TIMBER TRENDS IN THE UNITED STATES 



board about 20 percent. Although there has 

 been a leveUng off in use of insulation board in 

 recent years, some further increases in use of 

 building board per dwelling unit have been as- 

 sumed over the projection period (table 9 and 

 fig. 11). 



Substantial Rise Projected in Total 

 Use of Lumber and Panel Products 



NEW NONRESIDENTIAL CONSTRUCTION 



(Excluding Farms and Railroads) 



New nonresidential construction, another major 

 market for lumber and panel products, includes 

 industrial, commercial, public, and other buildings; 

 public utilities; sewer and water systems; high- 

 ways; military facilities; and conservation and 

 development projects. The only common unit 

 of measure available for such diverse construction 

 activity is the dollar value of new construction 

 put in place. 



Projections of future use of lumber, derived 

 from the projected levels of construction shown 

 in table 8 and the lumber-use factors developed 

 in table 9, rise from approximately 14 billion 

 board feet in 1962 to an estimated 14.4 billion 

 board feet by 1970 and to 20.6 billion feet by 

 2000 (table 10 and fig. 11). 



Similar calculations for plywood show a rise 

 from 4.2 bilHon square feet in 1962 to 5.2 billion 

 square feet by 1970, and 9.5 bilhon square feet 

 by 2000. 



Use of building board in residential construction 

 is projected from about 1.7 billion square feet 

 (^2-inch basis) in 1962 to 2.0 billion square feet 

 in 1970, and about 4.6 billion square feet in 2000. 



Projected New Nonresidential Construction 

 Expenditures Triple by 2000 



Expenditures for new nonresidential construc- 

 tion have fluctuated rather widely over time (fig. 

 6) , chiefly because of the effects of war and depres- 

 sions. The long-term trend in expenditures has 

 been strongly upward, however, reaching an 

 annual rate of $33.9 biUion in 1962 (table 11)— 

 roughly 2.3 times the average of the 1920's.''' 



'8 Dollar value estimates of construction published by 

 the Department of Commerce include "the cost of archi- 

 tectural and engineering fees, materials and service 

 facilities installed, labor, overhead, and profit on con- 

 struction operations ..." 



Much lumber and plywood is used in Formwork and ofher Faciiitatins roles in nonresidential construction.
