JTM Construction Group Inc. upgrades Miami MI1 data center to global gateway

Power and cooling capacity with redundancy a priority, along with customer colocation facilities, at this key network exchange.

Miami MI1 was an existing 750,000 sq. ft. data center built in 2001 that was purchased by JTM Construction Group Inc.’s client and designated for upgrades to facilities, MEPS, technical systems, security, landscaping and more. The six-story building in downtown Miami required extensive logistical and mechanical expertise to meet the expansion and upgrade challenges.

Now MI1 is the country’s largest communications gateway to Central and South America, and uses sub-sea cables for capacity and speed. Formerly known as Network Access Point (NAP) of the Americas, MI1 is a critical link in the data traffic pathway to 148 countries worldwide. It hosts 6,500 colocation cabinets and a dedicated floor for secure federal government operations.

Project elements

JTM Construction Group Inc. completely renovated the first floor, including the front façade, entrance and lobby with customer security area. They enclosed the existing exterior arcade to create a new interior walkway, remodeled five corporate suites, created a new corporate lounge and added a conference center.

Work on the second floor included a new customer area with amenities, an additional 1,300 colocation cabinets and operations offices. The fifth floor buildout featured colocation cabinets, and mechanical equipment and controls. The sidewalk and landscaping renovation matched the neighborhood’s design as designated in the community master plan.

Equipment installation

The team installed a massive amount of MEPS equipment with full backup/redundancy and complete commissioning. The highlight of this complex effort was the installation of three 3MW power blocks for electrical distribution, and 14 new high-efficiency rooftop chillers. They also installed a MV switchgear lineup to accept new redundant 13.2kV public utility service feeders. They replaced some existing fuel oil piping, infrastructure equipment and controls.

JTM Construction Group Inc. upgraded all security, Building Management Systems and Electrical Power Management Systems, including a new controls platform, all without interruption to facility operations or colocation customers.
