Integrated Bldrs Infrastructure Upgrades

Integrated Builders has completed electrical and mechanical upgrades for a Fortune 500 technology company in Massachusetts.

Braintree, MA – Integrated Builders has completed electrical and mechanical upgrades for a Fortune 500 technology company in Massachusetts.

The project consisted of electrical and mechanical upgrades to existing systems to accommodate the existing data center plant. 

Electrical upgrades included a new 2500 KVA Pad Mount Transformer and a Siemens 4000 AMP 480v switchboard with distribution through four Siemens 480v switchboards. 

Distribution to the data center was made through four 500 kw Eaton UPS systems and eight 300 kva  Cyberex  PDU’s. All power systems are backed up with a 2500 kw Catepillar generator.  Mechanical upgrades include three, 200-ton chillers with glycol, three primary pumps, and three secondary pumps as well as the mechanical room.

 Distribution for the new chilled water in the data center was through  22 APC In Row Coils and five 40 ton Leibert systems . Two 13,500 cfm air handlers were used to cool the electric room All DC controls were provided by JCI.  The project included some closely coordinated efforts including running all new chilled water, make up water, drains, conduits and feeders under a raised floor in the existing operating data center. The electrical feeders into the building, out to the generator, and under the electric room floor required interior excavation and the layering of the different conduits. Al of this work was done next to and under occupied work areas.

The site portion of the project included 2500lf of trench excavation for the new primary electrical feeders, a new pad area for the chillers and generator, and the relocation of the building water line to accommodate this pad. The existing 2500 kva utility transformer feeding the data center was also put on the new NGRID switch.
