Van Milligen, City Mana FROM: Gus Psihoyos, City Engineer SUBJECT: US52 North Storm Sewer Improvement Project (CIP 7201810 &CIP 1001122) DATE: November 21, 2007 INTRODUCTION The enclosed resolution provides for the acceptance of the improvements for the US52 North Storm Sewer Improvement Project. BACKGROUND The US52 North Storm Sewer Improvement Project entailed the replacement of 24-inch diameter storm sewer with a 48-inch diameter storm sewer from the Flexsteel pumping station to US 52 and the replacement of two catch basins located at the low spot (sump) in US52 north of Olympic Heights and south of the Shooting Club drive. With jurisdiction over US52, the Iowa Department of Transportation (Iowa DOT) also had an interest in adequate stormwater drainage of the highway. As a result, the Iowa DOT indicated that the project is eligible for Iowa DOT cost-sharing. DISCUSSION The US52 North Storm Sewer Improvement Project was completed by McClain Excavating Company, Inc. of Peosta, Iowa, in the final contract amount of $178,150.63, which is a 6.1 % decrease from the original contract of $189,712. The primary reason for the decreased project cost is that only 28% of the estimated lime backfill was necessary. This was a savings of $11,490.84. RECOMMENDATION recommend that the City Council accept the improvements and to authorize the payment of the contract amount of $178,150.63 to McClain Excavating Company for the US52 North Storm Sewer Improvement Project.
