In the second phase, which started in July, Keller is installing 140 large-diameter rotary bored piles, reaching depths of up to 36.5 metres.
The CFA piling works will form a significant part of the scheme, with more than 330 piles installed across multiple diameters, some reaching depths of more than 31 metres.
Keller will also be installing more than 200 restricted access piles in areas with limited working space.
Richard Smith, Keller's Preconstruction Manager - Foundations, said: "We are proud to play a significant role in preparing the site for the construction of the new electric arc furnace, which will help secure the long-term future of steel manufacturing at Port Talbot.
"By offering multiple foundation and ground improvement techniques, Keller is not constrained to a single approach and can instead select or combine methods that best meet project-specific constraints.
"This flexibility allows us to optimise designs, reduce material usage, and improve efficiency while maintaining performance requirements."
