CONSTRUCTION PERIOD August 2019-January 2021
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.
With existing land falling steeply across the site, and large industrial facilities to be negotiated, retaining structures and slope stabilisation works were key to making this possible along with an historic backfilled Quarry which the old shipyard have been constructed on.

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.
