Placing a metal plate on the beams resting on blocks so the bottom plate can be set in place.
The first metal plate allows the workers to walk safely across the work area to get precise dimensions.
Acts as a guide to line the rest of the plates on.
View from gantry crane that runs on rails next to work site.
Workers are attaching cables and spanner to lift the second plate on to the beams.
The keel acts as walk way has so workers can accurately place/line-up the large prefabricated plates of the hull.
Assembly area shown on left.
The second plate for the hull of the Fitzgerald (see 1D) that shows the workers attaching the cables lifting spanner on which the gantry crane will use to lift the plate.
Second plate in hull 301 beams set on blocks are leveled with wedges.
