You can rely on our programme of innovations to make things safer, smarter and more efficient. That applies whether we’re revolutionising the speed and cost of drainage surveys, dramatically extending the range of continuous GPR scanning, deterring dangerous driving, cutting vehicle movements and emissions in roadside filter drain refurbishment, reducing hazardous stone scatter, or providing vital asset management information
Carnell have developed a revolutionary drainage survey resource for fast and cost-effective highway asset management.
Focusing on the most relevant asset and condition information a streamlined site team can work under IPV to collect GPS and CCTV data thereby increasing survey lengths by 300% whilst still enabling HADDMS compatibility.
FastTrack is less than half the cost of a traditional CCTV survey and improves roadworker safety by reducing their time on the high speed network and utilising custom-built Survey & Welfare vehicles which are accessed further from live running lanes.
Launched in 2012, SMARTscan was developed to provide a quicker, safer and more cost-effective indication of filter drain condition. Ground Probing Radar is utilised in a unique way to indicate the porosity of filter drains, and when combined with vacuum-extracted samples, and video of the surface gives a comprehensive condition assessment.
SMARTscan is a rolling survey, allowing lengths of up to 40km to be surveyed in one shift; under the protection of an IPV instead of a static lane closure.
Unlike trial holes at regular intervals, SMARTscan gives continuous data for the full length, is safer for the road worker and offers best value for the client.
Utilising the latest camera technology to deter dangerous driving around work sites.
Successfully trialed on the HA network in 2014 SMARTcam uses police approved ANPR and analogue cameras to capture footage and number plates of drivers entering our work areas.
The equipment used is identical to that used by the police. Fully watermarked footage, with SHA-2 AES 256 authentication, enables prosecutions to be made.
Proven to significantly reduce the number of ‘vehicle associated’ near misses at sites where it’s deployed, the visual deterrent can operate in the day and night.
A market first in providing on-site refurbishment of roadside filter drains.
By recycling the filter media in-situ, only material not conforming to Type B specification is removed from site, whilst drains are left functioning fully.
Fewer HGV transfers, minimal import from quarries & loads to landfill ensure that the STONEmaster process is both an environmentally sustainable and cost-effective method of prolonging asset lifespan.
Filter drains operating at their optimum performance level effectively remove surface run-off and sub-base moisture, to ensure roads are safer and last longer.
A portable method of surveying drainage pipes regardless of their location.
For when access is restricted or connectivity is the main focus of the CCTV condition survey, Carnell’s SMARTview cameras provide a snap-shot of the piped asset condition. A quick, safe and cost-effective solution, the fully mobile pole-mounted camera is controlled by a hand-held tablet giving a clear image of up to 40m down a pipe or culvert.
SMARTview minimises Traffic Management costs often removing them altogether if off-network parking can be secured, meanwhile safety is improved as the need for confined spaces entry is eliminated.
Eliminating vehicle embedment and reducing stone scatter when vehicles stray on to roadside filter drains.
Independently approved by TRL (Transport Research Laboratory), STABLEdrain was successfully introduced in to filter drain refurbishment programmes in 2003.
StableDrain significantly improves road user safety and reduces managing agent clean-up costs, by allowing errant vehicles to maintain control when they drive on to a roadside filter drain.
Adopted within the HA Advice Note 217/08 ‘Alternative Filter Media and Surface Stabilisation Techniques for Combined Surface and Subsurface Drains‘.
Carnell first undertook drainage asset inventory and condition surveys on the highways network in 2005. Our pioneering service was the first to comply with HD43/04 and SD15/03 standards and be uploaded to HADDMS, Highways England’s drainage database.
Since then Carnell have remained at the forefront of the industry, developing our offering to provide Full Asset Detailed Defect Surveys, Connectivity Surveys and FASTtrack surveys on the carriageway assets as well as specifically on Balancing Ponds, Outfalls & Culverts.
Through investment into the latest technologies and development of our in-house teams, Carnell still provide the most reliable and complete drainage solution.
