RE:

Burroughs Creek Rail Trail – Change Orders

Project PW0829

 

Please include the following item on the City Commission consent agenda for consideration at the November 16, 2010 meeting:

Approval of Change Orders for Burroughs Creek Rail Trail Project

 

Project Details:  The project consisted of a 10 ft wide concrete trail for pedestrian and bicyclists extending from 23rd Street to 11th Street along the abandoned BNSF railroad corridor located just west of Haskell Avenue. Total length of trail is approximately 8,900 linear feet. 

Project Additions:  The low bid was significantly lower than the anticipated project cost.  To utilize more of the grant money, City Staff worked with the neighborhood and KDOT to add two improved connections to the main trail. 

 

The two additions connections were:

·       Removing and replacing the concrete sidewalk that intersects the trail between 12th & Oregon and Haskell Avenue with a 10’ wide path

·       Removing and replacing the concrete sidewalk along 11th Street to connect the north end of the trail to Hobbs Park with a 10’ wide path

 

Other change orders included the addition of several drainage structures underneath the trail from 19th to 23rd St to facilitate drainage, additional riprap to prevent erosion, a retaining wall adjacent to the south trail wheel at the 15th Street crossing, and railroad tie removal.

 

Project Funding:

This project is part of the 2009 KDOT Transportation Enhancement Program.  The funding is 60%/40% (KDOT/City) split with a KDOT maximum participation of $500,000.  The city would be responsible for 100% of the costs exceeding a total project cost of $833,333.33.

 

Final Construction Costs

 

Original Contract

$591,632.97

Change Orders

$74,949.67

TOTAL PROJECT COST

$666,582.64

 

The final project cost of $666,582.64 will be split $399,949.58 (KDOT) and $266,633.06 (City).  The city’s cost share is being paid from the $350,000 allocated to the project from the approved 2008 sales tax proposal for streets and infrastructure.

 

Action Request.  Public Works staff requests approval of Change Orders in the amount of $74,949.67.

 

Respectfully Submitted,
