Land & Water were commissioned to carry out the construction of 3 new dry docks.

The works consisted of the installation of 200m of LX27 sheet piles of various lengths, from 4m up to 12m and 9 tubular fender piles 18m long with a diameter of 610mm with another 24 tubular piles for a new crane platform. These piles were installed using movax piling rig.

The crane platform was constructed using a temporary support system of stub beams welded onto tubular piles, these had adjustable jacks & Megashor waling beams attached to carry the temporary support system. This system carried the full crane slab whilst under construction which was approx. 30m x 10m wide with the thickness of 550mm. This was poured in single operation with 185m³ of concrete placed in one day.

In addition to the piling works a new workshop and welfare facility was constructed using a steel portal framed building and associated drainage works.

The existing piled revetment works were failing and support was required for the riverbanks, both up and down stream of the lock and weir.

Due to restricted access, the works had to be carried out using floating equipment. Downstream and adjacent to the weir, new 7m long sheet piles were driven in front of existing piles using Land & Waters Movax pile driving attachment.

Granular dredgings from the river were then extracted and used to backfill behind the new pile line. Along the edge of the by-pass channel, galvanised steel sheet piles were driven at the bank edge and tied back to anchor piles. These again were back filled between the structures using granular material recovered from the river. Further revetments were required to shore up banks.

This was completed by using 4mm galvanised weld mesh panels behind timber posts filled behind with gabion stone. Finally, a timber oak coping and rubbing strip was attached giving both fender protection and pleasing aesthetics.

All works were carried out safely within a busy public area with all parties being pleased with the result.
