Biberach - Riß „Rißegger Steige“
For a new, densely populated single family residence area in the outskirts, the cooperation of all construction parties was coordinated in teams on a trial basis in order to render the entire planning and construction process more effective, improve the quality of the execution and cut costs.

Context
Source: www.Biberach-Riss.de
In Biberach, a medium-sized urban centre with a population of 31.000, an urban plot not previously exploited for construction was developed into a new residential area. The construction site is located approximately 17 km from the town centre on the outskirts on a plateau, in an angle created by two arterial roads. There are single-family residence areas to the north, while in the north-east and east, the project site abuts a strip of forested green space beyond which lie mixed, industrial and larger retail areas.
Project description
Source: www.Biberach-Riss.de
This project was aimed at providing favourably-priced, resource-protecting family housing in a quality neighbourhood. On a gross building land area of 5,8 ha, the 147 residential units created on small plots represent a mixture of 105 single family houses in 8 different building types and 42 apartments. This dense development is arranged in rows oriented to the south in a virtually traffic-free neighbourhood with a centrally located parking space amenity. A public transport connection to the inner city has been established. The area is provided with a short-distance district heating grid which in turn is supplied by a woodchip-burning facility and a natural gas system. The entire rainwater is infiltrated via a trench - basin system at the edge of the site.
The innovation within this project most of all lies in the design of the planning and construction process. A determining factor in this was the extensive coordination provided by the town planning department throughout, which facilitated the simultaneous execution of all the different sectoral planning processes. Following an initial architecture competition, architects further elaborated the designs jointly with regional skilled trade companies who acted as building contractors. Marketing efforts in the shape of two „project fairs“, where the buildings were introduced to the public, and a survey of potential buyers were aimed at testing the market acceptance enjoyed by the competition designs. The survey results served as a starting point for the urban outline planning and the legally binding land use plan as well as for the distribution of purchase options to interested investors. Legal planning specifications and the open space planning were adjusted to the building types selected in parallel to the developmental and structural planning. The civic engineering development was planned by a team including urban planners, municipal utilities, civic engineering departments, electricity providers, and the site manager and ensured, amongst other things, that approximately 8% of the overall development costs could be saved by providing joint connections supplying entire rows of buildings.

Aims
Source: www.Biberach-Riss.de
- Planning and execution quality and cost optimization via interdisciplinary planning and construction team
- Optimized environment in terms of infrastructure and urban planning
- A product „house“ allowing for resource-protective construction and operation
- Favourably priced buildings for owner-occupiers (purchase prices ranging from 350.000 to 450.000 DM, including basements, parking space, property).
Types of measures
Source: www.Biberach-Riss.de
- Coordination of sectoral planning performed by town planning department
- Two-stage architecture competition, tendering performed jointly with skilled trade companies
- Sale of individual building plots to various investors
- District heating supply via woodchip-burning facility plus gas heating
- Environmentally compatible construction method: predominantly timber construction, southern orientation for solar energy use, low energy standard, surface water retention
- Cost cutting: high degree of prefabrication, job lots of identical components, joint service connections, small plots and a centrally located parking space amenity at the edge of the settlement
Innovations
Source: www.Biberach-Riss.de
The cooperative approach to planning and construction processes and the early involvement of potential owners are exemplary. Particularly notable are the cost reductions achieved by the parallel approach. The intensive coordination of stakeholders working simultaneously is assessed positively and deemed “expandable” by the participants.
