Ulma in the construction of the Waste Conversion Plant in Pavia
ULMA provided comprehensive engineering support, cost reduction, and high levels of quality and safety in the construction of the A2A Waste-to-Energy Plant project in Pavia, Italy.
The transformation of waste into energy forms the final phase of the
waste management cycle. This process, carried out in highly efficient plants
with innovative emissions treatment systems, provides significant environmental
advantages, including the conservation of resources and a reduced need for the
landfill of non-recyclable material.
Approximately 230,000 tonnes of material will be
processed at the plant annually, 99% of which will be incinerated to generate
200,000 megawatts of electricity, as compared to the 40,000 MW currently
produced.
The waste storage tank was the first structure to be
completed, a white concrete structure with a perimeter measuring 30 m x 50 m,
and walls 80 cm thick, reaching 40 m in height.
MK Shoring Towers were used to prop the 6 m thick transverse beam,
built at a height of 21 m, to support the hopper that feeds the plant’s large turbines. The
considerable thickness and weight of the beam required the use of heavy-duty MK
towers, whose size and flexibility of configuration make them extremely
efficient.
MK Shoring is one of
the best-performing heavy-duty shoring systems available for civil engineering
projects. It offers a load-bearing capacity of 250-360 kN per foot, with few
components and the capacity for multiple configurations. Assembly was
performed in situ quickly, safely,
and with continuous
oversight from an ULMA
technician throughout the entire process. The towers were set in place with
cranes, and after use could be moved and disassembled using, only the wheels
integrated into their bases.
For the various floors and
internal subdivisions onsite, aluminium ALUPROP towers were used to pour slabs
1 m thick at a height of 21 m.
The walls, which will reach a total height of 40 m,
along with the buttresses, were built with ORMA Panel Formwork set on BMK Climbing
Brackets anchored to the previously poured concrete.
The perimeter of the
work area was covered with BRIO Multidirectional Scaffolding and BRIO Stair Towers, providing complete and safe access for installing the steel
reinforcement.
In order to guarantee safety while pouring the slabs,
working platforms with MK walers were used to cover the gap to the floor below.
ULMA met the most demanding requirements of this type of project: reducing costs while providing solutions that are both high quality and safe.
