Telephone <br />Ptymouth. MN <br />55447 <br />October 13, 1988 <br />612/476 -6010 <br />Engineers <br />Planners <br />Surveyors <br />As requested, we have reviewed the oversizing of watermain associated with <br />the subject project. <br />As you are aware, the original watermain plan had an internal 6 inch main <br />that was looped between the future office building and the present Gardner <br />Bros. office building. As a result of the final plan preparation and review, <br />it was determined that the most economical watermain design for your office <br />park and the City's truck watermain was to loop the watermain in the Desota <br />Avenue right of way. This option entailed the construction of additional 6 <br />inch watermain in the office park and a 10 inch watermain in Desota Avenue. <br />The cost of the oversizing of watermain amounts to $7,452.50 and has been <br />itemized below: <br />Original Option <br />6" DIP CL. 53 <br />6" Wet Tap w/ <br />6" Gate Valve <br />6" Gate Valves <br />Approved Option <br />10" DIP CL. 52 <br />6" DIP CL. 53 <br />8" Wet Tap W/ <br />8" Gate Valve <br />6" Wet Tap w/ <br />6" Gate Valve <br />6" Gate Valve <br />1,180 L.F. 7 $ 13.50/LF = $15,930.00 <br />2 E.A. 1 $1,500.00 /EA = 3,000.00 <br />5 E.A. $ 400.00 /EA = 2,000.00 <br />Total $20,930.00 <br />430 L.F. $ 18.00 /LF = $ 7,740.00 <br />1,055 L.F. ® 13.50 /LF = 14,242.50 <br />1 E.A. 2 1,800.00 /EA = 1,800.00 <br />2 E.A. r 1,500.00 /EA = 3,000.00 <br />4 E.A. 1 400.00 /EA = 1,600.00 <br />Total $28,382.50 <br />Oversizing Cost: $28,382.50 - 20,930.00 = $7,452.50 <br />PAGE -7- <br />An Eoui Opportunity Employer <br />
