Virtual Construction

Avoid field problems using digital models

More and more construction teams are using virtual construction to identify potential field problems before they become reality. By using computer tools to build digitally before building physically, designers and builders can identify conflicts between piping, framing and other building components, plus identify scheduling and staging issues.

Virtual construction has been around in various forms for years, but recent software advances are making the practice more commonplace. Some of the early forays were in the 1970s, when nuclear power plant designers developed 3D models of facilities in various stages, introducing a fourth dimension: time. 4D CAD gained a foothold in various building projects in the late 1990s as PC-based CAD became more sophisticated and affordable. The transportation and infrastructure sector has been a bit slower to adopt virtual construction techniques, but that, too, may be changing, industry experts say. Read More >>

Spatial Tech: Animating Geospatial Data

By James L. Sipes

Animation is an illusion. You display a series of still images in rapid succession, and the illusion is that you have captured the dynamic nature of an object or scene. GIS professionals have long been interested in displaying dynamic changes that occur over time to geospatial information. One reason is to present information in a format that is exciting and easy to understand. Another is that animating geospatial information reveals patterns in the landscape that may be invisible when studying static images.Read more >>
