Climbing Fragile Church Spire for Restoration
How to Install Netting on a 215-Foot Historical Church Spire

There was only one height access method to protect this historical church.

Contactless height access saved tens of thousands of dollars.

Alpha Platforms was engaged by industrial climbers to help set the netting over the spire on the 1870 Arch Street United Methodist Church in downtown Philadelphia.

There were no suitable and affordable options for getting onto the 215-ft steeple. The team evaluated hiring a crane with a hanging basket, roof hatch access, and scaffolding: they were all too expensive, risky, and would further damage the fragile structure.

Alpha Platforms dispatched its A-300, a 300-ft high access boom lift to hang a net without making contact with the building. Our all-inclusive service provided a full-time IPAF-certified lift operator, a road closure permit, and traffic management for the duration of the project.

The project was scheduled during a major snowstorm and the client hesitated due to the bad weather.

Find out how long it took and whether snow, wind, and sleet affected net installation.
