The more two people communicate, the more opportunity there is for a misunderstanding. So to get beyond the limits of human communication, Sundt brought the speed and precision of digital connectivity to the jobsite. This resulted in large-scale time reductions while laying out the 26,000 reference markers for concrete work at the San Diego International Airport’s Rental Car Center.
In a traditional survey method, two-person survey teams would measure each point with tape measure and string in a process that normally would take ten workers at least one year to complete. We determined through research that the two-person teams communicated 12 times for every completed reference point. That meant the teams would need to communicate 305,500 times during the entire project, causing time delays and possibilities for error. So Sundt developed a way to cut the workload by 70 percent and improve the project’s quality. We completed the layout with only five crew members in the same amount of time, while vastly improving the project’s quality.
Using virtual design and construction model-based data to populate information in a robotic total station, surveyors loaded in the exact alignment created by the designers. Using very accurate, coordinated data directly from the model, we digitally replicated the data on the jobsite. This accelerated both installation speed and accuracy beyond the previous standards. This not only saved work hours, because crews didn’t spend valuable time communicating and manually measuring, but also reduced the possibility of human error due to direct data import – all at no added expense.
