Design + engineering


In the context of utilities and infrastructure, achieving great results depends on great people who excel in conceiving and implementing good practical, safe solutions, based on a sound understanding of asset, life cycle and performance solutions.

Our design and engineering solutions include overhead lines, underground cables, substations, protection and control systems, telecommunications, subdivisions, lighting, and CAD Services.

Our clients engage with us in a number of ways – Design Build, Design Tender, or on a Project Management basis.

Clients who wish to separately tender their construction work still have the flexibility to utilise Connetics’ Design or Project Management services independent of our operational services business. This service includes obtaining Network Operator approvals, evaluation, and providing recommendations on the tender process for construction.

Our extensive project management experience enables Connetics to take a project from concept to completion on time and to budget.

Connetics also offers an independent engineering evaluation of utility electrical distribution equipment and designs.
