Site Investigation

During our comprehensive site investigation process, we offer a range of services aimed at evaluating soil, rock, and groundwater conditions to provide crucial insights for engineering and construction projects. Our expert team conducts thorough desk studies and preliminary assessments to review existing geological and environmental data, followed by on-site reconnaissance to observe surface features and accessibility. We utilize advanced techniques such as geological mapping, soil sampling, and in-situ testing to assess subsurface conditions accurately. Additionally, our geophysical surveys provide valuable insights into the site's geology and potential hazards. Through soil sampling and testing, we analyze soil properties and conduct laboratory tests to determine characteristics such as grain size distribution, moisture content, and strength parameters. By offering these comprehensive services, we ensure that our clients receive accurate and reliable data to support informed decision-making throughout the project lifecycle.
