Bridge Inspections, Assessment & Strengthening Design
Specialist Bridge Inspections, Structural Assessment & Strengthening Design
Arthian delivers comprehensive bridge inspections, structural assessments and strengthening design for industrial, energy, utilities and COMAH facilities, helping clients manage critical bridge assets throughout their lifecycle. We support asset owners from condition surveys and load assessments through to remediation, strengthening and life-extension strategies.
Our engineers work across steel, concrete, masonry and composite bridge structures, providing clear, risk-based reporting and practical engineering solutions that help keep industrial operations safe, compliant and operational.
We provide a complete end-to-end service covering:
- General, principal and special bridge inspections
- Condition surveys and defect identification
- Structural assessments and load capacity evaluations
- Fatigue, stability and durability assessments
- Bridge strengthening and remediation design
- Extension-of-life strategies
- Bearing, joint and foundation assessments
- Access planning for complex industrial environments
- Asset management support and investment prioritisation
Our reports provide clear, actionable recommendations that help asset owners make informed decisions about maintenance, repair and future investment.
Why Bridge Inspections Matter
Bridges are safety‑critical assets. Ageing, increased loading, environmental exposure and historic design standards all contribute to deterioration. Regular inspections ensure:
- Structural safety and stability
- Compliance with national standards
- Early identification of defects
- Optimised maintenance and investment planning
- Reduced risk of unplanned closures or failures
Arthian provides Category 0–3 inspections, structural modelling and strengthening design for simple and complex structures.
Our Bridge Inspection & Assessment Services
Arthian provides a complete end‑to‑end service covering:
General & Principal Bridge Inspections
We undertake inspections aligned with national standards, delivering:
- General Inspections (GI)
- Principal Inspections (PI)
- Special Inspections (SI)
- Access‑challenged inspections using MEWPs, rope access or drones
- Defect identification, mapping and prioritisation
- Photographic and condition‑grade reporting
Our reports provide clear, actionable recommendations for asset owners.
Structural Assessment & Load Capacity Checks
We assess structural capacity using:
- Eurocode‑based structural modelling
- Load rating and assessment for increased traffic or plant loads
- Assessment of abnormal loads
- Fatigue, deflection and stability analysis
- Assessment of scour, settlement and foundation performance
Our engineers provide practical strengthening or restriction strategies where required.
Strengthening, Remediation & Life‑Extension Design
Where inspections identify deterioration or insufficient capacity, we deliver:
- Steel strengthening (plates, stiffeners, section enhancement)
- Concrete repair and strengthening
- CFRP strengthening for beams, slabs and decks
- Bearing replacement and refurbishment
- Parapet upgrades and safety improvements
- Waterproofing, drainage and corrosion‑management design
- Temporary works and construction sequencing
Our designs minimise disruption and extend asset life safely and cost‑effectively.
Bridge Replacement, Upgrade & Brownfield Integration
For structures at end‑of‑life or requiring major upgrade, we provide:
- Feasibility studies
- Replacement bridge design
- Temporary works and propping
- Demolition planning
- Integration with existing infrastructure
- Staged construction and traffic management planning
Spotlight Case Study: Inspection & Assessment of 173 Bridges
Arthian delivered a major programme of 173 bridge inspections and structural assessments across a large, mixed‑estate network. The project included:
- General and Principal Inspections
- Detailed defect mapping and prioritisation
- Structural modelling and load assessments
- Risk‑based maintenance planning
- Strengthening and remediation recommendations
- Clear, portfolio‑level reporting for investment planning
This programme provided the client with a complete, actionable understanding of asset condition, enabling targeted investment and improved safety across the network.
Types of Bridges We Inspect & Strengthen
We provide inspection, assessment and strengthening services for bridges located within:
- Industrial facilities
- COMAH sites
- Manufacturing plants
- Chemical and process facilities
- Energy and power generation sites
- Utilities infrastructure
- Ports and marine terminals
- Private industrial estates
This includes steel, concrete, masonry and composite structures, as well as specialist industrial bridge assets integrated within wider operational infrastructure.
Safety‑led
We prioritise safe access, safe inspection methods and clear risk communication.
Evidence‑based
All assessments follow Eurocodes, DMRB, BD standards and industry best practice.
Practical
Our strengthening designs are buildable, cost‑effective and aligned with operational constraints.
Lifecycle‑focused
We support long‑term asset management, not just one‑off inspections.
