The National Park Services requires a contractor to replace the modified bituminous roof and HVAC system located on the Alan Bible Visitor Center Roof. The roof was replaced in 2010 and all the roof surfaces are showing signs of needing replacement as they are near the end of their service lives. Leaks that created damage to internal ceiling tiles have been observed by park staff. This project will replace the roof before it experiences further deterioration that could result in significant failure. The HVAC units are nearing the end of their practical service life and are not very energy efficient.

The units serve the following spaces ¿ Offices including the basement and restrooms (12 ton), Auditorium (15 ton), and Lobby (4 ton), there are 3 small (1.5 ton) mini-split systems serving the elevator machine room, electrical room, and auditorium projector room as well.
