Designing for delivery: tower spotting strategies to accelerate transmission line design and construction under South Africa’s TDP2024

South Africa’s Transmission Development Plan 2024 (TDP2024) requires the accelerated delivery of overhead transmission lines. This ambitious rollout must be achieved under constrained budgets, compressed schedules, and a diminishing pool of experienced transmission line design and construction resources. These pressures necessitate consideration for a shift from purely least-mass design philosophies toward design-for-delivery approaches that optimise performance across the full project value chain.
