Rising to a height of 284-feet, this record-breaking project sets a new bar for tall timber construction. With 19 stories of timber residential space atop a six-story concrete parking podium, the 273,000 square foot residential tower provides 260 residential units featuring exposed timber columns, beams, and ceilings. The project received a U.S. Forest Service Wood Innovation grant for its unprecedented use of timber in high-rise construction in the United States.
Ascent was permitted by the City of Milwaukee as Type IV-HT construction with variances for height, area, and number of stories. Through a performance-based fire design, the structure is designed to meet the fire and life safety requirements of Type I-A construction, with a 3-hour fire rating for the primary structure and a 2-hour fire rating for the floor system. To validate the design of exposed timber structure at this height, Timberlab facilitated the testing of glulam columns to receive a three-hour fire-resistance rating – a test that had yet to be conducted anywhere in the world.
