Often, land remains unused for decades despite an attractive location and good infrastructural connections. In order to give the investor of such a site planning and cost certainty and to enable a sustainable and economic processing of the site, we offer you comprehensive services in the area of site redevelopment or site recycling.

Land development - our core competence

We are also able to take on such complex projects as the responsible general contractor - benefit from synergies and minimise schedule and cost risks.

"The properties designated as contaminated military sites are old sites and old dumps on which, in particular, armament-specific substances (for example, explosives, incendiary and smoke substances, chemical warfare agents, production residues) were developed, tested, manufactured, processed, stored or destroyed."

"Military contaminated sites are old sites and old deposits that are assigned to direct military operations after the Second World War." (according to UBA - Federal Environment Agency).

Many plots of land remain unused despite their prime location because impairment is suspected due to the history of military use and military-specific pollutants. from historical reconstruction to the implementation of conversion projects, we offer our clients comprehensive services. The linking of different disciplines leads to the successful handling of complex issues in the revitalisation of areas formerly used for military purposes.

Requirements such as the permanent protection of groundwater and the biosphere make site selection and landfill planning more difficult. Old landfills, on the other hand, are often no longer state of the art. If they are leaking, safety measures and sometimes also emission monitoring must be carried out.

Landfill construction: We know the requirements - you get the solutions

We are there for you for all challenges in landfill construction and landfill rehabilitation. With landfill planning, landfill sealing and landfill remediation as part of waste management, safety and aftercare concepts.

According to DIN E 1997-1, a subsoil investigation must be carried out for every building as the basis for structural planning and the geotechnical report must be prepared according to DIN 4020. The soil-mechanical properties of the subsoil determined in this way form the basis for e.g. the verification of foundation stability, the forecast of settlements, the planning of building waterproofing, the possibility of rainwater infiltration, the durability of traffic routes, or the requirement of excavation securing. Our geotechnical engineering department examines the subsoil according to engineering geological aspects and the requirements of DIN EN 1997-2 and advises, plans and optimises the design of the geotechnical trades according to constructional, environmental and economic aspects.

The diverse procedures of special civil engineering offer a suitable technical solution for the implementation of planning goals for almost every situation. The wide range of specialist foundation engineering techniques offers a suitable technical solution for implementing planning objectives in almost any situation where the inherent strength of the ground is insufficient for the introduction of building loads or the construction of steep slopes, where existing structures have to be secured or where groundwater has to be kept out. Ground improvement, pile foundations, retaining walls, underpinning and watertight excavations are the most common applications of foundation engineering. If groundwater or contaminated soils are interfered with in the process, approvals from the environmental agency are required in addition to the static and economic aspects.

Our geotechnical engineering department plans, calculates and monitors geotechnical constructions of all kinds in all service phases of the HOAI and carries out the necessary approval procedures.

The Federal Immission Control Act (BImSchG) stipulates that the construction and operation of installations that can typically cause harmful effects on the environment (see § 4 para. 1 sentence 1 BImSchG) require immission control approval. The types of installations concerned are listed in the Ordinance on Installations Requiring a Permit (4th BImSchV).


Directive 2010/75/EU on industrial emissions: Baseline report


Since May 2013, these industrial sectors have been obliged to submit an initial status report to the authorities before commissioning new plants. For old plants, transitional arrangements apply until July 2015.
The AZB is intended to document the condition of the soil and groundwater with regard to the so-called "relevant hazardous substances" used on the plant site. It serves as a standard of comparison and as evidence for the obligation to return the substances in the event of decommissioning of the facility.
The CSA provides information on the use history of the facility site, presents the environmental framework conditions and assesses existing or newly collected soil and groundwater data.

We support you in all matters relating to the preparation of an AZB:
  • AZB - Preliminary examination
  • Authority management
  • Assessment of the relevant hazardous substances
  • Historical research
  • Preparation of investigation and monitoring concepts
  • Carrying out soil and groundwater investigations
  • Assessment of the baseline condition
  • Documentation and reporting
Rare earths and metals are playing an increasingly important role in global economic and product development. Fossil energy sources, such as oil and natural gas, will also not be superfluous in the coming decades. We support companies and institutions worldwide in the exploration of deposits and their sustainable management. This includes the use of innovative geochemical surface exploration in the prospecting of deep reservoirs for crude oil and natural gas. In wildcat-survey investigations, we use a microbiological field method that combines geochemical and microbiological investigations in addition to geophysics to draw conclusions about the cave-in of the reservoir site. We have achieved an extremely positive hit rate in several international assignments. In addition, we organise and plan the location and investigation of deposits of rare earths and metals. In conjunction with advice on the sustainable and environmentally sound management of mining areas as well as recultivation, we offer our clients comprehensive services in this sector.

Occupational safety management on construction sites and when handling hazardous substances is an important part of occupational safety in contaminated areas. We draw up work and safety plans for you and take over the coordination on contaminated sites. This includes planning, instruction, acceptance and ongoing monitoring of activities in contaminated areas.
Our trained safety and health protection coordinators (RAB 30) take over the cross-trade safety coordination on construction sites on the client's order. In the planning phase, we take over the preparation of the preliminary notice, the safety and health plan and the documentation according to BauStellV. In the execution phase, our SiGeKo coordinates the safety and health protection-relevant interactions of the various works on the construction site.
