Field logging templates

a series of proforma sheets available for download:

Sample Description only

For systematic description of a series of samples such as those from a borehole. This sheet can also be used to record the description of any other ad hoc sampling exercise. Sample description with stratum description For the systematic description of borehole samples and which includes space to record the stratum boundaries and the descriptions of the strata. This format is very useful for field use but does provide less space for the sample descriptions than the previous sheet.

Extruded undisturbed sample description

For use when carrying out extrusion and splitting of samples for detailed recording of fabric features. This is most commonly carried out in detailed investigations of recent normally consolidated soils, but the format can be used on any core sample of up to 1 m in length.

Core description

For use when describing continuous rotary cores of soil or rock including the material and mass features such as the discontinuities and fracture indices.
Download

Borehole discontinuity log

For use when recording detail on each discontinuity within a core and when the requirement is to record all available information on each fracture in turn. This amount of information does not readily fit onto a core description sheet, or onto a normal field log and so this information is tabulated and entered into the field records as a table. These records can be readily typed into a spreadsheet for transmission as data.

Trial pit log

For recording the soil or rock exposed in trial pits or short trenches. Long trenches will require a rather larger sheet of paper. The boxes available on this form include those for recording samples and field tests carried out in situ. This form can also be used for mapping horizontal surfaces such as foundation excavations or trench bases exposed during the course of the construction works.

Scan line log

For use in the systematic recording of fractures on scan lines set up in the field. This sheet is similar to the borehole discontinuity log but has additional columns owing to the extra information that is available for recording in a field exposure.
Download

Exposure log

For use in ad hoc exposures or excavations such as may typically be found in exposures during construction works.
Download

Tunnel face log

An adaptation of several of the other sheets suitable for use in a machine or hand bored circular section tunnel. The shape of the face is readily adjusted for other profiles. This is the sort of sheet that can often sensibly be laminated for use underground.
