He explained:
"Instead of having to send a survey team to measure
and mark the surface of the rock, two workers can do the job within a matter
of minutes."
The construction of the tunnels is being carried out by a consortium
comprising Gammon (Hong Kong) Ltd; Sentab Svenska Entreprenad AB of
Sweden; Hochtief Aktiengesllschaft of Germany; and Societe Francaise
d'Entreprises de Dragages of France.
It involves the building of three main tunnels, a number of branch
tunnels and their associated stream intakes and shafts.
One of the main tunnels will cut across the entire Sai Kung peninsula
linking High Island Reservoir at the south-eastern end of the peninsula with
the Sha Tin Treatment Works and further with the Lower Shing Mun Reservoir at
the western end.
The other two main tunnels which are shorter, will be built north of
High Island Reservoir, and will stretch northwards from Pak Tam Au to Hoi Ha
and from Wong Chuk Hang to Sai Wan respectively.
The tunnel, which stretches across the Sai Kung peninsula, is divided
into two sections. The section west of Tai Wan and its branch tunnels, totalling
about 14 miles in length, are being built by the Public Works Department, while
the other section east of Tai Wan as well as the two other shorter main tunnels,
with a total length of 11 miles, are being constructed by the consortium.
The cost of these tunnels, which range from six feet to 13 feet in
diameter, is equivalent to one quarter of the total cost of the High Island
Water Schome.
