Nicholls Colton – Bridges

Bridge Inspections

Nicholls Colton Group has been carrying out the specialist inspections and investigations necessary to protect, maintain and upgrade the UK’s vast stock of road and rail bridges for over 30 years. From medieval masonry arch to modern post-tensioned box-beam and composite bridges, our investigations have covered the full range of the UK’s bridge infrastructure.

Working closely with major contractors, stakeholders, consultants and government agencies, we can provide the technical staff and specialist equipment required to carry out this often complex and demanding work.

With a team of highly experienced engineers and technicians, Nicholls Colton Group offers an extensive range of testing solutions which allow us to investigate almost any component of any bridge structure. Our focus on client engagement allows us to tailor our testing to match and regularly exceed the objectives of the testing program. This often requires the development of our own bespoke investigation proposals when presented with difficult access or technically challenging projects.

If the analysis of site samples is required, Nicholls Colton Group’s fully equipped *UKAS accredited testing laboratory No. 0320 and *MCERTS accredited laboratory can undertake a wide range of materials testing and geotechnical analysis.

Once the results of in situ surveys and laboratory analysis have been collated, tailored factual or interpretive reports are issued to our clients.
