6 THE BUILDING CONSERVATION DIRECTORY 2024 CATHEDRAL COMMUNICATIONS Foreword Sixty years ago, the organization that would become World Monuments Fund (WMF) was founded by retired US Army Colonel James A Gray. His mission was clear: to fill the need for a non-governmental organization capable of mobilizing to safeguard the cultural treasures not just of one country but of humanity as a whole. Those early years saw the launch of projects at some of the world’s most iconic heritage places. At Rapa Nui (also known as Easter Island), Chile, we launched the Moai Conservation Project to preserve the island’s extraordinary sculptures. At the Rock-Hewn Churches of Lalibela, Ethiopia, we documented and stabilized the fragile stone structures, one of the most important religious sites on the African continent. And at Venice, we mounted a campaign to save the city’s irreplaceable architectural gems in the wake of the disastrous flooding of 1966, which left contaminated seawater sloshing across palace floors and seeping into priceless works of art. Decades on, we are still guided by the belief that working together to preserve our shared cultural heritage can ensure a better future for humanity. Through initiatives like the World Monuments Watch, our flagship advocacy program, we have championed a bottom-up, people-first approach to preservation, working alongside and in accordance with the needs of the local communities who care for these places. Since our founding, we have worked at 700 sites in 112 countries, undertaking everything from physical conservation interventions to oral history projects to educational programming. Indeed, the latest cycle of the World Monuments Watch even included the Moon, spotlighting timely conversations around the preservation of the first lunar missions’ landing sites as we enter a second Space Age. Though our project portfolio may be diverse, it is united by a desire to use preservation to tackle the most urgent challenges facing society today. Through efforts like our Climate Heritage Initiative, doubling down on our longtime commitment to work at the climate-heritage nexus. The initiative has so far committed over $15 million towards projects that use conservation to mitigate the impacts of climate change, from rehabilitating traditional stepwells in India to pioneering strategies for hardier historic gardens in France. The threats facing cultural heritage continue to evolve, but our field has risen to meet them. The contents of this issue of The Building Conservation Directory are a testament to innovation in the face of novel challenges. Today, WMF is part of a global movement of people united in a commitment to safeguarding the world’s most treasured places. We are grateful for all those who share our dedication to protecting our shared heritage, whatever form it takes. Bénédicte de Montlaur President and CEO, World Monuments Fund

11 CATHEDRAL COMMUNICATIONS THE BUILDING CONSERVATION DIRECTORY 2025 PROFESSIONAL SERVICES 1 GEOSPATIAL SURVEYS Why getting it right matters ANDY BEARDSLEY The new document also supersedes Historic England’s 3D Laser Scanning for Heritage 2018 guide, as technological advancements and the increasing integration of geospatial surveys into heritage conservation since 2018 mean that the guide is now outdated. Another Historic England guide, Understanding Historic Buildings: A Guide to Good Recording Practice remains in use. However, while this 2016 document is useful for historical analysis, it fails to adequately reference the geospatial specifications, leading many conservation professionals to assume that basic recording methods are sufficient for full geospatial survey. This creates a potentially dangerous stumbling block where professionals believe they are using data that complies with best practice when, in fact, they are working with incomplete or inaccurate survey data. The two documents serve very different purposes. WHEN TO USE THEM Historic England’s Geospatial Survey Specifications The table overleaf lists some of the many applications for accurate and detailed geospatial survey data. However, there is no explicit directive detailing when a geospatial survey must be undertaken, apart from the requirement for recording where a A 3D geospatial survey of St Mary Abchurch, one of Wren’s city of London churches: 3D laser scanning captures the detailed information required for draughting CAD drawings (All images: Terra Measurement Limited) CROSS THE heritage sector, two critical issues are quietly undermining conservation efforts: the rise of easily accessible but poorly controlled 3D survey data, and the neglect of commissioning best practice geospatial surveys for building conservation projects. Many heritage professionals, estate owners and developers misunderstand the role and need for 3D geospatial surveys. Decision makers often procure or approve services based on cost rather than capability, unaware that incorrect data can set projects back years. The ill-informed decisions that follow lead to poor cost analysis, the misalignment of new work and compromised monitoring strategies. The result is wasted funds and risks irreversible damage to heritage assets. So how do we fix this? By understanding what makes a geospatial survey reliable, commissioning the right expertise, and, above all, adhering to Geospatial Survey Specifications for Cultural Heritage 2024—a specification framework published by Historic England that is equally relevant in all corners of the UK. Historic England’s guidance is now well established as the go-to standard for 3D geospatial surveys. The processes it outlines are essential for ensuring that the detailed information required for draughting CAD drawings and building 3D models is captured correctly. The guidance provides a benchmark for accuracy and consistency in geospatial data collection and ensures that surveys are both technically sound and practically useful. There is no accurate alternative: all previous methods are obsolete for anything other than sketch drawings. Despite its critical importance, , yet it is too often overlooked. In this article I hope to demonstrate that a 3D geospatial survey undertaken with the appropriate controls benefits the building and the design team in many ways, potentially for decades ahead. A brief glossary of technical terms is included at the end. THE EVOLUTION OF HISTORIC ENGLAND’S GEOSPATIAL SURVEY SPECIFICATIONS Originally developed as the Metric Survey Specifications for Cultural Heritage (English Heritage, 2009), Geospatial Survey Specifications for Cultural Heritage has been refined over many years of practice and research, and the core principles have remained consistent.
