Hellier Services
Our Founder
Over 27 Years of Leadership in 3D Laser Scanning and Digital Facility Documentation
David Hellier, Founder of Hellier Services, brings extensive experience in 3D laser scanning, digital documentation, and advanced facility visualization technologies. His involvement dates back to the early development and commercial adoption of 3D laser scanning technology, including his work with INOVX Solutions, a pioneer in applying three-dimensional data capture and modeling solutions to industrial facilities.
Throughout his career, David has participated in hundreds of 3D documentation projects across a diverse range of industries, including oil and gas, petrochemical, manufacturing, power generation, and industrial infrastructure. His experience encompasses the application of laser scanning, intelligent 3D modeling, as-built documentation, and digital visualization to support engineering, construction, maintenance, facility modifications, and asset management.
As an early adopter and longtime advocate of 3D technologies, David has witnessed the industry's evolution from traditional point-cloud capture and standalone 3D models to today's sophisticated reality capture platforms, digital twins, and integrated facility information management systems.
He has consistently promoted the value of accurate, accessible, and reusable 3D data throughout the entire facility life cycle—from initial design and construction through operations, maintenance, modernization, and eventual decommissioning.
Through Hellier Services, David continues to champion practical, cost-effective applications of modern 3D documentation technologies, helping facility owners, engineers, and project teams improve collaboration, reduce field verification requirements, minimize project risks, and make better-informed decisions.
His guiding philosophy is that 3D documentation should be more than a snapshot of existing conditions—it should be a long-term digital asset that continues to deliver value throughout the operational life of a facility.
MobilE scanning Technology
NavVis VLX
VLX is a SLAM-based mobile mapping system developed by Navvis, a company specializing in indoor mapping and positioning solutions. The Navvis VLX system uses LiDAR and camera sensors to capture data as it moves through an environment, allowing for the creation of highly accurate and detailed 3D maps.
The system is designed to be used in a variety of industries, including architecture, engineering, construction, and facility management. The Navvis VLX is able to capture up to 300,000 points per second, allowing for fast and efficient mapping of large indoor spaces.
The Navvis VLX system utilizes advanced SLAM algorithms to accurately track the device's position and orientation as it moves through the environment. The system uses a combination of visual and inertial odometry, as well as loop closure detection, to ensure accurate positioning and mapping.
One of the key features of the Navvis VLX system is its ability to capture both geometric and semantic information about the environment. This allows for the creation of highly detailed and accurate maps that can be used for a wide range of applications, including indoor/outdoor navigation, facility management, and facility design.
Overall, the Navvis VLX system is a powerful example of how SLAM technology can be used to create highly accurate and detailed maps of environments. The system's advanced algorithms and sensors enable it to capture a wealth of information about the environment, making it a valuable tool for a wide range of applications.
Facility Relocation Using 3D Technology
3D scanning is a crucial tool for facility relocation, providing millimeter-level accurate digital documentation that allows for detailed pre-planning, minimizes unexpected issues, and significantly reduces downtime and costs. It replaces time-consuming and error-prone manual measurement methods.
