The following description refers to the overall project to be realized. Further explanations on lot-specific procurement are specified in II.2.4.
Vattenfall Wärme Berlin Aktiengesellschaft operates a district heating system in Berlin consisting of several district heating networks with a total length of approximately 2,000 km and 10 large generation sites as well as a large number of smaller heating plants and CHP plants with a total generation capacity of around 5,000 MWth and around 2,350 MWel. In addition, a refrigeration network with a length of approximately 10 km and an output of around 40 MWth is operated. Approximately 1.3 million households are currently being supplied with heat across the entire district heating system.
The aim of the “System Control Center” project is to construct a new KRITIS system room with workshop, warehouse and office space in an existing building and the construction of a new one-storey building, the so-called “technical building”.
The necessary planning is largely carried out by an already commissioned planner.
The procurement project is divided into 4 main lots:
Lot 1: Technology & Construction (separate TED release)
Lot 2: Waitentechnik (separate TED release)
Lot 3: waiting room equipment
Lot 4: High current (separate TED release)
An existing building from 1970 will be used as the future location of the system station in Berlin. This has a footprint of approx. 78.68 x 78.68m with a height of approx. 12m. It consists of two floors and has been used so far as a waiting & switchgear, among other things. In the run-up to the activities advertised here, the building is gutted to the shell construction except for the roof and façade cladding. The future technical building is single-storey and is planned with a floor area of approx. 36.51 x 9.26 m and a height of approx. 6.90m.
In the future, all actions to manage, monitor and optimize the district heating system described above should take place from the system station. The district heating system in this context consists of all heat and power generators as well as district heating networks within the Berlin supply area.
The prerequisite for achieving this goal is the integration of all producers distributed across Berlin's urban area (heat and electricity) and all components of the district heating network into the newly built system station.
A boundary condition is the continuation of decentralized maintenance of the generator plants and the continued function of the district heating network today, which is to be converted to a reserve station for the district heating network later on.
The combination of local maintenance into the common system room results in the classification of the district heating system as a critical infrastructure. The resulting CRITIS requirements - failsafe operation and availability - must be taken into account at all times during the planning and construction of the system station.
The system maintenance complex includes the control room (approx. 1000 square meters, 20 workstations) as well as server and side rooms. In total, around 120 workers will work in shifts in the system maintenance complex.
The adjacent workshop, warehouse and office space is designed for around 150 employees with a scope of around 6,000 m² of usable space.
In total, it is a detached existing building with approximately 51,000 m³ gross volume (BRI) and approximately 9,800 m² of gross floor area.
In the current phase, the issuing body needs suppliers to deliver supplies and services from different technical departments to implement the described project. The specific scope of services is described under point II.2.4. The start of performance is planned for the beginning of Q2/2022.
Lot 3 “Waiting Room Equipment”This publication applies exclusively to lot 3 “Waiting Room Equipment”.
In order to provide the applicant with guidance for the required scope of services, services are listed below in part according to the current planning status of the project. This is a planning status that can be adjusted in the course of the project if necessary.
It is to manufacture, deliver and assemble the furnishing for the control room on site. This includes especially
o built-in wardrobes,
o sideboards,
o operating tables,
o Holding device for screens including accessories and other furnishings
The assembly takes place partly on raised floors and substructures up to subfloor
