LARGESTRUCTURES
Scaling new heights
which has posed a number of challenges
– not least working in the extreme heat
of the country.
The company has supplied its
Mecanoconcept formwork for the first
time in the country, having successfully
used itwithinSpain for the past 40 years.
According to its developers, the system’s
use has boostedproductivity.Mechanical
Mecanoconcept formwork is said by the
company to be simple to work with.
It allows recovery of up to 80% of the
formwork equipment used within three
days of concreting, so that it can be
reused for shuttering higher slabs.
Hydroelectric scheme
Hydroelectric power schemes are proving
a growing phenomenon around the
world and the 1,285 MW Xayaburi
dam and power plant in northern
Laos is among the most notable.
A total of 19 Potain tower cranes
have been employed on the site,
operating 24/7 on the eight-year
project, which will create an 820 m
long dam across the Mekong River.
Their primary task is to place roller
compacted concrete at a rate of 250 m
3
per hour. Handling much of this work are two Potain MD
1600s.

consortium behind the US$ 2.3 billion
project signed an initial financing deal
for the scheme last autumn, with a total
of seven banks providing the capital.
The 59 m wide bridge will carry eight
traffic lanes and two railway tracks over
a central span of 1,408m and will form
part of the new 260 kmNorthMarmara
Motorway.
Formwork is being supplied by Peri,
which says the ambitious project will
include the tallest concrete bridge pier in the world. The
suspension bridgewill feature twoA-shaped pylons around 330
m inheight.Themain formwork for thiswill be Peri’s ACS self-
climbing system andVarioGT 24 girder wall formwork.
For the inclined surfaces of the A-shaped pylon legs, the
adjustable version of the ACS V self-climbing formwork is
being used, which can be adapted to suit the sloping sides of
the pylons.TheACS climbingunits also include sheet cladding,
which offers fall protection as well as additional wind and
weather protection for workers.
Udinese
Tackling major renovations to football stadium inUdine, Italy
has proved a rewarding task for formworkmaker Pilosio. It has
been involved in the upgrade of the Stadio Friulimulti-purpose
stadium that includes gymnastics, athletics, and martial arts
facilities and is also home to theUdineseCalcio football team.
The project involves remodelling the present seating
arrangement of 41,652 capacity, which has required a complete
rebuild of its north and south stands. Its west stand, whichwas
already covered, will be refurbished as part of the works that
have included Pilosio providing P300 formwork for casting
foundations and walls, plus a modular system for scaffolding
and service stairs.
Meanwhile,Alsinahas demonstrated its flexibility in takingon
aparticularlyunusual large-scale construction task. It is involved
in building an internal security forces camp in Doha, Qatar,
Pilosio has supplied formwork for
a major upgrade for the Stadio Friuli
stadium in Italy.
Formwork fromAlsina is a key part of
the operation to create a newmilitary
camp in Doha, Qatar.
The Xayaburi dam in Laos is an eight-year project that
has seen 19 Potain cranes in action.
