Richmond Mixed-Use Redevelopment – Desktop Assessment

  • Location: Richmond, VIC
  • Scope: Desktop Environmental Due Diligence
Terralis undertook a desktop environmental risk screening to support a planning application. The site had commercial use history with minor redevelopment. No indicators of significant environmental contamination were noted, supporting efficient planning approvals.

Elsworth Street Light Industrial Redevelopment – Contamination Investigation

  • Location: Canadian (Ballarat), VIC
  • Client: Industrial Land Owner
  • Scope: Phase I Environmental Site Assessment
Terralis assessed the site of a former light-industrial site in Canadian for soil and groundwater contamination. The report supported a transition to commercial/light-industrial redevelopment, with no EPA Audit required. Soil sampling confirmed the absence of significant contamination risks.

Pakington Street Commercial Redevelopment – Construction Environmental Management Plan (CEMP)

  • Location: Newtown, VIC
  • Client: Architecture Firm
  • Scope: Construction Environmental Management Plan (CEMP)

Terralis prepared a comprehensive Construction Environmental Management Plan (CEMP) to support the redevelopment of a former residential property into a modern childcare centre at 410 Pakington Street, Newtown. The CEMP was required by the City of Greater Geelong as part of planning approval conditions.

The plan addressed a range of environmental and community considerations, including:
– Dust, sediment, and stormwater control
– Soil stockpile and excavation management
– Waste minimisation and clean fill protocols
– Vegetation protection and asbestos risk management
– Community engagement and complaints response

The CEMP was informed by a prior geotechnical investigation and tailored to mitigate risks associated with legacy fill and site disturbance. It provided the practical framework to ensure construction activities complied with EPA Victoria’s General Environmental Duty and other statutory obligations.

Mixed-Use Redevelopment – Essendon Service Station

  • Location: Essendon, VIC
  • Client: Commercial Developer
  • Scope: Preliminary and Detailed Site Investigations (PSI & DSI)
Terralis was engaged to assess a prominent corner allotment formerly occupied by a petrol station and garage. Investigations included borehole sampling and groundwater assessment. The project supported a mixed-use commercial and residential redevelopment with EPA engagement.

Tarneit – Environmental Site and Hydro Assessment

  • Location: Tarneit, VIC
  • Client: Residential Developer
  • Scope: Contaminated Land and Hydrogeological Assessment for Residential Development

Terralis conducted a comprehensive environmental and hydrogeological assessment of a 4.6-hectare parcel within the Tarneit North PSP area to support a proposed residential subdivision. The site, previously used for rural-residential activities and later impacted by waste dumping and suspected clandestine activity, presented elevated contamination risks.

Our scope included:
– Historical and regulatory review of the site.
– Completion of 23 soil sampling points and laboratory analysis of 27 samples.
– Desktop assessment of surface water, hydrogeology and salinity risk.
– Identification of impacted zones from domestic and potential hazardous waste.
– Recommendations for hazardous materials audit, remediation planning, and waste classification.

Terralis concluded that site contamination—mainly in the southern portion—is manageable and does not necessitate a full environmental audit, provided a remediation and validation program is implemented. The site is suitable for sensitive use, contingent on proper clean-up and decommissioning of the existing dam.

West Footscray – Tier 1 Landfill Gas Risk Assessment

  • Location: West Footscray, VIC
  • Client: Local Council
  • Project Type: Landfill Gas Risk Assessment for Proposed Park Redevelopment

Terralis was engaged to assess potential landfill gas (LFG) risk at a former industrial property earmarked for community open space redevelopment. The site was formerly used for fuel distribution and service station operations, which raised concerns about residual gas emissions from contaminated soils or buried hydrocarbon sources.

Our services included:
– Desktop review of historical land uses and aerial imagery.
– Field inspection to verify surface conditions and infrastructure.
– Assessment of LFG risk in accordance with EPA Victoria’s Best Practice Environmental Management (BPEM) for Landfills (Siting, Design, Operation and Rehabilitation).
– Evaluation of potential gas migration pathways and receptor risks.

The assessment concluded a **negligible risk of landfill gas generation**, given the absence of landfill-type materials, a lack of waste burial evidence, and no significant organic contamination. No further LFG monitoring or mitigation was deemed necessary, enabling the Council to progress confidently with park planning.

Torquay Primary School Site – Environmental Audit Support

  • Location: Torquay, VIC
  • Client: School Authority
  • Scope: Detailed Site Investigation (DSI) for Environmental Audit Overlay compliance
Terralis (as the acting environmental consultant) conducted a comprehensive Detailed Site Investigation (DSI) for a 3-hectare site earmarked for development into a primary school. The site, previously used for rural residential and agricultural purposes, required assessment for potential contamination due to legacy pesticide use (including Dieldrin). Soil and groundwater sampling confirmed localized contamination risks. Targeted assessments and validation were completed to support a Statutory Environmental Audit under the Environmental Audit Overlay.

Potable Water Reservoir Inspection – South East Victoria

  • Service: UAV Asset Inspections
  • Client: Catchment Management Authority
Terralis provided drone-based visual inspection services for a suite of potable water reservoirs across South East Victoria. Using high-resolution aerial and internal UAV systems, our team supported detailed assessments of structural integrity both above and below the waterline. Defects were captured in annotated 3D models and as-constructed drawings. Deliverables included RPEQ-certified reports, remedial recommendations, and cost estimates for structural repairs.

Industrial Steel Infrastructure Inspection – Rural Bridge

  • Service: Confined Space Drone Inspection of Internal Steel Members
  • Client: VicRoads (via subcontracted engineering inspection)
Terralis supported inspection planning and drone-enabled data acquisition for the internal steel structure of a small rural bridge. The project involved navigating drone systems through confined orthotropic decks, cross beams, and web plates, enabling close visual inspection (CVI) of hard-to-access areas without the need for scaffolding or man entry.

Remote Dam and Spillway Survey – Regional Victoria

  • Service: Photogrammetry and Orthomosaic Mapping
  • Client: Agricultural
Terralis deployed RTK-enabled drones to conduct a topographic survey of medium sized agricultural dam and drainage channel. The orthomosaic outputs and digital elevation models (DEMs) were used for embankment stability analysis and to assess sediment accumulation. This service allowed engineers to model catchment inflows and improve asset management strategies without requiring ground-based survey access.

Urban Stormwater Network Mapping – Greater Geelong

  • Service: UAV Mapping with AI-Assisted Flow Path Analysis
  • Client: Local Government
Leveraging multispectral and RGB drone data, Terralis performed aerial mapping of an urban stormwater system. The project aimed to identify bottlenecks, overland flow paths, and debris blockages. Outputs fed into a GIS-based stormwater model to assist engineers in identifying flood-prone areas.

Wurdibuloc Vegetation Encroachment Monitoring – Transmission Easements

  • Client: Infrastructure Asset Manager
  • Service: Multispectral Drone Survey & Change Detection
Terralis conducted a vegetation encroachment audit for high-voltage transmission corridors using NDVI-capable drones. AI-assisted image classification was used to identify regrowth hotspots and inform targeted maintenance, significantly reducing the need for foot patrols.
