ORT Design for Plazas 1, 5 & 7

SINGH provided Mechanical, Electrical and Plumbing Engineering services to the Tollway Authority as a subconsultant to HDR Engineering Inc. This project includes the construction of three toll plazas in Winnebago, Boone and McHenry Counties, respectively. Plazas 1 (Beloit), 5 (Belvidere) and 7 (Marengo) are being converted to Open Road Tolling facilities. Completely new administrative building is constructed for plaza 1 while the buildings for plaza 5 and 7 are expanded and renovated. These plazas will have three express lanes (two proposed and one future) with full shoulders in each direction. The conversion will require reconstruction or rehabilitation of existing toll collection facilities and design tasks to upgrade existing toll plazas, and new designs for the proposed ORT lanes. Also included in the project are antenna tower relocation; electric utility relocation and new service coordination;        site utility and electronic equipment survey and record drawings; temporary dynamic message sign; emergency generator for critical and non-critical loads and several other tasks.

90/94 Dan Ryan Expressway, Electrical Engineering & Roadway Lighting
Chicago, IL

SINGH is currently providing professional engineering services for the preparation of Contract Plans and Specifications for a new lighting system for the Dan Ryan Expressway from 95th Street to 69th Street. The entire project consists of the reconstruction and widening of this major expressway from 4 to 5 lanes, improvement to existing retaining walls, traffic signals, auxiliary lanes and a new highway lighting system.

The project requires high mast and conventional lighting. The roadway also contains a wide median occupied by a multi-track commuter rail line. The proposed design will overlap plans for removal of existing luminaires, temporary lighting, power fields and installation of over 100 high mast lighting units. SINGH’s design will accommodate the removal of temporary lighting and the installation of permanent lighting over several years without any lane closures on the expressway. The expressway has high traffic volumes of more than 300,000 vehicles per day. SINGH’s team is coordinating with other consultants to insure that a uniform bid package is provided.

SINGH’s design will be completed using a state of the art lighting design program. The engineering team will confirm Illinois Department of Transportation photometric performance requirements. A major component in the successful completion of this project includes maintaining strong communication links with IDOT, lead consultant and section consultant during design and plan preparations. This project requires the team to gather engineering resources to provide rapid updates to contract plans as the design direction is confirmed with IDOT and engineering decisions are implemented. The total construction cost for this project is $430M.
