(b) The data from a levelling survey are shown in Table Q2. Using the rise and fall method, calculate levelling measurement from TBM1 to TBM2 (i) Calculate all reduce level and perform arithmetic checks to support your answer. (ii) Plot the long section profile along the chainage .

What are the different methods used for soil classification? Dont use chatgpt or other ai tools. If incase i fine ai content i will give you a dislike.

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.

SITUATION 3. a) The base and altitude of a triangle lot were measured to have certain probable errors of 314.60 0.16 and 92.60 = 0.14, compute the probable error of the resulting computation. (3- b) The following sides of a rectangle and its probable errors are 120.40 0.04 and 360.50 ± 0.08 respectively. Compute the probable errors of the sum of the sides (perimeter) of rectangle. (3r c) The probable error of the mean of 6 observation is 0.043 and the most probable value of the measurement is 860 m compute the relative precision. C
