Faced with the challenge of communicating a complex plan for maintenance of traffic, and with only two weeks before their first public meeting, contractor J.F. White turned to RDV Systems of Manchester, NH to provide a virtual model that shows not only the completed bridge, but all of the traffic routing configurations throughout the construction process. RDV came up with a very practical approach for developing a “4-D” model that shows the project changing over time.
“Traditional 4-D models usually show incremental steps of construction tied to a scheduling system and includes placement of equipment and materials. This is very laborious and quite expensive and in this case complete unnecessary. Given the short time frame and budget constraints, we focused on a single goal – communicating traffic flow changes during construction to the public.” Said Kevin Stewart, RDV’s Director of Operation for North America.
