QUESTION FOUR Geophysical surveying is a means of filling data on strata changes between widely spaced boreholes. On large sites geophysical methods can show economies due to the rapidity with which extensive areas can be covered. Geophysical methods are best suited to deep investigations of in rock strata, for examples dams or tunnels where the stratification of rocks at depth is required, and for investigations in soils containing many cobbles or boulders where probings or cone tests ara impracticable. Describe the following geophysical methods of investigations: (i) Electrical resistivity (ii) (iii) Magnetic (iv) Seismic refraction and reflection Gravimetric (v) Side scan sonars (vi) Borehole logging (vii) Ground radar

Q1. Table Q1 shows the levelling data obtained from field observations between two temporary benchmarks namely TBM 1 and TBM 2, respectively. Where, the total levelling distance between TBM 1 and TBM 2 is 250 metres. As a junior site civil engineer at the construction site, you have been assigned by a senior site civil engineer to finalise and evaluate the levelling data to ensure the levelling work complies with the levelling standard and procedures.
