The municipality of Gomaringen intends to expand the Hubland School in two stages.
To this end, the municipality of Gomaringen is currently holding a competition for architects and landscape architects with a subsequent award procedure with the winners of the competition.
For the services of the specialist planning TGA according to §§ 53, 55 HOAI ALG 1-3,8 (HLS), LPH 1-8, optionally 9, a suitable engineering office is sought.
The assignment is to take place in stages. In the first stage, work phases 1-3 are commissioned. The technical planning for building services (electrical) is the subject of a separate contract notice.
The negotiations are expected to take place on 17.07.2023.
The municipality of Gomaringen intends to expand the Hubland School in two stages, which has so far been a single-track branch of the Schlossschule. The school will continue to be run as a branch office, but in the future, in addition to the addition of a train, it will also offer the possibility of all-day care including lunch. In addition, two company apartments for pedagogical staff and for the renovation of the Hubland sports hall are planned.
The necessary rooms of the future two-stream primary school (approx. 180 to 225 pupils) are to be realised in a new building and the existing school building is to be converted, renovated and equipped for all-day operation.
In the overall measure, the current pedagogical and organizational requirements must be taken into account and the possibilities of inclusion and participation must be supported by the structural structure. In addition, the questions of energy efficiency, sustainability and economic management of the site must be answered with the measure in a future-proof manner.
The planning area with a size of approx. 11,304 m² is located on the western edge of the Hinterweiler district, north of the centre of Gomaringen.
Building stock:
The sports hall is a concrete building from 1974. As part of the building's maintenance, individual structural and technical improvements have been carried out again and again over the course of time. Nevertheless, the hall must be fundamentally renovated in terms of energy efficiency, use-specific and building technology.
The building of the current Hubland School is a concrete sandwich building from 1970.
The building technology must be checked and, if necessary, renewed in the course of the conversion. During the conversion, measures may have to be taken to prepare the building for connection to the local heating network.
Planning is expected to begin in Q3 2023.
The areas of the school building comprise approx. 2,000 m² GFA for the new building and approx. 660 m² GFA area in the existing building. The stock of the sports hall comprises approx. 700 m² GFA. The sports hall is to be renovated or can also be rebuilt in parts.

Lebenszykluskosten:
Through structural and technical measures, an optimized ratio of investment costs to usage costs is to be striven for. The design concept shall take into account the production, operating and maintenance costs by:
- the appropriateness of the structural measures (especially space efficiency, building shape, supporting structure, façade, etc.)
- low energy costs due to reduced energy demand and optimized energy demand coverage
- easy to clean and maintain the façade
- the avoidance of maintenance-intensive building technology,
- a maintenance-reduced design of the open spaces, taking into account climate-adapted planting
Energy demand coverage:
The municipality is currently investigating whether a local heating network can be planned and built in the area of the Hubland School, to which the school and the sports hall will also be connected. Therefore, no statements on the heating of the building are required in the context of the competition.
Provision must be made for the use of photovoltaics, including electricity storage. Façade surfaces can also be used for this purpose.
Sustainability:
When selecting materials for construction, building envelope and interior fittings, the awarding authority attaches great importance to considering the life cycle of the building. Both the production of the materials and their installation as well as the dismantling and the possibility of recycling play a role here. This must be addressed in the context of the competition. A high degree of prefabrication of the components is to be strived for. However, it must be taken into account that the construction area is located in earthquake zone III and thus there are corresponding requirements for the supporting structure.
The new roof surfaces are to be designed as green roofs as far as possible for retention. The combination with photovoltaic systems on these areas is expressly desired.
In order to achieve the climate targets, the awarding authority would like to see a conscious use of resources in the production, construction and operation of the building. With the construction, the components and the useful life of the building materials, the CO2 emissions of the building are to be sustainably reduced.
The sustainability criteria according to Sustainable Building in Baden-Württemberg (NBBW) from the State Ministry for Regional Development and Housing Baden-Württemberg must be taken into account in further planning.
The measure is to be promoted.
