ERS Track For
New Bridge In
Track installation on a new bridge in
the Finnish capital took place in mid-Ju-
ly 2015 and is the first project for HKL
(Helsinki City Transport) in which ERS
(Embedded Rail System) was used. ERS
is primarily used for maximum stray cur-
rent protection and low building height.
It was applied by
cessfully installed 208 meters of ERS-
track on the new Pasila bridge.
The ERS installation was done as a
turnkey-job in close cooperation with HKL.
The new bridge is built right next to the existing Pasila
bridge. The two bridges, which will be connected, create
a new double tram track in the middle to provide more
space either side for the (separated) road traffic.
HKL chose for ERS, because it is virtually a maintenance
free system, and thus providing maximum availability of
the track and saving in maintenance.
HKL has planned the renewal of the old part of the
bridge in 2016. And also for the new track on this part of
the bridge ERS is their
Piling For A Large Power Station
The Dominican Republic frequently experiences massive
blackouts. Often the entire island nation, which has an area
of approximately 49,000 square kilometres, is affected.
A new coal-fired power station, currently being built
about 40 km from the capital city of Santo Domingo, should
solve the country’s power problems.
In September 2014, the consortium Odebrecht-
Dominicana S.R.L. – a subsidiary of German BAUER
Spezialtiefbau GmbH – the contract to construct the foun-
dations for this power station.
The work executed by Bauer include soil
compaction with around 210,000 m of con-
crete columns, 50,000 m of polymer-sup-
ported bored piles with diameters of up to
one meter and construction of 6,500 m²
of diaphragm wall, 1.2 m wide and up to a
depth of 30 meters.
Two Bauer BG 28 large-diameter rotary
drilling rigs and three vibration units are in
use, in addition to auxiliary cranes and small
The coal-fired power station, with a ca-
pacity of 750 megawatts, is scheduled to be
connected to the power network in 2017.
