Environmental Site Assessment (ESA) - Environmental risks during business operation
The economic potential of a site is essentially dependent on the condition of the subsoil. WESSLING ensures clarity in the topic of site development, from the exploration of construction ground, contaminated sites to advice on land recycling.
The term site is understood and defined differently by every person: the farmer means his cultivated area, a company its production and operating area, the forester his forest, the mayor the residential and industrial area available to the citizens and entrepreneurs of his town, families their living space and children their play areas. What they all have in common is that they are not available in unlimited quantities.

Construction ground
Construction ground
The sufficient load-bearing capability of ground and soil is the prerequisite for the technically flawless execution of earthworks and civil engineering works and for the sustainably perfect use of the construction. It is therefore necessary to check the technical properties of the construction ground prior to construction activities.
To achieve this, WESSLING carries out geotechnical field investigations to determine the soil stratification and its bulk density. The
- soil mechanical and
- soil physical parameters as well as
- geotechnical calculations
derived from this are used to provide a foundation recommendation coordinated to the construction measure, taking economic aspects into consideration.
We also undertake construction supervision tasks: we guide your site to construction maturity on the basis of existing expert reports and/or foundation recommendations. WESSLING carries out the corresponding geotechnical investigations to ensure that recommended earthworks and construction ground improvements have been carried out professionally by commissioned construction companies.

Contaminated sites
Contaminated sites
WESSLING has decades of experience in the exploration, evaluation and remediation of contaminated sites. A step-by-step procedure, in which the effort and thus the costs are kept as low as possible, has proven suitable in this case.
In the context of the use and the relevant resources, our engineers and life scientists will identify for you whether soil and groundwater remediation measures as per BBodSchG/Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV) are required. It is entirely possible that there is no need for action for the individual project, a safeguarding concept is sufficient and thus, that no intervention into the soil is necessary under certain circumstances.
Our experts are experienced in innovative remediation methods such as microbiological in-situ remediation, ISCO and Enhanced Natural Attenuation/Natural Attenuation. They are familiar with all damage arising, for example, from PAH, BTEX, VHH, PFT/PFC, PCB, HC, heavy metals, cyanides and chromium. We are independent of the supply interests of the remediation companies in this case.
Our contaminated site assessment, soil and groundwater remediation services:
- Historical researches and multi-temporal aerial photo evaluations
- Orienting investigations
- Risk assessments
- Detailed and remediation investigations
- Remediation concepts
- Feasibility studies
- Creation of remediation plans as per Section 13 of the Federal Soil Protection Act (BBodSchG)
- Remediation planning
- Invitations to tender and contract awards
- Remediation and monitoring
- Construction management and documentation
- Occupational safety (health and safety coordination, DGUV 101-004)
- Check and re-evaluation of ongoing soil and groundwater remediation measures
Creation of expert reports/statements by publicly appointed and sworn experts recognised according to Section 18 BBodSchG
Our services for your industry
WESSLING provides individual service packages that are tailored to the needs of your company.
Our tasks for sustainable site development
WESSLING supports you in site development with consulting and planning services pertaining to construction ground, contaminated sites, land recycling, soil and groundwater remediation from a single source. We create the basis for the successful implementation of your project through in-depth technical evaluations of the construction ground, old buildings and contaminated sites. We can carry out economic feasibility studies for various usage scenarios even during the early phase of the project.
Our engineers offer extensive experience from major projects across all project phases: from historical research, exploration, design, implementation and approval planning, tendering and contract award to construction management, expert support and supervision as well as documentation. So you receive cost certainty as well as precise scheduling and deadline monitoring.
