RCA Australia environmental section has recently undertaken targeted site investigations for Hunter Development Corporation (HDC) on the former steelworks site as part of Stage 2 works to determine specific locations of contaminated soils and underground structures. The work was undertaken with the aid of old BHP drawings, site knowledge of former activities and structures, using CAD to determine GPS co-ordinates, followed by test pitting on site.
These investigations were to provide additional information that had not been gathered during the original investigations undertaken by BHP prior to closure and demolition. This information will assist the civil contractor to plan site activities during contouring works which will commence shortly.
