Our involvement
- Geotechnical site investigation for new bridge design foundations and pavement widening
- Contamination assessment
- Groundwater monitoring and sampling
Project challenges
Busy intersection required night working with additional program constraints due to noise mitigation. This imposed limit of 2 nights per week working permission.
Bridge foundation boreholes required Sydney Metro approval due to encroachment into underground tunnels first reserve.
Our solutions
Due to tight program constraints, JKG recommended use of Dry-Vac technique that allowed simultaneous clearing of buried services and ability to collect subgrade soil samples for subsequent CBR index testing. This improved overall production rates per night shift.
Bridge foundation boreholes required strict control of borehole termination depths.
