The Cathedral of the Immaculate Conception

Structural stabilization of main steel-framed spire and reconstruction of four masonry spires atop the Cathedral Bell Tower. Extreme deterioration of original steel framing, jeopardizing the structural stability of the spires (corrosion jacking caused instability of the masonry spires), required the stabilization effort. Completed the following services:

• Design and periodic installation oversight of wood and steel-framed temporary shoring for immediate stabilization of the main spire.
• Design, detailing and development of installation sequence for new structural steel framing for permanent support of main spire.
• Design and detailing of temporary steel platform for support of scaffolding system utilized for masonry repair efforts.
• Design and detailing of stainless steel ties and center anchorage rod for in-place reconstruction of four masonry spires.
