SPECIFICATIONS 



FOR 



BARNS 

 PLAN NO. 2-A 



These specifications are intended to embrace all 

 material necessary in the erection and completion of the 

 "building in all its parts, and to furnish such instructions 

 as appear necessary to give the builder a general idea of 

 the plan. Variations Hue to different locations and access- 

 ibility of lumber markets have been considered and estimates 

 prepared. 



The general plan as regards construction of frame 

 and other vital parts of the structures is to be followed 

 unless permission to deviate from the plans and specification, 

 has first been secured from the District Forester. Devia- 

 tions of minor consequence, however, to take care of unfore- 

 seen local conditions and circumstances may be made by the 

 builder. 



EXCAVATION. 



Excavation for the foundation of the building 

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

 cavation shall be level and smooth. When necessary to grade 

 into unlevel ground for the purpose of providing a level 

 building site, the slopes of the excavations resulting tfiust 

 clear the sides of the building by at least 3 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. 



FOUNDATION. 



Do not place foundation blocks or underpinning 

 further apart than 7 feet on center. Where snow loads are 

 excessive or the ground is not firm, place foundation blocks 

 or underpinning on 4 foot centers under all outside sills,
