Construction Specification Institute (CSI)

The Construction Specifications Institute (CSI) is a professional organization that develops and maintains standardized language and classifications for construction projects. It helps architects, engineers, contractors, and suppliers communicate clearly by providing organized systems for detailing building materials, products, and systems. This ensures consistency, accuracy, and efficiency throughout the design and construction process, reducing misunderstandings and errors. CSI's most well-known contribution is the MasterFormat, a coding system that categorizes construction information for easy reference and organization. Overall, CSI helps make construction projects more coordinated and manageable through clear documentation standards.
