May 6, 2008 Agenda Item – West Baldwin Creek Interceptor Sewer

Set Bid Date - Utilities Department Project #CS0704

 

Please include the following item on the City Commission agenda for consideration at the May 6, 2008 meeting.

 

Set Bid Date for CS0704 - West Baldwin Creek Interceptor Sewer:

Based on the projected timeline of this project, staff requests a bid opening date of June 3, 2008.

 

Project History/Status

The project will construct approximately 15,000 feet of gravity interceptor sewers ranging in size from 10” to 30” identified in the 2003 Wastewater Master Plan as E-BC-1-02, E-BC-2-01 and E-BC-2-02. These extensions also comply with the recommendations of the Northwest Area Update to the 2003 Wastewater Master Plan. The project will connect to and extend the gravity sewers constructed with the Pump Station 48 project and serve the flows in excess of Pump Station 45’s capacity from the BC1 Benefit District. The general area involving the project is shown on the attached map. 

 

The constructed firm capacity of Pump Station 48 is 6.6 MGD.  Currently, only the Free State Interceptor sewer with a design flow of 2.6 MGD connects to Pump Station 48. Upon completion of this project and the direction of the 0.7 MGD from the BC1 Benefit District to PS48; 3.3 MGD of the current PS48 capacity would be available for additional development.

 

Project Timeline

 

July 2007: City entered into a contract with CAS Construction/Professional Engineering Consultants for the preliminary design and submission of a Guaranteed Maximum Price (GMP) for the construction of the project.

 

 November 2007:  A GMP was prepared for the project but staff recommended completing the project as a more traditional design-bid-build project.  (See staff memo discussing design-build GMP) 

 

January 2008:  City entered into a contract with Professional Engineering Consultants for the completion of the design and construction phase services for the project.

 

March 2008:  City authorized use of condemnation for the unsecured easements.

 

April 2008: Professional Engineering Consultants finalized bidding documents, the Court found the City has the authority to condemn for the project and the City Commission adopted Resolution No. 6766 authorizing bonds to be issued for the project.

 

The following schedule is anticipated for the remainder of the project:

May 2008:     Advertise for bids and hold appraiser’s hearing for the two remaining easements.

June 2008:     Award construction contract. (As the bids are in, this item will return to the City Commission on a regular agenda for discussion prior to award.)

April 2009:      Final construction completion.
