Detailed design and FEED

Civil and architectural engineering

Tetra Tech Proteus has been providing civil and architectural design services to the resources and energy sectors in Australia and Asia for many years. Our team is experienced in working with greenfield and brownfield sites, delivering the best solutions for our client’s requirements.

Civil design

Tetra Tech Proteus engineers and designers utilise various civil design software packages and systems to optimise earthworks, roadworks and drainage. Our 3D designs integrate with the 3D outputs from other Tetra Tech Proteus disciplines, ensuring a cohesive overall design. We also have the ability to develop site flood modelling for any storm event.

Our civil services include:

• Earthwork design including plant pads, storage ponds, turkey nests, fuel farms, explosives magazines, and in-pit facilities
• Roadworks
• Drainage, surface and below ground
• Culvert design
• Flood and surface water modelling
• Road and infrastructure assessments
• Creek diversions and catchment management
• Civil scopes of work and specifications
• As built drawings

Architectural design

Our architectural team is experienced in producing designs for a wide range of non-process infrastructure for the mining and resources sector, including:

• Greenfield camp layouts
• Camp extensions
• Camp remediation and refurbishment
• Building layouts such as wet and dry messes, site offices, warehouses and airport terminals
• Building assessments
• Architectural scopes of work and specifications

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.

• Safety in design
• Hazard identification (HAZID).

Mechanical and piping design

Tetra Tech Proteus has a strong track record in mechanical and piping design in both greenfield and brownfields projects. We specialise in the resources, energy and infrastructure sectors of Australia, Asia and Africa, covering all phases of a project’s life cycle from identification to operations.

We utilise a range of specialised software packages and systems to provide optimum mechanical and piping engineering designs.

We are leaders in applying Bentley’s Open Plant Modeler, with all projects modelled in 3D to achieve industry-acknowledged advantages, including:

• Multi-disciplinary integration of plant design
• Enhanced stakeholders review
• Assistance to safety, risk and constructability reviews
• Development of accurate piping fabrication drawings and bills of quantity

Our mechanical and piping service delivery include:

• Process plant design and layout
• Bulk materials handling
• Pressure vessel design
• Process pumping and piping systems
