Installation of Switchrooms

Facility Description

The Main DBS Switchroom and 2 supporting Switchrooms are an essential component of the Tanami Expansion 2 (TE2) project, located at Dead Bullock Soak (DBS) within the Newmont Tanami Operations in the Northern Territory of Australia. This facility is designed to support the enhanced electrical infrastructure required for the expanded mining operations. The switchroom installation involves significant structural steelwork, platform construction, and modular building placement, ensuring the provision of reliable electrical distribution to the site.
