SGDA mbH engineering services for brownfield sites and abandoned industrial sites from exploration to redevelopment

The term "historical research" describes the collection of data, except from samples, for a restricted spatial area.
The purpose of historical research of areas suspected to be brownfield is by detailed research to define all types of use of the site and its surroundings and assessing their effects on different ecological media (soil, soil atmosphere, air, surface water, etc.) as a function of the site conditions and/or describe and assess subjects of protection (man and groundwater).

Informing exploration and detailed examination follow the historical research of a brownfield-suspected area or abandoned site requiring technical activities. According to BBodSchG , experts and examination bodies which carry out such work must have the required professional qualification and reliability and the necessary technical equipment.

The purpose of informing exploration is to confirm or refute the suspicion that a certain property may be an abandoned industrial site. The type, concentration and distribution of contaminating substances in soil, soil atmosphere and water are measured at certain points and the results referenced to standard values of contaminants and specific correlations.

If the suspicion of brownfield site is confirmed by the informing exploration, the detailed examination adds knowledge to permit a final answer as to the risks (type and scope) emanating from the examined site.

The purpose of the redevelopment investigation is the case-based definition of the technical and financial suitability, legal possibility and proportionality of a redevelopment version for the permanent aversion of risks, substantial disadvantages or the level of nuisance for individuals or the general public under the aspect of the use of the site as permitted by planning right. The result of the redevelopment investigation is the redevelopment concept which defines the redevelopment targets, considers the inputs by the parties affected and involved and the completion of all redevelopment work, including their monitoring. The redevelopment concept is the basis fort he development of the redevelopment plan.

On the basis of the optimal redevelopment scenarios defined for the different redevelopment zones, redevelopment planning comprises the translation of the projects in a plan with the stages design planning, approval planning and execution planning of each redevelopment zone. 

Declaring the redevelopment plan as binding

Performing the redevelopment activities declared to be binding.

Provision of professional redevelopment activities: Independent competent professional assistance must be available for all activities; the outside expert also prepares the final redevelopment report.

The report contains a summary of all activities undertaken for the redevelopment of the site such as calculations, description of the redevelopment areas, sampling areas and analytical results, measures, etc. and a final assessment of the redevelopment project.
