In 2013, IBA Hamburg GmbH was commissioned with the district development of the Vogelkamp Neugraben project area in the Neugraben-Fischbek district, which is now well advanced. A total of around 1,750 residential units are to be built here. The basis for the development is the Neugraben-Fischbek development plan (B-Plan NF 65), which has been in force since 2006.

To protect the construction sites to the south of the project area, which are adjacent to the existing S-Bahn and mainline lines, a noise barrier has already been erected between the Neugraben S-Bahn station in the east and the Deutsche Bahn signal box in the west. The upcoming measure is intended to expand active noise protection in the form of another noise barrier section on and west of the signal box.

In addition, the possibility of a photovoltaic system at the new LSW or as a combined LSW with integrated PV system is to be examined. For this purpose, a specialist planner for the PV system is being sought in lot 2.

To protect the construction sites to the south of the project area, which are adjacent to the existing S-Bahn and mainline lines, a noise barrier has already been erected between the Neugraben S-Bahn station in the east and the Deutsche Bahn signal box in the west. The upcoming measure is intended to expand active noise protection in the form of another noise barrier section on and west of the signal box. The requirements of the noise investigation (Annex 3) from 2003 and from the B-Plan NF 65 indicate the need for a noise barrier. The dimensioning of the new noise barrier depends on the planned house typologies, economic efficiency and urban planning reasons (shading). In the B-Plan NF 65 a protective wall of approx. 3.5 m is already specified, which at the same time contains a privacy screen against railway operations:

"In addition, a 3.5 m high noise barrier has been erected over the site along the railway line to protect the residential development possible in the mixed area, which noticeably improves the acoustic situation in this area." (page 52 in the explanatory memorandum).

The new noise barrier to be erected is to start in the area of the signal box and end at the western boundary of the project area in the area 75 m west of the Long Torfgraben. The planned position can be found in the LTU and the function diagram (Appendix 4). Between the Neugraben S-Bahn station and the signal box, a 650 m section of the noise protection measure has already been built. The existing noise barrier consists of precast concrete elements held in place by steel posts. The upper edge of the wall of the approx. 4 m high wall is +10.75 NHN or approx. 2.75 m above the top of the rail, the standard distance between the guards is 5 m. In the area of construction site 0, the ground height is 5.65m above sea level with a subsequent embankment towards the track. With the same upper edge of the noise barrier and track height, the new noise barrier would have to be approx. 5.10m high. The exact height of the upper edge of the wall in relation to the height of the terrain and the top of the rail must be checked and determined in the course of planning. It will also be examined whether the noise barrier can be built closer to the track body and thus lying in the embankment. This would reduce the total amount required. The pylons of the overhead contact line systems, which are located on the lower terrain, are then to be recessed accordingly and converted.

Currently, a new development plan for the area north of the railway areas is being drawn up as B-Plan NF 75, but this is unlikely to result in any fundamental changes to the dimensioning of the noise barrier.

In the area of the planned noise barrier, cables from the railway facilities and various suppliers are to be expected in parts. Existing lines must be requested from the suppliers and the DB.

The proximity to the existing mainline railway facilities with overhead lines (Niederelbe Bahn Hamburg – Cuxhaven) and urban and open space planning aspects, such as the greatest possible preservation of the trees between the cycle path (Annex 4) and the railway embankment and the greening of the noise barrier provided for in the B-Plan NF 65 must also be taken into account as boundary conditions.

As part of the new construction of the noise barrier in the western part of the project area, the possibility is also to be examined whether the construction of a photovoltaic system on or on the new LSW or as a combined LSW with integrated PV system is economically feasible. The test must be carried out in close coordination with a separate PV system planner. This is commissioned via lot 2.

For regular exchange and service provision, appropriate coordination appointments in the planning team are required.

The review is part of this request for quotation. For this purpose, LPH 1 and 2 will initially be commissioned, but the other LPH will be offered as an option. The planning is to be carried out in close coordination with the object and structural planner. The latter shall be commissioned via Lot 1.
