The most cost-effective foundation solutions generally call for a combination of ground improvement techniques suited to the load and the soil conditions. These solutions make it possible to:- support heavy uniform loads (water, oil and gas storage)- support individual loads (pipeline supports, industrial equipment)- support dynamic loads (oscillations, vibrations, seismic loadings)- reduce absolute and differential settlement of structures.- reduce the risk of soil liquefaction This type of project calls for good knowledge of the constraints and specifications of each structure to be treated with a familiarity with the potential technical issues Which could arise during the various stages of the project from concept to handover.
CASE STUDY: Al-ZOUR REFINERY IN KUWAIT
Ground improvement of about 4,000,000 sq. metres of natural soil at the site of a new refinery.
Menard had the mission to improve the bearing capacity and control settlement of a very poor soil made of silt and sabkha.
The Group decided to use dynamic replacement and dynamic compaction. It brought together 20 compaction cranes and 150 people to treat the strategic industrial site. Menard put together a team made up of very experienced employees and young talent familiar with the Middle East to carry out the technically and logistically complex project. The combination made it possible to efficiently start the project and should ensure its success.
