Data Center Hardening and Expansion

Client: The Hartford Insurance Company

One of the largest international investment and insurance companies based in the United States contacted SIGMA7 design group to assist them with the consolidation of their enterprise data centers as well as the hardening, expansion and upgrade of their existing enterprise data center.

After studying the existing physical infrastructure and analysis of their ongoing growth and expansion, the scope of the project was finalized based upon an upgrade and expansion of their existing Tier I facility to a Tier III facility. The online upgrade to the enterprise level data center facility includes phased renovation of the entire two floor 60,000 SF data center, the installation of a redundant heat rejection system and increasing the incoming electrical utility service capacity 15MVA with 2N redundant service. A new 7,500 SF consolidated tape vault, library and operations facility was also implemented.

Upgraded electrical and mechanical infrastructure is housed in a new 35,000 SF multi-story building addition, which includes 2N Critical power. The mechanical infrastructure, also based on N+2 redundancy is designed utilizing a new air cooled chiller plant to complement the existing water based heat rejection system. The waterless heat rejection plant maximizes the efficiency of annual cooling costs and eliminates reliance on water.

Site design includes the relocation of on-site surface parking to accommodate the building expansion as well as the development of reinforced security rings to protect this critical asset.

This project was implemented on a live data center operation over a 5 year period without any shutdowns to critical processing. This project included on-site coordination and full commissioning and integrated testing.
