Project Context & Strategic Objectives<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

For The Gambia, rural roads (feeder roads) are the arteries of the agricultural economy. Prior to this program, many rural communities faced “seasonal isolation” during the rainy season. This $20 million program was launched to achieve several critical national goals:<\/p>

  • Market Integration:<\/b> Connecting production zones in the interior directly to regional markets and the Trans-Gambia Highway.<\/li>
  • All-Season Mobility:<\/b> Ensuring that healthcare, education, and emergency services are accessible year-round, regardless of weather conditions.<\/li>
  • Logistics Efficiency:<\/b> Reducing the “wear and tear” on vehicles and lowering the cost of transporting agricultural produce to urban centers.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    The program involved a complex coordination of multiple sites, requiring Cornerstone to manage logistics across dispersed rural zones:<\/p>

    Feeder Road Rehabilitation & Construction:<\/b><\/p>

    • Sub-grade & Base Preparation:<\/b> Extensive earthworks involving grading and compaction to create a stable foundation capable of supporting heavy transport vehicles.<\/li>
    • Surface Treatment:<\/b> Application of durable surfacing designed to withstand the high-impact rain cycles of West Africa.<\/li><\/ul>

      Drainage and Erosion Engineering:<\/b><\/p>

      • Culvert Installation:<\/b> Strategic placement of reinforced concrete culverts to manage water runoff and prevent road washouts.<\/li>
      • Side Drains:<\/b> Construction of lined and unlined drainage channels to direct water away from the road structure, preserving the integrity of the pavement.<\/li><\/ul>

        Ancillary Civil Works:<\/b><\/p>

        • Road Safety Features:<\/b> Installation of essential signage and basic markings to improve visibility and safety for rural commuters.<\/li>
        • Access Management:<\/b> Ensuring safe interfaces between the new feeder roads and existing community footpaths and dwellings.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

          Cornerstone applied its Turnkey (Design-Build)<\/b> and Gestion de chantier<\/b> expertise to ensure consistency across all sites:<\/p>

          • Standardized Quality Control:<\/b> Implementing uniform material testing and construction methodologies to ensure that a road in the Upper River Region met the same high standards as one in the West Coast Region.<\/li>
          • Weather-Adaptive Scheduling:<\/b> Sequencing the heavy earthworks during the dry season to avoid the structural risks associated with building on saturated soils.<\/li>
          • Logistics Optimization:<\/b> Managing a complex supply chain for materials (laterite, gravel, cement) in remote areas where local availability can be a constraint.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
