Kaymac were contracted by O'Keefe Construction to undertake works to an existing wharf wall located off the tidal River Thames in Greenwich, London.
The works consisted of:
- Various wall repairs; including concrete placement, re-pointing, stitching and re-casing of brickwork.
- Core-drilling of the wall for a number of outlets and also ground anchor tendons.
- Installation of ground anchors through the wall and fixing to a concrete ground anchor beam.
- Installation of a timber fender system along the length of the wall which incorporated timber fenders with steel fixing brackets.
Kaymac obtained the necessary FRAP and associated EA consents to undertake the works.
Due to the tidal nature of the location, Kaymac gained access to undertake the works via a combination of mini cranes, man-baskets and our own modular pontoon system. This allowed works to be carried out efficiently with very little down time usually caused by the natural tidal cycle.
Kaymac carried out the excavation works behind the wall to enable the ground anchors to be installed. The anchor tendons, buttress plates and fixings were installed before pressure grouting works were undertaken to surround the anchor sections through the wharf wall and the ground anchor beam.
The works were completed within a very tight programme, through active and open collaboration with the client and various other contractors working within close proximity of each other on site.
