Centara Achieve RISQS (Rail Industry Qualification Scheme) Approval

risqs approvalCentara have achieved RISQS (Formally known as Link-Up) approval, enabling us to undertake surveys and non-intrusive investigation on Network Rail projects.

RISQS, formerly known as Achilles Link-up, has been developed to provide a service for the qualification of suppliers for all products and services that are procured by the industry.

RISQS supports Network Rail, LUL/Transport for London, passenger, light rail and freight train operators, rolling stock organisations, main infrastructure contractors and other rail products and services providers in the management of supply chain risk. RISQS is an independent, third party qualification assessment of a supplier's capability to supply products and services.

Centara's Link-up codes are:

  • 04.18.02 SER Non-intrusive
  • 04.66.08 SER Land Surveying

The award sits alongside some of our existing accreditation and certification of our team to enable us to undertake survey works rail environment.

Centara have been awarded full membership to the EuroGPR (The European GPR association)

EuroGPR, an association made up of users and manufacturers of GPR equipment, intent on raising standards within the GPR industry and looking out for the rights of our members, giving them voice at a pan-european level on matters such as licensing, health and safety and market access.

GPR stands for Ground Penetrating (or Probing) Radar. The technology is very similar to traditional radar but uses a shorter wavelength, to:

  • Locate buried pipes & services underground
  • Find evidence for other buried potential hazards e.g. mine shafts; voids
  • Investigate concrete structures to determine the position of reinforcement &/or the quality of the concrete & whether it contains voids
  • Check on the integrity of road subsurfaces
  • Investigate environmental conditions both natural (geology) & man-made (e.g. pollutant spread)
  • Learn about glaciers, their formation & structure
  • Uncover forensic evidence including buried human remains & weapons
  • Locate, Identify & Investigate Archaeological Sites


Underground utilities can now be detected more easily with new standard

pas128BSI, the business standards company, has collaborated with the Institution of Civil Engineers (ICE) to develop PAS 128, Specification for underground utility detection, verification and location.

As the demand on the nation’s infrastructure continues to grow due to new developments, the need to replace and/or maintain existing utilities increases. It is therefore essential that accurate information about where underground utilities are actually located is available.

Historically this has been hard to achieve as the detection, verification and location of utility assets have been subject to interpretation and inaccuracies. This has led to the safety of workers and the public being put at risk, unnecessary work that has often needed to be aborted, damage to third party assets and inefficient design solutions.

PAS 128 aims to provide a clear and unambiguous provision for those engaged in the detection, verification and location of active, abandoned, redundant or unknown utilities. It is applicable to surveyors, geophysicists or subsurface utility engineers as well as engineers, constructors, project managers and utility owners who are responsible for recording information about underground utilities.

Anthony Burd, Head of Market Development for Construction at BSI said: “The application of PAS 128 is not just restricted to current solutions, but will afford as yet unrealized benefits. For example, the use of remote robotic techniques to maintain asset networks in busy highways in future to reduce the need for intrusive maintenance practices (road excavations). Similarly, accurate mapping of utility networks could improve asset modelling capabilities with more determined outcomes.”

Centara Achieve Achilles UVDB Verification

uvdb-logoCentara has been awarded UVDB Verify Status under the Achilles Utilities Vendor Database (UVDB) scheme.

The UVDB B1 Verify Scheme is essentially a mechanism for supplier pre verification and assessment, and is applicable for contracts of high operational risk. Achilles UVDB Verify service provides organisations with a measure of demonstrable Safety, Health, Environment & Quality (SHEQ) capabilities and gives a clear understanding of the industry’s requirements.
