Overview

Identifies critical factors causing site clearance delays in ODA-funded projects, suggesting strategies for improvement.

Key Points

  • The research aims to identify and categorize factors leading to site clearance bottlenecks in ODA-funded infrastructure projects in Vietnam.
  • Identified 22 potential SCB factors via literature review and expert consultations.
  • Surveyed 140 stakeholders using a structured questionnaire.
  • Analyzed data with Cronbach's alpha, Kruskal-Wallis test, and hierarchical clustering.
  • Financial issues and unstable market conditions emerged as the top factors affecting site clearance.
  • The study found strong consensus among stakeholders on key SCB factors.
  • Four major groups of SCB factors were classified: financial pressures, compensation issues, administrative constraints, and procedural challenges.
