• Stormwater Control Systems
• Fire Supression Systems
• Concrete Containment Systems

Foundation Design for the following equipment:

• (2) 108-ft tall process towers
• (2) 60-ft tall vertical heaters
• Several pump and exchanger units
• Structural steel pipe rack and equipment platforms
• Elevated vertical pressure vessels

Structural Steel Design for the following:

• 250 lineal feet of multi-level pipe rack design, which included a 44-ft pipe bridge to span over existing equipment.
• A multi-level equipment platform with a fin-fan unit supported approx. 22-ft above grade.
• The expansion of an elevated fin-fan platform to support an additional fin-fan and an exchanger unit.
