In construction projects, TABERG Ingenieure GmbH – part of SIERA is regularly involved in soil-related evidence preservation. The objective is to systematically determine, evaluate, and document the condition of land affected by construction activities.
Infrastructure Expansion and Temporary Land Use
Extensive infrastructure projects are currently being implemented. In addition to the main intervention areas, additional temporary construction-related areas are often required on adjacent land.
These include:
- site setup areas
- assembly areas
- storage areas
Although these areas are not part of the main intervention zone, they can still impact soil and ecosystems.
Environmental Considerations in Planning
During planning, efforts should be made to avoid additional impacts on undisturbed natural areas.
If this cannot be avoided, the following aspects are considered:
- soil protection
- species protection
- water protection
The objective is to exclude particularly sensitive areas wherever possible.
Mitigation Measures and Site Condition Assessment
During construction, environmental mitigation measures must be implemented reliably.
A central component is:
- determination
- evaluation
- documentation
of site conditions.
These form the basis for:
- evaluating the effectiveness of mitigation measures
- recommendations for recultivation
- potential interim land use
Timing and Methods of Soil Investigations
Soil parameters are recorded:
- before land use
- after completion
- and, if required, during construction
Methods include:
- visual documentation
- field investigations
- laboratory analyses
Assessment of Soil Physical Parameters
Field investigations allow for the assessment of:
- natural bulk density
- existing impairments (e.g. compaction)
Undisturbed soil samples may be taken and analyzed in laboratories for:
- dry bulk density
- pore space distribution
Assessment of Soil Chemical Parameters
In many cases, soil chemical parameters are also evaluated, including:
- site productivity (e.g. C/N ratio, nutrient availability)
- environmentally relevant pollutants (e.g. heavy metals, hydrocarbons)
Objective: Avoiding Permanent Damage
The findings help to:
- avoid permanent damage
- restore the original site condition appropriately
This ensures that natural soil functions, which are essential for ecological value, are preserved.
