Reach And Accuracy Demanded - continued
In addition to the construction’s unique architecture, where none of the walls are straight and the inclination of the roof varies from 14° to 20°, working from the outside meant that we were also challenged by the weather that can be very tough and windy in Denmark particularly during the winter,
As a consequence of delays caused by holdups in the building’s construction, two-thirds through the job we found that we were left with just eight months to complete the facade according to schedule.
Machines tailored to the task
To adapt to the challenges, Sipral relied on a unique combination of six Scanclimber mast climbers and two bespoke monorail hoist systems used in conjunction with the three Genie booms.
The facade had to be installed from the outside due to complex pipework and steel frames making access from the the inside very difficult.
Machines tailored to the task
Operated from ground level and from the roof, the machines worked together to lift, lower and secure the initial base layer of the façade’s 1.5 tonne sections of thermal, acoustic and waterproof cladding into position. This was followed by the second and final phase of the process: Positioning and installing the decorative outer layer comprised of 3, 250 aluminium brick-style cassettes each weighing 80 kg.
Other equipment on site included several Liebherr crawler cranes provided by BMS including a 750 tons LR 1750, a 600 tons LR 1600, a 350 tons LR1300sx a 375 tons CC2500 crane, two 200 tons LR1200, and a 160 tons LR1160 (all from BMS crawler cranes).
To progress rapidly, Sipral knew its workers would need to rely on an efficient and reliable mobile access solution to help them complete the job in time.
Amager Bakke is an extremely complex and large construction,
Genie booms played a key role in providing our team easy high-precision access and smooth positioning on all sides and angles of the facade, as well as offering the stability that their safety relies on.
Having been operated on the site for the past year,
All three Genie units proved to be extremely reliable and, despite the job’s complexity met our requirements perfectly both in terms of their smooth capabilities, mobility and safety,
For Sipral, that also specializes in state-of-the-art access systems, the next step of the job will be the construction of the plant’s entry ramp during summer 2017.
Sipral is supplying the Amager Bakke project with complex external cladding and a special interior glass partition to separate the administrative and operational sections.
Samples of these two different façades successfully passed rigorous tests for air permeability, waterproofness under static and dynamic pressure (created by an aircraft propeller), resistance to wind load, as well as impact tests.
The façade met all the requirements, and the first modules were installed in Copenhagen this July, 2016.
Once fully installed, the façade envelope will be covered by a second, aesthetic layer of natural aluminium panels (almost 3,250 units). The façade envelope includes an ‘attic’ element that will also serve as a railing to shelter from the wind visitors moving around on the publicly accessible rooftop.
