Reconnaissance Survey in Civil Engineering

Reconnaissance survey is the first and preliminary survey conducted to gather information about the area in which the project is proposed. It is a survey in which details are covered roughly but not accurately. The purpose of this survey is to obtain an idea of the general characteristics of the terrain and its suitability for the proposed project.

Importance of Reconnaissance Survey

The reconnaissance survey is essential to form a general idea of the area and provides the necessary information required for the preparation of the project. It helps in the following ways:

1. Preliminary Information

Reconnaissance survey provides preliminary information about the site, including the topography, geology, climate, and vegetation of the area.

2. Site Selection

It helps in selecting the most suitable site for the project by studying the existing conditions of the area.

3. Cost Estimation

It helps in estimating the cost of the project by providing data on the general characteristics of the site.

4. Planning

It provides information for planning the detailed survey and designing the project.

Methods of Reconnaissance Survey

The following methods are used in the reconnaissance survey:

1. Map Study

A map study is conducted to get an idea of the area's topography, location, and accessibility. It helps in locating the important features of the area, such as rivers, hills, and roads.

2. Aerial Photography

Aerial photography is used to obtain an aerial view of the area, which helps in identifying the features of the terrain.

3. Field Observation

Field observations are conducted to study the soil, vegetation, and climate of the area.

Conclusion

Reconnaissance survey is the first and preliminary survey conducted to gather information about the area in which the project is proposed. It is a survey in which details are covered roughly but not accurately. The purpose of this survey is to obtain an idea of the general characteristics of the terrain and its suitability for the proposed project.
