Professionals with decades of worldwide experience

Who are we?

Allnamics is a group of experts in the field of geology, geotechnics and foundation engineering. They can act as consultants or actually perform pile testing and geotechnical monitoring, both onshore as offshore. If you feel we can support you or your organization, please do contact us.


The history of Allnamics goes back to the 1970s when the oil was discovered in the North Sea. When huge structures were built and subsequently placed on the sea bed the need arose to check the foundations. This is when Peter Middendorp and Marcel Bielefeld, both working for TNO Building and Construction Research Institute at the time, laid the foundation of what is now Allnamics.

Allnamics itself was founded in 2011 by 5 experienced engineers in the field of pile testing, geotechnical monitoring and soil mechanics, and this team continues to increase in size as Allnamics expands its operations.

In 2012 a state-of-the-art wireless monitoring system, the PDR, as well as other advanced monitoring equipment were developed. With a detailed knowledge of all types of pile testing techniques, the ever expanding team of highly educated, yet practical experts of Allnamics is ready to support and assist our clients around the world.


Allnamics is working from their world wide offices, in The Netherlands, The Hague and Amsterdam, Singapore, USA and Spain. Allnamics is commercially working together with agents and representatives in many countries in the field of pile tests and geology, geotechnics, soil mechanics and foundation engineering.
