Germany – Engineering services – Neubau "Haus für Menschen mit Behinderung", Bietigheim - Elektroplanung

The building structure for the "Haus für Menschen mit Behinderung" (HfMmB) is planned as an extension of the Seniorenzentrum as a gabled roof house with 3 storeys. The ridge line in the north-south direction corresponds to the overall ensemble and continues the traditional building structure along the Wilhelmstrasse. To the west of the building, there is a 3-storey balcony structure in metal construction, which expands the living areas of the residential groups. The open space develops opposite the outdoor areas of the adjacent day care centre to the west, promoting a spatial and social connection between the resident groups. On the eastern entrance side, the partial plot is connected with a public thoroughfare, which leads to the northern Kirchstrasse. The eaves height is set slightly below the contour of the planned Seniorenzentrum at +9.50m, as a raised ground floor can be dispensed with. The roof pitch and ridge height are approximately the same as those of the Seniorenzentrum. A precise plot formation in delineation from the adjacent ensemble has so far only been made in the sense of the scope of the B-Plan. There, a distinction is made between the project-related and the offer building plan part. In the sense of the overall project, easements will have to be agreed, for example for the thoroughfare and the position and development of the ancillary facilities for waste and bicycles.

Uses

• 3 residential groups with 6 residents each (18 residents)

• each room with its own barrier-free bathroom (level-access shower 120x120cm)

• room widths of 3.25m (>3.20m), room size 16.90m² (>16.00m²) cf. LHeimBauV0

• living area of 45m² for 6 residents

• 1x care area on the ground floor

• 5 apartments, which can be accessed separately from the staircase

• partial basement with technical areas, storage areas, WC visitors, IT, laundry room, laundry etc.

• A connection to the underground car park of the Seniorenzentrum has been abandoned for cost reasons

• technical areas (heating and electrical) according to the specifications of the specialist planning fire protection

• The building is classified as GK3

• staircase (necessary staircase) as 1st escape route

• 2nd escape route via mobile ladder with extension ladder (OK FFB 2.OG< 8.00m)

• distance to the public traffic area <50m

• additional possibility of access via escape balcony at the end of the corridor 1st and 2nd floor

• parking area for the lifting rescue vehicle on the public traffic area (Wilhelmstrasse)

TGA

The energy concept is to be evaluated according to the specifications of the changed client, inter alia, with regard to the targeted energy standard, the ventilation systems and/or certifications. So far, a solution with a heat pump (air-water) as an outdoor unit has been envisaged. A corresponding installation location in the open space would still have to be defined, as there is no flat roof above the 2nd floor available for this purpose.

Structure

The building structure with regular load-bearing axes at a distance of 4.00m in conventional solid construction represents an economical solution. The solid flat ceilings (approx. 22cm), load-bearing partition walls with 20cm (possibly 24cm staircase in the sense of sound insulation), as well as load-bearing exterior walls in 20cm silicate brick + external thermal insulation composite system form the structural base structure.

• Above the 2nd floor, a flat ceiling in concrete would be sensible, which is insulated on the top, in order to create a compact building envelope and to avoid suspended ceilings in high interior spaces.

• The gabled roof shape would therefore be produced by means of a superimposed roof truss in wood.

• The balconies/loggias are designed as self-supporting steel structures (optionally also with concrete slabs on Isokorb in the 1st and 2nd floor) independently of the main building body.

• The foundation is carried out via strip and individual foundations in coordination with the soil report.
