Kingsbridge Quay Project Completed

Home » News » Kingsbridge Quay Project Completed

In October 2018, Landmarc was contracted by South Hams District Council to undertake the demolition and rebuilding of approximately 60 meters of the old quay wall at Kingsbridge. Due to the nature of the site being tidal, this created implications for periods of work. However, Landmarc designed a temporary work system of sheet piles which gave an extra hour on either side of the tide. This enabled work to continue for longer periods. New foundations were cast up to 1.5 meters deep below the bed level of the estuary and foundations were poured in 4 sections.

Timings were critical and tolerances were minimal. On completion of the foundations, approximately 300 cubic meters of concrete had been poured, with a tolerance of 6mm. Precast concrete units were then placed and fixed on the foundations, which enabled a new concrete wall to be faced with natural stone. This was then backfilled and compacted to the engineering specification. Finally, copings were fitted, and new footpaths and dwarf walls were constructed. In addition, an area of the car park was removed and re-laid to complete the work to the quay wall. The site was reopened in time for Easter 2019. This is the second quay wall project that Landmarc has completed in the South Hams.
