Redevelopment

Under a reorganization is understood in the structural and civil engineering technical restoration or refurbishment of a building or of several buildings ( up to entire neighborhoods ) to eliminate damage and / or to increase the living standard. Often the energy efficiency main goal of rehabilitation, sometimes a useful adaptation (for example, barrier-free living ).

A renovation goes beyond maintenance and repair. You can have a significant interventions in the building fabric include (for example the demolition and reconstruction of entire facades) and usually implies a modernization. The refurbishment of the ground substance of monuments then comes into question if the maintenance of the building is compromised. According to the memorial monument protection authority shall establish the boundary between the substance -preserving restoration and the reversible restoration in these far-reaching interventions in the monument.

Goal of rehabilitation is to restore the standing safe and earmarked usable state. To determine existing deficiencies, is often made a preliminary study ( opinion), the names causes of damage, the damage pattern describes and suggests remedial measures.

Building renovation

Under building renovation or building renovation means the thorough repair or replacement of components, building sections or the entire building. For buildings that were built before the Second World War, one also speaks of old buildings.

Typical remediation measures for the building are:

• Roof renovation for pitched and flat roofs usually referred to not only the replacement of the roof covering and possibly of the entire roof structure, but also the installation of thermal insulation in the sloping roof surfaces, as well as the conversion of the attic space to the attic. For the roofing are just increasingly historical roof tiles, like the monk - nun - coverage used in the field of historic preservation. Sometimes there are still tiles manufacturers, nachfertigen the ancient tile patterns based on the original. In some brickworks there are hand-molded departments can nachfertigen default the brick and roof tile according to ( historical ).
• Ceiling beams rehabilitation usually referred to the renewal of the wood beam ceiling through reinforcement or replacement of components.
• Energy renovation or thermal remediation usually referred to the upgrading of the thermal envelope of a building to minimize the heating demand, as criteria of energy standards.
• Facade renovation, reconditioning of the facade, now often includes their energy refurbishment
• Keller neck rehabilitation usually referred to the renewal of the vertical structural waterproofing below ground level and / or the horizontal seal against pressurized or non-pressurized ( storage ) water.
• Window restoration refers to the replacement of old windows with new windows, also from the point of thermal remediation (in exceptional cases it means a carpenter moderate revision of a window and / or equipping of a window with better insulated glass)
• Masonry reconstruction usually referred to the exercise (gain ) or replacement of damaged or impaired in their bearing capacity of masonry parts or exposed masonry surfaces. ( the attack by dry rot )
• Concrete repair usually referred to the repair of damaged or impaired in their carrying capacity of concrete structures or concrete surfaces.
• Asbestos removal usually referred to the removal of hazardous asbestos materials or its replacement with safer materials with similar fire protection technical properties.

Special forms of rehabilitation

• Structural restoration - restoration of the building fabric
• Reconstruction - Renewed manufacturing
• Translocation - transfer, thus reducing faithful to the original structure at another location

Urban regeneration and urban renewal

Urban rehabilitation and renewal go beyond the renovation of individual buildings and have the elimination urban flaws and often social ills in urban areas to target, which are then explained to redevelopment areas. Consequently, the term urban renewal or redevelopment district means the implementation of comprehensive planning and building regulations legal measures to improve the quality of a city area. The basis for this restoration form the reorganization law in the Building Code. See also urban planning.

Follow renovation

Therefore, the restoration of such district is often accompanied by social displacement of entire populations. If this happens on a large scale and without compensating the risk of Slumbildung or ghettoization in the outskirts neighborhoods with lower construction standards.

Since the standard of the renovated quarters by the measures significantly increases ( remediation objective ) also increasing rents ( on the other hand fall through energy refurbishment heating costs ). Higher hot rents can have a high social status of the residents structure and result to showcase or noble quarters. Further information on this in: gentrification.

Redevelopment area

A redevelopment area may be established since 1971 in accordance with the Building Code as Urban redevelopment by the municipality formally, if described in the Building Code deficiencies in a district were observed.

First, no formal redevelopment area of Germany before this time is called by large-scale demolition and reconstruction of the resultant to the Rosa - Luxembourg -Platz new city district in general in the 1930s by the Berlin Mayor Ernst Reuter initiated renovation of the barn area. In such a so-called clear-cutting renovations the building entire streets or the whole neighborhood was demolished and everything - usually including infrastructure - roads, water, sewage - rebuilt.

Against this clear cutting renovations there were up to 1970 times massive citizen protests. With the Urban Development Act of June 19, 1971 began a careful urban renewal. Already by 1990 great success in regenerating city centers were recorded in the West and East Germany. On the occasion of the International Building Exhibition 1984 results were shown in Berlin. The front houses the Berlin block building were renovated and received the rear buildings were to be demolished only in the event of unacceptable living conditions in terms of light, air and sun.
