The new facility is the fastest data center construction on record (Cyrus One typically takes 34 weeks to complete construction – Goliath Data Center completed in 26 weeks) and includes:
■ Accommodate a shell of approximately 400,000 square feet
■ Provide up to 240,000 colocation square feet (CSF)
■ Offer 36,000 square feet of Class A office space
■ Deliver up to 48 megawatts of critical load
■ Low Blow Count Clay and Silt Fill in the upper 4 to 8 feet
■ Shallow Rock with variable depth to rock – 4 to 12 feet
■ Tight Settlement Criteria for the floor Slab – < 0.5 inches
■ 250 psf floor loads
■ Get it done ASAP – yesterday is too late!
With only 26 days to complete the project over the holiday season, GeoStructures utilized 24-inch Cement Treated Aggregate (CTA) Geopier® elements (15 X 20 ft spacing). A 12-inch stone layer shear break was placed on top of each CTA Geopier element to allow for shear break between the pier and the footing or slab. The CTA Geopier elements provided the quickest solution with virtually no settlement. Depths ranged from 0 ft. refusal on rock to 14.5 ft. (12 piers eliminated on rock). Despite facing a snowstorm and the holiday season, GeoStructures worked closely with HITT Contracting, Inc (general contractor) and Cardno Haynes Whaley Associates (structural engineer) to allow for a fast-track design and schedule.
