A 93-year-old single-story retail building in downtown Portland is being demolished to make way for a new six-story office building developed by Menashe Properties. Konell Construction and Demolition began demolishing the building this week for general contractor Turner Construction. The demolition is expected to last approximately one more week, at which point crews will begin digging for the quarter-block building’s foundations.

A tower crane will be erected at the site in November, and topping out of the post-tensioned concrete building is expected for May 2017, with core and shell completion slated for mid-August of that year. The LRS Architects and Design Department-designed building will have five stories of office over ground-floor retail, and a basement with M.E.P. systems and bike facilities.

Interface Engineering is the project’s mechanical engineer, Nishkian Dean is the structural engineer, and Shapiro Didway is the landscape architect.
