JV & Design Coordination

Independent structural review, finite element analysis, and design optimization for one of Africa's largest concrete gravity dam and hydropower developments, ensuring structural integrity, seismic resilience, and long-term operational performance.

Advanced numerical modeling and finite element analysis were conducted using a comprehensive suite of industry-leading software including ANSYS, SAP2000, Strand7, Diana, and GeoSlope, enabling detailed assessment of stress distribution, deformation patterns, and stability margins under static, dynamic, and seismic loading conditions. The analysis encompassed the full spectrum of structural verification — from ultimate strength and serviceability checks under operational and extreme flood conditions to rigorous seismic performance evaluation for PGA 0.25g, ensuring compliance with ICOLD, ACI, Eurocode, and EMUS standards.

Detailed stability analysis of the main RCC gravity dam was performed, including foundation interaction modeling, thermal stress evaluation during construction and operation, and seepage and uplift pressure analysis to verify long-term durability. For the extensive network of saddle dams — totalling 15.2km in length, including an 8km concrete face rockfill dam  slope stability assessments, seepage analysis, and deformation modeling were conducted using GeoSlope and advanced geotechnical software. Soil-structure interaction was rigorously evaluated to ensure foundation integrity and performance under variable subsurface conditions.

Structural verification extended to the power tunnel systems, surge shafts, and powerhouse, evaluating the 12m × 17m diversion tunnel and power water tunnel configurations with penstocks and manifold systems. Fatigue analysis, dynamic response checks, and construction stage assessments were performed to ensure the structural reliability of all hydraulic components. An optimization study on grouting methods was conducted based on Grouting Intensity Number, analyzing geotechnical data to improve foundation treatment and structural performance. This independent review provided the project owner, lenders, and design teams with comprehensive, evidence-based assurance of structural safety, regulatory compliance, and capital protection for this critical national infrastructure, valued at $4 billion USD.

RCC Dam Analysis

Structural Stability & FEA Verification

Comprehensive 3D finite element modeling was executed using a suite of advanced analytical tools including SAP2000, ANSYS, and Strand7 for the main RCC gravity dam and powerhouse structures, capturing full structural response under static, thermal, and dynamic loading conditions. Detailed seismic performance evaluation was conducted for PGA 0.25g, assessing stress distribution, deformation patterns, and stability margins under extreme earthquake scenarios. Concurrently, GeoSlope stability analysis was performed for the extensive network of rockfill saddle dams, totaling 15.2km in length, evaluating slope stability, seepage regimes, and deformation behavior under seismic loading. Soil-structure interaction, foundation settlement, and liquefaction potential were rigorously assessed to ensure long-term stability and operational safety. All numerical analyses were validated against international standards including ICOLD, Eurocode, and ACI, providing independent assurance of structural integrity, regulatory compliance, and capital protection for this critical national infrastructure.

Tunnels & Grouting

Surge Shaft & Grouting Optimization

Independent structural review and verification of lining designs for the power tunnel and surge shaft were conducted, ensuring structural integrity, hydraulic performance, and long-term durability under high-pressure operating conditions reaching up to 210m water column. Comprehensive finite element analysis was performed to evaluate lining stability, stress distribution, and deformation behavior under internal water pressure, external earth and water loads, and seismic loading conditions. Reinforcement detailing and crack control measures were reviewed to ensure compliance with serviceability and durability requirements for a 50-year design life. Foundation grouting parameters were systematically optimized using Grouting Intensity Number (GIN) methodology, analyzing geotechnical data to calibrate grouting pressures, volumes, and mix designs for maximum foundation improvement and seepage control. All analyses and design verifications were carried out in strict compliance with international standards including ICOLD guidelines for dam and tunnel design, Eurocode for structural design, and ACI codes for concrete materials and construction.
