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.” Photo: RMD Kwikform Ltd.

The global construction market had been booming in 2007 and through midyear 2008, and large international contractors and design firms reaped the benefits. The demand for big-ticket projects, from petroleum production facilities and powerplants to major infrastructure upgrades and signature buildings, made the demand intense for world-class contractors with the size and expertise to deliver these projects. As a result, big firms around the world were scrambling to grow, either organically or through acquisition, to meet this demand.

Thousands of workers daily take the train from their homes at Slavutich, across 55 kilometers of unpopulated woodland and marsh in northern Ukraine to their workplace. No ordinary commuters, they are workers at the Chernobyl powerplant, scene of the world�s worst-ever nuclear disaster.

Among the construction teams is Alexander Nikolayevich Plotnikov, project manager at contractor Utem Engineering, Bucha.
