Relocation of UNESCO defense monuments

(Dutch Only!)To relocate the bunkers from the nominated UNESCO world heritage locations "de Hollande Waterlijn" in Nieuwegein (the Netherlands) the complete bunkers have to be lifted from their piles.

Building sway due to high wind speeds

Measure & analyse building movements caused by wind

The 2nd generation sensors enable us to measure, visualize and quantify the movements of high-rise buildings, sky-scrapers and chimneys due to high wind speeds.

Open Seismic Sensor Grid

(Dutch only!) The OSSG (www. ossgrid.nl) is a open-data platform for induced seismic activities.


System evaluation by Floodcontrol

Trailer providing an impression of macro stability tests 2009 in the north of Holland. Test where very successful and this system was immediately relocated to a real life crises situation.

Sensor placement

(Dutch only!) The movie shows what factors to take into account when picking sensor locations for a project. This is done by the 'de Waag' project as example. The video is dutch, but the images speak for them selves. It might be worth giving it a try..

Jacking UNESCO "Wevershuisjes"

Due to a breach in a wall of a subway station under construction the famous "wevershuisjes" subsided towards a single corner as much as 24cm within a few seconds, leading to near collapse. We've monitored the reconstructive jacking.

Detecting shifting sand layers below tarmac

During a dike macro stability project we needed te know how much the tarmac contributed to the deformation of the dike near the waterline.

Crack detector

One of our special solutions. We needed to detect wether two completely separated parts of a building where moving relative to each other within a hollow surface. Therefore we designed and build this custom crack detector.

De Waag First Months

Prior to reconstructive lifting we monitored the normal daily behavior of the UNESCO world heritage building "de Waag" in Amsterdam. The film shows the 3D studie in our tool StabiFrame. Prior, due and post reconstruction we monitored it's stability.


Our first major UNESCO assignment

Our first video!.. it shows some of our activities in 2008-2010. Our first major assignment, the reconstructive jacking of UNESCO world heritage in Amsterdam.
