Oliver Bertram – Expert Witness

a

Experience and Precision

Since 2008, I have been a leading specialist in designing, converting, and refurbishing office spaces—successfully managing projects of all sizes, both nationally and internationally.

My range of services includes expert reports in both private and judicial contexts, due diligence reviews, securing of evidence, determination of causes of damage, support in construction projects, and assistance in remedying defects and damages.

As an expert witness, I deliver objective, neutral, and technically robust assessments and precise evaluations of complex situations. Especially in cases of disagreements or disputes between contracting parties, independent, professionally competent advice and reliable reporting are crucial.

In complex cases in the private sector, I adopt a pragmatic, results-oriented approach.. Standard solutions are often no longer applicable – yet a viable solution must still be found. This is where I focus my efforts to achieve the best possible outcome under the given conditions.

Since 2021, I have been Managing Partner of teamgnesda, an interdisciplinary company for architecture and business consulting. Our expertise goes beyond traditional office fit-outs and also covers projects in the hospitality and residential sectors.

“Nowhere are the aspects of construction as closely interconnected as in interior fit-outs. This is where the true value of a property emerges: function and use are manifested in space. Only flawless functionality enables the full realization of a property’s potential.”
