AFTER towering above Central for more than four years, the 52 metre-high ''chop stick'' spires of the Bank of China building are due for their first full repaint. A representative from the building's management agent, Hutchison Estate Agents, said contractors from Australian high-rise maintenance company EW Cox would spend about a week perched at the top of the building. The bank spires reach 367 metres, but are still five metres shorter than Central Plaza. One young member of the painting team was hauled by his three colleagues to the top of one of the spires, where he pulled an Instamatic from his work pouch and snapped a few shots of trouble spots on his and the opposite pole. From a vantage point in a much safer location nearby, South China Morning Post photographer DAVID WONG caught the action.
