Intro to Vac-Ex Equipment

• Vac-Ex Ltd started producing Vac-Ex units in 2008.

• Vac-Ex Ltd are currently in collaboration with Scottish Water and Thames Water in UK.

• Vac-Ex Australia are currently based out of Brisbane since April 2019.

• Allstar Infrastructure purchased the first machines from Vac-Ex Australia to service the Brisbane market in 2019.

• Allstar have a current stock of five (5) Vac-Ex Vacuum Units including both the T-Vac and Air-Vac models.

The Air-Vac & T-Vac Models• Compact towable vacuum excavator for

safe excavation using air around buried utilities in restricted access areas.

• Dry or Wet material excavation.

• Track Mounted.

• Remote Control Operated.

• Hydraulics to power air tools such as jackhammers or saws.

• Kubota 3 cylinder 18.5kW diesel engine.

• 90dB noise level at 1m distance.

• 0.2m3 & 1m3 spoil storage capacity.

• 1650kg or 2200kg on a trailer.

• Tipping sensor (self levelling bin).

Other Water Industry Applications Utilizing Vac-Ex Equipment

• Expose/Pothole live buried services prior to mechanical excavation.

• Expose water leaks for repair.

• Constructing or transferring property service connections.

• Slit trenching for new property connections.

• Cleaning out valve and hydrant pits.

• New water metering installs and repairs.

• Exposing valve and hydrant replacements.

• Servicing and maintenance of a range of pit types.

CASE STUDIES

• Gold Coast City Council: Valve & Hydrant Replacement Program

• Fulton Hogan – QUU Sewerage Treatment Plant Upgrade

• CPB – Queensland Rail Cross River Rail Project

CASE STUDY

Client: Gold Coast City Council

Project: Valve & Hydrant Replacement Program

Scope: Positive Service Location

CASE STUDY

Client: Gold Coast City Council

Project: Valve & Hydrant Replacement Program

Scope: Expose Valve & Hydrants / Positive Service Location

Challenges:

• Working within Pedestrian & Traffic Zones.

• Risk of spraying slurry on parked vehicles / pedestrians with hydro lance.

• Working around live assets.

• Production line included 3 crews: Excavation, Connection & Reinstatement.

• Water & Slurry Disposal Fees.

CASE STUDY

Client: Gold Coast City Council

Project: Valve & Hydrant Replacement Program

Scope: Expose Valve & Hydrants / Positive Service Location

Value Added:• No requirement for traffic control resulting in less

disruption to the local community and homeowners.

• Dry excavation for employees to work in.

• Dust is mitigated in dry areas by utilising a debris skirt.

• No risk of spraying slurry.

• Open excavations backfilled immediately after valve/FH connection complete.

• No Water Fees

• No slurry – No Disposal Fees

• No down time for disposal of excavated material off-site

• No requirement to import backfill material.

• Easily transported and used by civil crews as required.

• Minimised 2 crews along production line.

CASE STUDY

Client/s: Fulton Hogan

Project: QUU Sewerage Plant Upgrades

Scope: Utility Mapping & Positive Service Location

CASE STUDY

Client/s: Fulton Hogan – QUU Sewerage Treatment Plant

Project: Sewerage Plant Upgrades

Scope: Positive Service Location

Challenges:

• Working within Brownfields Area (above & below infrastructure)

• Tight access areas.

• Contaminated spoil. No disposal off site allowed.

• Out-dated existing buried electrical cables

CASE STUDY

Client/s: Fulton Hogan – QUU Sewerage Treatment Plant

Project: Sewerage Plant Upgrades

Scope: Positive Service Location

Value Added

• Excavated material reused as backfill & cross contamination of material avoided.

• No requirement to build turkeys nests for drying out of slurry material associated with hydro excavation.

• Compact tracked machine was perfect for tight areas that trucks could not access

• Minimised risk of water ingress and cable damage when exposing electrical cable joints.

• No damage to above or below ground infrastructure.

CASE STUDY

Client: CPB

Project: Queensland Rail Cross River Rail

Scope: Positive Service Location

CASE STUDY

Client: Queensland Rail

Project: Cross River Rail

Scope: Positive Service Location

Challenges:

• Limited access along live rail corridor.

• Existing above ground rail assets (rail, rail bond lines) along narrow access.

• Only means for a truck to reach work zones was from outside of the rail corridor in most areas.

• Third party permits and approvals required to allow for large plant and truck access.

• Cost of replacing Ballast.

CASE STUDY

Client: Queensland Rail

Project: Cross River Rail

Scope: Positive Service Location

Value Added:

• No Council Permits Required.

• No Pedestrian Pathway Closures.

• No Train Station Car Park Closure.

• No Need for Traffic or Pedestrian Management.

• No Importation of Foreign Fill.

• Open Excavations Backfilled Immediately After Assets

• Positively Identified and As-Con Info Recorded.

• No Water Disposal Fees.

• No Damage to Existing Above or Below Ground Assets.

• No requirement for additional pothole backfill crew, resulting in less plant and personnel required to work in a live rail corridor.

Potholing Detailed Photos Images

Utility Mapping Services:

• Request DBYD

• Service Location and / or CCTV

• Non-Destructive Excavation utilizing Vac-Ex

Equipment

• Provide Photo Records of Exposed Assets including

Direction, Coordinates, Asset Details, Type etc.

• Vacuum Excavation crew/s will have appropriate

tools and skills to cut concrete / asphalt and

reinstate when required.

• Our future goal is to provide BIM and GIS data in

Augmented Reality.

Client Feedback:

“The Allstar crew certainty walked the walk with there small tracked vacuum unit. They got their machine into areas within a brownfields environment where our team didn’t think was possible. The advantages in utilising this equipment really is a no brainer”

Gerard McGuigan - Project Manager – Fulton Hogan (speaking about Vac-Ex equipment)

“Thank you Allstar Infrastructure for providing our project with a high quality, reliable and professional service. You always responded to our day to day challenges with providing the right solutions. I look forward to working with your team in the future”

Construction Manager – Monadelphous

“Vac-Ex equipment certainly proved its advantages with savings on water and disposals fees alone. There are a number of environmental challenges we face on these RAAF base projects however this equipment has mitigated the concern with utilisng water vacuum excavation units.”

Eamon Turner – Civil Supervisor – Shamrock Civil

“Thankfully we discovered this equipment, we can now non-destructively expose services in profile areas without the requirement of council permits, traffic or pedestrian management. We are all looking forward to mitigating access issues by utilizing this equipment”

Lee Towey - Civil Supervisor – CPB Cross River Rail (speaking of Vac-Ex equipment)
