Background
A change order to Project 18-14, Bridge Rehabilitation Improvements will be required due to additional bridge sidewalk patching areas above contract quantities that were identified during removal work and unanticipated additional costs for IDOT traffic control, CTA flagging, and CSX permit requirements. The various changes are described below and were authorized during construction in order to reopen bridge sidewalks, properly complete the project, and be compliant with IDOT’s and the railroads’ requirements.
During sidewalk patching on the Oak Park Avenue Bridge this spring additional patching areas were required due to the deteriorated conditions of the existing concrete and steel reinforcement. These additional patching areas were not originally included for replacement and were discovered during construction and required to be replaced in order to properly repair the sidewalks and reopen the bridge. Bridge deck and sidewalk patching quantities exceeded the originally awarded contract amount by approximately $93,000.
In addition to the additional patching areas, the contractor was required to provide additional railroad flagging and traffic control beyond originally anticipated in order to complete the work and obtain permission to work within their right of ways. Additional permit requirements for work this spring by CTA required revised traffic control on I-290 and additional railroad flaggers. CSX and CTA revised insurance requirements were also required this spring as well as additional work to comply with CSX flagger’s scheduling was needed. The additional costs for railroad related permit requirements this spring amounted to approximately $38,800.
All work is complete on this project. A separate project for repairs to Home Avenue and East Avenues was awarded by the Village Board in July of 2019 and is currently under construction.
