Approval of Change Order for Roadway Repairs and Improvements Contract

Background

Over the past year, the Engineering Department has prepared an Americans with Disabilities Act (ADA) Transition Plan that will guide the City's Public Works Department in performing modifications to existing ADA curb ramps and sidewalks through our Annual Roadway Repairs and Improvements contract. These improvements are required by the ADA to help provide safe and efficient pedestrian access to all.

Within the past several weeks, the Public Works Department has identified 82 ADA ramp retrofits that are timely coordinated with the upcoming FY 2020 repaving work along Granny White Pike, a portion of Virginia Way, Powell Place, and Winners Circle in the Maryland Farms area. This area of town is popular for school and pedestrian traffic and made for an ideal location to begin our multi-year project to retrofit ADA ramps throughout the City. The annual Roadway Repairs and Improvements contract includes a broad range of line items, including one to cover the removal and replacement of ADA ramps. However, it has become evident that a minor contract specification modification is necessary for our ability to construct a functional and lasting product while maintaining aesthetics of the surrounding area and limiting the impacts on existing private landscape features due to ground slope and other factors.

Staff has worked with the City's contractor to identify appropriate solutions to continue to move forward, while installing a durable ADA ramp and limiting the overall impacts on the right of way and private property that immediately surrounds the installation sites.

Staff is recommending the approval of a Change Order (copy attached) to the Annual Roadway Repairs & Improvements contract, to include two additional line items. Item 604-07.30 will cover the installation of a concrete retaining wall or knee wall to be used on a case-specific basis to protect surrounding landscape from unnecessary impacts related to the ADA retrofit. Item 702-01.02 allows for the installation of a 12" deep reinforced concrete curb to be installed at these radius returns preventing buckling, crumbling, and shifting of the ramps due to the weight of vehicular traffic. Please see attached examples of these installations.

Staff believes that the contractor has offered the City a fair price for these two additional options at $22 and $25 per linear foot respectively. The use of these two line items will not affect the overall contract value or budget, rather it allows us to utilize these two additional methods to improve the overall craftsmanship of the installations already contemplated.

Please refer any questions to the Public Works Director
