Nicholls Colton – Highways Investigation



The UK’s vast road network is in constant need of maintenance, refurbishment, upgrading and replacement. Identifying the need for and extent of such work requires a thorough understanding of road construction and its current condition.

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 our team of highly experienced engineers and technicians, Nicholls Colton Group offers an extensive range of testing solutions which allow us to investigate the construction and condition of the country’s roads and their furniture. Our focus on client engagement allows us to tailor our testing to match and regularly exceed the objectives of the testing program.

Our managers and technicians are trained under the New Roads and Street Works Act (NRASWA). Training courses in this category are designed for Supervisors and Operatives who are required to carry out their duties to the standards prescribed by City & Guilds in-line with the New Roads and Street Works Act, current legislation, and applicable Approved Codes of Practice (ACOP’s).

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