ARAŞTIRMA DOSYALARI


Background


According to
Schnabel Engineering:


In
2005, settlement and lateral movement of the North Plaza and the Ashlar Seawall
prompted the National Park Service (NPS) to close a portion of the Jefferson
Memorial due to public safety concerns. Schnabel was commissioned by NPS to
analyze the problem and develop a repair strategy. [They] conducted an extended
settlement study to determine the cause of the seawall and North Plaza
movements and the rate of settlement. The problem was in large part due to the
foundation timber piles of the seawall not extending to bedrock.


Schnabel
conducted a value analysis with NPS to determine the best remedy. The selected
option involved demolition and then reconstruction of the seawall on
48-inch-diameter caissons and 18-inch-diameter steel pipe piles. This $13.5
million project was one of the first in Washington, DC to be funded by the
American Recovery and Reinvestment Act of 2009. The project received an ASCE
2012 Project of the Year Award from the National Capital Section.


In 2016, I
filed a FOIA request to see documentation relating to the project. Below, you
will find a breakdown of the records that came in from the National Park
Service (NPS).
