environment. The Institute provides technical information and products, continuing education, professional conferences, and product shows to enhance communication among all disciplines of nonresidential building design and construction and meet the industry’s need for a common system of organizing and presenting construction information. CSI’s more than 18,000 members include architects, engineers, constructors, specifiers of construction products, suppliers of construction products, building owners, and facilities managers. Founded in 1948, CSI is headquartered outside Washington in Alexandria, VA, and has 143 local chapters nationwide.
