Covering nearly three acres and stretching more than 500 feet in length, the conversion turf system at the Greater Williamsburg Sports and Events Center is the largest installation of its kind.
Following the turf padding delivery, installation began this week on the system, which is designed to transform the facility from a hardwood court to a full-size turf playing surface using large-scale mechanical components and precise engineering. The installation process will be just over a month, with the system expected to be fully installed by the end of February.

Turf Spool
When not in use, the turf is stored as a massive roll, approximately 12 feet in diameter, wrapped around a steel spool. During conversion, the turf is pulled across the wood floor by 14 hydraulic winches. Given the size and weight of the system, friction quickly became a major design challenge. Without a solution, dragging the turf directly over the wood surface would cause stretching and distort the field markings.

Below Grade Duct Vent
Engineers addressed this issue by introducing air beneath the turf, allowing it to move with minimal resistance. The system uses seven high-volume fans, each rated at 11,200 CFM, connected to an underground duct network. These ducts deliver air to 28 distribution points across the gym floor. As the turf is deployed, the fans activate in sequence, injecting controlled airflow beneath the surface so the turf effectively “floats” across the floor, similar to a large-scale air hockey table.
Once the turf is fully rolled out, the remaining trapped air is removed using a UTV and pull-behind roller, ensuring the surface sits flat and ready for play.
The result is a highly efficient conversion process that allows the facility to switch from basketball to soccer in less than one hour, maximizing flexibility without compromising surface quality.
