Here are the calculations for B.T./N.B.T.: Step 1: Calculate the total fall over the trench length. The grade is 1.65\%, and the trench length is 4.85\, m. Fall = (1.65)/(100) × 4.85\, m Fall = 0.0165 × 4.85\, m Fall = 0.079025\, m Step 2: Calculate the Invert Level (I.L.) at the end of the trench. The starting Invert Level (I.L.) at Connection Point "A" is 12.049\, m. I.L. at end = Starting I.L. - Fall I.L. at end = 12.049\, m - 0.079025\, m I.L. at end = 11.969975\, m Rounding to three decimal places, the B.T./N.B.T. (Invert Level at the end of the trench) is 11.970 m. That's 2 down. 3 left today — send the next one.
