In the east of Moscow a new bus terminal is being developed on the Sholkovskoye Chaussee. Eleven stories of modern glass design. An attractive selection of shopping and entertainment facilities is elegantly combined with the bus terminal in an architectural complex. Approximately 1,600 bus services are expected daily and at peak times 1,000 passengers per hour.
After a construction period of only two years, the new complex is due to be completed in 2019.
The local contractor Fensma is not only confronted with a time constraint, but also difficult soil conditions: loam, sand, clay and groundwater. 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 in two respects.
Eight in one go
Deep foundation work for the new building is being carried out by a fleet of eight Liebherr machines including seven duty cycle crawler cranes and one piling and drilling rig type LRB.
The slurry wall has a maximum depth of 52 m and is 800 mm thick. Eighteen hours are required for the excavation of one bite with a length of 2,800 mm.
The HS 8100 HD is the newest machine in the fleet used by Fensma and convinces with a diesel consumption of only 23 l per hour.
Duty cycle crawler cranes at a glance
The duty cycle crawler cranes are robust and flexible in use and thus perfectly designed for dynamic deep foundation applications.
