Diamond Green Diesel No. 2 Plant Expansion
Award of Merit
OWNER: Diamond Green Diesel LLC
LEAD DESIGN FIRM: Primoris Design and Construction
GENERAL CONTRACTOR: Primoris Energy Services; Primoris Industrial & Civil Design
The $39-million Diamond Green Diesel No. 2 Plant Expansion was designed to more than double the capacity of renewable diesel at DGD’s Norco, La., refinery.
Construction involved the logistical challenges of working in a live facility with a small footprint. Primoris Design and Construction worked with the owner to coordinate the movement of materials and work execution without interrupting existing plant operations.
Workers faced the safety challenge of installing structural steel above energized electrical cables in cable trays. To contain electrical sparks, workers placed fire-resistant plywood and fire blanketing around the existing tray and wrapped scaffolding for protection.
