Client – Chicago Dept. of Aviation
Project – LLWAS #8 & #15 Fiber Optic
Overview – Low Level Windshear Alert Systems (LLWAS) are used to measure wind speed and direction around the Chicago O’Hare International Airport. As the O’Hare airfield expands there is a need to relocate these systems. Work included installing 30’ deep x 4’ diameter caissons for 80’ poles, underground utility duct banks, perimeter security fencing, asphalt driveways and finished gravel surfaces. All work was performed in accordance with FAA regulations.

Fiber Optic Cable From Aviation Administration Building to Aviation Security Building

The fiber optic communications cable from the aviation administration building to the aviation security building was re-routed due to the development of a cargo facility in the area of the previous duct bank. Work included trench excavation and backfill, installation of approximately 1,800 linear feet of 2 way concrete encased duct bank, installation of 48 strand fiber optic cable, placement of necessary hand-hole structures and pavement and landscape restoration. All fiber strands were terminated and tested accordingly.
