DIGITAL STEWARDSHIP
02 / WHY IT MATTERS
Digital Stewardship is designed to avoid the big costs, not add to them. We reduce risk by making deterioration, significance, and vulnerability visually clear, long before they become major failures.
People interpret written reports differently, but they understand what they see. Visual evidence collapses disagreement and aligns decisions.

03 / THE EVIDENCE ENGINE
FROM BASELINE TO BETTER JUDGEMENT
Digital Stewardship creates an authoritative digital baseline and maintains it over time, so custodians can understand what is there, what has changed and what needs attention.
DIMENSIONAL EVIDENCE
A high-resolution model made to be inspected, measured and returned to.
PERIODIC REFRESH
New capture is aligned against the record so change can be found, not assumed.
INFORMED ACTION
A shared evidence base for maintenance, conservation and long-term decisions.
04 / HOW IT WORKS
An ordered process designed to preserve evidence, make change visible and support better decisions over time.
CAPTURE
Laser scanning and photogrammetry capture precise measurements and detailed visual information.
MODEL
The information is combined into a precise, fully textured AU 3D Digital Model.
MONITOR
The model provides a baseline against which future change can be measured.
COMPARE
Annual updates show what has changed, where it has changed and why it matters.
UNDERSTAND
Condition, significance and vulnerability become visible, measurable and actionable.
Each year, we update the model to show what has changed, visually and measurably.
Every update strengthens the evidence base.
EVIDENCE OUTPUTS
year-on-year comparison · deterioration tracking · movement detection · early warning · continuity independent of personnel
STEWARDSHIP INFORMATION
We provide clear, visual stewardship information that shows:
what has changed · where it has changed · why it matters · what needs attention · what can wait
Updates turn uncertainty into facts.
05 / WHAT DIGITAL STEWARDSHIP PROVIDES
One asset. One reference. Many ways to understand it.
The AU 3D Digital Model brings together precise geometry, measurement and ultra-high-resolution visual information in a single digital record of the asset.
The Aspects Unseen Model is ultra high resolution, measurable, complete, visually self-evident, conservation-grade and easy to understand. Everything else in Digital Stewardship flows from this single source of truth.
The single source of truth for Digital Stewardship.

06 / APPLICATIONS
A common reference across portfolios of complex physical assets.
WINTON CASTLE
HISTORIC BUILDINGS
Buildings whose architectural, historical or cultural significance requires an accurate and maintained record.
CHURCHES
Precise evidence for condition, conservation, fundraising and long-term stewardship.
ESTATES
A shared evidence base for buildings and structures managed across complex historic sites.
DUNBAR CASTLE / HARBOUR
SIGNIFICANT STRUCTURES
Structures where deterioration, vulnerability or difficult access make reliable monitoring particularly valuable.
07 / CASE STUDY LIBRARY
The Case Study Library demonstrates how Digital Stewardship works in practice across a range of historic assets.
Each example shows how a maintained digital baseline, structured monitoring and significance-led assessment provide clear, practical value for custodians.

08 / WHO WE ARE
We help owners, trusts, councils, and heritage bodies make defensible, evidence-based decisions about historic fabric.
OUR ROLE IS SIMPLE
We do not replace conservation judgement. We support it by providing:
measurable evidence
true-to-scale documentation
mapped condition
mapped significance
identified vulnerabilities
monitoring cycles
continuity independent of personnel
Digital Stewardship strengthens the work of conservation architects, surveyors, planners, trusts, estates, and heritage bodies
by giving them a shared, defensible evidence base.
09 / LONG-TERM PARTNERSHIP
continuity
regular monitoring
updated evidence
reduced risk
predictable cost
stable stewardship
Our purpose is to make advanced technology genuinely useful, but never a barrier, for custodians.
10 / WHY IT IS COST EFFECTIVE
AVOIDING BIG COSTS
Digital Stewardship identifies early-stage deterioration, weathering, movement, moisture impact, vulnerable carved detail and exposed elevations before they escalate into emergency works, structural failures, fabric loss, high-risk interventions or accelerated deterioration.
Early visibility saves money.
PREDICTABLE STEWARDSHIP
Digital Stewardship replaces unpredictable, reactive spending with planned, predictable stewardship.
continuity · regular monitoring · updated evidence · stable decision-making · predictable cost · reduced risk exposure
Predictability is cost control.
RISK AVOIDANCE
The most expensive heritage decisions are the ones made without clear evidence.
Visual certainty reduces governance disagreement, misinterpretation, conflicting reports, unnecessary interventions, delayed interventions and planning friction.
Shared evidence reduces risk, and risk reduction is cost reduction.
11 / RESEARCH
CONDITION MONITORING
Published work on condition monitoring and change detection reinforces the value of observing deterioration as it develops, rather than waiting for isolated inspections to reveal a problem. Digital Stewardship provides a stable visual baseline for that ongoing comparison.
DOCUMENTATION + EVIDENCE
Research on digital documentation and conservation supports evidence that can be revisited, interpreted and shared. Reliable visual evidence makes condition legible across specialists, custodians and decision-makers without reducing conservation judgement to a report.
LONG-TERM MANAGEMENT
Monitoring is most useful when it becomes part of long-term asset management. A maintained record helps identify emerging vulnerability, supports prioritisation, and gives future teams a dependable starting point for action.
CONTINUITY OVER TIME
Episodic inspection and reporting can lose context between visits. Comparable evidence gathered over time preserves continuity, allowing change to be understood in relation to an earlier condition rather than reconstructed from memory or fragmented records.
