1.   Site Identification of the GPS Monument

     Site Name                : Dunedin
     Four Character ID        : OUS2
     Monument Inscription     : Geodetic pillar on building
     IERS DOMES Number        : 50212M002
     CDP Number               : 
     Date Installed           : 13-MAr-2000 07:00 UT

       Notes                  : 
     Additional Information   : The mark is a steel pillar bolted to the roof of
                                the bilding. The bilding foundations are of
                                reinforced concrete extending 14' (about 3m) below
                                ground level. The foundations are set on small 
                                (approx. 2m diameter) concrete rafts. The sub-surface
                                material is poorly sorted fluvial gravels but the
                                foundations are set on competent cobble within the
                                river gravels. This is known to be a relatively 
                                stable layer several other neighbouring buildings
                                have their foundations on the same geological unit.
                                There appears to be more river gravels under the 
                                coble layer with the true basement located several
                                meters deeper still. There does not appear to be
                                any marine silts or sands in this part of Dunedin.
