  • All materials generated from the construction works were recycled and reused within the new works.
  • Cost savings were generated through non-occurrence of risk items and subsequent surfacing materials savings against allowance.


The scheme at RNAS Culdrose entailed the strengthening and overlaying of the main runway 12-30 and secondary runways 07-25 and 13-36 using grooved Marshall Asphalt, as well as the reconstruction of various taxiways utilising composite construction and pavement quality concrete solutions.

Aggregate Industries was employed as a cluster lead contractor, with principal contractor delegated responsibilities under the Construction Design Management Regulations (CDM) 2007. It was critical to our client that all parties worked in a collaborative manner ensuring a one team approach.

All construction works were carried out under phased possessions enabling the base to remain fully operational throughout the construction phase.


We were engaged at a very early stage working collaboratively with our client Debut Services during the design and evaluation phases. Through ECI we worked alongside our design partner RPS and were able to assist in all the initial site investigations by carrying out coring CBR testing and FWD testing to the existing pavements. We also completed a full CCTV survey of the existing drainage system and a full GPR, CAT scan and trial hole survey to determine the positions and depths of the existing services. A full topographical survey of all surfaces was also completed.

We were also able to identify issues with a layer of tar bound material present in the runway and taxiways and the presence of existing services, which were of insufficient depth and not identified from the existing information available.

These initial site investigations enabled us to propose pavement options and budget costings, including cost savings and programme solutions before the main construction activities commenced.
