QUESTION ONE a) Suppose Mulungushi University has engaged you to conduct chain survey to measure a parcel of land at main campus. Explain how you would conduct this task. b) With the aid of diagrams, explain the cardinal principles of surveying. c) The level book entries shown below were made in rainy weather. 0.855 (on A), 1.545, 2.335, 3.115, 3.825, 0.455, 1.380, 2.055, 2855, 3.455, 0.585, 1.015, 1.850, 2.755, 3.845 (on B); The reduced level of A was 380.500. i. Draw up a level table in your answer book and reduce levels by rise and fall method on a continuous sloping ground with four-meter leveling staff at common intervals of 30m. Complete appropriate checks and determine the misclosure ii. If the survey had been booked using the collimation method, what would be the height of the planes of collimation at the tbm and change points? iii. Determine the gradient of AB. [8+4+7+4+2) QUESTION TWO a. Distances are very important in Surveying as they determine the scale of a network. Several methods are used for distance determination. The method of choice for distance determination depends on a number of factors. Provide an outline of these factors. b. A survey line was measured with a tape, believed to be 20m long, and a length of 284.623m resulted. On checking, the tape was found to measure 19.951m long, i. What is the correct length of the line? ii. If the line lay on a slope of 1 in 20, what would be the reduced length used in the plotting of the survey? iii. What reading is required to produce a horizontal distance of 15.085m between two site pegs, one being 0.662m above the other? c. What corrections can be applied to a measured line to bring it to a corrected horizontal distance? [5+5+5+5+5) QUESTION THREE a) Suppose an organization intends to give you a short-term contract to carry out linear measurements for a project they are undertaking. Provide a clear step by step account on how you would implement this project. Your solution should also indicate the minimum man power and equipment required to execute the project. b) A railway embarkment of formation width of 10m and side slope 3:1 is required to be made on a ground which is level in a direction traverse to the centre line. The central heights at 20m intervals are as follows: 0.5, 2.5, 3.00, 5.0, 4.0, 3,20 and 0.4. Compute volume of earth works. c) The coordinates (Easting, E and Northing, N) of station Pin a traverse survey are given as 1000ME and 1000MN. The bearings and distances of some of the traverse lines are given below: Line Bearing Distance PO 130 156M a QUESTION ONE a) Suppose Mulungushi University has engaged you to conduct chain survey to measure a parcel of land at main campus.
