Civil Engineer, Ph.D Geotechnics


A civil engineer with more than 30 years of experience in environmental and geotechnical engineering in many countries of Europe, Africa, Middle East and Asia, Jean-Michel Simon has managed environmental and geotechnical engineering projects, such as Environmental Impact Assessments (EIA) for oil and gas facilities and refineries (Angola, Egypt, Nigeria, Yemen), geotechnical investigations for buildings (Indonesia, France, Switzerland, Morocco), pipelines, oil terminals (Tunisia, Cameroon, Angola) and railroads (Morocco), remediation of oil contaminated sites in Ecuador, landfill design in France and Switzerland, environmental auditing for the chemical, mining and manufacturing industries (due diligence audits, risk evaluation of environmental liabilities).
 


Pierre Caloz
Ms. Geology, UNIL
Ms. Hydrogeologist, UNINE


A hydrogeologist with twenty years of experience in geology and hydrogeology, since 1991 Pierre Caloz has been involved in contaminated site investigations and remediations .Many of his projects have been related to the oil industry but also to other industrial clients, such as chemical industries, aluminium, former recycling facilities, sanitary landfills, law offices and banks. With GEOS since 1995, he has conducted numerous environmental site assessments in Europe, the Middle-East and the Americas. He manages hazardous waste site investigation and remediation projects in Switzerland. Prior to moving to the environmental field, he worked for four years as a hydrogeologist in groundwater resources development and technology transfer projects in West Africa.
 


Laurent Cassan
Civil engineer


Laurent Cassan is a civil engineer with 20 years of experience in environmental, geology and civil engineering. With GEOS since 2002, he conducts various civil engineering projects as a project manager in charge of general and technical management, financial controlling and coordination. He also takes part in various engineering geology studies, contaminated site remediation, landfill construction studies and building complexes. Involved in structure, renovation, underground works, engineering structure and civil engineering, he is the assistant of the civil engineering, structure and remediation department manager.

 


Esteban Rosales
Engineering geologist UNIL/EPFL


As an engineering geologist with specialisation in geotechnics and the environment, Esteban Rosales is involved in contaminated sites investigations and remediation projects for industrial, chemical and petrochemical sites. He conducts fieldwork such as soil and rock boring and testing in industrial sites, monitoring well installations, air, soil, soil-gas and groundwater sampling, on-site analyses, aquifer testing and piezometric datalogging. He collects and provides physical and chemical data for risk assessments, modelisation, description of pollution sources and chemical transport mechanisms. He is involved in environmental assessments and compliance audits for mergers and acquisitions. He does geological mapping, cross-sections and 3-D diagrams for surface and underground works.

 

Cédric Ménoret
Ph.D Biologist

Cédric Ménoret is a biologist specializing in the environment, water treatment and waste management. His Ph.D thesis focused on the biological treatment of wastewater issued from the agro-alimentary industry. He has a good knowledge of waste disposal methods, waste storage and recycling and also ecotoxicology. With GEOS, he is involved in field data acquisition during site characterization and monitoring, data treatment, reporting and quality control of laboratory data. He is in charge of environmental audits for property transfers, compliance audits and of a regulatory watch for Switzerland. As a computer sciences specialist (INSA), he designs, develops and manages databases and the geographic information system.

 

Alfonso Villegas
Civil and environmental engineer

Alfonso Villegas has more than 25 years of experience, firstly as a civil engineer specialising in geotechnical engineering, and also as an independent consultant on geotechnical and environmental projects. He was responsible for the coordination of the first Geneva Waste Management Concept and participated in the development of the current Waste Management Plan for the Canton of Geneva. He is also responsible for Geneva’s industrial waste inventory and statistics including information acquisition, data base development and annual reports. Alfonso Villegas has been involved with contaminated sites since the beginning of the 1980s. Recently, he has carried out several environmental audits of industrial sites in Switzerland.
