Kowloon, mainly for ships in the coastal trade, was opened in 1868 to be followed soon afterwards by a shorter 80m-long dock. A few years later (1876) the 140m-long Cosmopolitan Dock and dockyard at Tai Kok Tsui were commissioned. Subsequently the much larger 168m-long Admiralty Dock at Hung Hom was completed in 1888 and later extended in length by some 8 metres in 1903, to be followed by further lengthenings in 1911 and 1931.
In the summer of 1907, the 170m-long Admiralty dry dock in Victoria, with an entrance width of 29 metres and 9m clearance at lowest spring tides, and Tai Koo's great ashlar-faced 238m-long 27m entrance-width graving dock (now a car park in the Tai Koo Shing development) at Quarry Bay, the latter capable of accommodating the largest ship then afloat (the liner Oceanic), were both commissioned. By laying down the former dock where it did and extending the original dockyard, with an 8ha reclamation which was started in 1900, the Navy sealed the long-held hopes of making Victoria a coherent city with a continuous commercial waterfront. Due to difficult foundation problems, including removal of a 1.2 to 1.8m layer of hard porous coral and the need to install hundreds of steam-driven hardwood piles through the underlying decomposed granite to secure the site, the naval dry dock finally took seven years to build whereas the larger commercial dock at Tai Koo was finished in five.
The whole of the Tai Koo dockyard development took seven years to completion in 1908, a remarkable achievement in so much that it not only included the large dock but also excavation of some 1.3M cubic metres of hillside to form a 21ha site, which included a 8ha marine reclamation, and the adjacent section of the 23m-wide cut for King's Road, and the building of an entire complex of slipways, workshops and all the ancillary works which are needed to make a large dockyard a world of its own. It is interesting to note that Admiralty engineers in 1908 regarded locally-made cement as unsurpassed in fineness and tensile strength (at 28-days around 750lb/sq in or 5.2MPa), and it was used exclusively when building the new naval and Tai Koo dockyards.

By 1843 there were several comparatively small piers and jetties on the Island located between East Point and Sheung Wan. Pedder's
