Covermeter Roped Access

The Span Engineering team has an extensive background in difficult access structures inspection across the globe, working on complex projects on some of the world's tallest buildings, landmark bridges, and architectural structures; all with their own unique access problems.

We carry out visual and tactile inspections, combined with investigative techniques such as covermeter surveys or UTM gauging, material sampling such as core drilling and carbonation testing, along with NDT techniques such as half-cell potential testing. We work with partner companies to provide sampling and materials testing services, and produce in-house inspection reports in hard and electronic copy with CAD drawings and extensive photo records.

We specialise particularly in large and unique structures, those with unusual access problems, major landmark viaducts, and more complex structures such as moveable bridges. Many of the structures we have worked on are heritage listed or have other constraints requiring a unique access solution.

We can supply a complete examination package, including boat cover, pontoons, MEWP's and other ancillaries, or work alongside our client's own staff to provide safety supervision and assistance with their examination requirements.

Bridge Inspection

Roped Access Bridge Inspection

We carry out road, rail and pedestrian bridge examinations throughout the UK, working on single arches to multi-span viaducts in all material types. We have worked on suspension, cable stayed, masonry, concrete, metal and moveable bridges around the world.

We have been carrying out difficult access bridge examinations on the UK rail network since 2003. Our key staff are NR STE 4 qualified, IRATA Level 3 supervisors and confined spaces certified. We carry out Examinations for Assessment, Detailed Examinations, and Additional Examinations on over, under and intersection bridges across the rail network. We perform Principal and General Inspections on Highway structures, and inspections of aqueducts and overbridges on waterways.

For all bridge works we prefer wherever possible to use innovative techniques to minimise road closures or rail possessions.