12 THE BUILDING CONSERVATION DIRECTORY 2025 CATHEDRAL COMMUNICATIONS heritage asset or some part of it is to be lost (NPPF section 16, for example). Applications for listed building consent are made through the local planning authorities, and the national heritage authorities are only consulted on applications affecting buildings of the highest grades (I and II* in England and Wales, and Category A in Scotland). In most cases it is therefore up to the local authority alone to advise on whether a proper geospatial survey should be undertaken, and many local authorities no longer employ any conservation officers. While there is no strict legal mandate specifying when Geospatial Survey Specifications for Cultural Heritage should be followed, surveys conducted to these standards provide critical data for effective conservation, restoration and management. For planning applications and listed building consents, robust documentation together with precise evidence of the building’s current state helps justify proposed works and demonstrates compliance with conservation principles and regulatory requirements. For pre-conservation monitoring and quinquennial inspections, high-accuracy 3D geospatial surveys enable conservation to be properly planned by providing a baseline record of the building’s existing condition, capturing fine architectural details, structural deformations and the form of historical fabric. This helps to ensure that any intervention is based on verifiable data rather than assumptions, Long-term condition monitoring and proactive maintenance depends on establishing accurate benchmarks for detecting subtle changes in the structure over time. and is essential for heritage management, particularly for structures vulnerable to environmental or structural risks. and ensuring responsible stewardship. By carrying out periodic re-surveys, stakeholders can make data-driven decisions about maintenance and repair strategies, ultimately reducing long-term costs and ensuring better preservation outcomes. For structural assessments, comparing data from repeat surveys enables movement, subsidence or deformation to be identified over time, reducing risk and improving decision-making. For heritage documentation, creating a high-resolution digital archive ensures that historical data is preserved for future research and conservation. Property owners, architects and conservation professionals have a duty of care to historic buildings. Ensuring best practices are employed should not be seen as optional but as an ethical and professional obligation. SUPPORTING ONGOING MAINTENANCE AND REPAIRS Geospatial surveys provide an essential baseline for monitoring changes in a building over time. By capturing a structure’s geometry with millimetre precision, they allow conservation teams to detect subtle structural movements or deformations before they lead to major failures. Material degradation trends can be identified, helping to prioritise conservation efforts. And the data can be used to track the effectiveness of past repairs and restoration interventions. One of the greatest challenges in heritage conservation is the inevitability of change. Buildings decay, materials erode and, in some cases, natural disasters strike. Climate change in particular poses a serious threat, with rising temperatures, increased rainfall and extreme weather events accelerating material decay. Geospatial monitoring allows conservationists to anticipate change and to take steps to mitigate its impact. Climaterelated damage can be predicted by tracking erosion, water infiltration and subsidence in vulnerable sites, and by assessing the impact of temperature fluctuations on traditional materials. and by providing critical data for coastal heritage sites at risk from rising sea levels. With accurate datasets in place, conservation planners can proactively design adaptation strategies that safeguard heritage assets for future generations. ENHANCING PUBLIC ENGAGEMENT AND DIGITAL ACCESS The digital preservation of historic sites isn’t just about conservation, it also opens new opportunities for public engagement, education and accessibility. High-resolution 3D geospatial data can be adapted for: Virtual reality (VR) and augmented reality (AR) experiences, allowing people to explore heritage sites remotely Interactive museum exhibits, providing detailed reconstructions of how buildings evolved over time Digital storytelling initiatives, where layered data can illustrate historical phases and changes in construction methods. The ability to digitally preserve and share historic spaces ensures that even if access to a site is restricted, its cultural value remains accessible to the world. A meshed and textured 3D model produced from data collated by 3D geospatial survey undertaken with the appropriate controls serves as a definitive record of a structure’s condition at a specific point in time. USES OF 3D GEOSPATIAL SURVEY DATA Archaeological and historical research, enabling scholars to analyse and interpret structural changes over time Structural monitoring, identifying issues such as movement, subsidence or degradation before they become major problems Heritage impact assessments, ensuring informed decision-making when planning interventions Digital reconstructions, allowing lost buildings or earlier forms of a building to be recreated virtually for research, education or tourism Tourism and public engagement, through interactive 3D models and augmented reality experience Building information modelling (BIM) integration, supporting architects and engineers in restoration and adaptive reuse or retrofit projects Disaster planning and response, ensuring that if a heritage site is damaged, accurate reference data exists for restoration Tourism and public engagement, through interactive 3D models and augmented reality experiences.
