With about 65,000 square feet, the new West Wing contains four major floors, a sub-basement and a mezzanine between the first and second floors.
The first floor is 290 feet above sea level, but excavations for the footings of the new wing reached 240 feet. Paleontologists found evidence of marine life that indicated that 85 million years ago, Goat Hill was a barrier island rising from the Gulf. The soil composition is tightly packed sand as far as the drilling reached.
Heat and air conditioning for the new archival storage space come from a new building a block away. The computerized system keeps temperature at 60 degrees and humidity at 40 percent. The system alerts the building service director 24 hours a day if there is a problem.
During excavation for the site, workers removed 30,000 cubic yards of dirt taken from the site in 3,000 dump truck loads.
Although the new space is part of the archives building, the space is a separate structure that rests on 86 support piers.
While moisture problems plagued storage space in the original building, the new wing has an outer wall to hold back the earth and lower levels to help prevent or make it easier to deal with external water leaks.
