PSS was contracted by AbiGroup to assist in reinstating the state control network disturbed by construction of the Hunter Expressway.
Under liaison with Land and Property Information (LPI) and Roads & Maritime Services (RMS), PSS designed a survey to meet the standard of the LPI for the 32 new permanent marks to be recorded in the Survey Control Information Management System (SCIMS).
PSS were responsible for overall survey design and methodology for both levelling and a GNSS network over the 27km project scope.
AbiGroup completed all levelling survey work based on PSS survey design, while PSS performed all GNSS work including a preliminary network adjustment for submission to LPI.
