A new approach to on-site visualization brings design information to life.

“I tell people it’s not much more than a phone,” said Mark Lawton, chief engineering surveyor for Skanska UK, about Trimble SiteVision. “It’s a small, easy and friendly way to show people what is happening.”

Lawton and Skanska used SiteVision on a major upgrade to England’s A14 motorway. Comprising 34-km of road improvements, the work includes 70 structures, a 750-meter long bridge and a 19-km bypass around the town of Huntingdon. Project contractor Skanska UK is using SiteVision to provide real-time, in-field visualization of the new routes and structures for local residents and landowners as well as construction teams.

A fast, friendly way to use augmented reality to share graphical information in the field, Trimble SiteVision combines design and GIS data with precise positioning and real-time, on-site images to provide accurate visualization of projects and assets. It’s an ideal tool for working both with professional and non-technical stakeholders.

Lawton used SiteVision to discuss the project impact and benefits with people not familiar with highway construction. Because many stakeholders found it difficult to understand the project based on conventional highway design plan sheets Lawton turned to the SiteVision outdoor augmented reality solution. Running on a user-supplied Android®-based smartphone, and coupled with high accuracy Trimble Catalyst™ GNSS positioning, SiteVision provided real-time, on-site visualization of the project’s planned roadways, structures and construction zones.

SiteVision can use 3D models and information from a wide array of sources including CAD and engineering design packages, BIM and GIS. Using Trimble Catalyst GNSS positioning, SiteVision can depict its models with accuracy of a few centimeters. It can be used for verification of models and data sets and for checking construction progress and as-built information.

The SiteVision system made it easy for people to understand and visualize the plans, Lawton explained. “When we go out to site with SiteVision, people say "Right, we understand it now. We get the picture." Lawton also used SiteVision in working with construction teams to plan the work; the system’s data integration and precise GNSS positioning provided real-time visuals for fencing, excavation limits, construction material laydown areas and work yards. “My goal is to connect decision makers with accurate information,” Lawton said. “I see Trimble SiteVision as a way of providing information that any user can understand.”

SiteVision also brings immediate value and efficiency in depicting the location of underground utility cables and pipelines—an important safety consideration in nearly any project. By linking to precise utility location information, SiteVision can help utilities and contractors increase accuracy and reduce time and cost in locating and protecting buried assets.
