RAIL & TRACKSIDE SERVICES

RISQSlogoColourCET’s success in achieving Railway Contractor’s Certification from Network Rail is further evidence of our commitment to quality, health and safety and adds to the RISQS (Link Up) qualification achieved back in 2013. Since obtaining the original Link-up status, CET have carried out more than 150 rail infrastructure projects.

Established in 1987 as a provider of materials quality assurance testing to the construction industry; CET have since established a reputation for quality service and excellent value. We expanded our capabilities to include integrated ground risk management solutions in 2012, with the addition of geotechnical and environmental consultancy, supported by in-house investigation services. By the following year we had expanded our trackside services offering further, to include high-quality drainage evaluation and surveys.

Independent certification and accreditation forms a key part of our strategy of continuous improvement and provides an additional level of confidence in our ability to deliver within the physically constrained environments that are typical within the rail environment. Adherence to the RCC code ensures we are compliant with the Sentinel Scheme rules, maintain RISQS accreditation and provide the training necessary to ensure site work is carried out to a high standard.

 

GEOTECHNICAL CONSULTANCY

Our dedicated team of geotechnical consultants are experienced in providing technical advice on a wide range of issues affecting the rail industry. For more than 20 years they have been providing expert analysis and consultancy on the design of foundations for buildings and structures (such as UTX, URX, station platforms and signal gantries), slope stability assessments, track foundations, drainage design and earthworks design.

ENVIRONMENTAL CONSULTANCY

Our environmental consultants are on hand to provide technical services and advice throughout the lifecycle of your construction project. The team provides a range of professional services, including: contaminated land surveys during the planning phase; waste classification and acceptance criteria testing during construction; remediation strategies, validation testing and advice on management of leaks and spills while sites are operational.

SITE INVESTIGATION

Our engineering team has extensive experience of managing and carrying out site investigations for a range of rail infrastructure projects. We leverage this expertise to develop the competency of our drilling crews.
In addition to conventional shell and auger boring services, our crews operate a range of specialist, lightweight and portable equipment for undertaking ground investigations within the physically constrained sites that are typical within the rail environment.

STRUCTURAL SURVEYS

CET technicians are experienced in investigating all types of structure; from concrete and brick to steel framed and post-tensioned. Our teams are experts in on-site data acquisition and utilise a wide range of techniques, including: half-cell potentials, Ferroscan re-bar mapping, concrete sampling and coring for strength analysis and chloride impregnation profiles.

Forensic analysis of structures is also undertaken and includes crack monitoring, tilt, orientation and vibration; using both traditional, on-site, and remote investigation methods. Our unique “bridge bash” sensor can detect an impact to a structure with instant notification via SMS or e-mail. This innovative feature provides a crucial early warning of a potentially hazardous situation.

DRAINAGE & UNDERGROUND UTILITY SURVEYS

Our specialists utilise state-of-the art technologies to carry out surveys of surface water, foul water draining systems and underground utilities for rail facilities; including stations and depots. Bespoke reports include detailed analysis and recommendations based on CCTV system surveys, sonar detection and CAD drawings for drainage maps.

Utility surveys are carried out in accordance with PAS 128 using multiple detection techniques – such as Electromagnetic Locators (EML) and Ground Penetrating Radar (GPR).

PAINT AND COATINGS SURVEYS

CET also provides a complete solution for condition surveys of paint coatings; including paint inspection, coating condition surveys, paint testing, failure analysis, quality control and document review.
