BOUYGUES CONSTRUCTION RECEIVES AN AWARD FOR "TUNNELLING PROJECT OF THE YEAR" IN HONG KONG
Dragages Hong Kong, a Bouygues Construction subsidiary, has
just won an award for the
"tunnelling project of the year", for a drainage
tunnel currently under construction.
This prestigious award was granted as part of the
International Tunnelling Awards organised each year by the
International Tunnelling Association and New Civil Engineer,
a trade journal, to reward a model project built under
adverse conditions. Their study's criteria are design,
execution, innovation, teamwork, commitment to local
residents and authorities, plus the ability to go beyond the
client's requirements and expectations. This drainage
tunnel to the west of Hong Kong won the prize in the category
of contracts ranging between USD 100 million and 1
billion.
Under construction jointly with Nishimatsu, a Japanese
company, the 10.5 kilometre tunnel is designed to solve
seasonal flooding problems by carrying storm water directly
to the sea. Two tunnelling machines were needed to cut
through the area's granite and volcanic terrain.
Designed to pierce hard rock, they are largest of their kind
ever used in Hong Kong.
In addition, the raise-boring technique(1) was
used to sink 32 shafts from 40 to 175 metres deep in a highly
urban environment, a first for Hong Kong.
Delivery of the tunnel, which mobilized 1,000 staff at its
peak, is scheduled for June 2012. Dragages Hong Kong is
currently boring several railway tunnels, working on
building
projects and a cruise-ship terminal.
(1) A technique used to dig very deep shafts through solid rock in record time.
