AGENDA HEADING:

 

Approving and authorizing the execution of Iowa Department of Transportation (IDOT) Change Order No. 18 to Keo Way Phase 2 Storm Sewer Outlet not to exceed City cost of $48,773.00.

 

 

SYNOPSIS:

 

Approval of Change Order No. 18 as prepared by IDOT in the amount not to exceed $48,773.00, for the cost to install a 48-inch manhole over the existing 54-inch brick combined sewer.

 

 

FISCAL IMPACT:

 

Amount:  $48,773.00

 

Funding Source:  2007-2008 CIP, Page Street-23, I-235 Storm and Sanitary Sewer Improvements, STR197, Storm Water Utility Funds.

 

 

ADDITIONAL INFORMATION:

 

On May 22, 2006, under Roll Call No. 06-977, the City Council approved a preconstruction agreement with Iowa DOT for Keo Way (Birds Run) Phase 2 Storm Sewer related to I-235, where the City will reimburse Iowa DOT an estimated 57% of the storm sewer cost, 100% for any enhanced storm capacity, and 100% of sanitary sewer cost.  The repayment will begin in FY 2007-08.  As part of this agreement, change orders exceeding $25,000 in additional City contribution, must be approved by the City Council.

 

Change Order No. 18 is for additional cost to install a 48-inch manhole over the existing 54-inch brick combined sewer at the southwest corner of 8th Street and Keo Way.  The 48-inch manhole will provide access to a bypass structure between the 54-inch brick combined sewer and the 96-inch Birds Run storm sewer.  A concrete block wall would then be constructed in the bypass structure between the 54-inch brick combined sewer and the 96-inch Birds Run storm sewer to permanently block the bypass structure.  The change order has been reviewed by the City’s representative, Veenstra & Kimm, Inc., and found to be reasonable.  The City’s share is 100% because the IDOT will not share in sanitary sewer improvements as part of the agreement.  The work is necessary to eliminate combined sewer overflow as required by the Iowa Department of Natural Resources.  The total change order is for $48,773.
