Overview
The challenge. A new 14 kilometre, 63kV transmission line between Gakpe and Ouidah in Benin needed complete line and tower design — not an adaptation of an existing family of structures, but lattice steel towers designed from geometry up, to CEB technical standards, ready for local fabrication and erection.
Our approach. Our team is responsible for the complete design: the lattice steel towers and all associated structural analysis, delivered using TOWER and PLS-CADD. The design package spans tower geometry, load case analysis and foundation design, with the line design and tower design carried by the same team so that span lengths, tower positions and structure capacities are optimised together rather than sequentially.
The outcome. Towers designed by TAWARA Group are now erected along the Gakpe to Ouidah corridor — including completed 63kV double-circuit lattice suspension towers — with our engineers conducting construction supervision visits along the 14 kilometre alignment as the line advances toward energisation.
