Germany – Structural steelworks – Modernisierung GS Dorschbergschule - Stahlbauarbeiten

The Dorschberg Primary School in Wörth a. Rh. was constructed in 1966 and is located behind the central building of the Carl-Benz Comprehensive School in Wörth am Rhein. The primary school consists of four building sections, including a single- or two-story building section with connecting corridors, a break hall with an administrative wing, and a single-story pavilion building with four pavilion buildings. The buildings are connected by break corridors and have two toilet buildings. The single- to two-story buildings were constructed using solid concrete prefabricated parts and have flat roofs at different height levels with a surrounding attic. They have been renovated and modernized several times to date. In the mid-1990s, concrete renovation took place. As part of this, a thermal insulation composite system and the Alucobond cladding of the attics and prefabricated supports were installed. Key construction measures - The existing single-story classroom wing will be extended, and the previous courtyard area between the two existing classroom wings will be enclosed and roofed. For this purpose, the insufficiently load-bearing prestressed concrete ceiling above the northern classroom wing will be dismantled and replaced by a new solid reinforced concrete ceiling. - The new upper floor will be constructed using prefabricated timber construction with load-bearing walls as solid timber construction or timber frame construction and the top floor ceiling as cross-laminated timber construction. - The central auditorium will be fitted with a glass roof construction. - The prestressed concrete ceiling in the corridor area above the existing crawl space of the north wing must be reinforced by steel beams. - Minor layout changes in the existing structure - The pavilions will be gutted and converted into an extended covered courtyard area - Improvement of the thermal insulation of all building envelope surfaces (roof surfaces, windows, rear-ventilated timber facades, cellar ceiling insulation) - Modernisation of the technical building equipment including controlled ventilation system with heat recovery, energy-saving lighting systems, building automation, including the digital requirements for school buildings - Optimisation of fire protection and implementation of the school protection concept.
