Hong Kong’s Strategic Sewage Disposal Scheme (SSDS) Stage I involves the provision of a system of deep tunnels for transporting to a central treatment works wastewater collected from a number of catchments around Victoria Harbour. For the SSDS Stage I works, about 24 km of tunnels have been excavated in hard rock at depths ranging from about 80 to 150 m below Victoria Harbour and the surrounding heavily developed areas of Kowloon and Hong Kong. Five tunnel boring machines(TBMs) with diameters ranging from 3.2 m to 4.3 m were used to excavate the tunnels. Tunnel excavation has been completed and tunnel linings are in progress. Major tunnelling issues such as ground stabilisation and water control encountered in the project are summarised. An overview of one of the possible future tunnel systems that might be adopted in subsequent stages of SSDS is also presented.

Hong Kong is an intensively developed region and has the highest vehicle densities in the world. In 2000 there were 6.6 million people and 580,000 vehicles using 1,890 km of road covering the 1084 km 2 territory. The high vehicle and population densities together with the difficult terrain have seen road tunnels emerge as key components both in the current and future road transportation network. Currently there are eleven operating highway tunnels in Hong Kong, seven government owned and the remaining four “build, operate and transfer” franchises, see Figure 1. The very first tunnel was the dual two Lions Rock Tunnel completed in 1967and the latest the dual 3 lane Tai Lam Tunnel opened in mid 1998. Figure 2 shows the alignment and statistics for all 11 Hong Kong tunnels. Looking ahead, Hong Kong has embarked on the study and design of the next generation of major highways and as many as a further seven tunnels are currently under feasibility study or detailed design. This seems an opportune year to produce a broad appreciation of the fire strategy, life safety and ventilation practices in Hong Kong not only for the existing tunnels but the new standards and requirements for the next generation of Hong Kong tunnels. This paper provides an overview of the fire strategy, life safety and ventilation of Hong Kong’s existing and planned tunnels. The paper pays particular attention to the areas where the unique conditions and requirements in Hong Kong impacts on tunnel and systems design and the solutions adopted to overcome these challenges.

The Honor Roll includes the names of all members of the Institute whom we know to be on active military duty at the date of its compilation, February 7, 1918. We are aware that there are many others of whose activities we have not been informed, and we shall be grateful for information as to any such omissions from the Roll. 1. MEMBERS ON ACTIVE MILITARY SERVICE Mail addressed to members on the first division of the Roll and sent to the office of the Institute Will be forwarded according to the best of our knowledge at the time.

The Honor Roll includes the names of all members of the Institute Whom we know to have been on active military duty it the date of compilation, Mar. 5, 1919. Despite our efforts to have this list accurate and complete, some of our members who have been rendering military service are probably left off because of the fact that we have not been informed of their military connection. The list of men in military service has been compiled with great difficulty owing to the modesty of the members, who in their patriotism began their service but neglected to send us notice. In 1918, We published a separate Honor Roll of the Institute in which we included a list entitled "On active duty in other departments of the service" which contained the names of members who were rendering important emergency service to the Government other than in the Army. This list is entirely omitted this year because any list We might compile for this purpose would be entirely inadequate and must inevitably do injustice to a large number of our members who have been devoting great time and making many sacrifices for the benefit of the government along lines not within our ken. It is not too much to say that almost all our membership in this country has been, more or less directly, doing its uttermost for the successful prosecu¬tion of the war. The active work of many of these members we are Well aware of, as is also the rest of the civilized world. Faithful and wholehearted efforts on the part of many other members we have not been informed of, so that any list would be both incomplete and unsatisfactory.
