Germany – Structural shell work – Modernisierung GS Dorschbergschule - Rohbauarbeiten

The Dorschberg Primary School in Wörth a. Rh. was constructed in 1966 and is located behind the main 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 heights with a surrounding attic and 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 the prefabricated supports were installed. Key construction measures - The existing single-story classroom wing will be extended and the former 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 in 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 provided with a glass roof construction. - The prestressed concrete ceiling in the corridor area above the existing crawl space of the north wing must be strengthened by steel beams. - Minor layout changes in the existing structure - The pavilions will be gutted and converted into an expanded covered courtyard area - Improvement of the thermal insulation of all building envelope surfaces (roof surfaces, windows, rear-ventilated timber facades, cellar ceiling insulation) - Modernization 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 - Optimization of fire protection and implementation of the school safety concept
