In 2023, we performed a focused soil investigation at an International Airport Terminal as part of a renovations project. This 1,900 SF project was conducted entirely outdoors in full compliance with federal and state environmental standards. The goal was clear: characterize soil, assess worker exposure risks, and support uninterrupted construction progress.

To achieve this, we developed a tailored sampling strategy and conducted hazard assessments to evaluate both cancer and non-cancer exposure pathways, along with soil waste classification criteria. During testing, our team detected elevated concentrations of arsenic, cobalt, and chromium. However, after comparing results against site-specific thresholds and local background levels, we confirmed the soils complied with all regulatory requirements. In addition, close collaboration with airport and construction authorities kept investigation activities aligned with renovation schedules, minimizing disruption and ensuring operational continuity.

As a result, efficient soil sampling, real-time field analysis, and concise reporting supported rapid decision-making on site. By verifying the soils as non-hazardous, we enabled safe onsite reuse and avoided costly offsite disposal. This approach also allowed us to implement a customized health and safety plan to protect workers during excavation. Consequently, the project not only met compliance goals but also delivered strong value, with an expected ROI of 100–200% through cost avoidance and efficient execution.

Overall, the project highlighted our ability to deliver practical, innovative solutions for complex environmental challenges in active construction environments. Through strategic planning, adaptive field techniques, and proactive stakeholder engagement, we ensured the renovations advanced safely, efficiently, and sustainably.
