                   Mr  Piercy’s  “walking”  pile-driver  commenced  its  operations,  arousing  considerable

                   interest as it walked into the sea and adjusted its legs to the depth of the sea bed. It carried
                   its own lifting and driving machinery and Piercy patented it and it was subsequently used

                   in other parts of the world. (Fig. 3.11.)


                   The basic structural unit of the pier was a pile ie. a steel-reinforced concrete post 14 ins.
                   square, 45 – 52 ft long, and weighing 3 – 4 tons. Each one was fabricated on site in a yard

                   on the reclaimed land at the root of the Central Jetty, and there were 200 of them. (Figs.

                   3.12 - 3.15.) They were driven into the seabed down to bedrock by the electric pile-driver
                   mounted on the travelling stage, arranged in sets of 4, spaced 13 ft by 10 ft, and braced

                   horizontally. The spaces between sets was 18 ft crosswise and 27 ft lengthwise, so that

                   boats would be able to pass easily between them. The stage had to move 36 ft sideways to
                   put in each set and then 12 ft forward to plant the next set, and it planted at the rate of two

                   piles per day. The spacing was  closer at  the sea end, where  a considerable amount of
                   heavy superstructure was to be built. Once they had all been planted they were topped off

                   at the same level, cross beams were set in place, and an in situ concrete deck cast on top.
                   This was later covered with paving slabs. Deck construction was rapid and took place at

                   the rate of 200 ft / month.


                   Completion  of  the  Pier  had  been  expected  in  1912  but  industrial  unrest  in  England

                   delayed the delivery of materials and the project ran on into late 1913. It was formally
                   opened at 4 p.m. on Thursday 20 November 1913 by the Provincial Administrator, Sir

                   Frederick de Waal.

                                          CAPE TOWN’S NEW PIER OPENED

                                                 Ceremony this Afternoon

                          A crash of joyous music, loud cheers from the enthusiastic citizens, and the
                   unfurling of Union Jacks on tower and turrets marked the occasion of Cape Town
                   entering into possession of her new pier this afternoon. The stately structure which
                   stretches 1,000 feet into the Bay, and which is expected to play such a prominent part in
                   the future of the City as a seaside resort – attracting visitors and providing for their
                   recreation and amusement – had assumed gala garb in honour of the event. An avenue of
                   gaily-coloured Venetian masts, from which suspended a mass of bunting and fairy lamps,
