PROJECT IN PROGRESS: Riverside Drive, Aberdeen

Riverside Drive Underpass Aberdeen


  • Acting as main contractor for Aberdeen City Council
  • 4m high x 5m wide OMO Flood Gate to protect underpass
  • Due for completion August 2017

Aberdeen City Council (Structures, Flooding and Coastal Engineering Department) contacted UK Flood Barriers in June 2016 for some initial feasibility advice on a flood defence solution to protect an underpass at Riverside Drive, Aberdeen. During flooding events, water from the swollen River Dee surges through the underpass flooding local businesses and residential properties.

After full consideration UKFB Engineers confirmed the project was entirely feasible, however, given the nature of the environment; a completely bespoke Flood Gate design would be required.

Initial concept drawings, including a 3D visual, were produced for a double leaf, mitred swing hinge steel Flood Gate. The solution was specifically designed to seal at the head of the Gate to provide full height flood protection. The finished Gate would measure 4m high by 5m wide.

As part of the design development process, UKFB also advised the Council team on PAS 1188 requirements and what leakage rates they should be seeking.    

To maximise project delivery efficiency, UKFB proposed it would undertake the project as a full design and build package, acting as main contractor and completing all structural and civils design in house.

Over a 10 week period from December 2016, UKFB made its tender submission and was formally awarded the project in April 2017 after a comprehensive tender evaluation process.

The Aberdeen project, the first to ever appoint a flood sector company as the main project contractor, will see UKFB undertake the survey, design, manufacture, civils/drainage construction and steel flood gate installation, in-situ water spray testing, client training and final completed project handover.

Whilst the project is unique, representing the first ever attempt in the UK to deliver a fully protected, closed off tunnel/underpass, the UKFB team is confident it has the experience and knowledge to deliver this, Aberdeen Councils ‘pilot’ Riverside Drive project, and potentially more projects as they are ‘rolled out’ in the future.   

Work will commence on site during the first week of June and will be completed in late August. Progress will be recorded by way of a permanent time-lapse camera so ensure this unique flood defence installation is visually documented.
