To meet the needs of our ever-growing populations and urbanisations, underground spaces are becoming increasingly important. Tunnels are key to providing vital infrastructure that is efficient, future-proofed, and sensitive to the environment.
GHD's tunnels team brings a depth of international experience in underground space design and construction. They work across the project and tunnel lifecycle, developing award-winning solutions from feasibility and planning through to design and construction support.
Whatever your needs, we deliver services to ensure safety, value, efficiency, and reliability for your tunnelling project. We help clients gain maximum outcomes from their projects through proactive investigation and analysis. We conduct constructability reviews, identify potential environmental challenges and develop mitigation, ITIG JCOP compliance and due diligence reviews, and act as an expert witness to support their planning processes.
Our structural engineers are skilled in designing underground spaces, from noise vibration, and air quality modelling to structural design and analysis. We also carry out risk assessments, condition inspections and remediation of existing tunnels, geotechnical assessments, and ground-structure interaction analysis including numerical modelling.
We have worked on a range of industry-leading and award-winning schemes using a range of techniques including cut-and-cover, drill-and-blast, NATM, TBM, pipejacking, HDD, and microtunnelling. Our technical expertise includes designing launch chambers, temporary shafts, manholes and caverns, mechanical and electrical systems, fire life safety, ventilation systems, and commissioning and decommissioning arrangements.
Having delivered road, rail, sewerage, water supply, hydropower, desalination plant, and utility tunnels, we have the expertise and track record to meet your needs. Our end-to-end service includes tender phase and detailed design to project procurement advice, and construction supervision.
It is this fully integrated service and flexibility to fit components around your project needs that sees us held as a leader in the design and engineering of tunnels and underground spaces.
