Nonresidential structures

Investment in nonresidential structures consists of new construction (including own-account production), improvements to existing structures, expenditures on new mobile structures, brokers' commissions on sales of structures, and net purchases of used structures by private businesses and by nonprofit institutions from government agencies. New construction includes hotels and motels and mining exploration, shafts, and wells. Nonresidential structures also includes equipment considered to be an integral part of a structure, such as plumbing, heating, and electrical systems.