13 CATHEDRAL COMMUNICATIONS THE BUILDING CONSERVATION DIRECTORY 2025 PROFESSIONAL SERVICES 1 LOOKING AHEAD Geospatial technologies are constantly evolving and as they advance their applications in heritage conservation will become even more powerful. The future of heritage documentation lies in greater integration with: Artificial intelligence (AI) for automated feature recognition and structural analysis Machine learning models that predict material decay and suggest preventative measures UAV/drone-based LiDAR and multi-sensor scanning (thermal imaging and LiDAR), allowing for faster and more detailed surveys in hard-to-reach areas. By embracing these technological advancements, heritage professionals can enhance efficiency, improve accuracy and ensure long-term sustainability in conservation work. CASE STUDY ONE: DUDLEY CASTLE The survey of Dudley Castle is a striking example of how geospatial surveying, delivered in line with Historic England’s Geospatial Survey Specifications for Cultural Heritage, can shape the future of heritage conservation. Situated in the West Midlands, the medieval castle dates to the 11th century and has undergone centuries of transformation, weathering wars, fires and decay. In recent years, conservation efforts have required a detailed and highly accurate geospatial survey to support longterm preservation. A survey control network was established across the site to help integrate different geospatial survey methods seamlessly. A topographical survey captured the existing zoo and context around the castle, and a combination of terrestrial laser scanning (TLS), digital photogrammetry and topographical survey were used to create a comprehensive dataset of the castle itself. This included both a detailed 3D point cloud and a textured meshed model. Combined, this 3D visualisation was capable of digitally representing every single item of historic fabric that any future inspection may wish to view, including individual stones, mortar joints, cracks, weathering and decay areas. Beyond meeting immediate conservation needs, the geospatial survey of Dudley Castle has implications for future planning, disaster response and public engagement. Applications For structural monitoring and predictive analysis the dataset provides a baseline for any assessments, allowing conservationists to track deterioration over time. Structural engineers can compare to subsequent surveys to identify movement, erosion or new fractures. For disaster mitigation and emergency preparedness, the 3D geospatial survey data ensures that if fire, storm damage or vandalism occurs, there is an accurate record for reconstructing lost components. The dataset aids in risk assessments, allowing planners to prioritise conservation work on vulnerable areas before disasters strike. For education and research there is now a digital dataset that can be used by universities and researchers for the analysis of architectural features and material compositions. The data supports reconstructions, helping to generate predictive models of how the castle may have looked in different historical periods. The survey exemplifies how geospatial data is not just a snapshot of the present but a long-term investment in heritage management. The dataset will serve as a reference for decades, assisting future conservationists, historians and educators in their work. CASE STUDY TWO: THE SPAB OLD HOUSE PROJECT The Society for the Protection of Ancient Buildings (SPAB) Old House Project serves as a perfect case study to show how geospatial surveys can provide vital insights for historic building conservation. SPAB acquired the Grade II*-listed building as a hands-on training project to showcase best conservation practices and traditional craftsmanship. The building had suffered years of neglect and was in a fragile state and densely overgrown. The survey was completed and delivered in line with Historic England’s geospatial survey specifications. Surveyors established a survey control network around the building to ensure millimetric accuracy in the dataset. A combination of terrestrial laser scanning (TLS), topographical survey, underground utilities survey and thermal imaging was deployed to create a comprehensive dataset. TLS provided a detailed 3D point cloud, capturing the condition of internal and external walls, structural defects and previous alterations. The geospatial survey drawings created using the 3D survey data formed the backbone of the conservation management plan, repair plans and listed building consents, identifying areas requiring urgent repair and guiding the phased repair process. Applications Structural integrity analysis: the survey revealed distortions in the timber framework and walls, allowing engineers to assess load-bearing capacity and recommend targeted. ‘passive wall prop’ interventions. Historical fabric documentation: digitally recording the building in its pre-repair state provided an accurate 3D reference for historical analysis and future repair strategies. Building history forensics: constructing an accurate 3D model from the 3D survey data allowed analysis of the different phases of the building’s development. Beyond the immediate conservation work, the geospatial survey data of the SPAB Old House Project also serves multiple long-term functions: 1 Preventative maintenance and monitoring where the 3D survey provides a baseline for monitoring future movement, decay or A drone or UAV (unmanned aerial vehicle) in use at Dudley Castle: its multi-sensor scanner combines thermal imaging and LiDAR for faster and more detailed surveys in hard-to-reach areas.

