A new high speed railway is being constructed in Korea to link Wonju and Gangneung as part of an extensive infrastructure programme for the 2018 Pyeongchang Winter Olympics. Gusan Construction has been contracted to work on Section 10 of the route, putting to great use its new DT1131i jumbo from Sandvik Construction. Used with RD525 drills and Alpha 330 rock tools, the rig has dramatically improved drilling times. Read the press release. Visit www.construction.sandvik.com. 15/15.
