JTM builds ‘visual mock-up’ of The Jack building’s skin

November 04, 2021

The tower crane isn’t the only thing rising at The Jack jobsite along Alaskan Way South — JTM Construction is building a two-story “visual mock-up” of what the future office building’s facade will look like. The rest of the project, officially at 74 S. Jackson St., is mostly a hole at this point.

Ben Coffman, JTM vice president, said the visual mock-up has two benefits: it gives the architect and owner an idea of what the facade will look like; and it helps JTM with constructability issues, such as how materials go together. He said the architect and owner can make modifications based on the mock-up.
