In ordering material from the mill the following items should be 

 borne in mind. Where beams butt at each end against some other 

 member, order the beams ^ inch shorter than the figured lengths ; this 

 will allow a clearance of % inch if all beams come ^ of an inch too 

 long. Where beams are to be built into the wall, order them in full 

 lengths making no allowance for clearance. Order small plates in mul- 

 tiple lengths. Irregular plates on which there will be considerable 

 waste should be ordered cut to templet. Mills will not make reentrant 

 cuts in plates. Allow % of an inch for each milling for members that 

 have to be faced. Order web plates for girders ^ to ^ inch narrower 

 than the distance back to back of angles. Order as nearly as possible 

 every thing cut to required length, except where there is liable to be 

 changes made, in which case order long lengths. 



It is often possible to reduce the cost of mill details by having the 

 mills do only part of the work, the rest being done in the field, or by 

 sending out from the shop to be riveted on in the field connection angles 

 and other small details that would cause the work to take a very much 

 higher price. Standard connections should be used wherever possible, 

 and special work should be avoided. 



The classification of iron and steel bars is given in Table XX VI I. 

 The full extra charges for sizes other than those taking the base rate 

 are seldom enforced ; one-half card extras being very common.
