West Data Center Phase II

Papillion, NE

Overview

This project built two separate 1 MW Tier 4 modular data centers in phases roughly 14 months apart, with the first phase staying fully operational during the second's construction. Each facility includes raised-floor white space, redundant cooling and power systems (UPS, batteries, generators), strong security and fire protection, and a wind-rated hardened shell. Modular construction cut the build schedule by four months, with Phase II reaching dry-in in 15 days and full commissioning within about 19 weeks. The site can scale up to 9 MW total.

Project Details

  • (2) Tier 4 Modular Data Centers, (1) MW each, Built Separately.

  • 4,000 Sq. Ft. raised floor (1500 kW). 4,000 Sq. Ft. non-raised floor white space (500 kW).

  • Three stories – Electrical on 1st floor, white space on 2nd and mechanical on the roof.

  • Phase I was live (14) months before Phase II began installation.

  • Each phase was separated by thermally rated wall to maintain full operation of Phase I during Phase II installation, start-up, testing and commissioning.

  • (16) CRAC units per phase. Each CRAC unit is supported by a condensing unit located on the roof including pumped refrigerant economizers on custom skids, providing 592 tons of cooling. Installed with no roof penetrations. All penetrations for refrigeration lines were made in the side of the wall.

  • Two separate electrical rooms (A and B) per phase, each with (4) 550 kVA UPS’. In total (4) IT UPS’ and (4) Mechanical UPS’ per electrical room, per phase.

  • (3) battery cabinets for each IT UPS and (2) battery cabinets for each Mechanical UPS. Each cabinet holds (30)
    batteries for a total of (600) batteries per phase. Each provides battery backup, IT run time 17 minutes, Mechanical run time 15 minutes, avoiding UPS downtime.

  • Two generators are located on the exterior of the building. Each generator is a (2) MW capacity with supporting gear, Tier 4 generator. (2) generators per phase.

  • BMS controls and monitoring for both Mechanical and Electrical. All scalable platorms.

  • Fully secured facility with badge access for all entrances and several cameras throughout. Phase II included full security room.

  • Fire alarm and Sprinkler - Facility is fire protected by a pre-action sprinkler system. All services were an extension
    of the Phase I build. No new services were needed for Phase II.

  • White space has clearance of 12+ feet in height and double tier cable tray

  • Hardened shell – Exterior and roof top equipment are rated for 165 MPH wind loads

  • Modular Construction reduced schedule and site time by four months. This greatly reduced site man power needed for the build.

  • Possibility to scale out to (9) MW for a site wide build.

  • Total modules Phase II – (35) modules including (5) custom mechanical skids, (10) exterior brace frames. Build time to dry in (15) Days. Ready for permanent power (10) weeks from first module set. Electrical and Mechanical Started/Tested and Level 5 Commissioned (9) weeks from Permanent Power.
