REMARKS:1. Excavated to 1.5m to check for utilities. Further drilling through a PVC liner installed in excavation2. During the installation of the standpipe piezometer 30 bags of backfill material (filter sand and gravel) were required for a 4.40m deepinstallation. This indicates the presence of a large void within the zone of the standpipe piezometer installation.

REMARKS:1) Ground Access Portal (GAP) service clearance to a maximum of 1.80m, drilling commenced from 1.6m.2) Inclined hole, azimuth at 122° and inclined at 60°, measured from horizontal; inclination confirmed by core orientation tool.3) Length is length along core, NOT depth below ground level.4) Stratigraphic and discontinuity angles are apparent angles NOT true angles.5) Water level readings measured along drillhole axis at 60° inclination, then converted to depth bgl.6) Core has been oriented between 23.9m and 37.8m using Reflex ACT3 (SN:3360). The scribe line on the core indicates the bottom of hole.

REMARKS:1) Ground access portal (GAP) service clearance to 1.68m bgl, after installation drilling commenced from 1.5m bgl.2) Between 1.5 & 10.2m, the high level of core loss was caused due to the core's greasiness, which resulted in it unable to stay within thefingers of the catcher while it was not breaking off the base of the hole. Multiple attempts were undertaken to recover the core "stick-up" butthe core was washed away with each attempt to redrill.
