MT Supertube in first at Tate Modern extension T
ate Modern’s new extension, the £260m Switch House, required a highly creative approach to the installation of electrical
services in a concrete core rising through the centre of the 10-storey building, designed by renowned architects Herzog & de Meuron. Contractors, REL Building Services, ruled out costly galvanised conduit, opting instead for MT Supertube and in doing so breaking new ground in the application of the product. The cable management – carrying power, lighting, data, fire alarms,
security, access control and CCTV services – was encased within the building’s concrete core and delivered the architectural vision for flush- mounted electrical accessories without the use of voids for cable concealment in floors, walls or ceilings. Steve Jamieson, REL Technical Manager, said: “Only a flexible solution like
MT Supertube could have been used to deliver this installation as it allowed the team to bend lengths of conduit to fit into position around the steelwork and maximised the lengths we could use without a termination. “MT Supertube’s smooth inner surface also allows cables to be inserted using a traditional draw wire, enabling cable pulls of up to 50m in length through a tube with no fittings. This minimises the risk of cables snagging.” MT Supertube is a robust, lightweight three-layer tube-style conduit with the strength of steel but pliable by hand. The system was fabricated on deck at site and laced through the steel rebar network. Cable ties secured it to the rebar. Insulation tape was applied to each conduit connection over a 50mm width each side to ensure moisture resistance.
Marshall-Tufflex’s Supertube is at the heart of an iconic London development being hailed as Britain’s most important new cultural building for almost 20 years.
“We allowed an excess of around 2m on each length to protrude
beyond the concrete pour so that we could simply connect the next sections to the existing installation after each concrete pour had cured,” said Mr Jamieson. Jon Chamberlain, Marshall-Tufflex National Sales Manager, said: “This is a
stand-out application for our product and really showcases what can be achieved when interdisciplinary teams work closely together and think outside the box to solve specification dilemmas.” Medlock Electrical Distributors, of Waltham Cross, supplied the MT
Supertube.
