Project Description
The work scope includes removal of the existing roof membrane down to the roof deck and replacement with new insulation and a PVC roofing system at Roofs 1-4, and replacement of Roof 5 with flat seam zinc-coated copper roofing. At the transit shutter hatches, the existing east hatch membrane and coatings shall be removed and replaced with new flat seam zinc-coated copper roofing, with the shutter remaining fixed and non-operable, while a new west operable transit shutter shall be created per the drawings. New zinc-coated copper flat seam roofing will also be installed on the transit shutters, upper Roof 5, and dome flashing. Lightning protection shall be removed, restored, or replaced as noted, with continuous protection maintained for the duration of the project, and a new lightning protection system installed at completion. The existing perimeter gutter, downspouts, collection box, and security bracket system shall be removed and replaced with new components in-kind to match the existing profile, gauge, dimension, and material. All exterior metals within the work areas, including dome and deck structural components, wall and roof metals, gutters, cornices, dentils, and dome shutter components, shall be primed and coated with a high-performance coating, and all exterior woods, including decks, handrails, guardrails, stairs, stringers, risers, treads, shutter boxes, gutter boxes, and cornices, shall be primed and coated on all sides and edges as exposed during the work. Masonry work shall include grinding and tuckpointing mortar joints, with existing brick masonry harvested and reinstalled, as no replacements are permitted. A new observation roof deck structure, deck, and railing shall be constructed, with all existing original rail spindles restored and reinstalled and new spindles created to match, together with new posts and newels per the drawings to match existing conditions.
This Project is located at: 901 S Mathews Ave, Urbana, IL 61801
