Cityplaza – Phases III & IV

Completed Project

Height restriction prompts space-saving innovations

Positioned at the periphery of the flight path of Kai Tak Airport, a major construction consideration for the project was to maximise floor space within the height restrictions enforced by the government.

Extra strength post-tensioned floor slabs were used, allowing for a full 2,300 square metre floor span without the need for supporting beams. On the lower floors, high-strength concrete was used which allowed for narrower load-bearing columns.

These space-saving features increased usable floor space, and allowed for an additional floor, per building, to be added.

To meet the tight deadlines, Dragages used steel table form to build the office towers, the same method adopted during the Pacific Place development. Together with the adoption of early-strength concrete, the two office towers were completed within 23 months in a four-day-per-floor cycle.
