Reconnaissance survey means
A. Conducting the survey to get the plan of the site.
B. Conducting the survey to get contours of the site.
C. Visual inspection of the site and study of the topographical features
D. None of the above
Correct Answer: C. Visual inspection of the site and study of the topographical features
A. Conducting the survey to get the plan of the site:
This option implies that a reconnaissance survey is done solely to obtain a detailed plan of the site. However, this is not the primary purpose of the reconnaissance survey. A reconnaissance survey is conducted in the preliminary stages of a project to gather general information about the site and its surroundings. It involves a broader assessment of the area’s suitability for a particular project rather than obtaining a detailed plan.
B. Conducting the survey to get contours of the site:
While obtaining contours might be part of a detailed survey, it is not the main focus of a reconnaissance survey. Contours refer to the lines on a map that connect points of equal elevation. A reconnaissance survey is more about gaining a basic understanding of the site’s features, including its topography, vegetation, accessibility, and potential challenges.
C. Visual inspection of the site and study of the topographical features:
This is the correct option. A reconnaissance survey involves visiting the site and visually inspecting it to understand its topographical features, soil conditions, vegetation, drainage patterns, accessibility, neighboring structures, and other relevant factors. The goal is to gather preliminary information that helps in decision-making for further stages of planning and design.
D. None of the above:
This option is not accurate because option (C) is indeed the correct description of a reconnaissance survey. It involves visual inspection and studying topographical features for a preliminary assessment of the site’s suitability for a project.
