Client Canterbury District Health Board

Completed June 2016

Location Christchurch

Scope & Scale

Construction of new 2-storey IL4 concrete and masonry substation building (380m2 floor area) including:

  • new service tunnels and electrical mains to hospital labs and boiler house
  • installation of new switch boards and electrical protection equipment.
  • staged relocation and livening of three 1000kVA transformers
  • relocation of 1000kVA generator (for hospital essential supply)

HRS also installed a new 70,000 litre underground diesel storage  tank including all associated mechanical and electrical.

Performance

HRS prepared a sound methodology incorporating safety requirements, underground services location, temporary propping, scaffolding, and sequencing of work, and electrical and mechanical commission and testing. HRS successfully managed significant services installation drawing on the resource of Electrical Subcontractor Aotea Electrical.

Timely pricing and open and upfront communication of the programme impact assisted in the management of the high volume of variations.

The project was adjacent to labs that contained sensitive equipment – the mitigation of noise and vibration was paramount and successfully managed by HRS.

The project called for a high level of communication and co-operation with other CDHB contractors and the hospital itself. HRS followed all necessary protocols and processes regarding the application for and timing of shutdowns.
