Careers

It’s time to shine the spotlight on our Putaruru-Arapuni 110kV Ducting Project.

This project was to construct a new 110kV transmission line from Arapuni Power Station to Putaruru Zone Substation.

The line route is from the Transpower owned Arapuni Substation to the Powerco owned Putaruru Sub Station and is a combination of road berm, with sections of the line across private property (farmland with 4WD access).

Trench consists of;
3 x 160mm PE ducts jointed via electrofusion couplers.
2 x 32mm PE ducts
1 x 63mm duct.

Total meterage of combined trench installed = 3400m

Of this total meterage, there was 2 drill shots (1 at 40m and 1 at 120m) and 2 bridge crossings in specialist steel ducts (both at 30m each)

The scope of work for this Contract includes the supply of all management, administration, Engineering, labour, plant, materials (other than those supplied by Powerco), equipment, tools, etc., required to complete the Works

The works involve:

Services location and relocation
10,200m of DN 160 PE 100 pipes by open cut and 2 No. directionally drilled sections
Passage through roading reserves, private landowners with permanent and temporary easements for placement and construction of pressure pipes
5 joint bays which consist of 14m long, 2.5m wide and 1.2m high reinforced concrete boxes
