The Statue of Liberty Rehabilitation

This World Heritage Site project is focused on repairing the prominent masonry stone walls and terreplein deck of Fort Wood, the 11-pointed star-shaped granite fort built between 1808 and 1811 that houses the Pedestal on which the Statue of Liberty stands.  

The rehabilitation of the stone walls covered approximately 35,000 vertical square feet of historic granite masonry, involving meticulous repair and repointing of deteriorated joints, thorough cleaning and replacement of coping stones, and precision masonry work on delicate Schist Stone elements.

The rehabilitation of the terreplein covered approximately 50,000 horizontal square feet of hardscape surfaces, including 2 masonry stairwells leading to the base of the monument.

For the People

Precision and care are the major players in this game when repairing a landmark representing freedom and possibility for so many. Every step matters, from loading, unloading, and material selection to the actual placement and masonry restoration, as the outcome must be perfect. To that point, custom-designed scaffolding and ramp systems had to be designed and erected to accomplish goals like providing better access for transporting said materials up and down from the Terreplein Level without compromising the historic walls.
