Public bus station in Szprotawa with a roof structure made of glued laminated timber

For the new public bus station in Szprotawa, HASSLACHER group supplied glued laminated timber components produced at the Magdeburg site (NORDLAM GmbH) for a complex roof structure made of glued laminated timber, executed by the Polish company “BSHaus”. The project combines modern architecture with sustainable building materials and precisely engineered timber solutions.

Load-bearing glued laminated timber beams – technical specifications and engineering performance
The roof structure consists of glued laminated timber beams with a width of 240 mm and a height of 640 mm, as well as secondary beams measuring 120/640 mm, complemented by parapet beams. All components were manufactured from glued laminated timber in strength classes GL30c and GL24c in accordance with EN 14080, CNC-machined and prefabricated with high dimensional accuracy and precision.

The engineered timber structure comprises a total of 16 nodes and required more than 85 m³ of glued laminated timber as well as a large number of structurally relevant connectors.

Prefabricated timber construction and fast installation
Thanks to the high degree of prefabrication and CNC-based processing, the installation of the roof structure was completed in less than three weeks. This highlights the efficiency of modern timber construction systems and advanced factory prefabrication, even in the field of infrastructure projects.

Architecture and functional design of the bus station
Designed by Agata Pawlak, the new bus station features modern architecture, generous glass surfaces and durable materials. Inside, passengers have access to a waiting area, barrier-free sanitary facilities and ancillary rooms, creating a functional and welcoming public infrastructure.

Timber-based infrastructure for e-mobility
The facility is designed for the operation of eight electric buses and is equipped with four double charging stations, each with a capacity of 120 kW, as well as an integrated energy storage system. In addition, a photovoltaic system is planned on the roof structure, further strengthening the project’s role as a sustainable, timber-based infrastructure solution for green mobility.

As highlighted by local authorities, this modern bus station supports free and environmentally friendly public transport throughout the municipality and sustainably connects the population with workplaces, educational facilities, healthcare services and shopping opportunities.
