RE: Agenda Item – Execute an Engineering Services Agreement with George Butler
Associates, Inc for Project UT1402 City of Lawrence Flow Monitoring Program.
Please include the following item on the
City Commission agenda for consideration at the March 25, 2014 meeting:
Authorize
the City Manager to Execute an Engineering Services Agreement, in the amount of
$179,595 with George Butler Associates, Inc. (GBA) for Project UT1402 City of
Lawrence Flow Monitoring Program.
Project
Background
The City of Lawrence is implementing a Rapid
Inflow and Infiltration (I/I) Reduction Program. The objective of the Rapid I/I
Program is an overall thirty-five percent (35%) reduction of I/I within the
project area. This will amount to removal of approximately 19 MGD of peak I/I
occurring during the 10-year design storm. Reducing I/I by thirty-five percent
(35%) eliminates the need to construct projects that address system capacity
deficiencies in the Burroughs Creek interceptors and the need for wet weather
treatment capacity expansion at the Kaw WWTP.
The flow data collected as part of this
project will be used to determine the effectiveness of the Rapid I/I Reduction
Program, perform sewer system capacity assessment, characterize flows within
basins, address wet weather problems, calibrate/verify the sanitary sewer model,
and guide I/I removal efforts moving forward.
Project
History
On February 4, 2014, the City Commission
authorized staff to advertise a Request for Proposals for Engineering Services
for the City of Lawrence Flow Monitoring Program.
On February 28, 2014, in response to the
Request for Proposals, staff received proposals from three (3) firms interested
in the project. Proposals were received from ADS Environmental Services, TREKK
Design Group, LLC, and George Butler Associates, Inc. A fourth proposal was received on March 3,
2014 from AMG Environmental Services Inc. This proposal was not considered for
selection since it was received after the due date.
A review committee consisting of staff from the
Utilities Department evaluated the three proposals. At the completion of the proposal
reviews, staff unanimously selected GBA. GBA provided an excellent proposal
that demonstrated an experienced staff committed to perform and manage all
aspects of this project.
Each firm provided a schedule of hourly
rates and a unit price list for equipment rental with their proposal for
reference. The hourly rates and unit prices provided by GBA were found to be
consistent with rates provided by other respondents.
Project
Status
Staff has negotiated an appropriate scope and fee for 2014
flow monitoring services at 20 proposed locations.
The scope for the 2014 project includes:
Flow monitoring services will be required
throughout the eight year Rapid I/I Reduction Program. If the service provided
by the consultant is satisfactory to the City and the consultant is willing,
staff anticipates that a flow monitoring contract will be negotiated each year
with George Butler Associates, Inc. The contract scope will vary yearly adjusting
to the needs of the program.
Project
Funding
The project is included in the Department of
Utilities 2014 operations and maintenance budget and 2013 capital improvement
budget.
Action Request:
Authorize
the City Manager to Execute an Engineering Services Agreement, in the amount of
$179,595 with George Butler Associates, Inc. (GBA) for Project UT1402 City of
Lawrence Flow Monitoring Program.
