Structural Engineering Consultants

Structural engineering deals with the design, construction, maintenance and assessment of permanent and temporary structures or structural systems.  Structures are designed to work within their environment and accommodate relevant external forces such as wind, waves, earthquakes, etc.  Structural engineers work closely with Orana Engineering’s other engineering disciplines such as mechanical and electrical to provide a complete design solution for our clients.

Orana Engineering can provide a range of structural engineering services including assessments and design of:

  • foundations;
  • access platforms;
  • services (e.g. pipework, cable ladder, etc) supporting structures;
  • monorails; and
  • structural inspections and audits.

We service coal, metalliferous, oil and gas clients as well as industrial and commercial clients. Explore the case studies below for more information on structural engineering services by Orana Engineering.
