Port of Tyne Drainage Alterations


Contract length


The Port of Tyne made significant investments in the 20 acre site with this project being part of that investment. An existing 2700mm diameter manhole and concrete pipes were failing due to age and were exposed and broken out to enable the laying of new pipeline and new manholes installed at various depths. The location of the new pipeline required the relocation of 300m of ductwork for electrics and the 6m by 2m penstock valve, including service ducts for power. The new headwall was formed using gabion baskets and the outfall and pipeline required breaking through the Quay wall which was up to 2.5m thick. We were asked to design an outfall that would not disturb the ties in the Quay wall. Different options were discussed and we proposed the used of gabion baskets. Works were completed around the tides including night working, requiring careful and forward planning and monitoring of the weather and working conditions to ensure programme was achieved.
