At good pace
C918 sections, the central part of Phase 2
of the Downtown Line which goes across
the city’s central district. Alpine has built 4
km of the tunnel, one fourth of the total (16
km) which also 3 subway stations.
A maximum safety project
The scope of the work carried out by AL-
PINE includes the construction of three un-
derground stations: King Albert Park Sta-
tion; Six Avenue Station in section C917;
and the Tan Kah Kee Station in section
C918. The three stations were designed to
meet the safety requirements of the project.
This is the reason why the length of the sta-
tion is longer than the average of any other
one because of the armour-plating, and the
platform of the Tan Kah Kee Station is 230
metres-long and 25 metres deep.
The technical complexity of the safety re-
quirements, applicable to all projects in the
island, was the great challenge that Dieter’s
team had to face on a day-to-day basis.
The project also entailed the difficulty of de-
touring traffic in the city’s midtown district
by means of temporary bridges spanning
up to 420 metres in length as well as the
affected services.
We asked Dieter Meyer to tell us about the
progress achieved in relation to the pro-
ject and he told us that it was going at a
spectacular pace despite the technical and
initial difficulties and that the work should
be completed by 2013 even though the line
will not be in operations until 2015 when all
the minor adjustments are completed.
