  • CPTs Hillegersberg, Rotterdam

    GSNED BV has accepted the assignment from Gebr. van ‘t Hek bv from Zuidoostbeemster to perform additional geotechnical soil surveys for the project “Looslaan 9 in Hillegersberg”.

    For project C.N.A. At Looslaan 9 in Hillegersberg we performed 12 CPTs. 3 CPTs with measurement of cone resistance and local adhesive. These CPTs had an average depth of around 25.40 meters minus ground level.

    We have also carried out 9 water CPTs. These were situated next to the plot where we carried out the land surveys. These CPTs had an average depth of 27.8 meters minus the water bottom.

    In addition to the above CPT activities, we have carried out sonar measurements from the water. Of course everything with our own equipment so that a fast processing time is guaranteed.

  • Marina Goes

    GSNED BV has accepted the assignment from the Municipality of Goes to perform geotechnical soil surveys for the “Marina Goes” project. For this project we performed 13 CPTs from the water. With the help of pontoons, which were steered by our push boat GSNED 18, 13 CPTs were carried out at the project locations with the measurement of cone resistance and local adhesive. The average depth was approximately 10 meters below the water bottom.

  • Cycling underpass Sint-Lievenpoort in Ghent

    GSNED has accepted the assignment from Artes Depret nv from Zeebrugge to carry out additional geotechnical soil investigation for the project "Cycling underpass Sint-Lievenpoort (R40 Sint-Lievenslaan) in Ghent". For this, 2 verification CPTs were carried out with the measurement of cone resistance and local adhesive. These inspections had to be carried out on the water under an existing bridge, which made the movement space extra tight and the challenge extra high. We used pontoons with a crawler crane and mounted our 20-ton CPT platform on it. Through casing tubes, which we placed next to the piles, we could be sure that the CPT rods would not bend.

  • Hollandse IJsselkering

    The storm surge barrier Hollandse IJssel, Hollandsche IJsselkering or Algera barrier is a weir in the Hollandse IJssel, in the Dutch province of South Holland, which serves to prevent too much water from entering the country in the event of extremely high tide. It is the oldest work of art of the Delta Works. Rijkswaterstaat has maintenance work carried out which will be carried out by Aannemingsbedrijf de Klerk bv. The work mainly consists of implementing improvement measures on the sheet piles of the Hollandsche IJsselkering complex. Part of this includes the preparation of a geotechnical survey report.

  • 70 meter deep CPT's for Sluishuis Amsterdam

    Sluishuis will become THE new architectural landmark of Amsterdam and a jewel for the IJburg district. Sluishuis will be situated near Steigereiland-Noord and is located directly in the IJ, thereby doing justice to the beauty of the surrounding water. The Sluishuis consists of approximately 440 apartments, parking spaces, commercial spaces and mooring places for houseboats.

  • Major Maintenance Waterways

    The Netherlands is the European junction for transport by water. The Dutch waterways are therefore one of the busiest in the world. It is important that we maintain and further develop this powerful position. Well-maintained waterways are essential for this. That is why Rijkswaterstaat is carrying out maintenance work within the framework of the Major Maintenance Waterways (Groot Onderhoud Vaarwegen or GOVa) project. At 16 locations within the Rijkswaterstaat management areas South Netherlands and Sea & Delta, various risks are foreseen for inhibition and guidance work as a result of overdue maintenance.

    The aim of the 'GOVa 7c' project is to ensure a safe, available and reliable main waterway network, by implementing the necessary measures as quickly as possible, within the preconditions and budget, for the overdue maintenance of the fender and guidance works. to address the objectives of Rijkswaterstaat in the field of a sustainable living environment and circular economy.
    Rijkswaterstaat has awarded the contract to Witteveen + Bos.
