  • Concrete foundations and slab on ground to support Capability Contractor’s Satellite Tower, Data Cell, including all ancillary elements.

In addition to the infrastructure works being carried out at each Satellite Ground Site, the St Hillier EST1442-6 Project will also undertake associated upgrade works within the Defence Network Operations Centre (DNOC) at HMAS Harman, and the Defence Communications Building at HMAS Stirling (DEFCOMSTA-Perth). Both these buildings located at each respective interstate bases are highly secure and secretive buildings, forming the hub from which all telecommunications are dispersed and received from naval platforms (ships). Within these communications buildings, there are multiple Sensitive Compartmented Information Facilities which act as compartments with full Dw50 acoustic and 4hour fire rated construction. Access to SCIFs is strictly limited to those individuals with appropriate security clearances, meaning Non-cleared personnel in SCIFs must be under the constant oversight of cleared personnel and all classified information and material removed from view in order to prevent unauthorized access. As part of this process, all personnel entering a SCIF are required to surrender all recording, photographic and other electronic media devices (ie smart watch, phones, cameras, fitbits, GPS etc) as all of the activity and conversation inside is restricted from public disclosure. St Hilliers scope within these SCIF compartments at each communications building include the following;

  • Demolition of existing walls
  • Build new Dw50 acoustic rated walls slab to slab (approx. 4metres high).
  • Install new ceiling lighting.
  • Install new electrical (power & communications).
  • Build an air-lock
  • Install new doors & frames.
  • Install x14 new workstations.
  • Install new FF&E throughout.
  • Install new floor coverings.
