Q1) A highway is to be constructed to pass through points A and E of the traverse. The proposed highway grade is + 2.3 percent rising from A to E ( elevation at A = 68.95 and at B = 73.62). The ground level elevation of the cut and fill at the midpoint of formation are 70.65 and 71.72 m respectively. Compute the volume of below cut and fill sections. Elevation of the bed is 67.45. Apply for two stations long.

Q2) A five -sided closed traverse has the following angles Q2) A five -sided closed traverse has the following angles. The lengths of the sided are as follows: AB= 50.276 m BC= 26.947 m CD= 37.090 m DE= 35.292 m EA= 20.845 m The bearing of EA is N20o 20/ 20//W, and AB oriented northeasterly

a) Compute the bearings c) Compute the latitudes and departures d) the linear error of closure and the accuracy ratio. e) Compute the coordinates of the other stations if the coordinates of station A are 1000.000 N ,1000.000 E.
