Founded in 1964, the World Forestry Center is a nonprofit educational institution that highlights the forests of the Pacific Northwest. The World Forestry Institute and the Discovery Museum, as well as the Train Pavilion, are located in the Center. AAI Engineering has been involved in the remodel and addition of several portions of the Center over the years. The museum reopened on June 30, 2005 after an extensive building and exhibits renovation. The latest structural remodel included new entries and a new 20 foot high canopy walk through the tree tops.
