Statement in response to a media report on the tunnel boring works for the KCR Kowloon Southern Link
 
In response to a media report on the tunnel boring works for the KCR Kowloon Southern Link, Kowloon-Canton Railway Corporation issued the following statement today:
The tunnel boring machine (TBM) up-track tunnel drive commenced on 14 October 2006 and was suspended on 21 October 2006 due to a minor incident. The incident, which resulted in a subsidence of about 3 metres, caused no damage to the facilities, above or below ground, and was confined within the site boundary. Concerned government departments were informed of the incident and emergency measures implemented to stabilise the ground condition. Tunnel boring work resumed on 11 November 2006 after recommended mitigation measures had been accepted by the statutory authority and implemented.
A KCRC spokesperson said, "It is not uncommon to have teething problems during the initial stage of tunnel boring operation. More importantly 24 hour monitoring and contingency measures must be in place to deal with any incidents. In the unlikely event of a subsidence, mitigation measures can be implemented in two hours to resume normal traffic."
The concerned incident happened in the land-filled area where the soil is relatively soft. The TBM has now reached the rock layer under the Canton Road and has been working well.
