Principal: Alinta Energy

Client: UGL Engineering

Duration: 2014-2015

Location: 70km South of Port Headland (Roy Hill) to Newman

Project Description:

  • 120km of 220kV single circuit transmission line between the Newman Power Station and RHIO Mine
  • a 66/220kV substation and associated 66kV connecting works at Newman
  • a 220/33kV substation at RHIO Mine
  • a 6MW reciprocating diesel engine Power Station at RHIO Mine
  • a 33kV electrical distribution system at RHIO Mine

Survey Scope:

ST Spatial had two fulltime survey crews on site covering the entire site from Newman to Roy Hill.  We were responsible for the co-ordination and calculation of the staking table report, and setout of all structures including towers, legs and ground anchors, line deviation angles, ahead spans, leg extensions, site benching, guy anchors, and orientation pegs.

We completed as-con surveys and setouts in both Newman and Roy Hill substations and were responsible for the full as-built model for the entire project spanning 120km.
