Our Earthworks Projects
Mesa J HV and LV Facilities
Port of Ashburton Sand Bypassing
OSPL G3 Levee Repair
Thunderbird Mineral Sands
Dust Suppressant
Mesa J HV and LV Facilities
NTC was awarded the bulk and detailed earthworks for the HV and LV upgrades at the Rio Tinto Mesa J Iron Ore Mine. The works included:
- Construction of a clean water pond
- Detailed earthworks for all concrete footings
- Bulk earthworks
- Rock Breaking
- Windrow Construction
The works were to be constructed around an active HV workshop which daily had large mine haul trucks moving around the area.
The works were also hampered by a large amount of rock present under the new HV workshop expansion. Large detailed footings were broken out and completed to the best detail possible.
Port of Ashburton Sand Bypassing
NTC was awarded the Sand Bypassing project for the second time to bypass 80,000m3 of sand built up between the Port Breakwater. The works included:
- Winning up sand from a design below the low tide level
- Stockpiling and allowing to dry for 7 days
- Transporting sand 3km past the breakwater
- Spreading to design profile
- Drone surveying of all works
Works required planning around the low tides in order to be able to achieve the maximum amount of bypassed sand in the design which was near the lowest astronomical tide mark. NTC tailored our maximum production shifts around this period in order to make the most of these tides which only happen monthly at best.
OSPL G3 Levee Repair
NTC was awarded the repair works for a failed levee wall at the Onslow Salt Mine. This levee had a subsurface spring affecting the integrity of the salt crystaliser. The works included:
- Winning and Hauling Clay Core Material
- Removal of cemented salt
- Installation of a geocomposite grid layer
- Installation of lined panel drains
- Installation of a cuttoff drain with discharge
- Backfill construction of levee using clay core
A very detailed ITP and signoff process was required for these works as they included an intricate design of geocomposite, and panel drains all feeding into a discharge pipeline.
Thunderbird Mineral Sands
NTC was awarded an earthworks project at the remote Thunderbird project for GR Engineering. This contract was undertaking all the bulk and detailed earthworks including road works for the processing plant at the Kimberly Mineral Sands Thunderbird project. The works included:
- Bulk Earthworks
- Detailed Earthworks
- Pond Construction
- Roadworks
- Stormwater Drainag
Dust Suppressant
NTC was awarded a project through development WA to initially provide dust suppressant to the vacant lots in the Barrarda Estate but also to develop a native seeding plan. The works included:
- Application of Dust Suppressant
- Development of Seeding Program
- Monitoring
- Slashing and Fire Prevention
The initial works consisted of several applications of Gluon a dust suppressant product. After this a seeding plan was developed using natural seeds from the area. Finally, now that all growth has taken off a slashing program is underway to ensure the growth now does not cause fire hazards
