title
Professional Services Agreement for the I-80 and Center Street Interchange Interceptor Rehabilitation Design, to RJN Group Inc. in the amount of $141,700.00
end
BACKGROUND:
The Illinois Department of Transportation (IDOT) is currently in detailed design to reconstruct I-80 from Chicago Street to west of Center Street, including replacement of the I-80 bridge over the Des Plaines River. IDOT's project creates many utility conflicts with the City's water, sanitary sewer, and storm sewer systems.
The City retained V3 Companies to complete preliminary IDOT I-80 reconstruction coordination and a Joliet Water and Sewer Relocation Feasibility Study. V3 Companies has reviewed the I-80 reconstruction plans and determined that the reduction of soil cover on the City's 48-inch interceptor that services the west side of the river will cause structural concern for the interceptor during the construction of the I-80 project. It has been recommended that the interceptor be rehabilitated prior to mass grading for the I-80 project. This recommendation has been reviewed by IDOT, and IDOT agrees with the recommendation of rehabilitating the interceptor prior to mass grading construction.
The City prepared a request for qualifications for the sewer investigation and rehabilitation program that was advertised on December 16, 2021. Upon review of the qualifications, RJN Group Inc. was selected as the most qualified firm to manage the City's program. RJN Group Inc. has been assisting the City with the Sanitary Sewer Investigation and Rehabilitation Program since 2014 and has a local office in Joliet. Since 2014, RJN Group Inc. has become very knowledgeable of the City's collection system and is integral to the continuation of the program. Accordingly, RJN Group was requested to provide a proposal to complete the design engineering work for slip lining this sanitary sewer.
