Partial general contractor services (shell construction and building envelope)
LOT-0001
New construction of the comprehensive school with sports hall in Krampnitz - partial general contractor services (shell construction and building envelope).
A modern urban quarter is being developed in Krampnitz with approximately 4,400 housing units for around 10,000 residents and areas for social infrastructure, commerce, trade, and services. With the occupancy of the first apartments in Krampnitz, initial infrastructure facilities are also required. According to the urban and landscape planning master plan, several daycare centers and school locations are planned, including a 6-stream comprehensive school for 900 children with a quadruple sports hall and outdoor sports, play, and green spaces.
The planned space program encompasses a total usable area of 10,800 m2, divided into approximately 7,600 m2 of usable space for the comprehensive school, which includes a youth recreation facility, and approximately 3,200 m2 of usable space for the construction of a quadruple sports hall with a sports functional area.
The building will be founded on a flat founding with a ground slab, strip foundations, and individual foundations.
The structural framework of the school building will be designed as a skeleton construction using precast reinforced concrete elements. A system of concrete columns and concrete beams made of prefabricated elements with standard dimensions provides maximum spatial flexibility.
The partition walls between the rooms and the access areas will primarily be made of non-load-bearing lightweight walls.
Wood-concrete composite ceilings made of solid wood will fill the bays of the concrete skeleton. Ceiling and roof slabs will be designed as plate-like structures. The floor slabs will receive a floating screed construction for impact sound protection. The structure of the sports hall will be formed by glued laminated timber beams in the transverse direction of the hall.
The roof structures made of solid wood elements will receive a green roof construction with extensive green cover. Additionally, a PV system harmonizing with the green roof will be installed on the roof area.
The facades will be constructed from highly insulating wooden frame building elements with inserted wooden window constructions. The wooden frame building elements will be clad externally with a ventilated shell made of pre-greyed larch wood profiles, and internally with 3-layer boards insulated.
Summer heat protection is ensured by external sun protection systems, thermally massive heavy floor constructions, and effective night cooling.
The terrace areas will have different surfaces but will predominantly feature a concrete slab surface.
A pergola made of galvanized steel posts and beams will form the urban spatial edge above the sports hall on the roof of the changing room area of the sports hall.
The building will be constructed from robust and durable materials. Massive components will largely remain unclad to activate them as thermal storage, thus improving the thermal stability of the building. Linoleum floors in the classrooms, lightweight walls partially with wood surfaces, as well as acoustic ceilings made of wood wool panels contrast with the mineral surfaces of the usable screed floors in the access areas.
Concrete and wooden walls will remain visible.
In planning and construction, only materials and components that have high health and environmental compatibility and a long service life will be used as much as possible. The building materials are generally recyclable or biodegradable.
To meet the room acoustic requirements, acoustic ceilings made of wood wool panels are planned.
The school building will be designed to be accessible.
Extensive sports facilities will be constructed in the outdoor area, including a competition track with a grass sports field. Additionally, an artificial turf field, several small field playing areas, and a large break area with different quality of stay will be created. A separate outdoor area for the youth recreation facility will be implemented.
The entire school grounds will be fenced and will receive extensive greenery and various ball catch systems for the sports areas.
The rainwater is to be allowed to percolate on the property. It is planned to distribute rainwater via a drainage system and to percolate it through a retaining horizon. Combined with tree pits, this creates the opportunity to water the trees and improve the local microclimate.
