Eight in one go: Liebherr Entourage in Moscow
An urban construction project is currently being executed
in Moscow: an ultra-modern glass bus terminal with a
capacity of 15,000 passengers per day. This underlines the
importance of a good public transport infrastructure in
the Russian metropolis. Designed by the architect Werner
Sobek, the contractor Fensma is executing the project with
Liebherr equipment.
Deep foundation work for the new building is being car-ried
out by a fleet of eight Liebherr machines including seven
duty cycle crawler cranes with lifting capacities between 70
and 120 tons, and one piling and drilling rig type LRB 255.
Cast-in-place slurry walls with a total of 310,000 m2 and
3,500 tons of reinforcement cages are being installed as a
lining wall for the foundation pit. For this purpose, two car-rier
machines are fitted with hydraulic grabs and four with
mechanical grabs. These are applied as necessary and are
interchanged between the duty cycle crawler cranes.
The slurry wall has a maximum depth of 52 m and is
800 mm thick. Eighteen hours are required for the excava-tion
of one bite with a length of 2,800 mm. A delivery pipe is
used for filling the concrete. In addition to the slurry wall, the
deep foundation fleet from Liebherr is inserting 154 individ-ual
barrette piles for foundations. One barrette has a depth of
52 m and a volume of 110 m3 concrete. A total of 800 tons of
steel is being installed.
Quick and high quality: “And Liebherr is helping us”
After a construction period of only two years, the new com-plex
is due to be completed in 2019. The local contractor
Fensma is not only confronted with this time constraint, but
also difficult soil conditions: loam, sand, clay and ground-water.
Under these conditions it is a particular challenge
to achieve the necessary verticality of the slurry wall.
However, Fensma specializes in the realization of urban
building projects and is relying on the quality and service
of Liebherr construction machinery and customer service
during the execution.
“We build quickly and in high quality. And Liebherr is help-ing
us!” said Sergey S. Dyachkov, CEO of Fensma. Efficiency
and economy both play an important role. A diesel consump-tion
of only 23 L per hour for the HS 8100 HD, the newest
machine in the fleet used by Fensma, is a clear statement. The
cost for the modern glass complex amounts to €73 million
($123 million CAD). One fifth of these costs are attributed to
the deep foundation work.
GFL acquires Deep Foundations Group of Companies
GFLF Environmental Inc. (GFL) announced in February that
it had entered into a definitive agreement to acquire the
parent of Deep Foundations Contractors Inc. and its sub-sidiary
corporations (the Deep Group). Completion of the
transaction was subject to customary closing conditions,
including certain regulatory approvals and other consents.
GFL and the Deep Group were working together to obtain
the required approvals and consents and expected to close
the transaction in the second quarter of 2018.
For more than 45 years, the Deep Group has delivered suc-cessful
foundation piling and shoring work for its clients on
a wide range of projects in Alberta, Saskatchewan, Manitoba,
Ontario, Québec, New Brunswick and Newfoundland; includ-ing
the Children’s Hospital of Saskatchewan and the Bayview
and Avenue stations of the Eglinton Crosstown Light Rapid
Transit project in Toronto, Ont.
“Built on a culture of safety first, quality workmanship and
a committed employee and management team, the Deep
Seven duty cycle crawler cranes and one piling and drilling rig LRB 255: the contractor Fensma is relying on Liebherr during the execution of
the project.
