New Zealand Construction Firm Proform Group Achieves Photorealistic 3DGS Models of Historic Structures with XGRIDS K1

Proform Group Ltd., a leading construction and renovation specialist in New Zealand, has pioneered the adoption of cutting-edge 3D mapping technology to revolutionize their approach to historic building renovation. By implementing XGRIDS' LixelKity K1 handheld scanner on their Mendoza Terraces Remediation Project, Proform Group has found a new way to combine centimeter-level accuracy, stunning visualization, and client transparency while working on earthquake strengthening of the historic Ford Wall.

This case study examines how Proform Group's early adoption of Gaussian Splatting technology is setting new standards for precision and visualization in heritage conservation projects.

Customer Profile

Company: Proform Group Ltd.

Industry: Construction, Renovation, Heritage Conservation

Location: New Zealand

Key Project: Mendoza Terraces Remediation Project, including earthquake strengthening of the historic Ford Wall

Project Details: $3.4 Million

Partner: Brosnan Construction

Challenges

Proform Group faced several significant challenges in their heritage renovation work:

  1. Documentation Precision: Historic structures like the Ford Wall require accurate documentation to ensure appropriate preservation techniques.
  2. Site Accessibility: Extensive scaffolding made traditional tripod-based scanning methods impractical.
  3. Flexible Documentation: The team needed a solution that didn't require constant subscription payments for occasional use.
  4. Stakeholder Communication: Communicating complex structural details and renovation progress to clients often led to misunderstandings and approval delays.

Solution: 3D Scanning Heritage Buildings

Proform Group became the first company in New Zealand to deploy the XGRIDS LixelKity K1 handheld scanner, integrating it into their existing documentation workflow:

Technology Components

  • Hardware: XGRIDS LixelKity K1 Compact Handheld Scanner
  • Software: XGRIDS Lixel CyberColor for 3D Gaussian Splatting model generation, LixelStudio for point cloud processing
  • Key Technology: Multi-SLAM algorithms combined with Gaussian Splatting
  • Integration: Complementing existing 360° cameras and drone photogrammetry

Implementation Process

As  Project Managers with trade backgrounds rather than engineers, Proform Group needed scanning solutions that prioritized practical usability over ultra-precise engineering measurements. They had previously relied on rented Trimble and Faro equipment but sought more cost-effective alternatives for their occasional documentation needs.

Daniel Manchester, Senior Project Manager and UAV Operations Manager at Proform, discovered XGRIDS through LinkedIn and was immediately attracted to the SLAM lidar capabilities allowing faster site capture. The Gaussian Splatting visualization technology particularly caught his attention with its remarkable realism.

Implementation proved surprisingly straightforward, with Daniel describing the system as nearly "plug and play" with minimal training required. Their workflow integrated the XGRIDS software ecosystem, primarily using LCC for Gaussian Splat processing and LixelStudio for point cloud work, occasionally supplemented by Cloud Compare for specific editing tasks.

Results and Impact

The implementation of XGRIDS technology has delivered substantial benefits across multiple areas:

Practical Benefits

  • Simplified Capture Process: The K1's handheld nature proved invaluable in navigating the complex scaffolding at the Mendoza Terraces site. Where traditional tripod scanning would have been prohibitively time-consuming, the team simply walked through the site twice to ensure comprehensive coverage.
  • Suitable Accuracy Level: The centimeter-level accuracy perfectly matched their construction management needs without overengineering. This balance of precision and practicality allowed them to capture measurements while maintaining workflow efficiency.
  • Flexible Cost Structure: Teams can reap the benefits of simple scanning workflows and full ownership of their 3D assets. K1 is a field-ready, single-operator hardware solution, while the LCC software offers flexible licensing options. For a team that uses 3D documentation occasionally rather than daily, this approach allowed them to access and process data without a hefty investment.

Visualization Impact

The most remarkable outcome has been the photorealistic quality of the 3D models generated through Gaussian Splatting. Stakeholders frequently mistake the digital models for video footage, with their initial reaction often being surprise upon learning they're viewing a 3D model rather than a recording.

Daniel discovered that while the visual fidelity impressed viewers, the real value emerged when stakeholders could actively manipulate the models. As he notes:

"Being able to actually manipulate the model and highlight or showcase the exact part that you want to show—that's where the modeling was brilliant."

This interactive capability transformed technical discussions and enabled more informed decision-making among all project stakeholders.

Heritage Conservation Applications

Proform Group's work has attracted significant interest from Heritage New Zealand Pouhere Taonga, the government organization overseeing historically significant sites.

The K1 unlocked two key advantages for conservation:

  1. The ability to quickly document restricted-access interiors that are closed to the public
  2. Creating comprehensive visual records equivalent to "thousands of photos" in a single scan

Building on their success, Proform Group is actively exploring broader applications in heritage conservation. They've already volunteered time on heritage documentation projects to demonstrate the technology's capabilities to conservation authorities. A test deployment at the Ng King Brothers Chinese market garden settlement site demonstrated particular value for heritage documentation.

This proactive approach showcases their commitment to advancing documentation standards in New Zealand's heritage sector and positions Proform Group as innovation leaders in this specialized field.

Building on their success with the Mendoza Terraces project, Proform Group envisions an expansion to their use of XGRIDS technology:

  • Digital Twin Creation: Developing interactive models for ongoing building management
  • Preventative Maintenance: Using high-precision models to detect early signs of structural issues
  • Training Applications: Creating immersive learning environments for heritage conservation techniques
  • Virtual Tourism: Exploring opportunities to share completed models of historic structures with the public

Client Testimonial

"The level of detail and realism in the 3DGS models produced by Proform Group using the XGRIDS technology has completely transformed how we understand our projects. Being able to virtually walk through them, gives us confidence that precise and accurate records are being undertaken. This technology has made complex planning and monitoring accessible and clear."

Conclusion: Setting New Industry Standards

Proform Group's implementation of XGRIDS technology represents a significant shift in how heritage renovation projects can be documented and visualized. By achieving a level of detail and realism previously unavailable with conventional methods, they have:

  1. Enhanced documentation capabilities without requiring specialized expertise
  2. Provided novel visualization for historically significant structures
  3. Created a flexible workflow that accommodates their occasional but vital 3D documentation needs
  4. Pioneered applications that are already attracting interest from heritage conservation authorities, and designers.

As the first company in New Zealand to adopt this technology, Proform Group has positioned themselves at the forefront of construction innovation, demonstrating how cutting-edge 3DGS modeling can solve real-world challenges in complex renovation projects.
