City Council Memorandum
To: Mayor Fasbender & City Councilmembers
From: Chris Jenkins, Parks & Recreation Director
Date: October 21, 2024
Item: Approve Change Order
Council Action Requested:
Approve Change Order for Three Rivers Trail Reconstruction Project
Background Information:
The Three Rivers Trail segment connecting the Tuttle neighborhood to East
31st Street was recently awarded. During the design and engineering phase,
staff removed a few elements to ensure the projected project costs remained
within the budget allocation. After bids were received, and a pre-construction
walk of the project, staff propose to return 2 elements to the project, and to
provide funding for an unexpected and unknown element of the project.
• Flint Hills Resources Pipeline Crossing: although it was known that
this trail would cross FHR pipelines, it was not known until the project
pre-con meeting that a high-pressure propane line was very shallow
within the trail corridor. The pipeline is 2ft deep and at that shallow
depth requires extra precautions for equipment and trucks to cross.
• Spur Trail: a spur trail that connects this trail segment to the Three
Rivers Neighborhood was removed from the bid package, it is now
apparent that it should be returned to the project, and funding is
available. This is a major connection between the neighborhood and
the main trail.
• ADA Pedestrian Ramp: the current project includes replacement of
one ADA Ped Ramp on the west side of the intersection of East 31st
Street and Amelia Avenue. It is apparent the eastern ADA Ped Ramp
should also be replaced with this project, and the cost will remain
within budget.
Our contractor has provided a cost estimate of $37,448.25 to complete this
extra work.
