Lean methodology reduces resources throughout the process.
Robust data provides justification of interventions and asset condition.
Carnell have designed several survey and remediation packages which deliver quick and cost-effective solutions to improve the functionality of network drainage assets performance and extend their lifespan.
Working with the client, we provide a tailored approach which is data-led, to develop risk-based interventions on the network. We have a full range of solutions to identify and repair safety-critical structural defects, while providing post-construction information which can help to build future schemes.
The adaptable process is devised in collaboration with the client to navigate each contract’s commercial / value management challenges to have the most effective benefit to road-users.
Areas of missing condition data is correlated against flooding hotspots. A jetter-led survey programme is developed which supports the 3D VM stage-gate process. The emphasis on pipe-cleansing clears blockages and facilitates additional survey data to develop future schemes.
In areas of persistent flooding and little condition data, survey and remediation teams are mobilised in the same road space. Where safety-critical defects are identified, proposals are discussed with the client and interventions swiftly undertaken using trenchless or invasive techniques.
Desktop surveys identify the need for intervention with a targeted approach. Condition assessments of the asset and remediation proposals are provided to the client. The drainage scheme is then developed through ECI and quickly mobilised. This can also be applied to the wider asset such as ponds, ditches and soft estate using SmartScan and HDAGPR condition data.
This web-based GIS interface holds asset inventory, condition and several other relevant datasets.
The user-friendly platform can be accessed by authorised users to highlight areas for concern, prioritising further investigation or for scheme identification and development.
Drainage Viewer is a geographical information system (GIS) that holds the network intelligence, gathered from several sources and can provide correlation between incidents and drainage condition. It helps build the programme and give cost-certainty.
Find & Fix survey data is available 24/7 through the interactive online portal.
The Data – Check – Fix approach is our asset management methodology which relies on desktop surveys to target areas most at risk and guide the positive interventions.
This removes the need for detailed design which prolongs the process, but also provides reliable survey data on the functioning asset which aids buildability of future schemes.
