The city of Herrenberg intends to rebuild and expand the natural science area and to refurbish the building stock of the Andreae-Gymnasium in Herrenberg.
The space program covers approx. 1 800 m
The costs are currently estimated at EUR 2.8 million net KG 300 + 400.
Construction is scheduled for spring 2021.
For the services of structural engineering acc. §§ 49, 51 HOAI LPH 1-6, optional LPH 8, a suitable engineering office is wanted. The commissioning should take place gradually.
The city of Herrenberg intends to rebuild and expand the natural science area and to refurbish the building stock of the Andreae-Gymnasium in Herrenberg.
The entire NW area of the high school is to be restructured and supplemented by multi-surfaces. These necessary school room areas according to the current school promotion guideline can not be accommodated in the building stock, therefore a structural extension of the school on the competition property becomes necessary. The general classrooms should continue to be maintained.
When redesigning the extension, the connection to the building stock as well as the educational and organizational requirements should be considered accordingly.
For the accommodation of the room program areas are the extension, as well as the entire, northwestern part of the building of the Gymnasium available. The building structure should be preserved. The remaining parts of the gymnasium, the cafeteria and the two sports halls remain in their function and use.
In addition, the task includes the creation of a façade concept for the entire school building from the 1970s and the extension building from 2001. The refurbishment is to be planned for the entire ensemble of buildings and is to be implemented on a building-by-building basis.
At present, an architect competition is being carried out, which is expected to be completed in 2019. Proposals are to be made in the competition on how to implement the restructuring and general refurbishment with as little intervention as possible in everyday school life. For this purpose, the architects have to show a concept of the individual construction phases.
An up-to-date subsoil report has been prepared for the property.
Excerpt from the subsoil report - Slope water:
(...) Due to the slope of the property, it is not possible to keep the slope water at its current levels after further structural interventions. The water is therefore to be seized via drains and derived via the existing drainage. (...) Excerpt from the subsoil report - Foundation:
(...) To achieve a uniform settlement behavior, the burdens of the construction project in the semi-solid marl of Lettenkeupers (west side) and the friable dolomite stone of the Upper Muschelkalks (east side) are removed.
On the west side, it may be appropriate to provide a foundation on pile-like foundation bodies, if the given earthquake zone allows. On the east side can be founded on pile-like foundation bodies or on cased bored piles. (...).
The technical planning TGA (HLS) / or TGA (electric) is the subject of a separate contract notice.
At the moment there are parallel tenders for the extension of the Vogt-Heß-Gemeinschaftsschule.
