Vertical Access was retained by John Milner Architects to perform a hands-on investigation of the exterior and document existing conditions to assist the project team with preparation of repair recommendations. The assessment informed development of the restoration and preservation plan for the treatment of the exterior wood, cedar shakes, sheet metal flashings, lead-coated copper, and cast cementitious ornament.
The tower and steeple of Christ Church dates to 1754, constructed ten years after the rest of the church was completed. The steeple sits on a square-plan brick tower at the front of the west façade of the church. The base of the steeple, octagonal in plan, has circular windows facing the four cardinal directions, each framed by a pediment supported by consoles with carved human faces. Above the steeple base is the octagonal cupola, with round arch openings at each of the eight facets. Rising from the dome roof of the cupola is the slender spire, which is surmounted by a gilded weathervane. Most of the steeple exterior is clad in wood shingles, with wood trim and ornament. Sheet copper is used for flashings as well as ornamental panels and cladding. The standing seam cornice roof at the top of the masonry tower and deck at the interior of the cupola are lead-coated copper. Four large cast cementitious urns decorate the corners of the top of the brick tower.
Scope of work
