Frequently Asked Questions
1. What methods are used in tunnel construction?
Tunnel construction methods include TBM tunnelling, drill plus blast, cut and cover, plus micro tunnelling where suitable. In NSW, the method depends on ground conditions, tunnel depth, surface constraints, plus the required tunnel function. SCE Corp helps align methodology, staging, plus plant selection to the agreed scope, using ISO certified management systems to support consistent delivery controls.
2. How is the route determined for a tunnel project?
A tunnel route is determined through design plus investigation. This typically includes geotechnical investigation, survey, identification of existing underground services, constructability assessment, plus impact review. In NSW, requirements vary by corridor constraints plus project approvals, with responsibilities defined by the contract plus relevant authorities. SCE Corp can support constructability input to reduce delivery risk within the agreed scope.
3. What machinery is required for tunnel construction?
Tunnel construction machinery depends on tunnel diameter, depth, method, plus ground conditions. It can include a TBM or excavation plant, drilling rigs, shotcrete equipment, lining installation systems, ventilation plant, plus spoil handling and haulage equipment. Projects may also use monitoring instruments for settlement plus movement. SCE Corp mobilises equipment to match the selected methodology plus NSW site constraints where required by the contract.
4. What safety measures are implemented during tunnel construction?
Tunnel construction safety typically includes controlled access, ventilation plus air quality management, ground support controls, ground movement monitoring, communications, plus emergency response planning. PPE requirements apply across the work zone. The exact controls depend on the project risk assessment plus the approved work methodology. SCE Corp applies ISO certified systems to support repeatable planning, inspections, plus documented controls.
5. How long does a tunnel construction project take?
Tunnel construction timelines vary based on tunnel length, diameter, ground conditions, excavation rate, lining requirements, spoil logistics, plus interfaces with other works. In NSW, access constraints plus staging requirements can significantly affect duration. SCE Corp can provide a realistic program once scope, constraints, plus the delivery method are confirmed for the project.
6. What is a bored tunnel and how does it differ from other tunnels?
A bored tunnel is excavated underground, commonly using a TBM, which can reduce surface disruption compared with cut and cover. Cut and cover uses open excavation then reinstatement, often suitable for shallow alignments when access is available. Drill plus blast may be used in suitable rock conditions where the methodology allows. Selection depends on depth, environment, plus ground conditions.
7. How is groundwater managed during tunnel excavation?
Groundwater is managed using a mix of dewatering, grouting, waterproofing, plus drainage systems, supported by monitoring. The approach depends on water table level, permeability, soil or rock type, plus tunnel design. Early planning is important because water ingress affects stability, productivity, plus safety. SCE Corp coordinates groundwater controls within the tunnel scope where required by the contract.
8. What is included in tunnel construction scope for civil projects in NSW?
Tunnel construction scope can include excavation or boring, ground support, lining installation, drainage provisions, plus spoil handling logistics where specified. Interfaces with Underground Works NSW can include access shafts, service protection, plus ground improvement if included in the contract scope. Civil Engineering NSW support can cover staging, constructability, plus coordination across packages. SCE Corp confirms inclusions plus exclusions before work starts.
