Wood Wharf

Expanded Geotechnical constructed the bearing piles for three residential towers and the marine piling for a precast deck to form part of the public realm.

Scope. Construction of the first phase of the bearing piles under towers A1, A2 and A3 comprising 1.5m diameter rotary bored under bentonite in addition to 900mm diameter CFA piles up to 28m deep. We also cored the existing dock wall, undertook attendances to the piling rigs, including construction of piling mats, and the erection of temporary steelwork supported on plunge columns to brace the combi wall.

Land-based works. These works were undertaken within a basement cofferdam on an accelerated delivery programme with up to three rigs working concurrently.

Marine piling. We also provided the foundation piles and precast deck for the proposed public realm areas of the Wood Wharf development; all of which were constructed within the existing South Dock. These technically demanding piling works involved construction of large diameter piles up to 30m deep within permanent casings. The piles are bored under polymer support fluid from barges with site deliveries utilising barge transportation to minimise vehicle movements. Following pile construction, the precast beams and deck manufactured at our in-house precast specialists Explore Manufacturing and Bison’s facilities in the Midlands were installed which then served as a construction access route for the construction of the A1 tower.

Benefits of the Expanded approach. On both packages, Expanded offered an accelerated delivery programme through revised construction techniques, improved sequence and a coordinated logistics and delivery strategy.
