11:00-11:30PM: A Proven Data Fusion Strategy That Cuts Survey Costs and Field Time by 50% or More
In today’s rapidly evolving surveying industry, efficiency and cost-effectiveness are paramount. Langan Engineering has pioneered a transformative data fusion strategy, leveraging cutting-edge technologies such as the Leica Pegasus TRK mobile mapping system, RTC360 terrestrial laser scanner, drone lidar, SLAM scanning, and Cyclone 3DR software to reduce survey costs and field time by 50% or more. This presentation will delve into the practical applications and benefits of this innovative approach, showcasing real-world examples that highlight its efficiency and accuracy. A critical component of this strategy is the fusion of multiple data sets from different sources. By using the TRK to capture real-time data and employing supplementary tools like the RTC360, BLK2GO SLAM scanner and drones for infill, Langan ensures comprehensive site coverage, virtually eliminating the need for repeated field visits. This method not only cuts crew time but also accelerates the processing and extraction phases, leading to significant time savings. One notable advantage of the TRK system is its ability to deliver clean, dense data sets with high accuracy, making it preferable over UAV-based methods in many scenarios. The dual scanners of the TRK provide rich detail, allowing more accurate and efficient extraction compared to traditional drone LiDAR, which often requires additional field verification for utilities and other features. A commitment to continuous experimentation and optimization further enhances our capabilities. Langan rigorously tests systems under various conditions, pushing the limits beyond manufacturer specifications to ensure reliability and performance. This proactive approach has enabled us to confidently promise and deliver superior results. Additionally, the integration of Cyclone 3DR for data fusion has streamlined our workflow. The intuitive interface and powerful classification tools of 3DR facilitate quicker onboarding of staff and more efficient data processing. Custom scripting capabilities further enhance 3DR’s functionality, allowing Langan to tailor solutions to specific project needs, thereby increasing overall productivity. Ultimately, this proven data fusion approach not only reduces costs and field time but also enhances the quality of deliverables, positioning Langan at the forefront of the surveying industry. Attendees of this presentation will gain insights into the practical implementation of these advanced technologies and the substantial benefits they offer.

11:30-12:00PM: Virtual vs Reality a Cautionary Tale
This presentation will be a case study, walking through a virtual model with laser scanner point cloud data superimposed. It will cover tolerances and virtual issues that transition to field issues and where tolerances come into play to avoid these issues. It will start with a brief walk through the VDC Coordination process that was taken to get the team to construction. We’ll then discuss the virtual model with the point cloud data overlaying it. We’ll explore some of the issues that we were able to resolve with the point cloud. Finally, we’ll address where the point cloud data deviates from the virtual model, what’s important to pay attention to, and what can be ignored. The presentation’s conclusion will address the use of laser scanning as a QA/QC for the VDC Coordination/Installation process on a live project and the benefits of scheduling a laser scan and follow-up model walk for construction projects.
