6. The distribution of 12 spot heights with a regular 15m spacing covering a square area which is to be praded to form a horizontal plane with the height of 15m. Determine the volume to be excavated from the site. The spot height data are as follows:

What is C sub r referring to?

How do I calculate settlement for layer 1?

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.
