International Projects in Scaffolding Trade

Preserving this important cultural monument requires continuous refurbishment operations. To renovate the gatehouse, the oldest building part of the castle, the PERI UP Scaffolding Kit could be flexibly adapted to the difficult geometry. In spite of countless mounting parts, projections and recesses, as well as scaffolding a circular tower, system components were used to the greatest possible extent. This resulted in accelerated assembly operations and simultaneously enhanced safety levels when using the scaffolding. For the winter roofing, PERI designed a project-specific scaffolding solution with heatable Keder sheeting. Heating wires integrated into the tarpaulins ensured that snow accumulation and, thus, any unintended loads were avoided during the colder months.

Three solutions were required for construction of the flats: one scaffolding system for attaching the facade elements and windows, another for the balcony around the building and a third for the cantilevered part that gives the building its special shape. The PERI UP Scaffold System was the answer to all three requirements. On the one hand, it is ideal for the construction of robust facade scaffolding and falsework that have to withstand high loads; on the other hand, the metric grid makes it easy to assemble and connect other PERI system components.

A new residential complex consisting of five buildings, each with six to eight storeys, was built on the site of the former Ministry of Foreign Affairs of Israel. PERI supported the project in the heart of the New City of Jerusalem by providing around 25,000 m² of facade scaffold, which facilitated the process of mounting the stone cladding on the building facade. PERI provided support with scaffolding planning from the very beginning of the project. The complex geometry of the buildings meant that the PERI UP system had to be extremely adaptable. This is because certain changes had to be made to the assembly even during the cladding stage. In addition, PERI ensured that the  materials were available on the construction site, thus enabling a smooth workflow.

Complex structural geometry, significant spatial restrictions and poorly accessible sloped areas – the 167 year old, 180 m long and 40 m high viaduct on the railway line between Riesa and Chemnitz posed unique challenges to the parties involved. The company Gloser GmbH opted for PERI scaffolding solutions in order to carry out the extensive repair work on the masonry of the arches and the bridge piers made of natural stone and bricks, and, at the same time, to restore the track supporting structure and the drainage facilities.

The Deepspot diving facility, which reaches depths of up to 45.50 metres is divided into two sections: the main section reaches a depth of 15.50 metres, while the diving tube is 25.45 metres deep. The tube depth is roughly equivalent to the height of a 15-storey building and holds a total of 8,000 m³ of water. Deepspot opened at the end of 2020 after a construction period of only around two years. As early as the planning phase, the responsible PERI engineers paid attention not only to the static feasibility but also to the safety of the site personnel. The used and pre-assembled PERI systems, as well as the selected concreting procedure, ensured that work was carried out safely at all times – even in the great depths of the diving tube.

Gurrehus, which was built in the 16th century, is located in the north of Denmark. In the past, the building was used as stables for Gurre Castle, which has since fallen into disrepair. To save the Gurrehus from a similar fate, extensive renovation work was carried out using various PERI UP scaffolding solutions. Thanks to the LGS 75 Weather Protection Roof, the team was able to carry this out quickly, without being affected by the often changeable Danish weather. To this end, a roof was erected over the entire building, which has a unique design.

The “Ypsilon” residential and office building, a building complex complete with a 35 m high tower with a trapezoidal-shaped floor plan and adjacent 7-storey lateral tract, is the new striking western gateway to Ulm´s city centre. Behind its rounded building corners and a glass and aluminum facade are retail outlets, offices and apartments. For the shell construction and finishing work, a working and safety scaffold based on the PERI UP Scaffolding Kit was created. Due to the consistent metric grid dimensions of the system, the demanding building geometry could accurately be followed.
