RE: |
Iowa Street (US-59 Highway, Yale Road to Bob Billings Parkway Street Reconstruction and Geometric Improvements – PW1012 Engineering Services Agreement for Surveying August 18, 2010 City Commission Agenda |
Background: Iowa Street was constructed in 1951 – almost 60 years ago. On April 27, 2010 the City Commission received a report from staff on the condition of Iowa Street from Yale Road to Bob Billings Parkway, noting this area had the most significant failures (4/27/10 memo). The direction from the City Commission was to proceed with design for reconstruction of this section of Iowa. Staff recommended the engineering firm of Bartlett & West to complete the design of this project and the City Commission approved this recommendation on July 13, 2010.
Status: The City milled and overlaid Iowa from Irving Hill Overpass to Yale Road earlier this spring as a result of significant deterioration due to the severe winter and failing base. Significant rutting is now occurring on the northbound and southbound lanes south of Bob Billings Parkway. Attached are pictures of core samples which show the base failure.
Because this is a State Highway, staff and Bartlett & West met with KDOT to discuss the scope of the project. Traffic modeling, utility issues and KDOT expectations were discussed as well as design issues for lane widths, intersection improvements, pavement section and materials.
Details: To get the project moving, staff is requesting City Commission consideration of a contract with Bartlett & West to begin surveying Iowa from Harvard Road to Bob Billings Parkway. KDOT plan development/review is a 27 month schedule and the City would like to bid this project at the end of 2011/beginning of 2012 (18 months).
In order to provide the consultant with a well defined scope of service and receive the most cost effective project, several issues need further investigation, discussion, and clarification to direct what improvements should be included within the project.
Issues Needing Further Review:
|
· Project Limits – Will the project extend south of Bob Billings Parkway? This would include both engineering and construction costs. · Sidewalks - The sidewalk on the west side is continuous. The east side has a new sidewalk that ends at University Drive. Do we want to continue the sidewalk on the east side to Bob Billings Parkway? There is a significant drainage channel to cross and a hill at the intersection. Staff has also been asked to evaluate if a multiuse path could be included in the project. Issues of right-of-way, cost, and design need to be reviewed further for the sidewalk/multiuse path needs.
· Intersection - If the project extends south of Bob Billings Parkway should the intersection be included? Should the intersection be reconstructed with the same configuration or look at future traffic needs (right-turn lanes, dual left turn lanes)? · The westbound lane of Bob Billings Parkway has a substantial grade difference. If the intersection is rebuilt should the grade of the westbound leg on Bob Billings Parkway be improved? |
Staff would like to provide the Commission with additional information on these items and receive direction before an engineering contract is completed. This will ensure that we do not over/under design the project and are able to deliver the most efficient design.
Action requested: Authorize City Manager to enter into an Engineering Services Agreement with Bartlett & West for surveying services in an amount of $33,575.00.
