DIGITAL STEWARDSHIP

A new discipline for physical assets

Digital Stewardship

A continuous, evidence-based system for understanding and caring for your assets.
A precise Digital Model and Issues List make condition, significance and change visible over time.

01 / INTRODUCTION

02 / WHY IT MATTERS

Historic buildings change slowly, and often invisibly.

Historic buildings change slowly, and often invisibly.

THE PROBLEM

Small defects — moisture impact, cracking, failing gutters, slipped slates, weathering and surface deterioration — can be difficult to identify and track without a structured evidence base.

Digital Stewardship makes change visible.

Digital Stewardship makes change visible.

THE RESPONSE

A reliable, measurable record is maintained and interpreted over time, giving custodians continuity of evidence for proportionate, defensible decisions: what needs attention, what can wait and where specialist input may be required.

01 / CHANGE CAN BE HARD TO SEE

02

RECORDS CAN BE FRAGMENTED

Information about a building can be incomplete, outdated or spread across surveys, reports, drawings and other records.

03

KNOWLEDGE CAN BE LOST

When trustees, staff or advisers change, important knowledge about the asset can be lost with them.

04

REACTIVE ACTION CAN BE COSTLY

Without current evidence, relatively small issues can become larger problems, leading to emergency repairs, disruption and avoidable expenditure.

03 / THE EVIDENCE ENGINE

MODEL + INTERPRETATION + CHANGE

The Evidence Engine

The Evidence Engine

At the heart of Digital Stewardship, the Digital Model and professionally interpreted Issues List form the Evidence Engine. The Digital Model shows what is there. The Issues List explains what matters. The Evidence Engine shows how the asset is changing over time.

DIGITAL MODEL

The measurable element: a precise, evidence-grade 3D record combining accurate geometry with high-resolution surface imagery.

ISSUES LIST

The interpreted element: professional conservation judgement about condition, significance, vulnerability, change, risk and urgency.

EVIDENCE OVER TIME

Revisited over time, new evidence is compared with earlier records to show what is stable, what is changing, where vulnerabilities are emerging and where proportionate action may be required.

04 / HOW IT WORKS

Digital Stewardship turns an accurate baseline into a continuing understanding of the asset.

Digital Stewardship turns an accurate baseline into a continuing understanding of the asset.

A continuous evidence cycle that supports professional decision-making; it does not replace conservation architects, structural engineers, surveyors or other specialists.

01 / CAPTURE

Accurate laser scanning and evidence-grade imagery create the Digital Model: a precise, measurable record of the structure.

02 / INTERPRET

Professional conservation judgement is organised into the Issues List, identifying condition, significance, vulnerability, change, risk and urgency.

03 / REFRESH

At agreed intervals, new evidence is captured, the Digital Model is updated and the Issues List is reviewed.

04 / COMPARE

Current records are compared with previous evidence to identify what is stable, what is changing and where emerging issues require attention. Significant weather events can trigger a new capture, allowing direct comparison with the previous record.

05 / ESCALATE

Where specialist consideration is needed, the issue is clearly identified and supported with the relevant evidence. Digital Stewardship indicates where specialist input may be appropriate and supports the client’s next step.

Successive evidence records make change clear.

Successive evidence records make change clear.

Digital Stewardship keeps evidence current and comparable, so understanding is carried forward between review points rather than rebuilt from a one-off survey.

COMPARISON CREATES CONTINUITY

WHAT THE RECORD REVEALS

stable condition · emerging change · vulnerable fabric · documented context

THE ROLE OF SPECIALISTS

The evidence supports informed assessment; it does not replace specialist judgement.

conservation architects · structural engineers · surveyors · other appropriate specialists

The value lies in comparing successive records: clearer evidence, proportionate action and continuity over time.

05 / WHAT DIGITAL STEWARDSHIP PROVIDES

One asset. One reference. Many ways to understand it.

The Digital Model is the precise, evidence-grade 3D record of the asset, combining accurate geometry with high-resolution surface imagery.

The Issues List adds professional interpretation — recording condition, significance, vulnerability, change, risk and urgency. Together, they form the Evidence Engine: a maintained evidence base that can be revisited and compared over time.

WHOLE BUILDING STEWARDSHIP

THE COMPLETE RECORD

A complete Digital Model, evidence-grade imagery, interpreted condition and an Issues List: the foundation for scheduled Refreshes and comparison over time.

WHAT IT PROVIDES

A continuing evidence base that identifies emerging change and vulnerability, supports appropriate escalation, and preserves continuity across personnel and governance changes.

PROPORTIONATE SCOPE

Digital Stewardship can be proportionate to the asset, the risk and the resources available.

START WHERE EVIDENCE MATTERS MOST

EXPAND WITH CONFIDENCE

Begin with roof interfaces, vulnerable elevations, significant interiors, historic fabric, individual structures or another defined area of concern — then expand as priorities and resources allow.

07 / CASE STUDY LIBRARY

08 / WHO WE ARE

We are Digital Stewards.

We are Digital Stewards.

We help owners, trusts, councils, and heritage bodies make defensible, evidence-based decisions about historic fabric.

OUR ROLE IS SIMPLE

We create and maintain the evidence base for each asset — a precise Digital Model combined with professional interpretation through the Issues List.

We create and maintain the evidence base for each asset — a precise Digital Model combined with professional interpretation through the Issues List.

We do not replace conservation judgement. We support it by providing:

WHAT WE RECORD

measurable evidence

true-to-scale documentation

mapped condition

WHAT WE CARRY FORWARD

mapped significance

identified vulnerabilities

monitoring cycles

continuity independent of personnel

We work alongside existing professionals.

We work alongside existing professionals.

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

Stewardship depends on continuity, not one-off surveys.

THE VALUE OF CONTINUITY

Each review builds on the last. The evidence remains comparable, the Issues List evolves with the asset, and important knowledge is carried forward rather than recreated from scratch.

10 / WHY IT IS COST EFFECTIVE

Why It Is Cost Effective

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 can reduce the likelihood of costly reactive work.

PREDICTABLE STEWARDSHIP

Digital Stewardship supports a shift from unpredictable, reactive spending towards planned, predictable stewardship.

continuity · regular monitoring · updated evidence · stable decision-making · predictable cost · reduced risk exposure

Predictability is cost control.

RISK AVOIDANCE

Decisions made without clear evidence can increase cost, risk and uncertainty.

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.

STRONGER FUNDING APPLICATIONS

A maintained evidence base provides funders with clear evidence of condition, need and proposed intervention — helping custodians make a stronger, more defensible case for investment.

11 / RESEARCH

Research and Evidence

Research and Evidence

Digital Stewardship is built around the principle that long-term stewardship decisions should be supported by reliable evidence, continuity of records and structured monitoring.

Digital Stewardship is built around the principle that long-term stewardship decisions should be supported by reliable evidence, continuity of records and structured monitoring.

RELIABLE RECORDS

Reliable records help preserve institutional knowledge, maintain continuity and make evidence available when decisions are needed.

MONITORING CHANGE

Structured monitoring helps identify change over time and understand emerging deterioration in relation to previous evidence.

PLANNED STEWARDSHIP

Structured evidence supports planned rather than purely reactive maintenance, and provides a stronger basis for conservation and funding decisions.

RESEARCH AND DEVELOPMENT

We are exploring whether AI-based image comparison can support identification of measurable change within evidence-grade imagery. This work is exploratory; any future integration would require conservation-grade validation and support, not replace, professional judgement.

Digital Stewardship applies these principles in practice through a maintained Digital Model, an Issues List and periodic comparison of successive evidence records — supporting, not replacing, professional judgement.
