The top soil on site is stripped to remove any unsuitable native material. Imported fill is then brought in and placed to build up the substation pad. This is completed with heavy equipment.

Structural steel will come in two styles: H-beam, which is large, made of fewer pieces and easier to install; and tubular, which is very similar to h-beam but tubular in form. The steel is then secured to the foundations.
