Consultancy Services for Detailed Engineering Design of Various Low Volume Roads Using Appropriate Low-Cost Sealing Technology, Lot 10: Arua-Giligili-Ovision Road.

The Uganda National Road Authority (UNRA) is planning to upgrade the Arua-Giligili Ovision Road using low-cost sealing technology. To support this initiative, M/S KKAAT Consult Ltd was contracted to provide detailed engineering design consultancy services, with SADRiNE Infrastructure Services (SID) Limited sub-contracted to conduct geotechnical, soils, and materials investigations. These investigations included alignment soil test pitting, dynamic cone penetration testing, and construction materials surveys to inform the pavement design process and ensure the suitability of materials used.
The comprehensive geotechnical investigations aimed to determine subgrade characteristics and identify appropriate construction materials. Activities included trial pitting, dynamic cone penetration tests, and sampling of soil, aggregates, and water for laboratory analysis. The findings, compiled in a factual report, provided essential data for the engineering design, ensuring the technical feasibility and sustainability of the proposed road upgrade, ultimately contributing to the project’s successful implementation.
