Agenda Item – Design and Construction Phase Engineering Services for Phase I
of the Kaw Water Treatment Plant Transmission |
Please include the following item on the City Commission
agenda for consideration at the January 29, 2008 meeting:
Authorize the City Manager to execute a contract with Burns
& McDonnell in the amount of $1,131,654.00 for design and construction
phase engineering services for Phase I of the Kaw Water Treatment Plant
Transmission Main and additional services associated with property acquisition
along Phases II & III, and the design and construction of the Kansas River
crossing associated with Phase II.
Project
Description
The 2003 Master Plan identifies several projects for the Kaw Water
Treatment Plant. The projects require
improvements to the water supply facilities (intake system and pumping units) and
the treated water transmission lines leaving the water treatment plant.
Project Details
On January 24, 2006 the City Commission authorized an
Engineering Services Agreement with Burns & McDonnell/Professional
Engineering Consultants for the evaluation of the 2003 Water Master Plan projects identified for the intake, raw
water pumping and finished water transmission mains at the Kaw Water Treatment
Plant.
Based on the results of Professional Engineering
Consultants’ (PEC) evaluation of the treated water transmission main project and
alternative alignments, staff recommend moving forward with the phased design and
construction of the proposed improvements identified as Route A on the attached
exhibit.
These improvements will provide increased ability and reliability for the pumping
of treated water from the Kaw Water Treatment Plant to the southeast area of
On March 6, 2007, staff from PEC and Burns & McDonnell
presented the results of their evaluation and the alternative transmission main
alignments to City Staff during a BusinessLink meeting.
Anticipated Project Budget
2007 Phase I Design $922,000.00
2008 Phase I Construction $6,449,191.00
2008 Phase II Design $952,998.00
2009 Phase II Construction $6,419,262.00
2009 Phase III Design $487,629.00
2010 Phase III Construction $3,403,400.00
Staff anticipate executing a design and construction phase engineering
contract for the Phase I improvements. Contracts for Subsequent Phases would be
negotiated based on satisfactory completion of the prior Phases.
Per the City Commission’s August 28, 2007 authorization staff
advertised a Request for Proposals for design
and construction phase engineering services for Phase I of the Kaw Water
Treatment Plant Transmission Main to the Southeast Lawrence Area.
On October 1, 2007 in response to the Request
for Proposals staff received proposals from three (3) groups interested in the
project. Proposals were received from Bartlett & West/CDM; BG
Consultants/Black & Veatch; and Burns & McDonnell/Professional
Engineering Consultants.
A review committee consisting of Department of Utilities staff
evaluated the three proposals. Staff consistently ranked Burns &
McDonnell/Professional Engineering
Consultants as the highest qualified respondent for the project. As indicated in the RFP the following
criteria were used to rate the responses:
Project knowledge & approach
Key project staff & their experience with similar projects
Location at which the work will be performed
Related experience with the Utilities Department
Schedule to complete the project
Project Status:
Staff have negotiated a contract with Burns & McDonnell for engineering and construction phase services related to Phase I of the Kaw Water Treatment Plant Transmission Main in the amount of $835,450.00. Staff have also negotiated fees in an amount of $296,204.00 for services associated with property acquisition for Phases II & III, and the design and construction phase engineering services for the Kansas River Crossing within Phase II of the transmission main. The total for all services is not to exceed $1,131,654.00.
As part of the evaluation of the above fees Staff have reviewed the engineering design and, where available, construction phase fees for several recent Utilities Department CIP projects. The information is summarized in the table below. While each project listed has its unique challenges and complexities it is apparent that the fees negotiated for this project are within the range, based on the percentage of the construction cost, typical of a project of this type and scope.
Staff recommend proceeding at this time with the additional services for the Phase II Kansas River Crossing and the property acquisition and permitting for Phases II & III. Verification of the alignment and property acquisition for all three (3) phases of the project as part of the Phase I activities provides the City the opportunity to acquire the rights to a continuous corridor for the design and construction of future phases.
Staff also recommend proceeding,
during Phase I, with the design and bidding of the
Project Funding:
Staff have included these recommended improvements and
budget estimates in the latest water rate projections for 2008 through 2011. The
project will be funded with Revenue Bond proceeds as authorized by the City
Commission on October 9, 2007 per Resolution 6743.
Action Request: Authorize
the City Manager to execute a contract with Burns & McDonnell in the amount
of $1,131,654.00 for design and
construction phase engineering services for Phase I of the Kaw Water Treatment
Plant Transmission Main and additional services associated with property
acquisition along Phases II & III, and the design and construction of the
Kansas River crossing associated with Phase II.
Thank you for your assistance. Please advise if you have any questions.
