Subject: Second quote for azimuth bracketry

I just had a call from Mark Goodhart of Goodhart Sons, Inc in Lancaster Pa. He will fax me a quote for $20,500 w/o shipping. Delivery would be 6 to 7 weeks after receipt of order. The basic shop work would need only two weeks but they would have to wait 2 weeks for a punch and then another 2 weeks for galvanizing.

A question for you on tolerances:

Your drawing does not specify tolerances. How about 1 1/16" +1/32" /-0" for the hole diameter/ and slot widths? The smallest radius would then be 17/32". The dimension of 8" between holes would at would have to be specified with a tolerance of at least +/- 1/32". (I think I have this right). And this assumes that the existing hole pairs in the girder all have exactly an 8" spacing. Is this a fact? Were enough rails ties installed initially with 1" bolts to be confident that the 8" spacing is precise? What were the tolerances on diameter and spacing for the rail ties built by RSI. Do you have a copy of RSI's shop drawing?
