Background
A government entity was undertaking a massive irrigation project covering more than 4,500 square kilometers. The full scope of work included survey, design, procurement, construction, and installation of pumping systems. To start the project, a massive land survey of the entire project area was required to account for terrain features that could impede construction progress. The project also necessitated a bathymetric survey to understand the bodies of water.
Challenges
Traditional means of land surveying would have been problematic due to the size of the land area and challenging geography – with elevation variations of up to 300 meters. Dense forest areas also posed challenges, with wildlife and thick vegetation making it unsafe for manual survey. Also, because of the variety of the landscape, the team was running into challenges related to gaining permits and permissions for access in some areas.
- The project required detailed surveying prior to construction
- Dense forestry complicated traditional survey efforts
- Both geographic and bathymetric surveys were needed
