Story

WNC stone masons will utilize system scaffold access provided by Scaffold Resource to perform critical exterior repairs on the Washington National Cathedral. This project includes the designing, engineering, erecting, and dismantling of scaffold systems integrated with the building’s existing buttresses to safely access and restore historic architectural elements. The scaffold configuration is essential to maintaining both safety and functionality throughout the repair process. Scaffolding is currently being installed on the North Elevation, along the north side of the nave—the main body of the cathedral. This area highlights classic Gothic architecture, specifically the use of flying buttresses, which support the structure by distributing the nave and roof loads laterally. These architectural features suffered significant damage during the 2011 earthquake, especially the pinnacles rising from the arched flyers. The scaffold system will provide full access to eight (8) flying buttresses and include working platforms installed every 6 feet 6 inches in height. The platforms will reach all four gablets and pinnacles associated with each buttress, with scaffold heights ranging from 30 to 130 feet. These platforms will ensure safe and efficient access for masons while preserving the structural and historical integrity of the cathedral. Due to the complexity of the site, extensive scaffold grillage systems are required beneath the scaffold legs to adequately distribute loads across the existing multi-level roof elements, including the triforium, a narrow gallery above the nave. These engineered grillage systems are specifically designed to eliminate the need for re-shoring below the roofs—many of which cover occupied interior spaces used for cathedral services and events. To support vertical movement, a scaffold stair-tower will be erected as part of the North Elevation scaffold system. This tower will provide exclusive access to the low roof level and enable workers to ascend and descend simultaneously. It is strictly for personnel access and is not intended for material staging. Overhead Protection (OHP) will also be provided at two key building entryways along the North Elevation. These protective structures will provide a minimum of 8 feet of vertical clearance and are designed to shield building occupants and pedestrians from overhead construction activities, ensuring continued access and safety. To ensure structural stability, push ties and compression ties will be installed inside the buttresses. Neoprene padding will be applied at all tie locations to protect the historic stonework. This internal tie system eliminates the need for conventional exterior ties that could damage masonry and require future patching. Scaffold Resource will continue to work closely with cathedral project managers to ensure the scaffolding remains safe, minimally disruptive, and reliable throughout the course of the restoration work.
