The Leica Pegasus:Backpack captures data efficiently and cost effectively, to document the changing building construction sites for progressive scanning by providing 4D (time), 5D (cost) and 6D (performance) elements for full lifecycle BIM documentation. It assists 4D scheduling by providing a regular, fast, and efficient connection to the chaotic construction site, enabling milestone monitoring and building changes to be easily documented in 3D data and imagery. 5D payment 
approval is as simple as reviewing the point cloud and images for a visual validation of completed work. In 6D building information modeling (BIM) reality capture, offers the opportunity to pass on to the new building owner complete as-built 3D drawings, 2D elevations, floor plans, and fly-throughs, including the time synched imagery on a hard drive or in the cloud.
As virtual reality (VR) becomes increasingly embedded in our society, the ability to quickly capture rich 3D data with a versatile, wearable reality capture solution will become increasingly important. Combined with Autodesk, Intergraph and other software interfaces, datasets supplied by the Leica Pegasus:Backpack will add timeliness and accuracy to virtual reality environments in construction. Stakeholders can have 24/7 access to an immersive as-built. The benefits will be recognized not only by the construction team during the build, but by facilities managers who will depend on the captured information for decades into the lifecycle of the building.
