Lean, Innovative, and Unique Project Solutions

The Cianbro team solved several heavy rigging challenges. Cianbro lifted and placed 185-ton gas turbines with a special gantry crane, rolled a 475,000-pound condenser into place after assembly, and made several crane picks to upright and set the 375,000-pound HRSG tube modules.
