The contract includes the technical equipment planning in accordance with Part 4 Section 2 HOAI AG 1-9,
Work phases (LPH) 5 to 9 for:
- Plant group 1 sewage, water and gas plants,
- Plant group 2 heat supply plants,
- System group 3 ventilation systems,
- System group 4 high-voltage systems,
- Plant group 5 telecommunications and information technology systems,
— system group 6 lift systems,
— plant group 7 commercial plants,
— plant group 8 building automation.
A phased commissioning of services from the LPH 5-9 is planned.
For the all-day operation of the Ludwig Riedinger Kandel primary school, a two-storey new building with a cafeteria and all-day rooms is to be built.
The selected structure along the northern property line creates the hitherto missing completion of the courtyard area in terms of urban planning and thus forms a room edge to Marktstraße.
In the eastern area, the passage from Marktstraße to Kirchgasse is still available for public residential traffic. The kitchen is also delivered there, but is completely separated from the schoolyard by a fence.
The independent extension will be accessed via an access from the schoolyard. The foyer has the stairs to the upper floor as well as the toilet facilities and the lift. The foyer leads directly to the dining room with a cloakroom and food distribution. The dining room opens onto the schoolyard to the south via generous window elements, so that the outdoor area can also be included in the warmer season. On the east side of the building, the kitchen area with clear black and white separation as well as the ancillary rooms for staff and building services are arranged.
On the upper floor there is the all-day room, the integration rooms as well as the multi-purpose room and a work room. The corridor provides access to the 2nd structural escape and rescue route as well as the external seat staircase that opens up to the schoolyard.
After the variant study dispensed with a basement level, the flat roof of the building houses the ventilation systems with appropriate housing and a PV system. The building is supplied with heat from the existing building via an air-water heat pump.
A ceramic curtain wall in combination with a thermal insulation composite system is provided as the outer wall cladding.

Project objectives Technical equipment:
,
A. Project objectives Water, waste water, heating, ventilation Simple, easy to operate and maintain systems are strived for.
The overall concept for the buildings should be evaluated in terms of energy, operational and economic optimization potential. In principle, investment costs for building services must be set in an appropriate proportion to their savings potential.
The required control technology should be kept as low as possible and be low-maintenance.
Heating The aim is to achieve a high level of thermal comfort. The group rooms are to be heated via radiators with thermostatic valves. A central temperature reduction at the heat generator is desired outside the useful life.
