Tenant Distribution Boards Each floor is provided with two tenant distribution boards. Tenant distribution boards are subdivided into four sections to allow for tenant provided sub-metering, with standby and non-standby sections provided to each sub-section.

Metering for tenancies can be done for either North or South core, for groups of floors or for multiple tenants per floor as required.

FlexibilityEmphasis in design has been placed on the need for cable management to accommodate the demands of technology in the workplace. Principal cable access paths have been included in each core, together with a system of supplementary riser locations on the large floor areas. The system has been configured to match probable tenant locations of data wiring closets and network rooms.

To aid tenant convenience, all wiring access is within a given tenant’s floor, with access points strategically located on ducting on the building perimeter and on internal columns.

Power can be reticulated via skirting duct installed around perimeter walls and columns.
