• <strong>Projects Description:</strong>
• Transgabonaise Road (KP 24 to KP 105), Gabon-EPC Contract between SAG and Afcons · Multi-billion XAF international infrastructure arbitration.
• <strong>Key responsibilities & deliverables:</strong>
• Helped prepare and quantify nine claim categories totalling several billion XAF, including variation orders, prolongation costs, head office overheads, loss of profit, disruption/productivity loss, and arbitration costs.
• Built and validated Excel models for delayed profit financing charges, calculating monthly shortfalls between milestone contract values and actual IPCs, using the BEAC marginal lending rate plus a 5% spread over more than 36 periods (XAF ~342 Mn).
• Developed demobilization cost schedules (Feb-26,Mar-26), classifying 13 cost categories (such as indirect labour, P&M hire, security, food, land rental) and distributing costs daily during the post-termination period.
• Supported analysis of 13 variation order claims (VO-01 to VO-15, XAF ~14.2 Bn), verifying onsite overheads, head office overheads, and profit components included in each claim's assessed value.
• Helped with interest calculations on the SAG counterclaim (Appendix K), modelling liquidated damages and advance payment recovery interest using the BEAC TIAO rate (5% to 4.5%), with payment-event-based drawdowns, totalling approximately EUR 3.1 Mn.
• Gained understanding of international arbitration principles, including FIDIC-based EPC contract mechanisms, pendente lit interest, liquidity damages, mobilisation advance recovery, disruption claims methodology, and quantum expert report preparation.
