One West Wilson

One West Wilson Street State Office Building Envelope Repairs

Project Description

The art deco style One West Wilson – State Office Building was constructed in three phases (1932, 1938 and 1957) and is listed on the National Register of Historic Places. The Project goal is to remedy long term moisture infiltration problems, repair damaged building envelope components and prevent future building envelope deterioration.

Project scope includes a forensic investigation of the granite / structural clay tile and face brick / structural clay tile composite wall systems (including mortar analysis) and window / metal spandrel panel systems to determine the sources of moisture infiltration, level of deterioration of wall system components and verify the existing construction details. Repair and restoration work includes cleaning of the granite, terra cotta and face brick masonry, granite and terra cotta repairs, comprehensive repointing of the facade, restoration of ornamental metal spandrels and window framing, repair of deteriorated embedded steel anchorage and support components, and complete window replacement to replicate the original historic profiles.
