Every contaminated site investigation starts usually with a historical investigation of the location. The subsequent technical exploration is usually conducted by using small calibre drillings. These drillings are necessary in order to take soil, soil gas and water samples which are tested for contaminants.

The following project management comprises all project phases, including the preliminary draft, the tender process, the construction supervision, the final inspection of the remediation measures as well as the monitoring of the restored site afterwards.

We assist our clients by developing remediation concepts and studies of variants and compile all planning documents required for the official approval. We also advice our clients during the consultation process with authorities, e.g. with approval procedures.

We prepare specifications, organize the tender process and make award proposals. We assist our clients during negotiations with contractors and supervise all construction works.

The construction supervision on site and the site management is carried by experts with many years of experience in order to guarantee an efficient and smooth implementation of the remediation and construction projects.

Our services in detail:

• Historical investigations
• Basic investigations, detailed investigations pursuant to the Federal Soil Protection Law (BBodSchG) and Federal Soil Protection and Contaminated Site Regulation (BBodSchV)
• Geological and hydrogeological site investigations
• Groundwater and pollutant transport modelling
• Risk assessment according to § 9 BBodSchG

For complex redevelopments of brownfields, remediation investigations and designs are required according to the soil protection regulations. The feasibility study of different remediation techniques under technical and economical aspects is part of this process.

Due to our comprehensive experience we know about the potential but also about the limits of all remediation techniques used to secure and decontaminate soil, soil gas and groundwater. With this wide range of experience we guarantee to find the optimal solution for your project site.

Our services in detail:

• Remediation investigations according to § 13 BBodSchG
• Remediation planning according to § 13 BBodSchG
• Studies of variants and feasibility studies
• Cost-benefit analysis and cost estimate
