Agenda Item – Authorize the City Manager to execute an Engineering Services
Agreement with Professional Engineering Consultants for Design Phase
Engineering Services for project UT1312DS, Bob Billings Parkway Watermain
Replacement George Williams Way to Bobwhite Drive. |
Please include the following item on the
City Commission Agenda for consideration at the January 28, 2014 meeting:
Authorize
the City Manager to execute an engineering services agreement with Professional
Engineering Consultants for design phase engineering services in the amount of
$49,457.00 for project UT1312DS, Bob Billings Parkway
Watermain Replacement George Williams Way to Bobwhite Drive.
Project
Description:
Staff anticipates the ongoing need for the
relocation and replacement of water distribution infrastructure due to
conflicts with proposed street improvement projects, pipe age, reliability,
water quality and capacity issues. The previous five (5) years, 2009-2013, the program targeted the
replacement of over 17,000 feet of 8” and 12” watermains along Iowa Street from
9th to University, Orchard Lane from Centennial to Iowa, Kentucky
Street from 12th to 19th Streets, 9th Street
from Vermont to Tennessee, 18th Street from Tennessee to Kentucky, 13th
Street from Tennessee to Vermont, Bob Billings Parkway from Iowa Street to
Kasold Drive, and 19th Street from Maple Lane to Harper Street.
Department Staff also self performed several smaller watermain replacements
during this period.
Project
History:
On October 8, 2013, City Commission authorized staff to advertise a
Request for Proposals for Design and Construction Phase Engineering Services.
On November 8, 2013, staff received proposals from six (6) groups.
Proposals were received from Benesch Engineers, BG Consultants, CFS Engineers,
HDR Engineering, Professional Engineering Consultants, and Wilson & Company
Architects and Engineers. Review committee staff evaluated the proposals and
determined Professional Engineering Consultants to be the highest qualified
respondent for the requested services.
On December 17, 2013, City Commission authorized staff to negotiate an
engineering services agreement with Professional Engineering Consultants.
Project
Details:
Staff identified the replacement of the 1997 12” ductile iron watermain
on Bob Billings Parkway from Bobwhite Drive to George Williams Way, as shown on
the attached map, as the
initial project to be included in the 2014-2015 program. The existing 1997 12”
ductile iron waterline has experienced numerous failures due to the highly
corrosive soils present in this area coupled with the fact that the watermain
was installed without protective measures against corrosion.
Staff has negotiated a scope of services and fee for the design of this
project in the amount of $49,457.00. The proposed scope and fee for design
phase engineering services is commensurate and appropriate for the project. The
fee includes basic A/E design services in the amount of $42,923 as well as
non-basic A/E services related to geotechnical sub-consultant coordination,
permitting, and advertising and bidding in the amount of $6,534.
The table below reflects the proposed fee components in relation to
preliminary construction cost estimates.
Estimated Construction Cost: $541,200
Basic A/E Design Phase - % of Construction: 7.9%
Non-Basic A/E Design Phase - % of
Construction: 1.2%
Total ESA - % of Construction: 9.1%
The basic A/E design phase ESA amount as a percentage of estimated
construction cost of 7.9% is below the recommended amount of 9.1% per the design
fee guideline adopted by the City of Lawrence on January 11, 2011. Additional
non-basic A/E services itemized within the scope and fee include geotechnical
sub-consultant coordination, project permitting, and services related to
advertising and bidding.
Staff proposes to initially contract for this project with an option to
extend the contract to include additional projects, based on satisfactory
performance, with the negotiation of a supplemental agreement.
Project Funding:
The program is included in the Department of
Utilities adopted scenario 5 Capital Improvement Project and corresponding
adopted Rate Plan. The adopted Capital Improvement Project budget has $12,663,500.00
allocated for the program for the 2013-2017 period. To date a total of $2,216,707
has been expended or encumbered for design (ten projects) and construction (four
projects).
Action Request:
Authorize the City Manager to execute an
engineering services agreement with Professional Engineering Consultants for
design phase engineering services in the amount of $49,457.00 for project
UT1312DS, Bob Billings Parkway Watermain Replacement George Williams Way to
Bobwhite Drive.
