Life-cycle sustainability assessment of geotechnical site investigation

The life-cycle impacts of site characterization, an important component most geotechnical engineering projects, are typically not considered in practice nor have they been studied detail. A sustainability assessment (LCSA) was performed to evaluate the environmental and economic several common investigation methods. potential these methods were computed provide normalized metrics for mobilization, drilling, sampling (or) testing, borehole sealing phases life cycle. These impact cost then applied a “typical” 30 m exploration compare different Next, used assess small midsized industry programs investigate how scale with project size. Scenario analyses on consider mobilization choices, grouting materials, influence total impacts. Collectively, this study provides reference framework that allows practitioners parallel when designing scopes work.
