RE: |
Preliminary Agreement for Design/Build
Services for Pump Station 48 – formerly Baldwin Creek 1 Pump Station 1 |
Please include the following item on the City Commission
consent agenda for consideration at the July 11, 2006 meeting:
Enter into a
design/build services contract with the design/build team of CAS Construction/Professional
Engineering Consultants in the amount of $403,000.00 for preliminary design/build
services for the construction of Pump Station 48, its
associated forcemain and a portion of the upstream gravity sewer network in accordance with recommendations in the 2003 Wastewater Master Plan and direction provided by the City
Commission on April 11, 2006.
Summary. Staff has
negotiated a contract for preliminary design/build services with the CAS
Construction/Professional Engineering Consultants design/build team.
After satisfactory completion of the preliminary design/build services the
Utilities Department anticipates amending the contract with the CAS
Construction/Professional Engineering Consultants design/build team, based on a lump sum established
during the preliminary design/build services phase, for final design and
construction of the project.
Project Description. The project
involves the design and construction of the sanitary sewer pump station
identified in the 2003 Wastewater Master Plan as BC1PS1, currently designated
Pump Station 48, its associated forcemain and a portion of the upstream gravity
sewer network. This project was
recommended as part of the adopted 2003 Wastewater Master Plan.
Project
History. Based on the growth
projections used in the 2003 Wastewater Master Plan these
facilities were scheduled to be constructed in 2010. Growth in the area has progressed at a pace
in excess of that identified in the 2003 Wastewater Master Plan. On April 11, 2006 staff presented information
to the City Commission regarding the growth in this area and the need for the
City to accelerate, and participate in, this project. Staff was directed to advertise for proposals
for design/build services to complete the project.
Project Status. On April 13, 2006 the Utilities Department
solicited proposals for design/build services for the design and construction
of Pump Station 48,
its associated forcemain and a portion of the upstream gravity sewer network.
On Monday May 1, 2006, in response to the Request
for Proposals, the Utilities Department Staff received proposals from three design-build
teams. Proposals were received from
Burns & McDonnell/Garney LLC, CDM/Wolf Construction, and CAS
Construction/Professional Engineering Consultants.
A review committee consisting of Department of
Utilities staff evaluated the three proposals. Staff consistently ranked CAS
Construction/Professional Engineering Consultants as the highest qualified team.

Experience with the City of
On May 16, 2006 the City Commission authorized
staff to negotiate a design/build contract with CAS Construction/Professional
Engineering Consultants.
On June 20, 2006 the City Commission authorized
staff to proceed, during the negotiation of the preliminary design/build
services agreement, directly with Professional Engineering Consultants in the
amount of $290,800.00 to perform preliminary field investigative work items
critical to maintaining the current aggressive design/build schedule.
Staff has negotiated the contract for preliminary
design/build services with the CAS Construction/ Professional Engineering
Consultants team as the first part of the project. After satisfactory completion of the
preliminary design/build services phase the Utilities Department anticipates amending
the contract with CAS Construction/Professional Engineering Consultants, based
on a lump sum established during the Preliminary Agreement, for final design
and construction of the project.
Staff anticipates bringing additional project
items to the City Commission for consideration over the next few months regarding
property acquisition and easements, and authorization of a final design/build
contract based on the lump sum generated during the current preliminary
phase.
Project
Funding. Funding for the project will ultimately be
shared by development benefiting from this infrastructure improvement through
the payment of special connection charges and the City-at-large for that
portion of the project that benefits the existing sanitary sewer system.
Action Request. Utilities Department staff requests authorization for the City Manager to enter into a design/build services contract with the CAS Construction/Professional Engineering Consultants team in the amount of $403,000.00 for the preliminary design/build services for Pump Station 48, its associated forcemain and a portion of the upstream gravity sewer network in accordance with recommendations in the 2003 Wastewater Master Plan and as directed by the City Commission on April 11, 2006.
