Heritage Surveying with Surveybase

Author: Curtis Woodward

Surveybase has been a leading provider of precision digital surveying services across the UK for over 25 years, known for its comprehensive services, including Topographical, Measured Building, 3D Laser Scanning, 3D BIM Modelling, Underground Utility, and UAV Drone Surveys. With a long-standing reputation for delivering accurate and dependable surveys, Surveybase supports clients in the architecture, engineering, and construction (AEC) industries. Their commitment to cutting-edge technology and a client-focused approach ensures the delivery of bespoke services tailored to the unique requirements of commercial, residential, heritage, and infrastructure projects.

Surveybase continuously elevates its services through strategic investments in cutting-edge equipment and the growth of its expert surveying team. A key contributor to this success is its partnership with Leica Geosystems, part of Hexagon, whose advanced technology plays a vital role in maintaining Surveybase’s industry-leading standards.

Project Overview: Caernarfon Castle

Caernarfon Castle, a UNESCO World Heritage Site, stands as one of Wales’ most iconic medieval fortresses. Originally constructed as a motte-and-bailey by the Normans in the 11th century, it was reimagined and rebuilt in 1283 under King Edward I, transforming it into the grand stone stronghold seen today.

Surveybase conducted a measured building survey of Caernarfon Castle, utilising advanced 3D laser scanning technology to create an accurate and detailed digital representation of the historic structure. By capturing millions of data points, the survey accurately mapped the castle’s intricate architectural features. This point cloud data served as the foundation for a comprehensive heritage level 3D BIM model, ensuring every detail was meticulously documented to support restoration, preservation, and future planning efforts.

Challenges and Solution

Surveying Caernarfon Castle presented several challenges, including its complex architecture, access restrictions, and the sensitivity of preservation efforts. The tight, circular design of the spiral staircases further complicated traditional surveying methods. To overcome these obstacles, Surveybase utilised the Leica RTC360 3D Laser Scanner in combination with Leica Cyclone software. This powerful combination allowed for the precise capture of intricate details, ensuring a more accurate and efficient survey of the entire site.

Surveybase were early adopters of the RTC360 and now operate a fleet of scanners across their survey teams. The decision to integrate the RTC360 with Leica Cyclone registration software was driven by the need for faster, more accurate data capture in surveying and construction. Its high-speed 3D scanning capabilities and minimal disruption made it ideal for complex projects like Caernarfon Castle, where precision and detail were essential. The RTC360’s rapid point cloud generation, portability, and automated in-field registration set a new benchmark for delivering reliable, high-quality survey data in record time.

Outcomes and Benefits

The initial reaction to the RTC360 was overwhelmingly positive. The team was impressed with its ability to capture high-quality 3D data quickly and efficiently, especially in challenging environments. The automatic point cloud registration feature significantly reduced time spent on data processing, allowing for faster project turnaround. The scanner’s ease of use, portability, and high accuracy exceeded expectations, quickly becoming a valuable tool for improving efficiency in surveying processes.

“Surveying Caernarfon Castle presented unique challenges, but with the Leica RTC360 and Cyclone software, we were able to tackle them effectively. The scanner’s fast data capture and automatic organisation allowed us to reduce on-site time while ensuring the precision needed for this historic site.”
