What is the reconnaissance survey?
The reconnaissance survey is an extensive study of an entire area that might be used for a road or airfield. Its purpose is to eliminate those routes or sites which are impractical or unfeasible and to identify the more promising routes or sites. The reconnaissance survey must include all possible routes and sites.
Accordingly, what is the next stage of reconnaissance survey?
It has four phase study processes as follows, 1) Research, 2) Draft report outline, 3) Draft sensitivity map and 4) Final report. Purpose of reconnaissance survey is discussed below.
Similarly, what is known as site reconnaissance? Site reconnaissance (a walkover survey): Identifying actual and potential hazards and the design of the main investigation. Main investigation and reporting: Including intrusive and non-intrusive sampling and testing to provide soil parameters for design and construction.
Beside above, what is reconnaissance or preliminary survey?
1) Reconnaissance survey : To explore site conditions and availability of infrastructures. 2) Preliminary survey : To collect adequate data to prepare plan / map of area to be used for planning and design. 3) Location survey : To set out work on the ground for actual construction / execution of the project.
What is reconnaissance survey in Archaeology?
