Environmental Rehabilitation – Containment Structure and Remediation- VIC

Senversa designed, and completed third party quality assurance services for the construction of a 170,000m³ capacity engineered structure to contain PFAS impacted materials that were the result of former fire fighter training ground use.

The project involved significant EPA involvement on waste management and water treatment plant approvals with the design subjected to both an independent EPA auditor and EPA international peer review. Senversa are happy to say the containment design was approved substantially unmodified. The design accounted for local geological and hydrogeological conditions and relied upon use of a robust geosynthetic lining and cover system.

During Construction, Senversa adopted stringent safety precautions, demonstrating our commitment to providing a safe work environment for all stakeholders involved. The project team worked closely with the contractor and client to successfully manage design variations to account for final volumes and different material properties.

Due to the heightened community concerns and publicity associated with the site, the rehabilitation timeline for completion within the EPA notices had tight timeframes. Senversa successfully delivered the reporting within the regulatory notice timeframes, preventing additional regulatory notices being issued.

During the post construction defects liability period we have continued our role and monitored key performance metrics to confirm design parameters are being maintained.

The project successfully demonstrated a multidisciplinary team of Senversa’s engineers, scientists, GIS and risk assessors working together to deliver a large project resulting in a significant mass of available PFAS removed from the environment.
