Acciona Samsung Bouygues Joint Venture
PROJECT DELIVERABLES /
• Construction Management
• Remediation & Validation
• Site Assessment
• Specific Excavation
Epic was engaged by Acciona Samsung Bouygues Joint Venture (ASBJV) to provide environmental consulting services across a wide range of fields for the project. The M4-M5 Link Tunnels are being constructed to connect the new M4 at Haberfield and the new M5 at St Peters. Each tunnel is approximately 7.5 kilometres long and will be able to accommodate up to four lanes of traffic in each direction.
Epic completed the following for the project:
Phase 1 Environmental Site Assessment
Development and implementation of an SAQP for intrusive investigations
Development of onsite training and user manuals for the ongoing landfill gas monitoring
Development of task specific excavation management plans to allow works to continue in known areas of landfill gas
Hazardous ground gas risk assessment to inform the design and assess the risks associated with the construction of the tunnel through the former landfill site
Pre-demolition survey, working in tandem with the hazardous materials consultant
Epic worked closely with the ASBJV Environmental Team and the appointed NSW EPA accredited Site Auditor throughout the engagement to ensure the project milestones were met on time and on budget. All key deliverables were reviewed and approved by the Site Auditor.
