A collapsible canopy structure is transported, via a transport vehicle, in a stowed configuration to a work location, whereupon it is demounted from the transport vehicle and re-configured to an erected configuration. A target vehicle is moved from the exterior of the canopy structure to the interior of the canopy structure; and with the target vehicle in position in the controlled environment provided by the canopy structure, the target vehicle is worked upon.
