The normal clutter of braced shoring is absent on a U.K. job to replace viaduct bearings near London because the shoring firm has created a cheaper and simpler megaprop system by bolting together standard stock. “We’ve never made these composite props before,” says Ian Fryer, engineering director for supplier RMD Kwikform Ltd., Walsall. “We hadn’t thought of it.”
Replacing the 108 bearings is part of a $9.2-million project to refurbish Country Way A316 viaduct. Prime contractor Carillion plc., Wolverhampton, started last May and is due to finish this spring.
