H.I. Fraser’s Environmental Solutions Department helped Sydney’s Latest 6 Star Office Building, 1 Bligh Street set new standards in green technology.

Project Summary

H.I.Fraser Group were awarded the task to supply the EVAC Vacuum Collection System for this iconic building with the system primarily being utilised to collect trade waste discharge from mid and high level base building services.

In addition, the EVAC Vacuum Collection System allows the building owner to offer 100% Net Leasable Space (NLS) on sub tenancy fit-outs by providing vacuum access points on each level to collect from any installed hydraulic service.

This has provided tenants with full flexibility on placement of services with no requirement to penetrate the slab during ongoing refits after the building has been completed.

Tenants have the option to install Toilets, Showers, Basins or Kitchenettes almost anywhere on the floor plate.
