A prioritised find and fix drainage solution to prevent network flooding.

Traditional Full Asset Detailed Defect Surveys (FADDS) are used to undertake drainage investigations ahead of schemes or investment decisions, enabling an accurate build-up of the scope of works.

FloodPrevent surveys help asset holders to quickly collect critical drainage inventory and condition data, enabling them to make informed decisions regarding targeted interventions and ongoing maintenance.

The problem

Lack of drainage condition data, leading to lack of proactive maintenance and long term asset management planning.
Existing survey process Full Asset Detailed Defect Surveys (FADDS) is slow and expensive but required to gain funding through the Value Management process.
Flooding events can close the strategic road network, cause disruption to customers and damage HE reputation.
Excessive carriageway surface water can cause serious road traffic accidents.
Poor drainage maintenance can shorten the life of other assets, e.g. pavements and embankments.
• Network access is difficult due to the large amount of roadworks on the network

Plan & implementation

LEAN review of the FADDS process to eliminate waste and add value.
Development of a new process to reduce the standing time of camera crew.
Provision of a full length survey to identify all structural defects.
Integration of routine maintenance into the process.
Targeting of areas with poor drainage/flooding hotspots or lack of condition inventory.
Development of a multi-purpose vehicle to reduce the number of vehicles on site.
Integration of surveys with other works, to enable shared TM.

Reporting

FloodPrevent survey data is available 24/7/365, on-site or in office, via the online Interactive Drainage Viewer.
