Djorhia Nijssen-Treskes
- Department: Management
Djorhia Nijssen-Treskes is a self-named BIM nerd. But you can leave out the BIM as well. You might run into her at a comic con dressed as a Starfleet officer. Who knows? Everybody calls her DJ, which has nothing to do with who makes the playlists in the office. Even though one of her cats is named AutoCAD, she is all about that BIM!
During her mechanical engineering studies, she discovered her love for mechanical installations specific for buildings. At her first job she quickly combined her love for mechanics with her other interests: data, process, and efficiency. Ergo: BIM! She had the opportunity to work at some prominent companies, which gave her the ability to grow, cooperate with and learn from nice people and work on beautiful and challenging projects.
At DIBS42 she is a Co-founder and manages the Dutch team. Her focus is on the people behind the project. A happy team and a happy client result in a happy DIBS42. Besides that, she focuses on process, data, and sustainability, trying to make the world a more beautiful place.


Theo Kaak
- Department: Engineering
Theo Kaak is BimBaas at DIBS42 with an electrical background and over 15 years of experience. He calls himself a practical Bimmer, is data–driven and is always on a quest for a perfectly set-up and neat model. For Theo, a project can’t be big enough, but he also places his love in the smaller ones. He began his working career at Kropman as a draftsman. There he was attracted by the software side and at Cadac, he was an intermediary with the Autodesk-Support team. His passion for building brought him back into the game of MEP-engineering and he worked his way up to BIM-coordinator at BAM and is now working for DIBS42.
At home, he enjoys being with his wife and kids and in his free time, he enjoys playing on his Xbox. He loves playing strategy- management games and shooters. In online First person-shooters, he has an infamous k/d ratio, but he is always there to support others. He has a love for the Dune novels and uses a quote from it with every project he works on: “A beginning is the time for taking the most delicate care that the balances are correct”.
Vesna Mandić
- Department: Engineering
Vesna Mandić is BIM electrical engineer at DIBS42. She claims that she can determine flickering lights as electrical problems or demons, with 100% accuracy. Other than making unnecessary bets, she is always up to minimize even the slightest mistakes or visual ambiguities on the projects.
