standardized structure for organizing sustainable information elements associated with materials, products, systems, and technologies used in construction projects. By using this standardized format, manufacturers are assisted in identifying key product characteristics and providing designers, constructors, and building operators with information needed to help meet sustainable design and operation goals. The identification of the criteria, standards, and applicable certifications using GreenFormat provides designers, constructors, and building operators an effective way to evaluate the sustainable characteristics of materials, products, and processes for selection purposes. GreenFormat arranges sustainable product information into five categories: Product General Information Product Properties Product Life Cycle Manufacturer Sustainability Policies Manufacturer Support Documentation CSI first published GreenFormat in 2009, the most current edition was published in 2015. Uniform Drawing System CSI's Uniform Drawing System is part of the National CAD Standard (NCS), together with the American Institute of Architects (AIA)'s CAD Layer Guidelines. Administered by the National Institute of Building Sciences (NIBS), the NCS coordinates these CAD-related publications to allow consistent and streamlined communication among owners and design/construction teams. CSI Practice Guides The CSI Practice Guide series debuted in 2011. This series replaced the CSI Project Resource Manual (PRM), first published in 2004, and the CSI Manual of Practice (MOP), published from 1967 until 2004. The Practice Guides are best practice references for construction industry professionals. Project Delivery Practice Guide The CSI Project Delivery Practice Guide (PDPG) is the introductory volume in the Practice Guide Series. The PDPG presents an overview of the process needed to conceive, design, construct, and maintain a construction project. This Guide describes the many parts of that process and the inter-related roles of the various participants in the process. The second edition was published by CSI in 2017, and the most current edition, the third edition, was published by CSI in 2020. Construction Specifications Practice Guide The CSI Construction Specifications Practice Guide (CSPG) describes the process needed to effectively communicate a project design from the designer to the contractor and other members of the project team for the process of project conception, design, construction, and operation. The successful communication of a project design depends on the creation of a complete and coordinated set of construction documents both graphical and written. The CSPG serves as a guidebook to the preparation, organization, and coordination of construction documents and focuses on the written description of a project and how that description relates to the other construction documents,
