HKA G&S: reshaping engineering and surveying with 3D scanning

Overview

The rapid evolution of 3D scanning technologies is fundamentally transforming how construction professionals and surveyors approach complex workflows—from BIM as-built documentation to manhole inspections, heritage conservation, and addition and alteration projects. This webinar will delve into real-world applications where 3D scanning has overcome traditional challenges, including accuracy gaps in manual measurements for intricate structures, time-intensive processes for large-scale site documentation, safety risks associated with accessing confined or hazardous spaces.

Speakers will explore how advanced tools like 3D Gaussian Splatting (3DGS) and visual Simultaneous Localisation and Mapping (SLAM) are pushing boundaries further. For instance, 3DGS enables ultra-high-resolution point clouds for precise BIM integration, even in low-light or GPS-denied environments. SLAM-powered mobile scanners streamline on-site data capture, allowing engineers to generate actionable models in real time during inspections. Case studies will illustrate these innovations in practice, such as using scanning solutions to accelerate railway tunnel assessments with millimetre-accurate deformation monitoring, simplify utility mapping in urban redevelopment projects, and preserve historical buildings through non-invasive digital twins.

The session will emphasise interdisciplinary collaboration, demonstrating how surveyors, engineers, and other construction professionals can align workflows to optimise project delivery. Participants will learn more about how to select the right technologies for their workflow, balancing cost-efficiency with technical requirements.
