About Heritage Survey
The national heritage architecture represents the cultural identity of a country and its society; therefore, it is of fundamental importance to be maintained, preserved, and restored. Our specialised Heritage team is producing accurate historic surveys and documentation with a scientific approach. We utilise the latest digital technologies for surveying to obtain virtual reproductions at various scales with impressive high accuracy. All survey techniques that we put in place are non-intrusive and calibrated for the documentation of fragile historic features.
Building Pathology Inspection
Every project and development on a listed building or a listed urban area needs highly detailed and especially accurate approach. We offer building pathology services that help identify defects, decays and other fragilities through non-intrusive methods and techniques.

Purpose of the Heritage Building Survey
- Planning and Development: Every project and development involving a listed building or within a listed urban area requires accurate historic documentation before reviewing planning schemes and local heritage registers.
- Understanding Historic Layers: Historic buildings often have complex architectural histories. A digital 3D heritage survey helps uncover construction techniques and historical phases, identifying structural elements and their relationships over time.
- Updating Incomplete Records: Existing drawings of historic buildings are often missing, partial, or outdated. Updated documentation is essential for planning purposes.
- Detailed Documentation: Detailed 2D drawings at scales like 1:20/1:10 and Orthophotos are necessary for assessing damage and decay in elements like stonework, bricks, tiles, and architectural features.
- Structural Analysis: Historic buildings may require structural analysis, including monitoring deformations and checking the verticality of walls.
- Component Restoration: Accurate surveys and detailed documentation are crucial when disassembling and rebuilding historic architectural features during restoration.
- Accessibility and Virtual Tours: A digital 3D heritage survey is essential for historic sites not accessible to the public. It enables exploration through Matterport virtual tours and 3D environments like textured models and coloured point clouds.
- Interactive Information: Virtual reality and 3D models from scan data support interactive databases. They enable features like virtual educational tours in museums, linking artwork to descriptive content such as text, images, videos, etc.
- 3D Printing: Meshed 3D models from scan data are required for 3D printing scaled reproductions of statues, stonework, and historical features.
Our heritage survey approach
- Initial Understanding: Historic buildings are unique and require thorough comprehension before any work begins. We start with preliminary research into a building’s historical records to plan survey activities, define the scope, and identify the areas that need investigation.
- Specialised On-Site Surveys: Our specialised team conducts on-site heritage surveys using advanced non-intrusive methodologies, including laser scanning, photogrammetry, total station, GPS, drones, and high-resolution cameras.
- Expert Data Processing: Back at the office, our data processing team utilises cutting-edge software and high expertise to process the collected data, ensuring accuracy and precision.
- Comprehensive Deliverables: We provide accurate and detailed outputs, including 2D CAD drawings, 3D CAD or Revit models, mesh models, and high-resolution orthorectified images, all tailored to various scales of representation.
- Conservation Documentation: Our services extend to conservation documentation, encompassing decay mapping and damage analysis for various materials, helping preserve heritage structures effectively.
- Client-Centric Deliverables: Deliverables are customised based on the client’s specific requirements and are produced in accordance with the standards outlined in Historic England’s guidelines.

Our heritage servey services and deliverables
3D Laser Scanning Survey for Heritage architecture
We excel in delivering Point Cloud for Heritage Projects, employing latest 3D laser scanners to capture exceptionally precise data, with an accuracy of up to 2mm point precision. Point clouds can be obtained in either greyscale or vibrant colour, providing flexibility to suit project requirements. Our deliverables come in a range of formats, including FLS, E57, RCP, PTS, and PTX, ensuring compatibility with various software and enabling seamless integration into your heritage conservation and documentation efforts.
Detailed 2D drawings for heritage architecture
We deliver various types of highly detailed 2D CAD drawings at scales of 1:20/1:10. With a representation tolerance of approximately 2mm, these drawings offer the precision necessary to distinguish every individual feature that contributes to the historical architecture. These detailed 2D drawings play a fundamental role in supporting various documentation and analysis needs, including assessing the state of preservation and mapping damage and decay in heritage materials.
High resolution orthophoto for heritage architecture
Orthophoto at scale 1:20/1:10 is the indispensable graphic work to define in true dimension the decoration system of a historic building’s facade, or its wall texture and stone works. This process takes place through the production of a high-resolution photo collage of close-up portions of the façade, calibrated, through image editing software, over the orthometric view of the point cloud . A high-resolution Orthophoto can also be produced directly from a point cloud when the laser scans are produced in true colours.
Decay mapping and Damage Analysis
Decay mapping and damage analysis for various materials
Our specialised team conducts precise surveys and analyses damage and decay in various materials like plaster, stone, bricks, and wood. We achieve this by interpreting high-resolution Orthophotos of historical surfaces, identifying materials and their condition. Areas showing decay are marked with coloured hatches in CAD (linked to a decay key list) and overlaid onto detailed 2D drawings at a 1:20 scale, representing textured stone works and walls. This deliverable provides an accurate map and description of each stone and its condition.
3D CAD & Revit Models
3D CAD & Revit models for heritage architecture
3D models of historic buildings must be distinguished by the accuracy in modelling decorative details such as carved cornices, columns heads and bas-reliefs. Our laser scanner technology allows the acquisition of extremely high density of point clouds, offering accurate digital data to be modelled in CAD or Revit at various LOD.
3D Mesh Models
3D Mesh models for complex architectural features
Some historic features such as decorative details and statues are too complex to be defined with 3D solids and 3D surfaces using softwares like CAD or Revit. A 3D Mesh produced, as a part of heritage survey, from scan data ensures to maintain the most realistic tridimensional representation and can be textured and integrated in CAD or Revit models.
Archaeological survey & documentation
Archeological sites always need an accurate heritage survey and documentation for the interpretation of portions and ruins of ancient buildings and excavations. The coloured point cloud produced through a laser scanner survey, integrated with a topographical survey by Total Station and GPS measurements, is the only essential support to define the morphology of the site and carry out archeological investigations.
3D Laser Scanning Survey for Heritage architecture
To ensure highly accurate results for the production of point clouds, 2D drawings and 3D models, our specialist heritage team use latest 3D laser scanners and surveying equipment from leading brands such as FARO & Leica.
