Germany – Engineering services – Modernisierung Betriebskantine Stuttgart - TGA ELT Leistungen der Planung der Technischen Ausrüstung, Anlagengruppen 4 und 5‚ Lph. 2-9 gemäß §§ 53 ff. HOAI

1.1 Renovation and expansion of the canteen as a temporary measure: The existing dining room, including the kitchen in the northwest wing of Building A, will be upgraded and expanded. The alcove, which can be separated by a mobile partition, will be replaced by a drywall partition to create a vending machine room that is separately accessible from the corridor. Due to its immediate proximity to the dining rooms, the vending machines are optimally positioned and easily accessible to all employees. A decentralised ventilation unit will be installed in this room to ventilate the adjacent dining room. To remedy hygienic deficiencies and to cover the space requirement, two additional kitchen containers will be installed in the outdoor facilities and professionally connected to the facade via a weather-resistant enclosure. The delivery access will be extended to the container location. An office will be converted into a changing and shower room for women. The existing women's changing room will be converted into a separate men's changing room and a barrier-free unisex toilet. To ensure air quality, both dining rooms will be equipped with decentralised ventilation systems. To reduce the high noise levels during lunch, acoustic ceilings and, if necessary, sound-absorbing elements on the walls will be provided. Outdated kitchen units will be replaced by new or stored appliances; the undersized extractor hoods in the kitchen and scullery will be replaced. The existing dishwasher and grease trap will be examined for their capacity limits and any need for renewal in connection with heat recovery in terms of amortisation. The adjacent former laboratories in the west wing will be integrated into the dining room extension. There, interior walls, suspended ceilings, including old installations and floor coverings, will be dismantled without interfering with the load-bearing structure. An expanded dining room with media technology, mobile partition, and two storage rooms will be created. A window element will be dismantled in favour of an emergency exit door; the rest of the outer shell will be preserved. 1.2 Conversion of laboratories into offices: In the west wing, adjacent former laboratory areas will be converted into four single offices. Existing interior walls, floor coverings, and old installations will be dismantled. The new offices will be equipped with plasterboard walls, new floors and ceilings, and media equipment according to the DLR guidelines. 1.3 Conversion of the library archive into a lobby: The existing library archive will be converted into a lobby. Rolling archive systems, shelving systems, and built-in cabinets will be dismantled. Depending on the condition, the wooden wall cladding and carpet coverings will be dismantled for a non-toxic new construction. After a static test, a fixed glazing will be installed in the partition wall to the singers' hall to break up the room structure and improve the light incidence. Wall and ceiling surfaces will be renovated according to a new colour and lighting concept. A modern tea kitchen with built-in furniture, sink, and electrical appliances (induction hob, refrigerator, dishwasher, coffee station) including the necessary media connections will be integrated. 1.4 Fire protection measures for the singers' hall: To ensure fire protection, the singers' hall on the ground floor will be separated by an F30 glass wall with an integrated T30 door. The larger part will be usable as a multi-purpose room. The smaller part will serve to separate the staircase, thereby converting the open staircase into a legally required enclosed staircase. In the basement, the staircase to the corridor will also be secured with an F30 wall and T30 door. 1.5 Optional renovation measures due to updated floor layout: The office use of the departments will be reordered according to the agreed floor layout. Depending on the requirements, offices will be divided or combined by light partitions. This also includes the dismantling of built-in cabinets and the adaptation of door openings. Only services that are not covered by existing framework contracts will be procured externally. Purely decorative measures such as painting work or the preparation of existing floors are not part of the measure. The contracting authority reserves the right to carry out the individual measure "Restructuring floor layout" in whole or in part itself. In this case, the fee for this individual measure will be waived according to the agreed scope of services. The costs (KG 200-600, as of March 2026) for the measure are estimated at approximately 1.23 million € gross. The milestones for implementing the project provide for the planning to begin in October 2026. It is planned to start construction in mid-2027 and to complete it in early 2028. It is intended to award the following services with this tender: Services for the planning of the technical equipment, plant groups 4 and 5, Lph. 2-9 according to §§ 53 ff. HOAI. Initially, in the awarding stage 1a, the performance phases 2+3 (preliminary and design planning) will be awarded according to § 55 HOAI or according to the appendix of the contract.
