On the day of RAIL 's site visit, in heavy weather, the scaffolding and decking that engineers stand on were submerged deep under choppy water, with work suspended. "We have to work around the tides," explained Project Director Alan Venables. "The wind pushes the tide up and the waves get larger. That causes some problems with the scaffold."
