Northwestern Memorial Hospital – Chicago, IL

Provided complete systems design for $300 million (GC) hospital, telecommunications portion was $15 million. Telecommunications systems design including voice/data/wireless infrastructure, nurse call, overhead paging/intercom, CCTV/security/access control, PBX, EMS Radio, and LAN/WAN hardware.

 

Level 3 Communications – St. Louis

Upgrade, including new STS/PDUs, 500 KVA UPS addition, and 8000 SF Raised Floor Addition for existing Co-location Facility. Provided coordination study.

 

Hammond Developmental Center - Hammond, LA

2000 KW, 13.8 KV Standby Generator with 10,000 and 4000 gallon fuel tanks and modification to the existing 13.2 KV switchgear and controls and breaker for a second (future) 2000 KW unit.

Children’s Hospital – New Orleans, LA

Designed modifications to the existing hospital essential system generators which consisted of 2-750 KW generators paralleled at 480V and a second system consisting of 3-750 KW generators paralleled at 480V. The paralleling systems were combined to provide for the parallel operation of 5-750 KW generators on a common split bus. The system effectively provided sufficient capacity for the operation a an additional 900-ton centrifugal chiller on the essential system. This additional capacity and redundancy was made available without the addition of a single KW of generator capacity and saved the hospital over a million dollars.
