INTRODUCTION
The enclosed resolution provides for the acceptance of the public improvement
construction contract for the Northwest Arterial / Chavenelle Intersection Left Turn Lane
Improvements Project.
BACKGROUND
Based on the previous determination to not incorporate a temporary traffic signal at the
US20 - Seippel intersection as part of the Southwest Arterial - Menards Frontage Road
project and the Southwest Arterial - US20 Interchange Grading project, the selection of
an alternate detour route was required.
In order to facilitate both the Menards Frontage Road and the US20 Interchange
Grading construction projects, both Iowa DOT and City staff evaluated detour route
options, and it was collectively determined that a local road detour using the Seippel
Road to Chavenelle to the NW Arterial route was the preferred alternative.
PRE-CONSTRUCTION CONDITIONS
After further evaluating the proposed detour route, operational issues were raised at the
existing Chavenelle - NW Arterial intersection. The original northbound NW Arterial
dedicated left turn lane onto Chavenelle was approximately 120' in length and was
under capacity with left turn traffic movements regularly backing up into the inside
northbound thru-lane. Based on original conditions, the left turn lane onto Chavenelle
did not have adequate que storage length to support the additional traffic volumes
generated from the proposed detour.
The City also reviewed and identified capacity issues with the original Chavenelle
shared right turn lane onto the NW Arterial. With the outside eastbound lane on
Chavenelle at NW Arterial originally being a shared thru and right turn lane, when
vehicles would stop and occupy the straight thru lane, vehicles were unable to make the
free right turn movement. With the right turn being a heavy traffic movement with the
proposed detour, the shared thru and right turn lane would experience backup and
congestion issues.
PROPOSED TURN LANE IMPROVEMENTS
Based on the original operational and capacity challenges the City was experiencing at
the Chavenelle and NW Arterial intersection, the completed left turn lane improvements
provided for extending the northbound NW Arterial left turn lane onto Chavenelle to an
approximate 400' storage length, while also constructing a new Chavenelle left turn lane
onto the NW Arterial, providing an approximate 210' storage length. The completed left
turn lane now allows for a dedicated straight thru lane as well as a dedicated right turn
lane which allow right turn overlap phasing which significantly improved the efficiency of
the intersection operations and the future detour route.
DISCUSSION
The Northwest Arterial / Chavenelle Intersection Left Turn Lane Improvements Project
was completed by Eastern Iowa Excavating & Concrete, LLC, of Cascade, Iowa, in the
final contract amount of $172,954.82 which is a 2.3 % increase from the original
contract amount of $169,053.83.
RECOMMENDATION
I recommend that the City Council accept the public improvements and authorize the
payment of the contract amount of $172,954.82 to Eastern Iowa Excavating & Concrete,
LLC, for the Northwest Arterial / Chavenelle Intersection Left Turn Lane Improvements
Project.
BUDGET IMPACT
The City was awarded a U-STEP grant to cover a portion of the costs for the left turn
lane improvements. Based on the approved U-STEP funding, the Iowa DOT will cover
55% of eligible construction costs, up to a maximum of $200,000. The City will be
responsible for 45% as local match. The City will also be responsible for the engineering
design and construction administration related costs.
The summary of project costs for the Northwest Arterial / Chavenelle Intersection Left
Turn Lane Improvements Project, is as follows:
Description Cost Bid Award Final Cost
Estimate
Construction $ 212,263 $ 169,053.83 $ 172,954.82
Contingency 21,226 21,226.30
Engineering Design &Administration 35,023 35,023.40 25,943.22
Total Construction Cost Estimate $ 268,513 $ 225,303.53 $ 198,898.04
The funding for the Northwest Arterial / Chavenelle Intersection Left Turn Lane
Improvements Project will be as follows:
CIP No. Fund Description Cost Bid Award Final Cost
Estimate
3002695 U-STEP Funds $ 128,419 $ 104,654.07 $ 92,388.14
3002695 NW Arterial Left Turn Lane 140,094 120,649.45 106,509.90
Total Project Funding $ 268,513 $ 225,303.53 $ 198 898.04
The NW Arterial Left Turn Lane (CIP 3002695) funding is a reallocation of funds from
the Heeb Street - street construction project (CIP 3002612). The section of Heeb Street
(near Kaufman Ave.) was budgeted and scheduled to be reconstructed in conjunction
with planned underground water and sanitary sewer projects. However, funding for the
respective street, water and sanitary sewer projects have been delayed while staff
evaluates SRF or HUD funding alternatives.
ACTION TO BE TAKEN
The City Council is requested to adopt the attached resolution to accept the public
improvements and to authorize the final payment of the contract amount of $172,954.82
to Eastern Iowa Excavating & Concrete, LLC, for the Northwest Arterial / Chavenelle
Intersection Left Turn Lane Improvements.
