Titanic and Olympic were constructed on two slipways whose size and location are shown by illuminated blue lines. The site also shows the proportions of people who survived and died in the Titanic disaster, with decked areas for survivors and turfed areas for those who died, divided into areas for first class, second class, third class, and crew; with each drop in class, there were fewer survivors and more victims. Part of Titanic’s top deck plan is depicted in white granite lines. The original slipways, exposed here, were cast at a continuous gradient down toward the sea, and the ships’ prows were supported on two concrete wedges. Original bogey rails used to transport materials and tools during construction remain, as do features marking the foundations and footprint of the massive gantry stanchions, with adjacent steel columns representing part of the Arrol Gantry that encased the two ships during construction and originally reached 69 meters. Concrete piers at the end of the slipways contained machinery to pump out water behind the Cassons, which formed a temporary dam during construction of the ship hulls.
