– the open space is 11 times bigger than the Melbourne Cricket Ground ( MCG ) thanks to building six kilometres of new elevated bridges .
But the stakes were high . “ It is the busiest rail corridor in Melbourne ,” explains Summers , “ so it has the most amount of people moving backwards and forwards , and we had to keep them moving pretty much the whole time getting them from point A to B , while we built this job in and around a live train environment .”
The biggest challenge was that it ’ s a very tight rail corridor – less than 20 metres in some areas such as between Caulfield and Hughesdale . Many of the locations had residential properties that backed right up against the corridor – of the 113 houses that were eligible for purchase by the government under a Voluntary Purchase Scheme , 74 have settled to date , meaning the construction was very often right next to people ’ s homes and back fences . As a result , they pulled in the big guns by deploying a blue straddle carrier , which allowed the 2000- strong workforce to build above the existing train line , while the trains continued to run underneath .
