Lai King Building (LKB), established in 2001, a hospital facility dedicated to providing convalescent, rehabilitation and infirmary in-patient services and is part of the Princess Margaret Hospital (PMH) that is a major acute hospital in the Kowloon West Cluster (KWC) of Hospital Authority (HA).

With an ever-increasing elderly population, the demand for comprehensive medical care is expected in a growing trend, especially for convalescent and infirmary support. HA has decided to make use of the space next to the existing LKB, currently a rehabilitation garden, to develop a new hospital block as an LKB extension for more beds and treatment facilities for the patients in KWC. The expansion project will be implemented in three works stages, namely preparatory works, site formation and foundation works, and main works. The current project is the 2nd phase and scope comprises:

• Demolition of the existing structures at the rehabilitation garden, relocation of existing transformer room and VIE tank complex, together with tree felling, transplanting       and protection;

• Diversion, protection and re-arrangement of existing utilities serving nearby premises, in particular, the existing main drain from Highland Park that runs across the site;

• Large-scale excavation (~15m deep, ~volume 1200,000 m³) and lateral support (pipe pile wall) for a 3-level basement structure (approx. 15m deep) and the footings for        the new building;

• Construction of the foundation structure and earthing system for new extension block;

Tysan is grateful to have the opportunity to work for the Hospital Authority in this project which can in turn help to serve the public in KWC. The project poses several challenges to us as we are working in close vicinity to the existing LKB and several residential buildings nearby. Tysan is confident to overcome those difficulties and complete the project successfully.
