Bridge Assessment, Inspection & Design

Structural Inspection and Reporting

We undertake condition assessments that go beyond surface-level inspection—identifying early signs of deterioration, such as spalling, corrosion, or water ingress, and providing actionable recommendations for remediation or replacement. 
 

Our team has experience with a wide range of bridge construction types and spans, including: 

 
• Precast concrete bridges 
• Steel composite structures 
• Sheet pile with concrete deck bridges 
• Timber and masonry bridges 

We also assess the impact of service congestion (e.g. buried pipework and cabling) on structural performance and future maintenance access. 

Specialist Design for Complex Environments

From soft clay subsoils to constrained industrial settings, our bridge design services consider geotechnical, operational and environmental factors from the outset. We regularly provide solutions for sites with: 

• Limited bearing capacity or reclaimed land 
• Congested underground services or hazardous materials
• Ageing infrastructure requiring phased replacement or load reduction 

By integrating geotechnical engineering, structural modelling and practical constructability reviews, we help reduce risk, cost and delays throughout the project lifecycle. 

Sustainable Bridge Solutions

Arthian is committed to reducing embodied carbon and minimising disruption to ongoing operations. Where possible, we explore:

 
• Reusing existing bridge foundations
• Accelerated construction techniques
• Low-carbon materials and design alternatives
• Design for maintenance and deconstruction

This approach supports sustainability goals while also enhancing safety and cost-efficiency.

Proven Capability

Our team recently led the inspection and asset management strategy for a large-scale COMAH installation, covering numerous bridge structures across a 160-hectare site. The project addressed issues including water ingress, spalling, soft ground conditions, and congested underground services, all resolved through intelligent design, risk-based prioritisation, and sustainable foundation reuse.
