Service index
Assess. Consult. Perform.
Every service Sovereign offers, grouped by the phase of work it belongs to. The firm self-performs its construction, which is why a site can go from first sample to regulatory closure without changing hands.

§01 Assess
Find out what is actually there
Before anything is designed or dug, the site has to be characterised — the extent, the pathway, the receptor and the regulatory frame. Assessment is where the cost of a project is really decided.
ASS-01
Soil / Groundwater Characterization
Delineating the nature and extent of impact across soil, groundwater and soil vapour.
ASS-02
Hydrogeology / Groundwater Modeling
Flow and transport modelling to predict where a plume goes and how a remedy will perform.
ASS-03
detail →PFAS Investigation and Remediation
Sampling, assessment and treatment for per- and polyfluoroalkyl substances.
ASS-04
Indoor Air Quality / Vapor Intrusion
Sub-slab, indoor air and ambient sampling to evaluate the vapour intrusion pathway.
ASS-05
Due Diligence / Property Transactions
Phase I and Phase II assessment on transaction timelines that do not move.
ASS-06
Wetlands Delineation
Boundary delineation and reporting to support permitting and site planning.
ASS-07
Biological Assessment and Ecological Evaluation
Habitat, species and ecological risk evaluation to support permits and remedy selection.
ASS-08
Drone Services
Aerial survey and imagery for site mapping, volumetrics and inspection access.
ASS-09
Project Greenhouse Gas Emissions Tool (PGT)
Quantifying the carbon footprint of remediation activity so it can be reduced with data.
§02 Consult
Decide what to do about it
Between the data and the dig sits the decision: which remedy, which permit, which regulatory path, and what it costs to reach closure. This is the work that determines whether a site progresses or stalls.
CON-01
Environmental Program Management
Running a portfolio of sites to one standard, one schedule and one cost basis.
CON-02
Regulatory Compliance / Permitting
Federal, state and local permitting strategy, applications and agency negotiation.
CON-03
Risk Management
Quantifying environmental exposure so it can be carried, transferred or retired.
CON-04
Health Risk Assessment
Human health and ecological risk assessment supporting remedial decision-making.
CON-05
Innovative Remediation Technology
Bench and pilot evaluation of treatment technologies before full-scale commitment.
CON-06
Brownfield Redevelopment
Turning constrained, impacted parcels back into developable property.
CON-07
Land Development
Environmental and engineering support sequenced against a construction programme.
CON-08
Geotechnical Services
Subsurface investigation and geotechnical design to support construction.
CON-09
Litigation Support / Expert Testimony
Technical analysis, reporting and testimony in environmental disputes.
CON-10
Insurance Support
Cost-to-closure work for underwriters, claims teams and policy holders.
CON-11
Coastal Natural Resources
Shoreline, marsh and coastal habitat design, permitting and restoration.
CON-12
Urban Natural Resources
Ecological restoration and green infrastructure in the built environment.
CON-13
Greenspaces Natural Resources
Planning and restoration of parks, preserves and open space.
CON-14
Specialized Natural Resources
Species-specific and habitat-specific studies where standard protocols do not apply.
CON-15
Solar Energy Services
Siting, permitting and design for solar on landfills, rooftops and constrained land.
§03 Perform
Build it, run it, close it out
Sovereign self-performs. Remediation systems, treatment plants, pump stations and demolition are delivered by the firm's own construction group, which is why schedule and cost stay under one roof.
PER-01
detail →Construction – Water / Wastewater
Treatment plants, pump stations, conveyance and process mechanical installation.
PER-02
Construction Management
Owner-side management of environmental and infrastructure construction.
PER-03
Soil / Groundwater Remediation
In-situ and ex-situ remediation from design through regulatory closure.
PER-04
Remediation System Installation and Maintenance
Installing, commissioning and maintaining active treatment systems.
PER-05
Operation / Maintenance / Optimization
Long-term O&M with optimisation to cut runtime, energy and cost.
PER-06
Demolition / Decommissioning
Structure and process decommissioning ahead of site closure or redevelopment.
PER-07
Radiological Services
Characterisation, remediation and licensing support for radiological impact.
PER-08
Landfill Services
Cap design, gas and leachate management, and post-closure care.
PER-09
Mine Closure, Reclamation, and Management
Closure planning, reclamation design and long-term management of mine sites.
PER-10
Mining
Environmental support to active mining operations and permitting.
PER-11
Permitting, Compliance, and Mitigation
Construction-phase permitting, compliance monitoring and mitigation delivery.
PER-12
Disaster Response, Recovery, and Resilience
Mobilised response, assessment and recovery after storms, fires and floods.
