They can be susceptible to failure/overflowing during floods. Without them, we risk compromising the safety of future construction projects. Geotechnical Assessment IV. Ground Risk Conference: Are you Managing Risks or Taking Risks. Trial pits are commonly used to investigate shallow ground conditions to develop an understanding of the profile of soils within the ground. There will always be people who try to game the system. There can be an over-reliance from some developers on the use of trial pit soakaway testing when it is not always necessary, such as when in cohesive soils like the London Clay Formation, thus resulting in unnecessary risk. Existing and proposed Cemeteries for assessment of risk posed to environment including hydrogeological assessment. As an industry we are all aware of the fatality to a Geologist in September 2008, however, statistics of injuries, accidents or near misses are not widely known and are often only communicated internally with site staff and not shared to the wider ground investigation community. This could be delivered through a formal Banksman course or might be better delivered as task specific in-house training which should include all aspects of safe trial pitting to help create competent people who can dynamically risk assess excavations.

Some excavators can now determine depth of dig whilst excavating and perhaps providing depth markers on the excavator arm may be another alternative. Trial pits can be useful if ground is stable and can stand temporarily unsupported. strata to facilitate rough use. Find out more and contribute to one of the 5 specialist wikis. Blackburn, The principal arguments for the requirement to approach open pits is to observe the formation of the ground and groundwater in situ, accurately measure stratum boundaries, water strikes, final depth and to take photographs.
