In order to facilitate the design work, some additional geotechnical investigation was proposed.

PMI Marine & Construction Services Ltd (PMI) was awarded the Geotechnical Site Investigation Works at the New Liberty Gold Mine located approximately 110km from Monrovia in Liberia.

The Scope of Work included:

  • 7 No CPTu tests up to approximately 20m
  • Seismic testing
  • Pore pressure dissipation testing

PMI Resources on Site:

  • 200kN truck mounted CPTu rig.

Contract Execution

The PMI equipment was mobilized over land from the base in Ghana to the mining site in Liberia.

The CPTu testing was done without any delays upon arrival on site.

The results of each test were provided to the Client’s representative on a daily basis and allowed for a quick analysis by the client on relocation of the next test position and even increased test locations during the execution of the project.

The Scope of Work was executed on time and to the required standards of the Client.

A final factual report was presented to Client’s satisfaction.
