As part of the conversion/revitalization of the Columbus Cruise Terminal, the specialist planning services for the technical building equipment will be put out to tender. Initially, the service phases 1-3 are to be commissioned. The client reserves the right to successively commission further service phases.
Certification in accordance with the DGNB assessment system is planned and is the aim of the planning. Low primary energy consumption as well as the optimisation of life cycle and management costs play an essential role in the holistic implementation of the "best possible building".
The building is an ensemble of buildings from the 1950s/60s consisting of a 3-4 storey central building, a 3-storey north wing (a south wing was never realised after construction). To the east of the central building is a 6-storey office building with the heating centre in the basement and the former entrance hall to the cruise terminal.
As part of a competition for the awarding of the planning services, the client decided to revitalise the existing building ensemble and add to it accordingly. To this end, the existing building fabric is to be used sensibly in terms of sustainability, and additional areas are to be supplemented in a sustainable and demand-oriented manner. The preliminary design concept envisages that the future development of the Columbus Cruise Terminal will again take place centrally from the east, i.e. the so-called central building. Following the idea, it is planned to create the required parking spaces in a parking pallet in the east. A skywalk provides access to the Columbus Terminal at several points in the same way. The existing high-rise building is to be renovated and modernised in terms of energy efficiency and, in a possible further step, to be extended in accordance with the original idea. The current concept of the project planner provides for a modular construction. The final decision on the modules to be implemented can only be made as part of the planning process. Therefore, a module-by-module bid submission is required.
Certification in accordance with the DGNB assessment system is planned and is the aim of the planning. Low primary energy consumption as well as the optimisation of life cycle and management costs play an essential role in the holistic implementation of the "best possible building". In the planning and implementation of the project, the concerns of flood protection, the existing infrastructure and the cruise operation to be guaranteed in all project phases are of particular importance. Decontamination must also be taken into account.
The current ventilation of the north end is provided by three ventilation units on the 1st floor from the renovation year 2003. The chiller on the roof of the northern office wing, which was departed around 2017, ensured the air conditioning of the terminal via the latter. In the future, for example, this would have to be done via the mid-level staff for the entire terminal. The north head is currently heated by two gas boilers with a maximum capacity of approx. 400 KW and 1100 KW. The control of the entire building technology is carried out via the outdated Landis & Staefa PRU 10.64 regulations. The high-rise office building and the central building are heated by two gas boilers with up to 580 KW and 720 KW output, Landis and Staefa PRS 10.82 control and Landis & GYR RWP 64.91 boiler control. The ventilation system in this area has been taken out of service in the past and would have to be redesigned accordingly. Instantaneous cooling is provided in some areas by split air conditioning units. It is desirable that the future TGA technology can meet the requirements of a CO2-neutral port. In addition, the client attaches great importance to the fact that consideration is given to the historic interior design that is worth preserving and that the location on site is correctly assessed. Therefore, it is necessary for the contractor to plan innovatively and with foresight. There must be close coordination with the property planner as well as the other specialist planners, as the existing premises are not always suitable for the conventional solutions.
Due to the plans for the design of converter systems for the supply of shore power to seagoing vessels during layovers, the Columbus quay currently has the following possibility: Arrangement of a possible container-based modular converter system on the possible future area of the parking pallet east of the building. Each cruise ship (6.5 MVA) releases waste heat energy of approx. 200 KW during plant operation. With 3 ships moored at the quay at the same time, waste heat energy of up to approx. 600 KW is generated. The existing electrotechnical installation systems in the MB are holistic.
The electrical installation of the office building is designed for use and corresponds to the required state of use.
