Site Identification of the GNSS Monument Site Name : Wellington Airport Four Character ID : WGTN Monument Inscription : IERS DOMES Number : 50208M003 CDP Number : Monument Description : PILLAR Height of the Monument : 0.69 Monument Foundation : Monument construction. A hole was dug through : a thin layer of soil and into weathered : greywacke outcrop. A reinforced concrete pad : was built on the greywack surface, with a 70 : cm high reinforced concrete pillar above the : pad. The pad was not attached to the : underlying rock except by gravity and the : binding of the concrete to the rock. This : monument is therefore likely to be less stable : in the event of an earthquake than later : monument installations in New Zealand. In the : absence of strong ground shaking there is no : concern about monument stability. Foundation Depth : About 0.3 m to bottom of concrete. Marker Description : 5/8 inch thread in centre of 150 mm diameter : stainless steel plate set horizontally in top : of approx. 400 mm diameter concrete pillar. Date Installed : 1996-05-17 Geologic Characteristic : Solid greywacke outcrop. Bedrock Type : Greywacke. Bedrock Condition : Good. Fracture Spacing : Fault zones nearby : Yes. Distance/activity : Additional Information : 2.
