RE: Agenda Item – Set Proposal Due Date for R1404 - UT1415 Emergency Sanitary Sewer Repair and Authorize Staff to Negotiate with Selected Project Team.

Please include the following item on the City Commission agenda for consideration at the March 25, 2014 meeting:

Authorize staff to set proposal due date for R1404 - UT1415 Emergency Sanitary Sewer Repair and to negotiate with selected project team.

Project Background

In the alley between the 1000 block of New York and Connecticut Street, there is a parallel 48 inch brick storm sewer adjacent to an 8 inch VCP sanitary sewer.  The sewers were constructed in approximately 1932 at similar flow line elevations and with less than 2 feet of horizontal separation.  The City recently discovered sanitary sewer service connections passing through the storm sewer to connect to the sanitary sewer as shown in the attached map. The service connections are broken in the storm sewer causing sanitary flow to discharge into the storm sewer and a cross connection between the two sewers.  It is believed there are 6 houses directly connected to the storm sewer and four cross connection locations. 

Project Description

Staff is proposing to contract with a qualified project team for professional design and construction services to complete the emergency repair.  The project team will include a profession engineer and general contractor qualified to design and construct sanitary and storm sewer public improvements. A time and materials delivery method is requested for this project.  Engineering and construction personnel will collaborate with City staff to develop an agreed upon solution similar to a design build project delivery. Project construction will begin as soon as practical and continue expeditiously until completion.
