Anchors, Contiguous Pile Wall and Soil Nails for a multi-million pound project is underway in Sunderland
With an estimated completion date of Autumn 2021, a multi-million-pound project to improve Sunderland’s road network is well underway, moving into the third of five phases. The project will create a dual carriageway through Pallion, running underneath the Queen Alexandra Bridge, into Deptford and onto the city centre and St Mary’s Boulevard. The contract will also deliver a comprehensive Social Value package which includes training and employment opportunities for local residents, support for local primary and secondary students, work experience placements for college and university students and a number of full-time jobs.
The £35.6M construction contract for phase 3 works was awarded to Esh Civils; the civil engineering division of Esh Construction. Andy Radcliffe, Esh Group’s Chief Executive said: “We have a proven track record of infrastructure delivery across a range of sectors and have established a first-class team of professionals to work with our client and our local supply chain to deliver this project”.
Aarsleff Ground Engineering were appointed by Esh to undertake the geotechnical works in early July. These works comprise the design and construction of a contiguous bored pile retaining wall, a large soil nailed wall and a ground anchor investigation trial.
Between August 7th to 30th August 2019, Aarsleff Ground Engineering installed and tested 3No. investigation trial anchors to confirm the ultimate bond stress at the rock/grout interface. Anchor loads in excess of 4000 kN have been successfully proven during the trial. The results shall be used to develop the permanent anchor design for the lower Pallion king post retaining wall.
