Narrative Description of Project:

The Government of Gilgit Baltistan (GoGB) envisioned improvement of major towns, based on the principles of modern urban and town planning. In the spirit of this vision, the GoGB planned to establish Gilgit and Skardu Development Authorities. The aim was:
  • To establish a comprehensive system of planning & development in order to improve the quality of life in the cities of Gilgit and Skardu
  • Establish an integrated development approach and a continuing process of planning and development
  • To ensure optimum utilization of resources
  • Economical and effective utilization of land and to evolve policies and programs relating to development of traffic, transportation, health, education, water supply, sewerage, drainage and other related public facilities and utilities
  • . The P&DD has undertaken an approach to map and examine the efficacy of the existing inventory related to urban planning in the proposed town areas of Gilgit and Skardu termed ‘Project Area’. Based on the outcome, appropriate master plans shall be prepared, in consultation with all stakeholders. The master plans, once approved and notified, shall serve as the basis of future urban development of the project area. Adequate organization shall be then put in place as development authorities to execute the approved master plans. The consultant carried out a detailed exercise comprising study, survey, digitizing and developing a ‘GIS based Digital Base Map for Gilgit and Skardu, which at a later stage would be utilized for master plan development of the said areas.

    Description of Actual Services Provided by Our Staff within the Assignment:

    ETS, a sister concern of Exponent Engineers was hired to perform the project, the project had following scope:
