Description

Designed by James Renwick Jr. in the Gothic Revival style and constructed between 1858 and 1878, St. Patrick’s Cathedral is an Individual New York City Landmark and a National Historic Landmark. Ongoing leakage into mechanical spaces under the plazas required repair, and Nicholson & Galloway was contracted to perform the following work:

• 6,730 cubic feet of soil excavation
• 4,500 square feet of existing plaza demolition
• 6,000 square feet of new concrete pitched fill
• 7,000 square feet of Kemper Waterproofing
• 5,000 square feet of new bluestone pavers on pedestals
• 4,000 square feet of new concrete sidewalks and curbs
• 8 skylights restored
