Efficient, high-quality construction even with hand-operated formwork on special working areas

For a unique structural design, the conversion of a wastewater treatment plant required lightweight and quick-to-assemble racking and shuttering systems. The challenge was met - after proper preparation - with the help of MEVA AluFix wooden formwork and MT 60 heavy-duty scaffolding by the Kft. specialists of the contractor Ácsingózók.

They worked to precise plans

Of course, their success was due not only to the carefully chosen construction system, but also to the great professional experience of the client MM Épületgépészeti Kft., in particular the work of Endre Kenyó, technical director, and Ádám Máriássy, managing director, who managed the entire reconstruction. In addition, the engineers of MEVA - Kálmán Oberrecht and Szabolcs Gazgyik - provided technical advice, while Richárd Katus, a formwork technologist, supported the construction with 3D formwork plans edited with REVIT 3D software.

During the reconstruction of the "sedipac" type structure of the operating wastewater treatment plant, the working site could not be covered and the narrow space limited the formwork options, so the MEVA AluFix manual moving formwork and MT60 scaffolding were chosen. The scaffolding, which is approximately 6 metres high, both provided a safe working level for the demolition of the old reinforced concrete cross beams and provided load-bearing scaffolding for the rebuilding of the new block-lined concrete walls - beams (wall beams) with a "Z" cross-section.

Specific solutions were also needed

The working level was provided by the 1.70 x 1.70 m frame support of the MT60 scaffolding, erected on the axis of the block beam, and the MD400 slab supports fixed to it with andras bracing. The advantages of the MT60 scaffolding system, such as

• can be mounted without tools;
• the maximum weight of each element is 17 kg;
• integrated ladder and fall protection around the working level for safe working, and
• is compatible with all MEVA slab mill systems, supporting efficient operation.

In confined spaces and complex shapes, the MEVA AluFix formwork, optimised for manual handling, with its plastic formwork shell and articulated corner elements, has helped to produce concrete surfaces with a better than expected quality and a concrete appearance - and of course the required geometry.

To build the dimensionally accurate, fractional "Z" cross-section wall construction, MEVA's specialists also fabricated steel wall straps with a unique angle of rupture, allowing them to easily build the exact formwork with little adjustment work.
