T he project included design, procurement, and construction for soil improvements and ringwall foundations for 10 above-ground cone roof storage tanks. Work included in this project is a complete foundation system.

Each 120-ft x 60-ft tank had a minimum shell capacity of 120,000 bbl and weighed 900,000 lbm (tank steel plus internal floating roof). The design contemplated a product specific gravity of 0.84 for products such as gasoline, diesel, blendstocks, and ethanol. The design included cathodic protection.

The work included the following:

• Complete foundation design for each tank, certified by a Texas professional engineer
• All equipment, materials, supervision, and labor to construct and test the tank soil improvements and foundation system
• Design criteria for ramps and roads to accommodate installation equipment, design for load transfer platform, and design for the concrete ringwall foundation
• Complete site work including containment dikes and roads
• Assisting with hydrotesting
