A method of covering an opening through an exposed upwardly facing surface that defines an access opening to a conduit assembly defining a communication passage to a below surface location. The method includes the steps of: providing a cover assembly with a non-metallic component; and operatively joining the cover assembly with the conduit assembly so that the non-metallic component is placed against a metal component on the conduit assembly and transmits weight forces applied to at least one of: a) the exposed upwardly facing surface; and b) a surface defined by a cover component on the cover assembly that blocks the access opening and is substantially flush with the exposed upwardly facing surface, to the metal component on the conduit assembly.
