Cladding: Extruded Concrete 'Oko' Skin | 15,000 sq. ft. 

Jones Chicago, a 25-story apartment tower in Chicago’s River North neighborhood, features over 15,000 sq. ft. of Rieder Extruded Concrete (‘Oko’ Skin). The tower has an efficient concrete structure enclosed by a hybrid window-wall system and with the Oko skin applied in a randomized pattern, with a two-color mix with 3 sandblasted finishes each color. Metal patterns that conceal the parking deck and the unique concrete texture on the Oko skin panels were both inspired by architectural details from a neighboring landmark Chicago Firehouse. HPA was looking for a sustainable long-lasting product that needed to be strong enough to withstand the demands of a parking structure. Oko Skin was ideal in its durability, and the open joints allowed airflow through the garage. The LEED Gold certified building incorporates a high-performing building envelope and mechanical system, a green roof, and recycled products.

Centerline Fabrication

When the large-scale project went out to bid, Centerline was picked for their ability to meet the required budget and help the architect with multiple renderings and design layout. At the start of the construction, Centerline brought in a supplemental installer and worked alongside them while also consulting on design and installation budget. Together they installed vertical black metal extrusions which spanned from the floor to floor slab. They then attached the Oko Skin panels directly to the extrusions with through-fasteners.
