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.
