Predictive Modelling
De-Risking Projects with Archaeological Predictive Modelling
Archaeological predictive modelling transforms how we find, protect, and manage cultural heritage. By combining high-resolution spatial data, historic records, environmental variables with expert field knowledge, our models identify areas of high archaeological potential before the shovel touches any soil.
This targeted approach reduces project risk, saves time and budget, and ensures compliance with regulatory frameworks while safeguarding significant sites for future generations. This approach also allows early design options to be chosen intelligently to de-risk projects at every step.
Our spatial solutions integrate advanced GIS, remote sensing and generative AI techniques to deliver clear, evidence-based predictions and actionable maps tailored to your project needs.
Whether for development planning, environmental assessment, or heritage conservation, we provide transparent workflows, robust metadata and practical recommendations that support informed decision-making.

Testimonials
Sector Manager | Millar Merrigan
ACHM has consistently provided us with expert advice on Aboriginal cultural heritage matters, including the preparation of Cultural Heritage Management Plans. They’re great to work with—professional, competitively priced, and reliable in meeting timeframes. Their practical approach and responsiveness make them a valued partner on our projects.
Chief Executive Officer | Banjima Native Title Aboriginal Corporation
ACHM are engaged extensively across Banjima Country and they provide exceptional expertise, professionalism, customer service and a genuine passion for preserving and promoting cultural heritage. ACHM goes beyond mere consultancy through consistently delivering professional services, solutions and best practice in every thing they do.
Senior Development Manager | Dav Consulting
We recently engaged ACHM to manage extensive Cultural Heritage Artefact Salvage Operations for an expansive and complex greenfields development site on north side of Melbourne. The diligence, open communication, efficiency and positive outcomes achieved by the ACHM Team, including in their coordination and management of the local RAP, was first class, and made my job as Development Manager substantially easier. Cannot recommend highly enough
Senior Development Manager | Avid
I have been a client of ACHM for over a decade and have engaged their services across four large-scale projects. Throughout this time, their dedication and professionalism have remained consistently impressive. ACHM excels at managing client expectations while operating sensitively within complex environments. They are highly skilled at guiding clients through cultural heritage approval processes, striking the delicate balance between client priorities and cultural sensitivities. I highly recommend ACHM for their expertise and commitment.

Frequently Asked Questions
What is archaeological predictive modelling?
Archaeological predictive modelling usually uses GIS to predict where Aboriginal and historical heritage sites are most likely to occur within a landscape. It combines known site records, environmental variables, historical sources and expert knowledge to map relative archaeological potential, helping proponents understand heritage risk and plan fieldwork before ground disturbance begins.
How does predictive modelling reduce project risk?
By mapping areas of varying archaeological sensitivity early, predictive modelling shows where heritage constraints are likely to occur before design is finalised. Proponents can avoid sensitive landforms, focus survey effort where it matters and budget realistically for assessment, reducing the chance of unexpected finds, stop work events, approval delays and cost overruns.
What data is used in an archaeological predictive model?
Typical inputs include registered and recorded heritage sites, landform and geomorphology, distance to water, geology and soils, vegetation, elevation and slope, and historical land use and disturbance. Ethnographic and historical records, together with Traditional Owner knowledge where it is shared, add cultural context that environmental data alone cannot capture.
Does predictive modelling replace an archaeological survey?
No. A predictive model indicates relative likelihood, not the confirmed presence or absence of cultural heritage values. It guides where and how intensively to survey, but field survey, subsurface testing where required and Traditional Owner involvement remain necessary to identify heritage places and satisfy regulators and statutory approval processes.
When should predictive modelling be done on a project?
At the earliest planning, feasibility or site selection stage, ideally before land is acquired or designs are fixed. Modelling at this point lets project teams compare options, steer infrastructure away from high sensitivity areas and build realistic heritage timeframes and budgets into the program from the outset.
How is predictive modelling used for renewable energy and transmission projects?
Wind, solar and transmission projects often cross large, varied landscapes, making blanket field survey costly and slow. Predictive modelling helps refine turbine, solar panel or tower layouts and route corridors, directing survey to higher potential areas and supporting earlier, better informed decisions that protect heritage and keep approvals on track.
How is predictive modelling different from statutory sensitivity mapping?
Statutory sensitivity mapping, such as Victoria’s areas of cultural heritage sensitivity, is a legal trigger based on defined landform types and categories. Predictive modelling is a more specific analysis that ranks archaeological potential using many variables. Land outside a mapped sensitivity area can still contain Aboriginal heritage, which modelling helps to identify.
How accurate is archaeological predictive modelling?
Accuracy depends on the quality and coverage of site records, the resolution of environmental data and how well the model is tested against field results. Reliable models are transparent about their assumptions, report confidence levels and are refined as survey data comes in, rather than presenting predictions as certainties.
Can AI and remote sensing improve archaeological predictive modelling?
Yes. Remote sensing such as LiDAR, aerial and satellite imagery reveals subtle landforms, vegetation patterns and disturbance that inform site likelihood. Machine learning and generative AI can help process large datasets and test variables, although expert archaeological judgement and Traditional Owner knowledge remain essential to interpret results responsibly.
Can predictive modelling support statutory heritage approvals?
Yes, as supporting evidence. A transparent, well documented model can justify survey design, sampling strategy and the focus of test excavations within a CHMP or heritage assessment. Regulators and Traditional Owners still expect field verification, so the model should strengthen, not substitute for, the evidence behind an approval.
What does a predictive modelling report include?
A predictive modelling report typically includes sensitivity maps ranking archaeological potential, a description of data sources and variables, the method and assumptions used, limitations and confidence levels, and practical recommendations for survey, design and management. Spatial outputs are usually supplied as GIS layers ready for engineering and planning teams.
