LOCATION OF PROJECT

This improvement is located along FAU 2843 (Dixie Highway) over Thron Creek Tributary (0.4 miles North of IL 1) in the City of Chicago Heights, Cook County, IL.

DESCRIPTION OF PROJECT

The scope of work for this improvement includes replacement of the existing concrete box culvert (SN 016-0926) with a proposed triple cell concrete box culvert (SN 016-8321) comprised of a 12' W x 7 'H main cell and 2 - 8' W x 7' H flanking cells, with all cells embedded 1' in the ground, and the two flanking cells will include a weir wall at the upstream face. The sidewalk foot bridge east of the culvert will be removed, and a new sidewalk will be located over the proposed culvert and extend to 10th Street on the west side of the school and the west ditch north Hawthorne Lane will be regraded. The sidewalk on the west side over the proposed culvert will be widened to 10’ for future bicycle accommodations.

Section FAU 2843 22 CR

The above represents the best information available to the Department and is included for the convenience of the bidder. The days required for conflict resolution should be considered in the bid as this information has also been factored into the timeline identified for the project when setting the completion date. The applicable portions of the Standard Specifications for Road and Bridge Construction shall apply.

Estimated duration of time provided above for the first conflicts identified will begin on the date of the executed contract regardless of the status of the utility relocations. The responsible agencies will be working toward resolving subsequent conflicts in conjunction with contractor activities in the number of days noted.

Section FAU 2843 22 CR

The estimated relocation duration must be part of the progress schedule submitted by the contractor. A utility kickoff meeting will be scheduled between the Department, the Department’s contractor, and the utility companies when necessary.

The contractor is responsible for contacting JULIE (or DIGGER within the City of Chicago) prior to any excavation work. Please note that IDOT electrical facilities are not part of the one-call locating services, such as JULIE or DIGGER.

If the contract requires the services of an electrical contractor, it is the contractor’s responsibility, at their own expense, to locate existing IDOT electrical facilities before commencing work. For contracts that do not require an electrical contractor, the contractor may request one free locate of IDOT electrical facilities by contacting the Department’s Electrical Maintenance Contractor.

Additional locate requests will be at the contractor’s expense.

The Department’s Electrical Maintenance Contractor must be notified at least 72 hours in advance of the work by calling 773-287-7600 or emailing dispatch@meade100.com to arrange for the locating of underground electrical facilities.

Please note, the marking of underground facilities does not absolve the contractor of their responsibility to repair or replace any facilities damaged during construction at their expense.
