During the progress of night work it is necessary to 

 be extremely careful to see that the work is carried on 

 in exact accordance with the specifications. No night 

 work will be permitted unless proper arrangements are 

 made for the lighting of the work. 



Records. The date upon which each portion of the 

 work is completed must be marked in ink upon the 

 plans. This entry must not be neglected, it must be 

 made each day immediately after the completion of 

 the work. 



Test Pieces. A test cube, in the case of slabs 6x6x6 

 in. and in the case of beams 12x12x12 in. must be made 

 each day. Each cube must be dated. These cubes will 

 be poured in boxes and will be used to approximately 

 determine the condition of the work before the center- 

 ing is removed. Care must be used to see that each 

 cube is exposed to conditions approximating the ex- 

 posure of the portion of the work to which it refers. 



Cement Finish. When the cement finish is less than 

 3 in. thick it must be deposited, practically simulta- 

 neously with the concrete. The finish must conform to 

 the specifications and the drawings. 



Cutting out Concrete. Cutting holes in the con- 

 crete will not be permitted except by the pernii-sin in 

 writing of the engineer. The location of each cut must 

 be clearly indicated. Beams must not be cut under 

 any consideration. 



Caution. The engineer or his duly authorized rep- 

 resentative, alone have any authority to give directions 

 in regard to the work. Any directions involving the 

 slightest departure from the plans or specification or 

 from both must be given in writing. Particular care 

 must be used to follow this direction. No man upon 

 the work is to be permitted to receive any orders what- 

 soever, except from those placed directly in authority 

 over him.
