The TDD that secures your transaction

Whether for acquisitions, disposals, forward deals, or repositioning projects – we identify technical and sustainability risks, analyze their impact, and provide practical recommendations and opportunities for value enhancement.

Your Benefits

What a thorough TDD means for your deal

Fast, Flexible & Reliable

Fast response times for a secure transaction process: proposals and final reports are typically delivered within two weeks of the site inspection. We flexibly integrate additional requirements into our reports without delay.

All Disciplines from a Single Source

Our team covers structural engineering, MEP, fire safety, environmental issues, and building law. We integrate ESG aspects directly into our assessment to reduce interfaces and increase efficiency throughout the transaction process.
