(~ page ~ot~) 8/9/04 Adam Lunsford Project Coordinator This R.F.I. is regards to the 30" force man on the above referenced projeot. We have had an incorrect number of 30" ductile iron bends delivered to the project. Per abe plans, we are shor~ one (1) 225 degree bend and one (1) 45 degree bead. A total of seven (7) 22.5 degree beads were ordered. Due tn the availability of the bends, we are proposing to defle~ the pipe joints from stations 1-20 thru 2*73 and stations 3+09.81 thru 5+36 in order to hit thc required elevations at the bores. If this is acceptable, the 22.5 degree bends at Stations 2+58.09, 2~69.91, 5+05.71, & 5+30.$2 would be deleted, Given this, we would install four (4) of the bends at Stations 2+94, 3+09, 6+09, & 6+39 and would hastall two (2) at Station 6+37.12 in heu ora 45 degree b~ad. We have ddscussed this alternative with the City in the field, and have received their approval if acceptable to the Engineer. If this is acceptable, please let us know as soon a~ possible. Please call me at the offiec once you have reviewed this. Please con£u-m that our plan is acceptable by responding tn this R.,F.I. as soon as possible. Your help is ~reatly appreciated. Les V.
