Concept explainers

Control Survey and Geodetic reductions

Control surveys or survey controls are used to establish reference points as a basis for various construction activities. Vertical and horizontal control points are to be established in a control survey to increase accuracy. After establishing the control points, all other types of surveys such as topographic, right-of-way, aerial mapping, construction layout, boundary surveys, and utility mapping can be worked upon so that control networks can be formed. The place from which the observations are made is called a survey station.

1. A tachometric surveying was conducted to obtain some readings for inaccessible points, where it was found that the multiplying and additive constants are 98 and 0.1, respectively. The instrument was setup at point C and the readings listed in the table were taken while the staff was held vertically. Calculate the horizontal distance between BM and station D. Also, calculate the reduced level of station D. Figure 1 shows a schematic view of the site. 2. Describe a practical procedure to measure the height of your house using tachometric surveying, list the procedure in bullet points.
The following consecutive readings were taken with a level and a 4m leveling staff on a continuously sloping ground at a common interval of 30 m on line AB. Chainage 0 Level Station 30 0.585 0.930 A 60 1.95 90 2.845 120 3.645 150 3.93 B The reduced level (RL) of station A is 50.00. Calculate the reduced levels at all the points where the leveling staff is placed. Tabulate the results and apply usual checks. Also determine the gradient of line AB.
When performing a leveling process for the longitudinal section of a road, the following readings were recorded: The first reading was taken on the leveling number (B.M1), whose Tevel is (60 meters), while the rest of the points were taken on the section points (00+0. 0+50 + 00+ 1... . (While working, lift the device after the fourth, seventh, and tenth reading. Arrange the readings in a table, then complete the table and verify the correctness of the calculations.
