Steel & Stone | Civil Engineering Experts

We deliver solutions that respond to unique site conditions, satisfy council and regulatory requirements, and support efficient construction sequencing.

By prioritising sustainability and resilience, our civil designs reduce whole-of-life costs, minimise environmental impacts, and ensure developments are both practical and future-ready.

Capabilities

Residential + industrial subdivisions

Comprehensive civil engineering design for greenfield, brownfield, residential, commercial and industrial land developments.
Services include site planning, road layouts, utility coordination, bulk earthworks, stormwater management and statutory approvals.
Ensures compliant, constructable and cost-efficient subdivision outcomes aligned with local council, state authority and utility provider requirements.
Full documentation, certification and design coordination from concept to construction.

Bridges & Earth Retaining Systems

Structural and civil design for small to medium-scale bridges, culverts, pedestrian structures and access crossings.
Design of earth retaining solutions including reinforced soil walls, gabion structures, bored pile walls, precast systems and mass-gravity walls.
Focus on long-term durability, constructability and compliance with Australian Standards and authority requirements.
Ideal for subdivision access, overland flow crossings, major earth cuts and difficult terrain.

Bulk earthworks modelling + quantity calculations

Detailed 3D earthworks modelling to optimise cut-fill balances and minimise export/import volumes.
Accurate material take-offs for tendering, construction planning and cost estimation.
Identification of high-risk geotechnical and topographical constraints early in the design process.
Supports subdivisions, building platforms, industrial lots and major civil infrastructure works.

Road + pavement designs for all road classifications

Design of local, collector, industrial and arterial roads in accordance with Austroads and council standards.
Pavement assessments and designs using flexible, rigid, heavy-vehicle and low-volume pavement systems.
Road geometry design including horizontal/vertical alignment, sight distances and safety improvements.
Complete drawing packages including long-sections, cross-sections, pavement details and construction specifications.

Carparks, driveways, ramps + road frontages

Functional and compliant design of commercial, residential and industrial carparks.
Design of driveways, access ramps, circulation layouts and vehicle swept-path analysis.
Solutions that optimise traffic flow, safety, gradients and DDA compliance.
Road frontage works including verge upgrades, drainage, kerb & gutter, footpaths and service adjustments.

Stormwater drainage, on site detention, retention + reuse systems

Hydrologic and hydraulic design of minor and major drainage networks for developments of all scales.
OSD tank and basin design, including above-ground, below-ground, online and offline systems.
Retention, reuse and WSUD-integrated stormwater harvesting solutions.
Authority-compliant modelling, MUSIC integration and certification for DA, CC and subdivision approvals.

Erosion + sediment control plans (ESM)

Preparation of erosion and sediment control plans for construction sites in accordance with LANDCOM and local authority guidelines.
Identification of site-specific erosion risks, sediment basins, diversion drains, check dams and perimeter controls.
Provides contractors with clear staging and installation requirements to reduce environmental risk and ensure compliance.
Suitable for subdivisions, earthworks, commercial developments and infrastructure projects.

Water sensitive urban design (WSUD)

Integration of sustainable water cycle management principles into civil designs.
Design of bioretention systems, swales, raingardens, wetlands and permeable pavements.
Achieves stormwater treatment targets for quality, quantity, flow control and environmental health.
MUSIC-supported concept and detailed documentation for council + authority approval.

MUSIC modelling for stormwater quality control

MUSIC modelling for stormwater pollutant load reduction, WSUD sizing and authority compliance.
Supports DA, CC and subdivision approvals requiring water quality treatment systems.
Provides optimised designs integrating raingardens, bioretention basins, wetlands, GPTs and proprietary systems.
Clear reporting, sensitivity testing and justification of model parameters.

Construction phase supervision

On-site civil supervision to ensure works are constructed in accordance with approved drawings and specifications.
Inspection of earthworks, pavements, stormwater, utilities, retaining structures and roadworks.
Issue of compliance reports, engineering certificates, and authority sign-off documentation.
Early identification of construction risks, non-conformances and design issues to minimise rework and delays.
