Tenant Build-Out Project Spotlight

Tenant Build-Out Project Highlight

When a large law firm needed to expand and modernize its offices, they called on Gibson Electric for a complete package of electrical contracting services.

During the project, we installed a complete structured-cable system, the highlight of which was a data center build-out and riser providing high-speed interconnectivity to the rest of the office suites.

The facility’s two floors worth of data center space features:

  • Separate and dedicated electrical service and distribution systems
  • Emergency generator
  • Uninterrupted power supply (UPS)
  • N+1 power support

Throughout the entirety of the project, Gibson Electric maintained our client’s strict move-in schedule. The remaining 25-floor build-out included:

  • Two complete high-end conference centers
  • State-of-the-art conferencing ambiance controls
  • Comprehensive electrical installation
    • Voice/data structured systems
    • Life safety systems
    • Lighting fixtures
    • Electrical receptacles
