Abstract: A modular foundation system is provided which comprises a base structure defining a cabling void, and a raising frame element connected or connectable to an upper portion of the base structure, the raising frame comprising an adapter coupling. An electric-vehicle-charger adapter plate is then provided having a cabling aperture therethrough. The electric-vehicle-charger adapter plate is releasably engagable with the adapter coupling to provide a foundation for an electric vehicle charger once installed. A blanking cover releasably engagable with the adapter covering is also provided, the electric-vehicle charger adapter plate and blanking cover being selectably interchangeable.

Abstract: A detector access chamber (10) for a wireless directional detector (40), comprises a hollow body (12) having an open a upper end (20) and a lower end (24) at an opposing end, a lid (16) engageable with the open upper end (20) of the body (12) and preferably adapted to accommodate at least a 40 tonne vehicular load, and a detector holder (38) within the body (12) to hold a wireless directional detector (40). In use, the lid (16) and the detector holder (38) together define a volume adapted to constrain internal reorientation of the wireless directional detector (40) caused by vibrations. A submergible detector system (42) is also provided.
