Edwards Airforce Base Phase 2 Site 3 Main Base Inactive Landfill Closure

HAI provided construction quality assurance (CQA) services for the landfill closure for Phase 2, Site 3 Main Inactive Landfill located at Edwards Airforce Base. We provide comprehensive geotechnical observation and testing services, including subgrade inspection, foundation layer compaction, and evapotranspiration (ET) cover placement. Our team conducted rigorous field density tests and laboratory analyses to verify that materials meet specified compaction and moisture content requirements. We also oversaw the construction of stormwater diversion berms and other critical infrastructure components. Our detailed daily reports and final geotechnical summaries ensured transparency and accountability throughout the project lifecycle.
