Detailed Survey of Marshyangdi 132 kv Transmission Line Corridor Project

Funding Agency: GoN
Clients: NEA, Engineering Services, Project Development Department
Date:  Jan 2010 – Jun 2010

The objective of the study is to determine the suitable shortest route alignment and carry out detail route survey of Marshyangdi 132 kV transmission line corridor project.

The detail route alignment survey will study the topographical features of the transmission line alignment such as rivers crossings, road crossings, power line and other structures and their details. It will then fix the final route alignment of the 132 kV Transmission line determining the most appropriate shortest route possible.

The final output of the survey will be a guideline for the construction of the transmission line. The detailed survey will also be used in preparing the necessary documents for acquiring construction license, and in conducting ACRP, EIA/IEE and others.

Overall Services provided by firm:

TMS provided consulting services to carry out the preliminary study to identify potential small and medium-scale feasible hydropower sites in Gandaki and Karnali river basins and obtain a survey license from the DOED for further detail studies to develop the project commercially.

Scope of work of the project included:

  • Collection of documents, information, data maps, aerial photo etc from the relevant offices;
  • Desk study and identification of potential hydropower sites;
  • Confirmation of sites from the DOED whether license have been issued already or not;
  • Assessment of power potential and energy generation characteristics of the site;
  • Conducting field verification and confirming head and design discharge at the site;
  • Conducting geo – technical investigation of project sites;
  • Hydrological study of river to get hydrological parameters;

The basic approach to carry out the study of the transmission line will consist of the following activities conducted in the same order:

  1. Basic data collection
  2. Desk study
  3. Reconnaissance survey
  4. Detail Alignment survey
  • Documentation of benchmarks along the entire line corridor
  • Fixing of concrete pillar at every angle points
  • Strip mapping of final route alignment
  • Fixing of substation boundaries
  • Preparation of plan and profiles in appropriate scale
  • Preparation of survey report with al maps and drawing in latest CAD format.
