35 ESTIMATE: OF WEIGHT AND COST 



be a fair cost in one case may be sadly in error in another case which 

 appears an exact parallel. The price of labor will be given in each case, 

 or the costs will be based on a charge of 40 cents per hour which in- 

 cludes labor, cost of management, tools, etc. 



Cost of Material. The cost of structural steel can be obtained 

 from the current numbers of the Iron Age, Engineering News, etc., or 

 may be obtained direct from the manufacturers or dealers. In 1903 

 beams, channels, angles, plates, and bars were quoted at about 1.60 

 cents per pound f. o. b. Pittsburg. Beams 18, 20 and 24 inches deep 

 take o.io cents per pound higher price than the base price for beams. 

 The mills at present quote a delivered price only, equal to the mill price 

 plus the usual freight charge. This price is often more than the cus- 

 tomer could obtain by paying the freight himself, on account of the 

 freight rebates that are often allowed. 



Cost of Mill Details. Mills are allowed a variation in length of 

 sections of y^ of an inch ; which means that beams, channels, etc., may 

 come Y% of an inch shorter or ^ of an inch longer than the length 

 called for. When a less variation than this is required a special price 

 is charged for cutting to exact length. The following list of mill ex- 

 tras adopted January, 1902, is now in force :
