A complete nested vibrating-wire piezometer installation record combining subsurface conditions, graphical construction, sensor zones, filter packs and seals, cable routing, baseline readings, logger assignments, monitoring frequency, and automated validation.
IN-01 Nested VWP Installation documents a 75 ft instrumentation borehole for a riverbank-stabilization program in Cambridge, Ontario. Three Geokon 4500S vibrating-wire piezometers are installed at 20, 45, and 70 ft within individually isolated sand-filter zones.
The validation report records Passed status, 100% completeness, Good quality, an 85% confidence score, and no errors or warnings.
The first sheet documents the surface monument, upper grout and seal, and VWP-01 at 20 ft. The sensor is centred within a silica-sand filter pack and connected to the surface with shielded cable. Its initial reading is recorded in pressure and frequency units and assigned to logger channel CR6-01 / CH-1.
The second sheet continues through the deeper installation, showing VWP-02 at 45 ft and VWP-03 at 70 ft. Separate bentonite seals and cement-bentonite grout isolate the three filter zones so each transducer measures pore-water pressure at its intended depth.
Download the files individually. The XML template and completed log can be imported into WinLoG Version 6 and customized for geotechnical, environmental, infrastructure, dam, embankment, and slope-monitoring programs.
Documents sensor elevations, filter and seal zones, cable routing, baseline readings, logger assignments, and construction acceptance.
Supports long-term pore-pressure monitoring for slopes, embankments, dams, excavations, foundations, retaining structures, and riverbanks.
Provides a structured installation record for sensor serial numbers, zones, materials, cable lengths, continuity checks, datalogger connections, and completion details.
WinLoG templates can be adapted for company standards and project-specific monitoring programs. Headers, construction columns, sensor identifiers, instrument types, filter and seal zones, cable or tubing details, baseline readings, logger assignments, reading schedules, remarks, and validation rules can all be customized.
