ON THE APPLICATION OF DUCTS AND CULVERTS
Often the long-term benefits of ducts and culverts on different economic, environmental and temporal levels can be identified in a general way but are then not taken into account in strategic planning. For this reason, the concept of a checklist has been developed to answer the following question:
Should the use of an underground line duct be considered for the planned construction project as an alternative to the conventional individual laying of supply and disposal lines?
The checklist is intended to enable stakeholders to make an initial assessment of whether a line duct or line culvert should be considered as a possible alternative.
The checklist consists of 13 questions that can be answered with “Yes”, “No” or “Not enough information is available” (see figure below). The following relevant categories are covered:
- Path bundling & interchange flexibility,
- Resilience and Sustainability,
- Legal options, and Restrictions,
- Knowledge of line ducts,
- Overall life cycle view and stakeholders.
The result is a recommendation for action based on the answers.
The goal is to have a “tool” in the future that can dissolve the niche character of the duct and create the conditions for gradual market penetration. In this way, ducts could also have a positive effect on sustainable construction in times of economic weakness and be included in demand planning.
