Cut and welded repurposed steel tubes saves 50% on construction costs
Canary Wharf’s new district, Wood Wharf, was been designed to provide a new residential led, mixed use, waterside community defined by the quality of its public spaces and the diversity of its land uses.
Our customer was tasked with creating a concrete foundation slab - which several of the main towers involved in the development would be built - that would sit on steel incased reinforced concrete tubular piles sitting above the water level of the Thames.
Over 2220m of tube was required which Cleveland Steel & Tubes had in stock. The pipe was reserved for the project and was cut and welded together using our in-house fabrication facility to the required lengths. A typical feature of this type of complex project is a 40mm thick specially rolled reinforced bayonet collar added to the top of each casing, enabling the unit to be twisted into the ground.
The customer asked if Cleveland Steel & Tubes could redesign the collar and our team recommended using a 500 mm long piece of 1219 mm O/Dia x 17.5 mm Wt. pipe cut and welded around the top of the casing. This engineered solution delivered a 50% cost saving over the traditional collar arrangement. CST ensured a steady flow of casings to the contractor therefore meeting their exacting delivery requirements.
