Renovation
Formwork and scaffolding solutions from Doka.
Renovation projects - from single houses to bridges.
Renovation projects are no longer just a niche activity; they're becoming a cornerstone of shaping our built environment. From energy-efficient upgrades in single-family houses to the modernization of commercial spaces and bridges, the redevelopment of existing structures is gaining crucial importance.
Renovation projects present unique challenges, such as the need to take careful account of existing conditions, minimize inconvenience to residents or neighbouring businesses during the works, and comply with conservation guidelines or building regulations. Doka provides a diverse range of formwork solutions tailored to meet the specific demands of renovation projects. Our offer, including engineering expertise, process optimization, formwork assembly, logistics, and rental options, makes Doka a valuable partner for the renovation endeavors.
Various areas of application
High-rise building
Dismantling or demolishing high-rise buildings in a city requires a nuanced approach. While blasting might seem like a swift solution, a controlled, step-by-step demolition offers several advantages. This method prioritizes safety for workers and additionally, it allows for material recovery and recycling, reduced debris and minimized risk of damage to neighbor builds and infrastructure. Doka climbing formwork systems are well-suited for controlled demolition projects involving concrete structures.
Dismantling the “Deutsche Welle”
![Deutsche Welle]()
Project information
Demolition of one of Cologne’s landmarks the 138m high towers of “Deutsche Welle” studio
Project requirements
- Careful dismantling process (demolition from top to bottom instead of blasting)
- Controlled demolition procedure step by step
- Area around the site and the teams had to be protected from noise, dust, falling debris and vibrations.
- High level of asbestos and concern of nearby residents
Doka solution
Both towers were fully enclosed with the Protection screens Xclimb 60 for dismantling. This ensured the safety of the team at every height and prevented debris, small parts, and dust from falling.
Renovation of Charite Berlin tower
![Charite Berlin tower]()
Project Requirements
- PH 1: Platforms for removal of old façade elements.

Voestbrücke: Danube River Crossing pylon refurbishment, Linz, Austria
![Voestbrücke Linz]()
Project information
In 2023, the section of the existing Voestbrücke bridge was renovated. This included maintenance work on the existing, approx. 65m high pylon.
Project requirements
Provision of a 65m high Ringlock modular scaffolding providing safe working environment, uninterrupted access and effective execution of work.
Doka solution
To achieve this, the pylon was enclosed with Doka modular scaffolding up to a height of over 60 meters. Integrated access ladders, enclosures and connection options for a material lift without direct tension anchoring to the pylon were necessary to ensure smooth work. The load transfer (at a maximum calculated wind load of 164 km/h) was realised via ring-shaped compression struts.
Conversion, extension, refurbishment and upgrading of existing buildings and structures
For simple renovation and refurbishment projects, formwork needs to be lightweight, easy to handle without cranes, strong, and adaptable. Additionally, renovating buildings brings unique challenges such as fitting tight spaces, working around existing structures, and keeping disruption to a minimum. Ergonomic considerations are also crucial for workers operating in tight and potentially awkward spaces.
The ultra-light Supporting construction frame AL 1
from Doka offers versatile support for single-sided walls. Compatible with DokaXlight formwork, it allows manual erection during renovation work and on craneless construction sites.
Doka Frami Xlife formwork systems precisely fulfil these parameters. The small, robust Frami Xlife panels remain manual formwork despite their steel frame. Can be put to use quickly, anywhere thanks to its many practical features.
Doka loading platform offers a temporary zone for crane-lifted loads on high-rises. Works with Doka formwork, scaffolding, and construction equipment. Pre-assembled in two sizes (3 & 5 tons) for direct installation on structures.
Doka's high-quality Xsafe Catch Fan quickly deals with the dangers of falling objects on construction sites, ensuring the safety of workers, bystanders, and pedestrians below. Its easy installation and rapid repositioning allow for comprehensive fall protection throughout the worksite.
Doka’s load-bearing towers Staxo 100 enable optimum adaptation to any project with a few components only. It combines high load capacity and safety in every situation. It provides high safety and speed on site thanks to built-in protective features such as integrated ladders and tying points.
