Civils & Structures
Arthian provides practical, buildable and cost‑effective civil and structural engineering solutions for infrastructure, industrial and energy projects across the UK and Ireland. Our teams integrate civil engineering, structural design, geotechnical insight and construction‑phase support to help clients deliver safe, compliant and efficient works on complex sites.
We support projects from early feasibility through detailed design and construction, delivering coordinated engineering that reduces risk, improves constructability and supports programme certainty.
Civil Engineering Design
Our civil engineers deliver robust, technically sound designs for a wide range of site infrastructure and enabling works. We focus on solutions that are safe to build, easy to maintain and aligned with regulatory requirements.
Capabilities include:
- Access road and track design
- Pavement and hardstanding design
- Earthworks design and cut/fill optimisation
- Site layout, levels and grading
- Drainage interfaces and outfall structures
- Bellmouths, junction improvements and tie‑ins
- Construction compounds and laydown areas
Our designs integrate seamlessly with geotechnical, drainage, environmental and temporary works requirements to ensure a coordinated approach across the project.
Culvert Design & Assessment
Culverts and watercourse crossings are critical elements of site infrastructure, particularly for industrial, energy and linear projects. Arthian provides design, assessment and upgrade solutions for new and existing culverts.
Services include:
- New culvert design (box, pipe, arch and bespoke forms)
- Structural assessment of existing culverts
- Hydraulic capacity checks
- Scour and erosion risk assessment
- Headwall and wingwall design
- Condition surveys and remediation strategies
We ensure compliance with environmental, flood risk and permitting requirements while delivering durable, low‑maintenance solutions.
Retaining Walls & Structures
Arthian designs retaining structures and small civil structures that support safe and efficient site development. Our engineers work closely with geotechnical specialists to ensure stability, durability and constructability.
Capabilities include:
- Gravity, reinforced soil and modular block retaining walls
- Reinforced concrete retaining structures
- Embedded retaining systems (sheet piles, king post walls)
- Headwalls, wingwalls and minor structures
- Slope stabilisation and earthworks interfaces
- Structural assessments and remediation design
We tailor solutions to site constraints, ground conditions and construction methodology, ensuring safe and efficient delivery.
Earthworks & Ground Interface Design
Effective earthworks design is essential for safe construction and long‑term performance. Arthian provides earthworks modelling and stability assessments that integrate with drainage, civils and structural requirements.
Services include:
- Cut/fill modelling and optimisation
- Embankment and slope design
- Settlement and stability assessments
- Ground improvement recommendations
- Interface design with foundations and structures
Our designs help clients reduce material movements, minimise cost and improve programme certainty.
Construction Support & Compliance
We support contractors and developers throughout the construction phase, ensuring designs are implemented safely and efficiently.
Support includes:
- Design queries and construction liaison
- Temporary works coordination (with our in‑house TW team)
- Site inspections and engineering assurance
- As‑built verification
- Value engineering and buildability reviews
Our integrated approach ensures smooth coordination between civils, geotechnical, drainage and temporary works disciplines.
