Complete Project Lifecycle Engineering Services.

ACRE provides comprehensive engineering services throughout the project lifecycle, from initial concept development to commissioning. Our methodical approach ensures that project viability is thoroughly assessed before significant capital expenditure.

Feasibility Studies

We conduct rigorous pre-feasibility and feasibility studies that:

  • Evaluate project viability and alignment with strategic objectives
  • Explore and compare alternative approaches
  • Establish realistic project parameters and expectations
  • Identify potential risks and develop mitigation strategies
  • Assess business case fundamentals and return on investment
  • Provide detailed implementation roadmaps

Our feasibility assessments involve collaborative workshops with clients to test assumptions and evaluate alternatives through weighted selection processes, ensuring rational, well-informed decision-making.

Railway and Infrastructure Design

ACRE specialises in railway and related infrastructure design, incorporating structural engineering for bridges, culverts, and associated structures. Our design services include:

  • Rail and Route Alignment: Utilising advanced digital terrain modelling and engineering analysis to optimise alignment based on CAPEX, OPEX, and constructability constraints
  • Earthworks Specification: Developing bulk and specialised layerworks designs with optimised mass haul, based on material availability and axle loading requirements
  • Permanent Way Materials: Specifying appropriate materials based on axle loading design and operational parameters
  • Structural Engineering: Designing railway bridges, culverts (pipe and box), and related structures
  • Drainage Systems: Engineering comprehensive drainage solutions to ensure infrastructure longevity
  • Specialised Facilities: Designing marshalling yards, loading/load-out facilities, and associated infrastructure
  • Multi-disciplinary Integration: Coordinating interfaces with locomotive maintenance workshops, electrical reticulation, overhead traction equipment, signalling systems, yard lighting, and other related disciplines

Our design approach balances technical requirements, cost considerations, and long-term operational needs to deliver optimal railway infrastructure solutions.
