STLI-312431, Rehab Exterior Systems of MIB (GAOA)   4

Background
The National Park Service (NPS), Department of Interior (DOI), Denver Service Center (DSC), will be soliciting proposals on a full and open basis from all interested businesses having the capability to perform the work described below. The solicitation will be issued electronically on the Federal Business Opportunities website at www.sam.gov. This is currently an unfunded requirement with a high expectation that funds will be available. When and if funds become available, a contract will be awarded at that time.

Work Details
The project involves rehabilitating exterior components of the Main Immigration Building on Ellis Island, including exterior window finishes, exterior re-pointing, replacing deteriorated clerestory windows, replacing failing skylights, and repairing portions of the terra cotta roof. The project also includes completely replacing all eight non-historic 1980s era clerestory windows that illuminate the Great Hall of the Main Immigration Building. The existing hardware will be removed and salvaged if compatible with the new window systems. The project aims to eliminate health, safety, and liability risks by replacing deteriorated window assemblies with new, safe window assemblies that are more wind and water resistant. It also aims to maintain the visitor experience on Ellis Island by significantly reducing ongoing maintenance of the windows, saving staff time. Additionally, the project will replace the leaking skylight system with a new, water-tight assembly and repoint the Exterior of the Main Immigration Building including upper parts of the towers and the Clerestory.

The park will treat granite surfaces to restore the building’s weather barrier and ensure structural integrity of the stone veneer. Continued deterioration of the building exterior may lead to spalling of brick material and stone components due to freeze-thaw, causing potential hazards of falling debris. The project will also repair and replace portions of the terra cotta roof which has sustained displaced tiles and damage to the plywood substrate. Secure anchoring of terra cotta roof tiles will eliminate potential safety concern with falling debris, and proper waterproofing will prevent further water infiltration.
