In the planning of metro project, what are the chronology of activities before the construction?

The chronology of activities before the construction of a metro project typically includes the following steps:

1. Project Conception: This is the initial stage where the need for a new metro line is identified. This could be due to increasing population, traffic congestion, or a need to improve connectivity in a certain area.

2. Feasibility Study: A feasibility study is conducted to assess the viability of the project. This includes studying the proposed route, estimating the cost, and assessing the potential impact on the environment and local communities.

3. Detailed Project Report (DPR): Based on the feasibility study, a detailed project report is prepared. This includes detailed designs, cost estimates, and a project implementation schedule.

4. Approval and Funding: The DPR is then submitted to the relevant authorities for approval. Once approved, the funding for the project is secured either through government funding, loans, or public-private partnerships.

5. Land Acquisition: The necessary land for the construction of the metro line and stations is acquired. This may involve negotiations with landowners and possibly resettlement of people.

6. Tendering: The construction work is usually divided into several packages, and tenders are invited for each package. The contractors are selected through a competitive bidding process.

7. Design Finalization: The final design of the metro line and stations is completed. This includes the architectural design of the stations, the track layout, and the design of the electrical and mechanical systems.

8. Statutory Clearances: All necessary statutory clearances are obtained. This includes environmental clearances, safety clearances, and any other permissions required by law.

9. Pre-construction Activities: These include setting up the construction site, mobilizing resources, and making necessary arrangements for construction.

Once all these steps are completed, the actual construction of the metro project can begin.
