Expert Witness Services

Expert witness Richard Allitt Associates

To find out more about our Expert Witness Services please email Richard Allitt directly at richard.allitt@raaltd.co.uk

We provide constructive, practical advice on all matters within the urban drainage, flooding and hydraulic engineering industries for legal disputes, court cases and Public Inquiries. We provide specialist advice for a variety of complex 'what if' scenarios to determine both cause and prevention for flooding incidents.

Richard Allitt Associates have a team of highly experienced urban drainage specialists all of whom contribute to our expert witness work. However, there are few individuals with the experience of Richard Allitt who not only advises the industry but has helped to develop best practise. Richard's work is highly regarded with a leading judge remarking of him:

“I found him to be an impressive witness. His reports and evidence were careful, detailed and to my mind displayed impressive technical command and understanding of the issues.”

Flooding

We offer expert advice for all flooding issues, identifying the causes and mechanisms of the flooding. From this we can design and advise on solutions which can be developed to prevent repeat flooding incidents. 

Hydrology

We provide insight for significant hydrology matters around the country that is often crucial to the outcome of a case.  

Hydraulic Modelling

We bring clarity to the complex reality of particular sites with our close attention to detail and practical experience of hydraulic modelling. For the claimant they are unlikely to have the necessary specialist modelling information that they need. This usually means that they will either have to do their own surveys and build their own hydraulic models. The most straight forward response to this need is to employ an expert such as ourselves as both the information required and its interpretation is highly complex.

UAV Survey Services

Richard Allitt Associates has its own specialist Remote Aerial Survey service enabling it to carry out a range of surveys and inspections of flooded and other hard to reach areas. We use our UAVs or ‘drones’ to carry out aerial surveys which are extremely useful in being able to identify things such as ‘urban creep’ where hard landscaping has prevented water soaking away leading to flooding, or identifying ditches and embankments which are not observable from ground level.  

Employing an expert witness removes any subjectivity connected with a incident. Essentially hydraulic modelling for legal cases needs a very highly skilled modeller who can test alternative hypotheses and can provide clear plans and visualisations. 

Examples of our work can be found in the following case studies.
