Description
This project consisted of comprehensive technical and environmental supervision for the construction and paving of 30 km of the La Central-Isiri road section, part of the Fundamental Road Network. The supervision ensured the execution of the work in accordance with engineering, safety, quality, and environmental standards. Technical Scope of Supervision The supervision included a rigorous control of: Review and Validation of the Final Design Study (EDF): Documentary Analysis: Verification of topographic studies (surveys, profiles), geotechnical (subgrade, sub-base, base; SPT, CBR, Modified Proctor), pavement design (structure, thicknesses, material properties - Marshall for asphalt, compressive strength for concrete), and hydraulic/drainage design (ditches, culverts, sub-drains). Identification of Non-Conformities: Detection of inconsistencies or deviations. Construction Execution Supervision: Earthworks: Control of cuts, fills, and subgrade formation, including verification of compaction degrees (nuclear densimeters). Pavement Structure: Granular Sub-base and Base: Inspection of aggregate quality, granulometry, optimal moisture, and compaction. Asphalt Layers: Supervision of manufacturing at the plant (temperatures, binder dosage), laying, and compaction in the field (final densities). Quality control of asphalt (penetration, softening point). Drainage Works: Inspection of ditches, culverts, and sub-drains. Signaling and Road Safety: Verification of horizontal/vertical signage and safety barriers in accordance with Bolivian regulations. Environmental Supervision: Monitoring of the Environmental Management Plan (EMP): Verification of compliance with mitigation and compensation measures of the Environmental License. Impact Control: Supervision of waste management, erosion/sedimentation, air quality, and management of borrowing/pit sites. This supervision was crucial to achieving a high-quality, safe, durable, and environmentally sustainable paved road infrastructure, improving connectivity and regional development.
