SPECIFICATIONS 



FOR 



SECONDARY LOOKOUT 

 14 '0" x 19 '0" 



These specifications are intended to embrace all 

 material necessary in the erection and completion of a 

 building in all its parts, and to furnish such instructions 

 as appear necessary to give the builder a general idea 

 of the plan. Variations due to different locations and 

 accessibility of lumber markets have been considered and 

 estimates prepared accordingly. 



The general plan as regards construction of 

 frame and other vital parts of the structure is to be 

 followed unless permission to deviate from the plans and 

 specifications has first been secured from the District 

 Forester. Deviations of minor consequence, however, 

 to take care of unforeseen local conditions and circum- 

 stances may be made by the builder.

Excavation for the foundation of the building 

 shall be carried down to solid earth. The bottom of the 

 excavation shall be level and smooth, vvhen necessary to 

 grade into un- level ground for the purpose of providing 

 a level building site, the slopes of the excavations 

 resulting must clear the sides of the building by at 

 least three feet. If necessary, provision should be 

 made to prevent earth caving from the embankment from 

 contacting with the sills. If foundation posts are 

 of wood, they too should be protected.
