Adaptable scaffolding system accelerates bridge refurbishment



The 70-year old reinforced concrete arched bridge which crosses the Rio Tua in Northern Portugal had to undergo extensive refurbishment. It has a total length of 120 metres and is 8 metres wide. The concrete arch has an 80 m span and the superstructure is supported on a number of piers along the two side extension sections. With PERI UP Rosett Flex, safe access was provided to all structural components and loadbearing working platforms for renovation work to be carried out.

The contact area for the up to 20 m high scaffold construction was 7 m wide, at the highest point, the scaffold is 11.75 metres wide The lateral cantilevers along with the bridging between the outer bridge piers were realized with PERI UP system diagonals without the need of any additional auxiliary components. For this, the standards were connected with the node braces which had already been attached, and simply swivelled outwards via the ledgers with the scaffolders always in a safe and secure position.

Through the optimal adjustment of the modular scaffold system to the complicated bridge geometry, scaffold assembly as well as the renovation work could be accelerated. The improved accessibility along with increased working safety levels meant that construction time fell below the originally scheduled seven months. The fact that the scaffold bays were completely covered with system decking resulted in no dangerous gaps which greatly contributed to increasing safety levels during use for site personnel.

    “In addition to fast assembly, PERI UP provides a high load-bearing capacity. As a result, we could also work on the platforms with heavy materials, a crane was not required. Apart from this, the scaffold system was so fl exible that any unexpected adjustment work due to inaccurate building plans did not adversely affect the scaffold solution nor construction schedule.”
