Electrical and instrumentation design

Electrical and instrumentation design

Engineering design

Tetra Tech Proteus undertakes both greenfields and brownfields electrical, controls and instrumentation design work.

Our team is experienced with carrying out site investigations, recommending design outcomes that best suit the client’s requirements, providing fully checked detail designs to minimise re-work during construction, as-building existing installations prior to starting design to achieve highly efficient construction and commissioning outcomes.

The team consists of engineers and designers experienced in all electrical and controls facets.
