LOCATION OF PROJECT

This project is located in the City of Rolling Meadows, Cook County. The project limits along Weber Drive are from Algonquin Road (IL 62) to Central Road. The project has a total gross and net length of 3,165.5 feet (0.60 miles).

PROJECT DESCRIPTION

The work consists of earth excavation, pavement removal, construction of storm sewers, aggregate subgrade improvement, HMA roadway pavement, combination concrete curb and gutter, PCC sidewalk and multi-use path, ADA ramps with detectable warnings, driveway removal and replacement, drainage and utility structure adjustments, erosion control, thermoplastic pavement markings, parkway restoration, traffic signal and APS improvements and all incidental and collateral work necessary to complete the project as shown on the plans and as described herein.

Any additional temporary work other than what is outlined in the current plan/bid documents will not be paid for separately but would be included in the cost of the item requiring the temporary work.

General Parking will not be allowed on Weber Drive during the construction of the proposed improvements. The Contractor shall erect No Parking signs along both sides of the roadway. The Contractor shall maintain access to all driveways and side roads at all times, except for periods of time as noted in these special provisions.
