Broad Scope of Work 

The Final Location Survey involves various technical tasks such as:

  • Fixing the alignment for the project.
  • Pegging out the centerline accurately.
  • Taking levels to determine elevation and terrain.
  • Finalizing land requirements, surveying by specific survey numbers.
  • Conducting soil investigations.
  • Performing geological investigations for bridges, which may include drilling boreholes and collecting samples.
  • Calculating waterway requirements for all proposed bridges.
  • Preparing General Arrangement Drawings (GADs) for bridges, station yards, and project sheets.
  • Utilizing stereo satellite imagery data from NRSC (National Remote Sensing Centre) and BISAG-N.
  • Processing this data using suitable GIS software to generate Digital Elevation Models (DEMs), orthophotos, topo-maps, etc.
  • Submitting a detailed estimate for the project, including a traffic survey report and Right of Way (ROR) calculations.
  • Completing various survey works with the assistance of LiDAR (Light Detection and Ranging) technology.

What is Final Location Survey (FLS)?

A final location survey is the first important step that is carried out during detailing of any railway project. It is in this survey where multidisciplinary investigations like topographical, geotechnical, hydrological etc. are taken up and the consolidated data is used to finalise route alignment and identify land usages.

Conducting a Final Location Survey for the construction of railway infrastructure projects is a comprehensive task. This involves multiple steps, which can be summarized as follows:

  • Survey and Estimation: This includes the preparation of detailed estimates for various components, including Civil (C), Signal & Telecommunication (S&T), Electrical (G) & OHE (Overhead Equipment) works.
  • Traffic Report: Conducting traffic surveys and preparing a comprehensive traffic report to understand the expected volume of railway traffic in the proposed project area.
  • Economic Analysis: Calculating Economic Internal Rate of Return (EIRR) and Financial Internal Rate of Return (FIRR) to assess the project’s economic viability.
  • Detailed Project Report (DPR): Preparing a Detailed Project Report that outlines the project’s specifics, including technical details, cost estimates, financial analysis, and environmental impact assessments.
  • Geotechnical Investigation: Conducting geotechnical investigations to understand the soil and geological conditions at the project site. This is critical for the design and construction of foundations, bridges, and other structures.
  • EPC Document Preparation: Preparing the Engineering, Procurement, and Construction (EPC) document that outlines the scope of work, technical specifications, procurement processes, and construction requirements.
  • Packaging: Organizing and packaging all the project-related documents, including the DPR, estimates, survey data, geotechnical reports, and EPC documents, for further evaluation and implementation.
