The Advancements in Preconstruction with Gaussian Splatting

Technology is advancing every day, creating new opportunities for innovation across the construction industry. With each advancement, preconstruction is starting to adapt and evolve in ways we might not have thought possible. This change will bring in new opportunities for future workers and shareholders alike.  

Gaussian Splatting, also known as “Splat,” is a new kind of technology that creates highly detailed 3D models using photos and videos. After being uploaded and sent to offline VDC Computers for processing, the photos and videos will return in the form of a high-detailed 3D model. This capability is helping teams quickly visualize existing conditions, gather accurate measurements and make informed decisions earlier in the project lifecycle. 

The video below shows how our Weitz Colorado team is leveraging this technology on our Colorado School of Mines Resident Hall VII project. Our teams around the globe have been exploring this new technology to enhance jobsites. 

Turning Photos into Precision Models  

In December 2024, the team on a Confidential Data Center project in Mexico used Splat to determine where anchor bolts should be placed. At the time of this project, laser scanning was the go-to method for creating detailed models of buildings being made. However, this technology was not readily available to the team. To overcome this challenge, the team took photos and videos using their mobile devices, including a measuring tape within the shots to provide scaling reference points.  

These images were processed using Gaussian Splatting to generate a detailed 3D model of the area. The utilization of Splat helped reduce hours of manual measuring and helped the team finish their objectives on schedule.  

Keeping Safety in Mind  

At Weitz, safety is always top priority. Gaussian Splatting is also helping teams plan work more safely by improving site visibility and identifying potential hazards before work begins. On a recent warehouse project, the team needed to maneuver equipment near overhead powerlines. Powerlines are often the most challenging structures to maneuver around, especially when operating cranes. While areas can be marked to indicate safe distances, heavy machinery still faces risks when maneuvering around tight spaces. To address this, a VDC team member captured drone footage of the entire warehouse area, including surrounding powerlines. After processing, the team received a detailed 3D model of the site with the powerlines clearly outlined. This enhanced image allowed the team to maneuver the warehouse crane and other equipment around the powerlines with greater confidence, improving safety and efficiency during operations. 

A New Tool for the Future of Preconstruction 

Gaussian Splatting is quickly becoming a valuable tool in preconstruction. By transforming simple photos and videos into large-scale, high-detailed 3D models, teams can improve planning, reduce field time and enhance safety. This advancement in technology will continue to open doors for future projects and methods of construction.
