As part of the R1 southern orbital motorway around the Czech capital, Prague, a joint venture is building a five-span, 461m long and approximately 65m high viaduct near the village of Lochkov, as a girder bridge construction. For the two steeply inclined twin piers, Doka has supplied an automatic climbing formwork solution that obviates the need for shoring and that will "cut more than 100 days from the construction period."

The Gold Coast region in the Australian state of Queensland is internationally renowned as a tourist area attracting thousands of visitors from Brisbane, where the state's biggest ever road and bridge upgrade project is currently underway.
