Site Identification of the GNSS Monument Site Name : Whangaparaoa No 3 Four Character ID : AUCK Monument Inscription : none IERS DOMES Number : 50209M001 CDP Number : none Monument Description : CONCRETE PILLAR Height of the Monument : 1.3 m Monument Foundation : REINFORCED CONCRETE BLOCK Foundation Depth : 1.2 m Marker Description : STAINLESS STEEL PLATE Date Installed : 1995-09-18T00:00Z Geologic Characteristic : Sandstone/mudstone Bedrock Type : SEDIMENTARY Bedrock Condition : WEATHERED Fracture Spacing : unknown Fault zones nearby : NO Distance/activity : Additional Information : The site is in an area of early Miocene : (Waitemata group) sandstone and mudstone strata : with occasional volcaniclastic debris flows : (Parnell grit). The strata are superficially : folded. Basement is Jurassic greywacke at : about 200-300 m depth. : Monument construction. A hole was augered : through clayey soil to refusal at about 1.2 m : depth in compact sediments, and was widened at : the bottom by spade. A small amount of : concrete was placed at the bottom, then a 2.4 m : long by 30 cm O.D. concrete tube was placed : vertically in the hole. Three or four lengths : of reinforcing bar bent over at their bottom : end were placed inside the yube. Concrete was : poured to fill the hole external to the tube, : and the inside of the tube. A 15 cm diameter : stainless plate with protruding 5/8"-11 screw : was set exactly horizontal in the top of the : concrete. Height of pillar above pad is 1.27 m : to top corner of pillar, 1.28 m to the level of : the stainless plate. The top concrete surface : of the pillar was deliberately made uneven to : reduce resonance effects between the top of the : pillar and the antenna. The surface of the : stainless plate serves as the height reference : point. 2.
