IDENTIFICATION (EI) AND TECHNICAL, ECONOMIC, SOCIAL AND ENVIRONMENTAL STUDY (TESA) FOR THE CONSTRUCTION OF THE CHULUMANI - IRUPANA - SACAMBAYA ROAD SECTION CAJUATA - RIO SACAMBAYA

General Description

The project consisted of the execution of the Identification Studies (EI) and Technical, Economic, Social and Environmental (TESA) necessary for the construction of 76 kilometers of the Chulumani - Irupana - Sacambaya road, Cajuata - Río Sacambaya section. The key technical deliverables of this study included: Road Engineering: Topographic Studies: Surveys with total station and/or GNSS for generating topographic plans to scale, longitudinal and transverse profiles, and work volumes. Geometric Road Design: Development of layout alternatives, optimization of horizontal and vertical curves, definition of typical cross-sections and intersection details, under Bolivian ABC regulations. Design of Art Works: Calculation and sizing of drainage structures (culverts, bridges, vaults), retaining walls and complementary works. Geotechnics and Hydrology: Soil and Geology Investigation: Execution of exploratory drilling, test pits, and laboratory tests (Atterberg limits, granulometry, CBR, direct shear, unconfined compression) for the classification and characterization of subgrade and embankment materials. Slope Stability Analysis: Geotechnical modeling to determine safety factors of slopes and design of stabilization solutions (reinforced embankments, berms, anchors). Hydrological Studies: Determination of hydrological design parameters (maximum precipitation, concentration time, design flows) for the sizing of the drainage system. Hydraulic Design: Hydraulic modeling of crossing structures and longitudinal works to ensure efficient water flow and erosion protection. Complementary Studies: Traffic Engineering: Future traffic projections (IMDA) and level of service analysis. Environmental Assessment: Identification of significant impacts and proposal of an Environmental Management Plan (EMP) including mitigation and monitoring measures. Socioeconomics and PRP: Determination of the socioeconomic baseline and development of the Loss Replacement Program, with compensation and rehabilitation plans.
