Evanston Ecology Center

The Evanston Ecology Center was built on the grounds of the Ladd Arboretum in 1974. The center was created to offer educational programs to the community and is run by the City of Evanston in Illinois.

The original building consisted of a single story masonry structure with a low-sloped wood frame roof. A Plexiglas clad greenhouse was added in 1982, and a two-wythe masonry addition was added in 2004, including a wood framed, cathedral ceiling with a standing seam metal roof.

CTLGroup conducted a capital reserve study including an evaluation and assessment of all MEP, roofing, and grounds. The building’s masonry, windows, soffits and trim were also evaluated. We made recommendations for repairs that would require minimal maintenance efforts and extend the service life of the building and its grounds.

CTLGroup prioritized the repairs, provided the environmental board with cost estimates for the recommended repairs along with a schedule for implementation that extended for over the next 13 years.
