Public Safety Risk Assessments & Initial Need Assessments for Screens

Client: Amey Consulting / DFI                                                     Location: Northern Ireland


In 2021 we were commissioned to undertake a large scale site inspection project with Amey Consulting on behalf of DFI in Northern Ireland. Our task was to visit a number of sites to provide a Public Safety Risk Assessment (PSRA) and an Initial Need Assessment for a Screens (INA). We have been assigned:

· 2,000 Initial Need assessments for unscreened inlets and outlets

· 2,000 PSRA’s for every Inlet/Outlet

· 667 PSRA’s for Fluvial Defences

· 43 PSRA’s for Coast Defences

Health and safety are at the forefront of all our projects. We have assessed the risk associated with the tasks required and identified that lone working will be viable for the majority of the assets using our lone working process. This requires a lone inspector to text or call a nominated office contact every hour. The inspector will also be carrying an iPad to complete the inspections that can be live tracked by the office-based health and safety team at any given point.

Some sites, such as the coastal defences, may come with increased risks to an inspector. To alleviate these, where lone working is not applicable we used two inspectors working together.


A team of JBA inspectors, working independently, will drive to each site, and walk the entire length of the asset to complete the risk assessments which is done through DFI’s power app. The assessments are then uploaded to a hosting website where a member of the office team can download the information and generate the final deliverable report. At each PSRA asset, the inspector will score each element required with a severity score (1-5) and a likelihood score (1-5) which will be used to calculate the risk factor at each site. Once this has been undertaken, the inspector will add potential improvements at each site such as security fencing, signage and handrails etc. before rescoring the severity and likelihood to create an improved risk factor.

Once the inspector has completed the PSRA, they will then complete the INA for each culvert inlet/outlet. The assessment will be undertaken on JBA’s iOS application, GISmapp. A host website will also be created to store, view, and edit the data collected on-site. Once the inspector has collected the required detail on-site, they can then upload it directly to the GISmapp hosting website to be viewed immediately by the office team who can begin creating the INA assessment reports.


Carrying out PSRA assessments at each asset will ensure that health and safety is being considered across every Flood Risk Asset in Northern Ireland. This will also ensure any person working at the site, or any member of the public that accesses the site, will be safe to do so – and if the site is deemed unsafe, signage will be in place to warn them of the dangers. Adding improvements to the reports at each site will also allow the client to better understand what is required to ensure it is safe. This provides great efficiencies for the client when carrying out improvement works.

Initial Need Assessments are vital at inlets and outlets for flood risk purposes as well as health and safety. Adding a screen to an inlet can reduce the risk of blockage and damage caused by debris entering a culvert. Screens also prevent people from entering the culvert, which makes each culvert a safer asset. Using GISmapp to collect the site data also means any issues with the inlets and outlets noted on-site can be reported back to the client almost immediately after being uploaded.
