Bridge and Culvert Engineering Services

Bridges

We bring extensive experience in the design of rail, road, and pedestrian bridges, boardwalks, and culvert structures. Our approach begins with a thorough understanding of the functional need and site-specific conditions, allowing us to tailor engineering solutions that are practical and cost-effective.

For instance, in flat terrain areas, culverts often serve as balancing structures or driveway crossings. We assist clients in not only designing the structural and civil components of the culvert but also in quantifying the required discharge handling capacity to ensure hydraulic adequacy. Our services also include providing technical justification for the necessity and configuration of the culvert, supporting both design compliance and project approvals.

Retaining Wall Engineering Services

Retaining Walls

At HNR Associates, we bring specialized expertise in the design of retaining structures, backed by technical research and industry recognition. One of our team members has authored a published technical paper on retaining wall design, demonstrating our depth of knowledge in this field.

In Australia, the most used retaining system is the bored pier post and sleeper wall. However, every site presents unique challenges, and selecting the right retaining solution often requires careful assessment beyond standard practices.

We assist clients in evaluating the most suitable solution for their project:

  • Post and Sleeper Walls
  • Cast-in-Place Concrete Walls
  • Gabion Basket Walls
  • Or other specialized retaining systems

Our approach ensures that the chosen solution is structurally sound, cost-effective, and appropriate for the specific site conditions, balancing functionality, aesthetics, and compliance.

Screw and Bored Piers Foundation Services

Screw & Bored Piers

Bored piers have long been regarded as the gold standard for heavy load-bearing foundations, known for their strength, durability, and reliability in challenging ground conditions. However, modern construction often demands faster and more cost-effective alternatives, and screw piles have become a preferred solution for contractors due to their speed of installation and minimal site disruption.

At HNR Associates, we recognize that choosing between bored piers and screw piles is not a one-size-fits-all decision. Every project is assessed carefully, considering site-specific geotechnical conditions and project requirements.

Our team's expertise includes:

  • Over five years of experience designing pile-founded elevated viaducts
  • Involvement in the design of 1,000+ deep bored piles (~30m depth) for major infrastructure projects

This depth of experience allows us to guide clients in making informed decisions on foundation systems, balancing structural requirements, cost, and construction efficiency.

Road Design Engineering Services

Road Design

At HNR Associates, we offer practical expertise in road design and rehabilitation, with team members experienced in designing road infrastructure across regional Victoria. Roads are complex systems with multiple components; however, the primary focus in most projects revolves around the pavement seal, subgrade layers, and adjacent table drains.

We understand road ownership responsibilities:

  • DTP (Department of Transport & Planning) - Major arterial roads and highways
  • Local Councils - Local streets and community roads

Our collaborative approach provides:

  • Geometric Road Design — ensuring safety and operational standards
  • Pavement Design — optimizing configurations based on traffic loads
  • Road Drainage Design — effective surface water management
Bulk & Earthworks Engineering Services

Bulk Earthworks

At HNR Associates, we offer expertise in bulk earthworks quantity estimation and the design of landfills and levee structures, supporting both local councils and private developers, including holiday parks and recreational facilities.

Our team provides:

  • Accurate volume calculations for cut and fill operations using advanced modelling tools
  • Design of landfill cells and capping solutions, ensuring environmental compliance
  • Design of levees and flood mitigation structures for asset protection
  • Site grading and contouring plans for optimal earthworks balance
Hardstands and Raft Slabs Engineering Services

Hardstands & Raft Slabs

Hardstands and raft slabs are commonly used in residential and light commercial developments as efficient and practical foundation systems. While standard configurations often do not require complex engineering design, accurate quantity take-offs and budget planning are essential for effective project delivery.

At HNR Associates, we provide:

  • Precise material quantity estimations for concrete, reinforcement, and sub-base layers
  • Budget planning and cost analysis aligned with project scope
  • Site layout planning for optimal slab configurations and construction sequencing
Cantilevered Balconies, Portal Frames and Trusses Engineering Services

Cantilevered Balconies, Portal Frames & Trusses

Cantilevered balconies, portal frames, and truss structures—such as gazebo-style outdoor spaces—are increasingly popular in residential developments for their aesthetic appeal and functional flexibility.

Our structural engineering services include:

  • Structural design and sizing of cantilevered balcony systems
  • Engineering support for portal frames and truss assemblies
  • Collaboration with designers to align structural framework with architectural vision
  • Practical framing solutions balancing form, function, and buildability
Driveways, Footpaths, Pram Crossings and Kerb Channel Engineering Services

Driveways, Footpaths, Pram Crossings & Kerb and Channel

These elements are often overlooked but play a critical role in the functionality, accessibility, and compliance of residential and commercial developments. At HNR Associates, we specialize in the design and documentation of these essential urban infrastructure elements for mid-sized new developments.

Our team ensures:

  • Compliant design layouts in accordance with local council and DTP standards
  • Efficient grading and drainage integration for surface water management
  • Accessibility-compliant pram crossings meeting DDA guidelines
  • Practical driveway design balancing constraints, movement, and appeal
