HEAVY TIMBER MILL CONSTRUCTION BUILDINGS 



Mill Construction Mill construction has always been looked 

 Used to upon with favor for buildings in which ordi- 



Advantage nary manufacturing industries are carried 



on. Warehouses and buildings for storage 

 of merchandise, stores, office buildings, factories, shops, and 

 all buildings of moderate height which are not to be used for 

 extremely hazardous purposes from a fire protection stand- 

 point, are later developments of this type of construction. City 

 building codes limit the height of building and size of open 

 spaces in buildings. They also specify the minimum sizes of 

 timber which shall be used, and other similar details. 



The following extract from the report of G. B. Hegart, 

 Engineer, The Commission of Public Docks, Portland, Ore- 

 gon, for the year ending November 30, 1915, indicates a few 

 of the special advantages of mill construction: 



"The adoption of heavy mill or slow-burning construction in preference 

 to fireproof construction,, was done both on account of the saving in the 

 initial cost and the necessity of taking into consideration the useful or com- 

 mercial life of structures of this character., as it is not at the present time 

 possible to forsee the type of waterfront structures that will be demanded 

 to meet changed requirements twenty-five or thirty years hence, when ex- 

 tensive alterations may have to be made to present structures,, which can be 

 more readily accomplished in timber than in fireproof construction,, or an 

 entire new design may be found necessary to meet the changes in require- 

 ments." 



Mill Construction This bulletin is intended to supplement as 

 and the Architect an educational treatise, and to aid tech- 

 nically, the work of the architect or engi- 

 neer who may not have the time or opportunity to compile 

 such information for himself. While heavy timber mill con- 

 struction buildings are easy to build and have the results of 

 long experience to guide the builder, the services of a competent 

 architect or engineer are always advisable. In no class of 

 buildings can safety and economy of design be more positively 

 assured.
