In 2011, the City of Arlington, TX, needed a solution to correct a lack of sufficient water pressure in their 2,000,000-gallon sphere. The City turned to Phoenix to help solve their problem. Not only did the City have a pressure problem, but available space around the site was non-existent to deploy large hydraulic cranes to hoist the tank and place additional steel into place to make the structure taller.

After multiple site visits to complete an engineering analysis of the existing structure and foundation, Phoenix turned to its proprietary, hydraulic tank-jacking system with a plan to safely raise the 2,000,000-gallon tank 11 ft. The system operated internally from a structural girder designed and installed by Phoenix.

After multiple rounds of engineering verification and safety checking, and with hydraulics and surrounding hoists in place for load stabilization, Phoenix cut the tank loose in the stem section at 7 AM. The new stem sections were then put into place, and the tank was deemed secure by 11 PM that same evening.

In approximately 16 hours, Phoenix solved the pressure problem in a safe and efficient manner.

As a continually growing college campus, Penn State University needed to improve its water supply system. As part of this upgrade, Phoenix was contracted to raise each of the two large tanks an additional 16 ft. to accommodate greater head pressures.

Due to restrictive site conditions and adjacent structures, there was insufficient space to raise Tank 3, a 1,000,000-gallon sphere, using conventional hydraulic cranes. So Phoenix engineers developed a plan and tailored equipment to raise the tank with hydraulic cylinders. Once the tank was lifted, Phoenix crews worked to add the new stem sections and properly secure it before relieving the hydraulics.

The site was large enough to raise Tank 4, a 1,500,000-gallon, multi-column tank, using conventional hydraulic cranes. Phoenix engineered a plan that utilized six cranes to accommodate the 800,000-pound lift. The plan covered not only the engineering function of the lift but also the constant close communication among the operators, enabling them to work safely in unison. Once the tank was lifted, Phoenix crews added new leg and riser sections to it before relieving the cranes.
