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:

- Margueritenweg 37 and 41.

The measure is spatially contiguous in the Halle-Ost urban area.

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".

Partial modernization of the electrical system with the following scope of services:

- Installation of new meter systems per house entrance in open space (24 meter places for apartments, 2 meter places general (HAST, general supply);

- disassembly of old housing supply lines;

- installation of new risers;

- Fire protection upgrading of the new risers in the area of the stairwell;

- no new installation of apartment distributors, only connection of new apartment supply lines;

- renewal of cable network for TK and intercom;

- Renewal of staircase lighting / basement aisle lighting;

- RWA installation;

- Installation of security lighting (ECB).

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.
