SPECIFICATIONS x 367 



The amount of carpenter work on the forms is variable, 

 depending on the experience of the carpenters and the 

 intricacy of the work. Usually, a carpenter can erect 

 20 lin. ft. of column form in a day, or 40 sq. ft. of floor and 

 girder form. These figures are for smooth, finished work, 

 and not for rough work.

 acter of the concrete and the steel reinforcement, and the 

 floor load upon which the calculation for the design of the 

 floor system is based.

 columns. 



The contractor is to assume all responsibility for the safety 

 and protection of the work during construction, and shall 

 deliver the same in a complete and finished condition in 

 compliance with the specifications and the accompanying
