Northwest Suburbs, Illinois
OMEGA was chosen by the Illinois Tollway to perform Construction Management Services for the relocation of the existing Northwest Suburban Municipal Joint Action Water Agency (NSMJAWA) transmission main which was located on the south side of the I-90 Right of Way from Elmhurst Road to west of Route 59.

Project Scope

The NSMJAWA relocation contract began at Barrington Road and extended eastward to Elmhurst Road with work in eight major segments, costing a total of $83 million.
