Prysmian Du Quoin Plant: one plant, four clients

Cable reels staged outside the Prysmian plant in Du Quoin, Illinois, with storage silos and process structures behind.

G&W started at Prysmian’s Du Quoin plant in 2023 with a cooling tower selection and an electrical service study for a general contractor. That led to engineer of record work on a 119,300 SF expansion, then MEPFP for four more building additions and civil design for a new truck route. The teams changed along the way. We’re still here, now working directly for the owner too.
