SITE REPORT
27
cranes in the yards that serve as warehouses
and workshops at the jobsite.
The five largest tower cranes,
including two 21LC750 with up to
48 tonnes capacity, and three 21LC550s
with a load capacity of 18 tonnes each,
are working on the second dam.
Another 5 tonne capacity 5LC5010
is working as a service crane, helping to
manage the machinery and materials
required on site, the company said.
Bridge towers
In addition to these tower cranes, two
Linden Comansa 21LC290s, with capacities
of up to 18 tonnes, are working on the
construction of a new bridge. The bridge
is 268 m long and 40 m high and once
completed will allow the EN102 road to
cross the river.
Around 1.1 million cubic metres of
concrete will be used and around 3 million
cubic metres of the site will be excavated.
The dams are being constructed by Baixo
Sabor ACE, a joint-venture company
formed by Odebrecht and Bento Pedroso
Construções, and Lena Construções.
The budget for the project is
estimated at more than € 480 million
(US$ 643 million). Together the two dams
will flood an area of more than 50 km.
On completion the hydroelectric power
plant, which has been under construction
since 2008, will have an installed capacity
of 170 MW and will be capable of
generating up to 444 GWh per year. The
power project is due for completion in
August 2014.
