The planned measure involves the installation of internal elevators in the stairwell of the 5-storey prefabricated buildings (plus the basement) in the following objects and house entrances:
- Ascherslebener Str. 3 and 8;
- Coimbraer Str. 2 and 9;
- Friedrich-Ezekiel-Str. 13, 14, 15 and 16;
- Staßfurter Str. 43 and 44;
- Wernigeröder Str. 1 and 10;
- Zeitzer Str. 19, 21, 22 and 24.
The measure is cross-street, but spatially connected in the urban area Halle-Süd.
The primary goal of the measure is to install 1 elevator in each of the house entrances mentioned in the existing stairwells. The electrical power supply is supplied by the local energy supply company EVH.
It should be noted that the building has an existing electrical installation, which does not comply in all parts with the currently applicable standards and regulations, but is subject to the "existing protection".
- Coordination of the new house connection boxes together with Netz Halle;
- disassembly of the old main distributors;
- Installation of new meter systems in a house entrance in free space (10 meter places for apartments, 1 meter places general (HAST, general supply);
- New connection of existing meter cabinets to the new house connection boxes;
- Extension of partial relocation of existing housing supply lines;
- Fire protection of the ELT installation in the stairwell;
- no new installation of apartment distributors, only connection of new apartment supply lines;
- Extension / renewal of stairwell lighting.
Power supply, counting, lines - telephone, antenna
The new meter systems in the KG are fed in from the existing house connection boxes.
The meter cabinets are to be designed in accordance with the EVH technical connection conditions.
Necessary provisionals must be taken into account.
The laying of the new cables from the meter rooms on the respective floors is only possible via the public corridors / staircase. The necessary fire protection requirements (MLAR) must be met.
The services described are to be calculated as finished services, including the ancillary services required for the execution.
It should be noted that the building has an existing electrical installation, which does not comply in all parts with the currently applicable standards and regulations, but is subject to the "existing protection".
In particular, parts of the installation are implemented in the TN-C network form that was common at the time the building was erected.
The construction measure is the basic prerequisite for converting the building installation to the TN-S network (5-wire system).
To identify the TN-C system that is still in place, the PEN conductor must be labeled throughout. The PEN conductor is marked with a sticker on each distribution, each main switch, each outlet.
The meter systems are completely renewed according to the TAB of Halle-Netz-GmbH.
Existing old installations in the apartments are reconnected. It should be noted that this installation is partially made with aluminum as the conductor material.
