What is the primary purpose of a reconnaissance survey in engineering surveying?
A) To establish control points for the survey.
B) To collect detailed measurements and data.
C) To identify suitable project locations.
D) To perform boundary demarcation.
View Answer
Correct Answer: C) To identify suitable project locations.
Explanation: A reconnaissance survey is conducted to identify potential project locations by gathering preliminary information about the terrain, accessibility, environmental factors, and other relevant aspects. This helps in making informed decisions about project feasibility.
Which type of survey involves the determination of the relative positions of points on the Earth’s surface using angular and linear measurements?
A) Topographic survey.
B) Geodetic survey.
C) Hydrographic survey.
D) Route survey.
View Answer
Correct Answer: B) Geodetic survey.
Explanation: Geodetic surveys focus on accurate measurements of the Earth’s shape and the establishment of precise reference points. This involves using angular and linear measurements to determine the positions of points on a global scale.
What is the purpose of a control survey in engineering surveying?
A) To measure distances and angles for detailed mapping.
B) To establish reference points for other surveys.
C) To determine elevations and contours of the terrain.
D) To create detailed profiles of existing structures.
View Answer
Correct Answer: B) To establish reference points for other surveys.
Explanation: A control survey involves establishing accurate and reliable reference points or control points that are used as a basis for conducting subsequent surveys with high precision.
Which type of survey is used to determine the precise location of boundaries between properties?
A) Topographic survey.
B) Cadastral survey.
C) Route survey.
D) Construction survey.
View Answer
Correct Answer: B) Cadastral survey.
Explanation: Cadastral surveys are concerned with defining property boundaries and land ownership. They play a crucial role in legal and administrative matters related to land.
In a construction survey, what is the purpose of a stakeout survey?
A) To determine the topography of the construction site.
B) To establish reference points for control surveys.
C) To mark the precise locations where structures should be built.
D) To create detailed elevation profiles of the terrain.
View Answer
Correct Answer: C) To mark the precise locations where structures should be built.
Explanation: A stakeout survey involves marking the exact positions and dimensions of proposed structures on the ground, based on construction plans. This ensures accurate placement during the building process.
Which type of survey is used to collect data about the depth and features of bodies of water?
A) Topographic survey.
B) Cadastral survey.
C) Hydrographic survey.
D) Geodetic survey.
View Answer
Correct Answer: C) Hydrographic survey.
Explanation: Hydrographic surveys focus on collecting data related to bodies of water, including their depths, features, and underwater terrain. This information is important for navigation, engineering projects, and environmental assessments.
What is the primary purpose of a route survey in engineering?
A) To determine the ownership of properties along a route.
B) To establish reference points for control surveys.
C) To plan and design transportation corridors.
D) To measure the volume of earthwork required for construction.
View Answer
Correct Answer: C) To plan and design transportation corridors.
Explanation: A route survey involves identifying and designing transportation routes, such as roads, highways, railways, and pipelines. It helps in determining the optimal path, alignment, and design of these corridors.
Which type of survey focuses on capturing the physical features and elevations of a land area?
A) Hydrographic survey.
B) Geodetic survey.
C) Topographic survey.
D) Construction survey.
View Answer
Correct Answer: C) Topographic survey.
Explanation: Topographic surveys involve mapping the natural and man-made features of a land area, including its contours, elevations, vegetation, water bodies, and structures.
What is the purpose of a monitoring survey in engineering?
A) To establish reference points for control surveys.
B) To measure changes in the position or condition of structures over time.
C) To determine the depth and features of bodies of water.
D) To create elevation profiles of a terrain.
View Answer
Correct Answer: B) To measure changes in the position or condition of structures over time.
Explanation: Monitoring surveys are conducted to track and analyze changes in the position, condition, or behavior of structures, such as buildings, bridges, and dams, over a certain period of time.
Which type of survey is primarily concerned with capturing information about the physical features and characteristics of the Earth’s surface?
A) Cadastral survey.
B) Geodetic survey.
C) Topographic survey.
D) Hydrographic survey.
View Answer
Correct Answer: C) Topographic survey.
Explanation: Topographic surveys are conducted to gather detailed information about the natural and man-made features of the Earth’s surface, including its elevations, contours, and physical attributes.
