1 Excludes farm construction. 



2 Includes private commercial buildings such as offices, stores, warehouses, 

 and restaurants. 



3 Includes public and private nonhousekeeping, industrial, educational, 

 religious, hospital and institutional, and similar miscellaneous buildings. 



4 Includes telephone and telegraph, other public utilities, sewer systems, 

 and water supply facilities. 



• Includes military facilities, conservation and development, railroad 

 construction except track construction, and all other public and private 

 construction not included in other categories. 



• Rates of increase calculated from the following 1970 trend values: All 

 classes, $54.9 billion; commercial buildings, $8.3 billion; noncommercial 

 buildings, $22.0 billion; utilities, water and sewer systems, $10.0 billion; 

 highways, $9.0 billion; and all other, $5.6 billion. 



Projections based on those relationships, and 

 the assumed increases in the gross national 

 product, indicate a continuing strong rise in 

 expenditures for new nonresidential construction 

 through the 1970-2000 period but at a declining 

 rate in most classes. The drop in projected growth 

 rates is largest for highways — a reflection of the 

 expectation that the big increases in expenditures 

 in the late 1950's and 1960's associated with 

 funding of the interstate highway system will 

 not be repeated. On the other hand, assumed in- 

 creases in rates of growth in expenditures for utili- 

 ties, and water and sewer systems are based on the 

 expectation that increases will be necessary to 

 maintain or improve the environment. 



Note: Construction expenditures converted to 1967 dollars by U.S. Depart- 

 ment of Agriculture, Forest Service. Annual rates of increase are calculated 

 for 5-year periods from 1920 through 1965, for 1-year periods 1965 through 1970, 

 and for 10-year periods through 2000.

The major part ot the lumber consumed in 

 nonresidential construction in 1970 was used in 

 connection with concrete forming or other facili- 

 tating uses. The remainder went into structural 

 uses such as decking, joists, rafters, beams, and 

 prefabricated trusses and arches. 



Most of the plywood consumed in 1970 also was 

 used for facilitating purposes, primarily for the 

 forming of concrete. The largest part of the build- 

 ing board consumed, was used for structural 

 purposes such as decking, subflooring, and sheathing.
