Our Capabilities

Underdeck Gantry Maintenance & Inspection

At Spencer Bridge Engineering, we deliver specialist maintenance and inspection services for underdeck gantry systems, ensuring safe, reliable and long-term access to bridge structures. Underdeck gantries are critical assets that enable the safe inspection and maintenance of bridge infrastructure. Our engineered solutions maintain performance, ensure operational reliability and support long-term asset management.

A key part of our capability is the delivery of planned inspection, maintenance and refurbishment programmes for underdeck gantries operating in demanding environments. Subject to continuous mechanical wear, environmental exposure and operational loading, these systems require proactive management to remain safe, compliant and fully operational. We provide structured maintenance regimes that sustain performance, extend service life and ensure continued access for bridge inspection works.

We carry out detailed structural and mechanical inspections to assess condition, identify defects and detect early signs of wear or potential failure. This proactive approach reduces operational risk, minimises unplanned downtime and ensures efficient, uninterrupted access to bridge assets. Where required, we also deliver fault diagnosis, servicing of mechanical and control systems, and targeted refurbishment works to restore and optimise performance.

Our steelwork strengthening and repair capabilities improve the performance and longevity of existing structures through load-capacity upgrades, fatigue and crack remediation and targeted corrosion treatment including steel section replacement where required.

Safety underpins every aspect of our delivery. Working in environments involving height, water and complex mechanical systems, all activities are carefully planned and executed within controlled conditions. This ensures the safety of operatives, inspectors and the public while maintaining system integrity throughout all operations.

Drawing on our multi-disciplinary in-house expertise, we integrate structural, mechanical and access engineering to provide comprehensive lifecycle support. Our capabilities include inspection and assessment, preventative and reactive maintenance, system servicing, refurbishment and upgrade planning, compliance assurance and integration with wider bridge maintenance strategies.

By combining technical expertise with proactive maintenance, we help clients protect access capability, reduce risk and maximise the value and longevity of their assets.
