The WD-102 Viaduct is a newly constructed bridge with a total length of 275 m (902 ft) and a width of more than 27 m (89 ft). The project was executed using the incremental launching method, making it particularly suitable for a long structure with a constant cross-section.
BrandSafway supported the construction with a system-based formwork solution, enabling controlled, repetitive concreting operations and a highly efficient construction process.
The main challenge of the WD-102 Viaduct project was the construction of a long bridge superstructure using a method that required precise geometry, consistent quality and reliable repetition for each segment. The formwork solution had to support large concrete sections while allowing the completed segments to be pushed forward safely and accurately.
In addition, the construction process demanded a stable casting bed and a formwork concept that could accommodate external, internal and bottom formwork elements, while ensuring efficient assembly, stripping and repositioning throughout the sequence.
The solution was based on the INFRA-KIT modular formwork system, providing a flexible and robust technical design tailored to the incremental launching method. The formwork configuration consisted of external formwork panels, internal mobile formwork and bottom formwork panels, allowing precise shaping and reliable support of the viaduct superstructure.
The WD-102 superstructure was concreted in long segments on a stationary casting bed, each measuring approximately 24 × 15.5 m (79 × 51 ft). In total, 26 concrete segments were produced and subsequently pushed forward over the piers using hydraulic cylinders and cables. This approach ensured a smooth, repeatable construction cycle and demonstrated the efficiency of the incremental launching method for long bridges with a constant cross-section.
