Sunderland Strategic Transport Corridor, Tyne and Wear

Geotechnical excellence delivered for major structure in the North East on the Sunderland Strategic Transport Corridor.

Aarsleff Ground Engineering were appointed in July 2019 by Principle Contractor Esh Civils to deliver a geotechnical works package as part of the Sunderland Strategic Transport Corridor project on behalf of Client Sunderland City Council. A significant number of retaining structures including 85m of contiguous bored pile retaining wall, 65lm retaining wall founded on CFA piles, a 250m long x 12m high Soil Nail wall and a large King Post Retaining wall encapsulating the existing 10m high retained wall pinned with ground anchors, were necessary to create space for the highway between the Pallion Shipyard and the upper existing highway and Tyne & Wear metro line; the latter borders the southern side of the land but at a much higher level.

Aarsleff’s senior geotechnical consultant Dr. Dan Adams said: “We were delighted to carry out these challenging geotechnical works. Delivering a contiguous bored pile wall combined with a large soil nailed retaining structure and the permanent anchors required close team work and good communication with our Client and Client’s team”.

King Post Anchors Investigation commenced in August 2019, with Aarsleff Ground Engineering installing and testing 3No. investigation trial anchors to confirm the ultimate bond stress at the rock/grout interface of the old Quarry. Anchor loads in excess of 4000 kN were successfully proven during these trials. The results were used…
