Germany - Technical planning services for mechanical and electrical building installations

Description

Within the scope of the reconstruction/revitalization of the Columbus Cruise Terminal, the specialist planning services for the technical building equipment are put out to tender. The client reserves the right to successively commission further service phases. Certification in accordance with the DGNB evaluation system is planned and the aim of the planning. Low primary energy consumption and the optimization of life cycle and management costs are of major importance in the holistic implementation of the "best possible building". The building is an ensemble of buildings from the 1950/60s consisting of a 3-4 story middle building, a 3-story north wing (a south wing was never realized after construction). To the east of the middle building is a 6-story office building with the heating center in the basement and the former entrance hall to the cruise terminal.
In the course of a competition for the award of planning services, the client decided to revitalize the existing building ensemble and to complement it accordingly. For this purpose, the existing building fabric is to be used sensibly in terms of sustainability, and additional space is to be added in a sustainable and demand-oriented manner. The preliminary design concept provides for the future development of the Columbus Cruise Terminal to be centrally located again from the east, i.e. the so-called central building. Following this idea, it is planned to create the required parking spaces in a parking pallet in the east. Via a skywalk, the Columbus Terminal will be accessed at the same level at several points. The existing high-rise building is to be renovated in terms of energy efficiency, modernized and, in a possible further step, raised in line with the original idea. The current concept of the object planner envisages a modular construction. The final decision on the modules to be realized can only be made during the planning process. A certification according to the DGNB evaluation system is planned and the goal of the planning. Low primary energy consumption and the optimization of life cycle and management costs are of major importance in the holistic implementation of the "best possible building". During planning and project implementation, particular importance is attached to flood protection, the existing infrastructure and the cruise operations to be ensured in all project phases. The current ventilation of the north head is provided by three central ventilation units on the 1st floor dating from the 2003 refurbishment year. The chiller on the roof of the north office wing, which became obsolete around 2017, provided air conditioning for the terminal via the same. In the future, this would have to be provided for the entire terminal via the central building, for example. The heating of the northern head is currently provided by two gas boilers with a maximum output of approx. 400 KW and 1100 KW. The complete building services are controlled by obsolete Landis & Staefa PRU 10.64 controls. The heating of the office tower and the middle building is ensured 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 was put out of operation in the past and would have to be redesigned accordingly. The current cooling system in some areas is split air conditioning units. It is desirable that the future TGA technology can meet the requirements of a CO2-neutral port. Furthermore, the client attaches great importance to the consideration of the historical interior design worth preserving and to the correct assessment of the situation on site. It is therefore necessary for the contractor to plan innovatively and with foresight. There must be close coordination with the object planner as well as the other specialist planners, since the existing premises are not always suitable for the conventional solution options. Due to the planning for the design of converter systems for the sea-going vessel supply with shore power during the berthing times, the following possibility currently presents itself for the Columbus quay: Arrangement of a possible container-based modular converter plant on the possible future area of the parking pallet east of the building. For each cruise ship (6.5 MVA), a waste heat energy of approx. 200 KW is released during plant operation. If 3 ships are moored at the quay at the same time, waste heat energy of up to approx. 600 KW is generated. The existing electrical installation systems in the MB are completely obsolete. The electrical installation of the office building is designed for the use and corresponds to the required state of use.
