Project Description

The patch and microsurfacing portion of the project includes a number of City residential and collector streets generally bordered by W. 6th Street to KU and Iowa Street to Illinois Street.  The arterial N. Iowa Street from Peterson Drive to Lakeview Road is also included for microsurfacing.  Streets to receive microsurfacing are determined to be in generally good condition.  Streets deteriorated beyond the recommended condition for microsurfacing and included with this project are shown as milling and overlay (see location map).

 

Project History

The City’s annual pavement maintenance program was reviewed and approved by the City Commission on February 24, 2015.  Other contracted maintenance program projects such as the 2015 Crack Seal Program (to be performed by City internal crews), the 2015 Overlay and Concrete Rehabilitation Program, and the KLINK Milling and Overlay project are also planned for this construction season as presented at the February 24, 2015 City Commission Meeting.

 

Project Details

The project includes various surface and full depth patching of deteriorated areas on City streets followed by the microsurfacing of the entire pavement surface OR milling, patching, and overlay as designated.  All existing pavement markings will be reestablished.  Additional bicycle pavement markings (sharrows and bike lanes) will be included on several streets within the project work areas as coordinated by the Public Works Department based on recommendations from Bicycle Advisory Committee.

 

Based on the low bid unit pricing, there is approximately $28,000 in pavement markings that are part of the planned improvements for new bicycle facilities (sharrows and bike lanes).

 

Project Funding

The pavement maintenance program is typically funded from several sources.  Funding for the program was approved in August, 2014 and adopted in the 2015 City Budget.  This project was included in the 2015 Pavement Maintenance Program for microsurfacing and overlay to be paid from the general fund and sales tax.

 

The low bid exceeds the engineer’s estimate by $32,824.60.  There has been an increase in overall construction costs/unit pricing of some major items of work and have seen higher overall project costs with the inclusion of added facility improvements outside of street maintenance activities.

 

Other projects to be bid in the coming months such as the 2015 Overlay and Concrete Rehabilitation Program will need to be reviewed for scope of work with possible street maintenance reductions or deferred maintenance to a future program year.  Staff has been reviewing construction cost impacts and plans to provide recommended adjustments to the overall street maintenance program fund dispersion in a separate report / memorandum for a future agenda review.
