A pre-engineering baseline was run down a very steep hill (see Rather than measure horizontally downhill with the steel tape, the surveyor measures the vertical angle with a theodolite and the slope distance with steel tape. The vertical angle is -21° 26’ turned to a point on a plumbed range pole that is 4.88 ft above the ground. The slope distance from the theodolite to the point on the range pole is 148.61 ft. The theodolite’s optical center is 4.66 ft above the upper baseline station at 110 + 71.25. If the elevation of the upper station is 318.71. what is the elevation of the lower station? What is the horizontal distance between the two stations?

The results of a CPT test performed for a commercial site are presented in the image (You already classified the soil layer in homework #2). The layer soil type is shown by the legend and corresponding numbers in the figure. A strip footing with a size of 3x30 is built on the surface of the mentioned strata. A 300 kN/m load is acting on the footing. Use Schmertmann's method to compute the settlement of this footing 1 year after construction and 30 years after construction. Please show your calculation for at least one layer if you want use excel software for this problem. For easier calculation use E₂ = 39c- • • Neglect the foundation weight. • Assume the layers are in dry condition. Use unit weight as table below. Layer No. 1 2 3 4 5 6 7 Unit weght kN/m3 17 17 19 18 18.5 18 18
