Case Studies/Data Center Decommissioning

Clearing 120,000 SF of old Bank One

Fenway Properties bought the old Bank One buildings in Phoenix to renovate them. Quantum decommissioned the data center and cleared the whole facility — even knocking down and rebuilding a brick wall to get four vintage generators out.

The Challenge

An old bank, bound for renovation

Fenway Properties purchased the old Bank One buildings in Phoenix, Arizona. To prepare them for renovation, Quantum Technology was brought in to decommission the data center and completely clear out the facility — a 120,000 SF building.

The scope ran from the raised floor to the generators and chillers, and it included the switchgear and a long list of hazardous and high-value equipment that all had to come out before the renovation could begin.

The Approach

Right down to the masonry

The crew brought the 25,000 SF raised-floor room back to bare walls and floor, evacuated the Freon from the CRAC units, and electrically disconnected the UPS systems, transformers and switchgear. The four 1979 Cummins generators were sold despite their age — and to get them out of the building, Quantum had to knock down the outside brick wall and then reconstruct the masonry.

Fire suppression tanks were deactivated, palletized and shipped to recycling; the wet-cell batteries were disconnected with special lifts, Arc Flash suits and insulated tools; the diesel fuel was drained and resold as Diesel #2 for construction and farm equipment; and all cabling, piping and conduit was pulled and recycled.

120,000 SFBuilding fully cleared

A 120,000 square foot facility — data center, generators, chillers and all — cleared and readied for renovation, with the masonry put back where a wall had to come down.

What We Handled

The full facility, start to finish

Data center, power plant, hazards and structure.

✓25,000 SF raised floor to bare walls & floor
✓CRAC units with Freon evacuated
✓UPS systems, transformers & switchgear
✓4 Cummins (1979) generators — sold & wall rebuilt
✓Fire suppression tanks & wet-cell batteries (Arc Flash)
✓Diesel drained & resold; cabling & conduit recycled

The Outcome

Emptied, recovered, renovation-ready

The whole building came back clear — with nearly everything inside finding a new buyer or a recycler.

Cleared for renovation

The 120,000 SF facility was fully cleared to bare walls and floor and handed back ready for its renovation.

The tough extraction

Four 1979 generators came out through a wall that was taken down and rebuilt — and sold despite their age.

Recovered, not wasted

Diesel was resold as #2 fuel, compressors went to local businesses, and tanks, batteries and conduit were recycled.

Prepping a building for renovation?

We decommission the data center and clear the whole facility — generators, hazards and all — and when equipment has to come through a wall, we put the wall back.
