Risk Based Asset Management (RB&M) optimises the budgets are spent in the provision and/or maintenance of new and existing infrastructural elements/networks.

 

Adoption of a risk based approach ensures that those actions/decisions which have the greatest effect on the overall operational efficiency/performance of the system, in terms of whole life performance, are prioritised in a robust manner which is beyond the capabilities of traditional deterministic approaches.

Weigh-in-Motion (WIM) is used to describe methods used to measure vehicle axle weights while the vehicle is moving at highway speeds.

 

WIM systems are increasingly used to collect data on bridge loading, which is essential in any calculation for any bridge safety in service. There are primarily two categories of WIM systems, those which consist of a system of sensors embedded in the road surface, (pavement based systems) and those consisting of sensors underneath the bridge (Bridge WIM systems)

Many companies have extremely powerful computer models to predict the response of bridge structures to applied loading. However, the loads themselves are far less certain and this is a field that RODIS has particular expertise in. What the standards specify is only part of the story. 

ROD-IS has particular expertise in closing the gap between what data is available and what the bridge owner/operator needs to know. In the specification of SHM systems we ensure that the valuable and usable results are extracted.

 

ROD-IS can also provide road owners and administrations with the necessary advanced technical back-up to plan sensor schemes and to analyse the output for SHMMany bridges have deteriorated over the years and have reached the point where they no longer meet the standard specified in codes of practice whilst others have simply outlived their design lives.
