New construction of the Kronshagen utilities
VE304 steel and metal work_metal facade
The entire construction project includes the construction of a new administration building, consisting of a two-storey head building with a basement and a single-storey bar, as well as a company hall with workshops and laboratories on the Claus-Sinjen-Straße 31 property in 24119 Kronshagen.
Administration building:
It is a two-part structure, consisting of a two-storey head building facing east-west with a facade made of red facing masonry and a single-storey north-south facing beam that connects to the north side of the head building.
The administration building is accessed via a staircase with lift system at the junction of the two buildings. Employee access is located in the inner corner, which leads directly to the central staircase. The sanitary facilities are located adjacent to the staircase and are therefore centrally located, and can be accessed via a hallway from the staircase. In addition to a wheelchair-accessible toilet, toilet facilities are located there as individual cells that are equally available to employees and customers. The arrangement of the sanitary facilities as individual cells serves the flexibility and sustainability of the building. In addition to the possible adaptation to the employee relationship of men and women, it would be possible to set up a toilet for non-binary people without much effort.
The two-storey bar has a basement, in the basement of which the technical and storage rooms are arranged. On the ground floor, on the west side, is the main entrance for customer traffic, which is accessed from the customer and employee parking lot. The windscreen of the customer entrance is followed by a corridor with a waiting area, connected to it are the reception, the shared service consultation areas and its management office. A meeting zone is opened up behind a double-leaf door. The area of the meeting rooms is designed without columns with mobile partitions in order to make the area usable as one large room.
On the upper floor of the head building are the higher-level management rooms with secretarial office, accounting, etc. and a meeting room. From the staircase on the upper floor, you have access to a roof terrace on the single-storey bar. The roof terrace acts as a second structural escape route via an external staircase.
The single-storey beam on the north side is aligned at 90 degrees to the head building and is given a metal façade made of profiled sheets in a similar look to the company hall. The bolt is accessed from the centrally located staircase via a mid-floor, so that the offices on the facade side receive optimal lighting due to the east-west orientation. The offices of the individual divisions (gas, water, electricity) and a kitchenette are located there.
The entire structure is designed as a solid construction with reinforced concrete or masonry walls and load-bearing internal columns. The storey or roof ceiling is a semi-prefabricated ceiling made of filigree slabs with in-situ concrete addition. With the exception of the roof terrace, both roofs of the administration building are designed as intensely green roofs. This measure is necessary for the water balance to be achieved as the area of the evaporative component.
Floor area: approx. 550 m2
Gross floor area: approx. 1,180 m2 (area R and S)
Gross volume: approx. 3,700 m3 (range R and S)
Operation hall:
The company hall is located west of the administration building in site 2 of the valid development plan and is connected to the administration building by an open, covered walkway. The technical and building connection rooms, as well as workshops and warehouses, are located on the northern outer wall. Due to the sound insulation report, which was produced in the course of the B-Plan process, the northern exterior windows cannot be opened for emission protection. The rooms are mechanically ventilated and vented.
The warehouse with parking spaces for loading and unloading is located under a raised part of the roof. A 2-level rack warehouse will be installed on the area as a complete system.
In the energy concept, the aforementioned ranges are set as low-heated areas (12°C - 19°C).
Within the building envelope of the company hall, the changing areas, each with a black or white lock and adjoining sanitary rooms, are housed in a solid brick core. On the western side of this massive part, there is a large room that can be used as a rest and break room and training room. This area can be divided into 3 rooms by means of mobile partitions. In the energy concept and technical equipment, these rooms, including the changing rooms and sanitary areas, are regarded as rooms with a normal indoor temperature (>19°C).
The hall is planned as a steel structure with a facade made of sandwich panels. The masonry walls of the normally heated rooms are not load-bearing walls within the hall. The raised roof area above the rack warehouse is completely occupied by a PV system, which is necessary to achieve the planned energy standard (BEG 40).
Under the PV system, the flat roof is designed as a warm roof with foil or bitumen waterproofing. The lower roof area is designed as an extensive green roof, which is also part of the water balance calculation.
Floor area: approx. 645 m2
Gross floor area: approx. 645 m2 (area R and S)
Gross volume: approx. 2,630 m3 (range R and S)
ancillary facilities:
The depot with its traffic and storage areas extends south-west of the company hall. A vehicle shelter with 16 parking spaces for the company vehicles will be built on the traffic area in the western area. This is a galvanized steel construction that supports a butterfly roof that cantilevered on both sides. The roof is designed to accommodate additional photovoltaic elements.
On the southern boundary of the property, according to the B plan, a storage area closed and covered on three sides will be manufactured as a steel structure with a facade made of profiled steel sheets. The rear wall of the storage area forms the soundproofing wall prescribed in the development plan. The roof must also be designed as an intensively green roof area for the water balance balance.
Base area: approx. 812 m2
Gross floor area: approx. 812 m2 (area S)
Gross volume: approx. 3,080 m3 (range S)
