Germany – Engineering services – Sanierung Labor- und Bürogebäude Robert-Hooke-Str. 5 am Standort DLR Bremen - Leistungen der Technischen Ausrüstung ELT, ALG 4, 5, 6 und 8, Leistungsphasen 2-3, 5-8 gemäß §§ 53 ff. HOAI

The DLR facilities in Bremen are currently distributed across 7 buildings in the Technology Park. Only two of these are owned by the DLR. Therefore, neither a uniform access control nor adequate security monitoring is possible. In addition, laboratory capacities and storage spaces have been lacking for several years. The installation of containers in the outdoor area and the rental of external rooms only solve the problem inadequately. The vacant neighboring building immediately next to the DLR Institute building offers a solution for the missing areas. Since the previous owner had occupied the building for over 30 years, all surfaces and the technical equipment need to be renewed. The fire protection requirements are no longer met structurally. Additional adaptation work is required for the setup of laboratories and desk-sharing workstations, as well as barrier-free accessibility. The following institutes are planned users:

1. Institute of Space Systems - Departments: Planetary Exploration Systems, Planetary Infrastructures, Digital Clean Rooms

2. Institute of Satellite Geodesy and Inertial Sensorics – Department: Relativistic Modelling

3. Management Department LS Bremen / NF according to DIN 277 = NUF 1-6 approx. 1,723m2; GFA approx. 2,602m2

Planning task: The three-storey building at Robert-Hooke-Str. 5, which was approved in 1991, constructed, and extended three times, was used by the "German Research Center for Artificial Intelligence" for the last 30 years. The building was constructed in solid construction with a brick facade, with the 2nd floor set back behind the head building and clad with a zinc sheet facade. The exterior walls consist of load-bearing masonry, and the floor slabs are supported as horizontal slabs by reinforced concrete internal supports. Load-bearing internal walls are only present in the staircase area. The sanitary core consists of solid, non-load-bearing walls. The further interior construction was carried out in dry construction. The roof of the 1st section consists of a flat, insulated construction with a zinc sheet covering. The head building consists of a flat roof. 1994 first extension in the form of an extension of the office area. 2001 addition of the main entrance with an open, glazed entrance canopy. 2008 annex of a single-storey, approximately ten-meter-high exploration hall as a workshop in the rear area of the property. This consists of a steel structure with metal sandwich elements and a flat roof. All surfaces in the interior of the building are to be renewed due to the long period of use, and the technical equipment is to be upgraded to the latest standard. The requirements of structural fire protection are no longer met. Additional renovation work is required for the setup of laboratories and desk-sharing workstations, as well as barrier-free accessibility and use. For the implementation of the new floor plans, drywall walls are to be dismantled and partially renewed. Sustainability / energy renovation of the building envelope: In its 599th board meeting, the board decided that DLR buildings should be operated in a climate-neutral manner by 2035. Furthermore, buildings that are renovated are to be certified according to the Sustainable Building Assessment System (BNB) with the quality standard "Silver". However, the board of the DLR had already decided on the purchase and renovation of the building RHS5 in its 597th board meeting - two meetings earlier. The present PJK therefore does not take into account any energy renovation according to GEG, since the facade and the roof are still in very good condition and do not require renovation and should therefore not be changed. Therefore, the costs for energy upgrading are not included in the present cost framework of the PJK. Due to the decision of the board, the building RHS5 will now also be energetically renovated. Parallel to the planning phase of the actual renovation and refurbishment measures, the sensible energy upgrading of the facades and the roof, the implementation of a PV system, as well as the renovation of all building services components will be examined according to the requirements resulting from the application of the GEG and the BNB certification. A specialist planner has already been commissioned for this examination. A first building physical assessment has already been created. However, it is essential that the renovation and commissioning of the building RHS5 must not be delayed by these measures, as the planned commissioning must take place in 2029 due to already terminated lease contracts of other properties. Design planning: 08/2026-04/2027, tendering: from Q1 2028, execution: Q3 2028-Q4 2029 Start of building operation Q4 2029/ completion of measure Q1 2030

The total costs are divided as follows: (cost framework net) KG 300: 963,712 €; KG 400: 816,880 € (KG410: 42,750.00 € KG 420: 10,000 €, KG 430: 177,000 € KG 440: 224,800 €, KG 450: 250,000 €, KG 460: 50,000 €, KG 470: 13,000 €, KG 480: 30,000 €) KG 490: 19,330.00 €, KG 500: 99,870 €; KG 600: 8,000 €

It is intended to award the following services: Services of the TGA - ELT, ALG 4, 5, 6, 8; LPH 2-3, 5-8 according to §§ 53 ff. HOAI Initially, in stage 1, the LPH 2+3 according to § 53 HOAI will be commissioned. The LPH 5-8 will be called up step by step. There is no legal claim to a total commission.
