Lowering of 8" Water Main at Station 10+10 Rex Street. <br /> Based on grist information we received from the City, <br /> for design purposes, this was a 4 Water Main at this <br /> location. Consequently we had to lower the main which <br /> increased the trench length for lowering purposes. Refer <br /> to cost per C. 0. S 1, Part II. Additional costs as follows: <br /> a. Pavement Removal , Item 4: <br /> (5' x 18') ■ 10 s. y. x $5.00 $ 50.00 <br /> b. Instructed Contractor to backfill trench with <br /> Class 6 base material for public traffic <br /> convenience purposes. Trench depth and average <br /> 6 feet. Thus: <br /> (5'x17'x6' deep) = 34.5 tons x $45.00 - $ 1,552.00 <br /> c. H.B.A. Patching - Gr. 'E' , Item 18: <br /> (5'x18'x3" thick) = 1 .7 ton x $66.00 $ 112.00 <br /> d.

Lowering of 8" Water Main at Station 16+ 54 Rex Street. <br /> The storm sewer was designed with 0'3" of clearance <br /> between Storm Sewer 0. D. and 8" Water Main 0. D. . During <br /> construction the 8" Water Main was higher than anticipated <br /> by elevations taken at existing gate valves at the 8" water <br /> line. We could not raise the storm sewer due to minimum <br /> cover requirements of the storm sewer. Thusly we instructed <br /> the Contractor to lower the 6" Water line in this area. <br /> Additional costs are as follows: <br /> a. Pavement Removal , Item 4: <br /> (5'x28') - 15.5 s.y. x S5.00 * $ 77.00 <br /> b. Class 6 Base, Item 17: <br /> (51x28')6" depth) = 4.7 ton x $45.00 $ 211 .00 <br /> c. N.B.P. Patching - Gr.
