## Service Relationships

- PSI usually precedes DSI.
- DSI commonly leads into contamination risk assessment, remediation or environmental management planning.
- Groundwater investigation often supports DSI, risk assessment and remediation.
- Environmental management services and EMP/CEMP/OEMP work are commonly used where residual contamination, construction controls or ongoing compliance need active management.
- ESG environmental work is strongest where transactions or governance questions depend on actual contamination, groundwater, approval or management risk.
