The Armory has two barrel-ended facades at its east and west ends, enclosed with stucco arches and wooden window walls. These systems are over 100 years old and require replacement. The arches consist of several stucco systems, including those at the face, soffit, piers, and interior areas, which shall be repaired and replaced in-kind as shown. The existing window wall system shall be replaced with a compatible thermally broken aluminum window system that matches the existing historic profiles of the original system. The majority of work must be undertaken from the exterior to minimize impact on interior mezzanine-level MEP systems and scaffolding impacts to adjacent spaces. The scaffolding diagram is proposed to limit work on the existing low capacity perimeter roofs and disruption to new roofing at the east side.Refer to Division 01 of the technical specifications for a complete, detailed breakdown of the base bids and alternates for this project.
