GE Awards 2020

Aarsleff are delighted to have been shortlisted in the Ground Engineering Awards 2020 for UK Geotechnical Project valued under £500,000.

The shortlisted project features Aarsleff’s geotechnical solution to stabilise a failed section of the coastal retaining wall outside the famous Gibraltar Rock Pub above King Edwards Bay, Tynemouth. The cliff face had been remediated poorly in the 1980’s and was in imminent danger of collapse, threatening local pubs and restaurants on the beach and the cliff, as well as Tynemouth Priory, one of the North East’s most iconic landmarks.

Aarsleff’s Specialist Geotechnical Director Jonathan Proctor commented on the shortlisting, saying,

“It is great to see our retaining wall project in Tynemouth shortlisted for the GE Awards 2020! This project showcases our capabilities in delivering a complex and specialist geotechnical solution in such an iconic part of the North East – a project that deserves the recognition of everyone involved.”

Project Details

Aarsleff, acting as main contractor for North Tyneside Council and principal designer Capita, designed and self-delivered the geotechnical aspects of the works across two phases. With early engagement, Aarsleff carried out the ground investigation works to determine the nature of the cliff failure and to enable the design of a cost-effective solution that would meet the required design life of 120 years.

Phase two saw Aarsleff implement the solution, installing 19 No. 300mm diameter mini piles to depths of 11m to create a permanent contiguous piled wall and capping beam. A crash desk was then set up on the slope and the 3m of the existing failed wall was excavated to reveal the piled wall and create a platform.

The gabion face was spray finished with shotcrete, which was carved and dyed to blend in with the existing Victorian wall. The area was finally cleared with railing reinstated ready to be reopen to the public.

Aarsleff’s Geotechnical Contracts Manager Jack Doran said,

“This project has been extremely successful. We were able to overcome the complexity and size of the project by working closely with the North Tyneside Council and principal designer Capita throughout the tender and delivery stages. The packaged solution we installed was value-engineered to meet all the safety and design requirements, whilst providing cost-savings for the client.”

Aarsleff Ground Engineering now move to the second stage of judging to deliver a presentation at the Ground Engineering Magazine’s head office in London. The winners will be announced at the grand awards ceremony on the 11th June at Grosvenor House Hotel in London.
