As accredited surveyors and experts we specialise in construction. The majority of our customers consist of courts, public prosecution, public domain and commercial clients. Our competencies include preventive preservation of evidence, expertise on building damage and international real estate valuation. Our general expertise in an array of fields enables us to solve complex and wide-reaching problems.
The GSB assessment will be formalized in a report and, if you wish, an certificate, sticker or construction sign.
Our comprehensive digital, high-resolution preservation of evidence attracted many major customers across Germany, e.g. international trade and construction companies like Axel Springer SE or Deutsche Bank, infrastructure conglomerates like Deutsche Bahn, large and mid tier real estate companies like TLG Immobilien, Deutsche Wohnen, housing associations, public institutions of the federal, state and municipality level, regional constructions companies and private customers.
Our central GSB laboratory provides a quick and high quality analysis of complex damages and deficiencies, including chemical material analysis and microscopic examinations of building fabric.

Why GSB Experts?

Our professional expertises helped in countless cases to avoid expensive and time consuming legal disputes. We operate in Europe, with an increased focus on Germany, where you can find our subsidiaries in Berlin, Erfurt, Leipzig, Weimar and Mannheim.

What are the costs? How much for an expert report?

The costs for a report heavily rely on the individual circumstances. To assess the expert’s fees, we would need the following information: Who is the customer? Where is the object located? What has to be assessed/ surveyed/ probed? Preferably you send us these informations via an e-mail inquiry.
