CSI Construction Documents Technology (CDT) Practice Exam

Division 13 is Special Construction. This division is used for elements that require unique fabrication or nonstandard construction methods that don’t fit the typical divisions. It covers specialized structures or enclosures and other custom-built assemblies that meet specific performance or design criteria. This differs from Specialties, which are common built-in items for operations (like partitions or signage), Site and Infrastructure, which handles site work and external utilities, and Process Equipment, which concerns equipment used in processing facilities. So Division 13 is associated with Special Construction.
