Question

Arrange the following stages of engineering surveys to be done for a new highway alignment project in the correct sequence:
A. Reconnaissance
B. Map study
C. Preliminary survey
D. Final location
E. Detailed survey
Choose the correct answer from the options given below :

• A. A, B, C, D, E
• B. C, B, A, D, E
• C. B, A, C, D, E
• D. B, C, A, D, E

Hint:

Mnemonic: "M-R-P-F-D". Map study is always first, and Detailed survey is always last. Reconnaissance is the first "field" activity.

Answer 1

The Correct Option is C

Concept: The planning of a new highway involves a series of survey stages that progress from general office studies to highly detailed field measurements.

Step 1: Office and site visits.
The process begins with a Map study (B) in the office to identify potential routes. This is followed by Reconnaissance (A), which involves a physical visit to the site to confirm map data and identify obvious obstacles.

Step 2: Comparison and selection.
A Preliminary survey (C) is then conducted on the shortlisted routes to collect detailed topographic and soil data, allowing for an accurate comparison.

Step 3: Finalizing the route.
Based on the preliminary data, the best route is chosen and established in the field during the Final location (D) stage. Finally, the Detailed survey (E) provides all the data needed for construction plans and cost estimation.
