Greenwich Peninsula Riverside Phase 2, Enabling Works
VolkerGround Engineering was awarded the design and construct project by sister company VolkerFitzpatrick, to install retaining walls across a planned area of the Greenwich Peninsula; known to have extensive underground obstructions caused by a former power station.
The close proximity of existing residences and the location of sensitive services, particularly the Thames Water Rising Main; running along one of the site boundaries, meant a silent vibration-less installation method was required for the piling works. Away from these locations, a conventional ABI hydraulic piling rig, with a vibratory hammer was employed.
The ground conditions and obstructions caused by redundant foundations from the former power station presented significant challenges to the piling work. This entailed excavation and removal by VolkerFitzpatrick to depths up to 6m below ground level. The site was also identified as a source of unexploded ordnance from the Second World War, which had to be investigated before site works could commence.
Close co-ordination with VolkerFitzpatrick ensured that programme delays, due to the extent of obstructions, were minimised and plant was utilised to its fullest extent.
Just a single tube stop from the financial district of Canary Wharf, Greenwich Peninsula is being developed to become a thriving district outlined by 1.6 miles of waterfront. 10,000 homes will combine with 48 acres of open spaces, and a commercial district encompassing 3.5 million square feet of retail, hotels, schools and public facilities. The regeneration of the area has already been established with the O2 Arena, the Ravensbourne College and the Emirates Air Line cable car extending to the Royal Docks on the north side of the Thames.