New surveys can be compared against this dataset to track progressive deterioration and inform preventative interventions. 2 Education by using the dataset for educational workshops and training programs, helping conservation professionals learn best-practice techniques. The geospatial survey is acting as a framework and content for an education legacy project to share the journey and learnings. 3 Disaster response and reconstruction so if fire, flooding or structural collapse occurs, the digital archive will enable precise restoration by providing a millimetric-accurate reference. This ensures that future reconstructions remain faithful to the original structure. 4 Public engagement and heritage awareness where the dataset has been adapted for interactive tours, allowing members of the public to explore the Old House remotely. Augmented reality applications could provide virtual overlays of the house’s construction phases, showing how it evolved over centuries. The SPAB Old House Project exemplifies how data from geospatial surveys provides a resource that can continue to support preservation, education and engagement for decades to come. THE CALL TO ACTION It is time for heritage professionals to demand better. Best-practice geospatial surveys should not be viewed as an optional luxury but as an essential foundation for responsible conservation of our built heritage. Before commissioning a survey, ask: does this provider follow Historic England’s Geospatial Survey Specifications for Cultural Heritage and what evidence do they have to support that? Is a control network being implemented for consistency, accuracy and future coordination? Is the technology or equipment appropriate for the level of detail or information required? And is this data ‘one use only’ or will it remain useful for future conservation efforts? The bottom line? Cutting corners on geospatial surveys is often a false economy. Precision, accuracy and adherence to best practice are essential for ensuring the longevity and integrity of our built heritage. The industry must move beyond outdated methods, inadequate documentation and inconsistent adoption of established standards. and recommendations, particularly since the technological and accessibility barriers to widespread adoption in the past have been broken down. The future of heritage conservation depends on it.

BRIEF GLOSSARY OF TERMS WITHIN THIS ARTICLE Terrestrial 3D laser scanning (TLS) A ground-based laser scanning technique that captures highly detailed and accurate 3D data of buildings, landscapes and structures by emitting laser pulses and measuring the reflections. Digital photogrammetry A method of extracting 3D measurements from 2D photographs by identifying common points in multiple overlapping images, often used for creating orthophotos, elevation models and textured 3D models. Topographical survey A detailed mapping survey that records natural and man-made features of the land (for example, contours, trees, buildings, roads) and their spatial relationships, typically used for planning, design and construction. 3D point cloud A collection of millions of individual 3D points captured using laser scanning or photogrammetry, forming a precise digital representation of an object’s shape and surface details. Unmanned aerial vehicle (UAV or drone) A remotely operated airborne platform equipped with sensors (for example, LiDAR, photogrammetric cameras) to capture aerial survey data for mapping, inspection and monitoring applications. Survey control network A hierarchical system of precisely measured and fixed reference points used to ensure consistency, accuracy and repeatability in geospatial surveys. Passive wall prop A non-intrusive structural monitoring device used to detect movement, displacement or deformation in walls and structures over time. 3D monitoring (from TLS) The use of repeat TLS scans to track changes in a structure by comparing multiple point cloud datasets over time, useful for detecting subsidence, deformation or structural movement. SHM monitoring (structural health monitoring) The continuous or periodic assessment of a structure’s stability, stress and condition using sensors (for example, tilt meters, strain gauges, displacement sensors) to detect early signs of deterioration or failure. LiDAR (light detection and ranging) A remote sensing method that uses pulsed laser light to measure distances and create high-resolution 3D models of terrain, buildings and vegetation. Used in aerial (UAV) and terrestrial (TLS) geospatial surveys. The SPAB Old House project photographed from the air by a drone and, below, representations of one elevation from the 3D survey data. Once a gatehouse chapel, its original medieval structure has been added to and extended over the years. The survey data is invaluable for unpicking its history.
