Project consists of the removal of existing exterior vestibules & indicated walkways. New walkways will be placed where demolished. The front (employee only) vestibule will be replaced by a new fixed prefinished aluminum storefront window system. The covered side entrance will be replaced with the same system but have an exterior sliding entrance door opening to the new entry/security Vestibule. All new glazing shall be ballistic resistant. The new Vestibule enclosure will have its existing gypsum board wall system extended to the bottom of the trusses, acoustic ceiling, & insulated. The approximate 1,728 square foot of existing Lobby shall have the entire acoustic ceiling tile system removed including lighting and mechanical grilles & diffusers. The existing HVAC system will be removed from the attic and replaced. A new ACT system will be installed with R-38 fiberglass batt insulation, new LED lighting, grilles, & diffusers. The exterior work includes preparation of the existing outdoor patio to remove the current silicone water-proofing system to be replaced with a new fluid-applied PMMA system. Existing guard rails will be brought up to code with the addition of new fabricated metal picket panels increased the height to 42” as required.
