Geotechnical Engineering and Environmental Consulting

Dynamic Earth, LLC provides Geotechnical Engineering and Environmental Consulting services to support the commercial, industrial and residential development processes across the United States of America .

Our technical expertise is amplified by an in depth understanding of the geotechnical and environmental challenges during land development process. Our construction phase consulting services complement the initial geotechnical and environmental studies provide guidance for correctly implemented recommendations. Our industry insight and experience provides conclusive, practical and valuable guidance for evaluating the land development process from purchasing to final construction phase testing and inspection.

Land Development

Dynamic Earth offers resilient design and recommendations related to the geotechnical aspects of a project including foundations, below grade structures, floor slabs, dams, and retaining walls. Our coastal resilience experience includes shoreline protection, erosion stabilization, and seawalls. In our land development process, we utilize our innovative tools, collaborative in-house professional experience and documented case studies to provide consultation to clients, owners, planners, insurers, stakeholders, etc. in relation to designing flood proofing measures to mitigate risk for future storm events and making economically viable decisions for their development projects. Evaluating and discussing the appropriate geotechnical considerations for a development is critical to the constructability, life expectancy, and resiliency of the project.

Dynamic Earth is also accredited by the ANSI National Accreditation Board per the requirements of ISO/IEC 17020:2012 in the field of inspection; Certificate Number AI-2908. We are a licensed New York City Special Inspection Agency; and licensed Special Inspection Agency in the City of Philadelphia. Our personnel also hold NJ DCA Special Inspector Licenses. These certifications enable us to meet your construction projects’ Special Inspection requirements. Dynamic Earth has qualified engineers to complete required Stormwater Pollution Prevention Plan compliance inspections for your construction site.

Our Allen, Texas laboratory has obtained AASHTO accreditation. Our field and laboratory services range from geotechnical site evaluation and construction observation, to inspecting and monitoring the quality of construction materials delivered and installed at your project. Out laboratory capabilities include testing soils, rocks, concrete, aggregates, hot-mix asphalt, stone, masonry and grout.
