Four construction workers have sustained minor injuries after a section of shoring collapsed at a construction site in downtown Redmond Friday morning.

The incident occurred at 11:45 a.m. in the 16400 block of Cleveland Street and is the site of a six-story mixed-use development called Centerpointe. The size of the shoring that fell has not been determined, but Redmond Police Department (RPD) spokesperson Jim Bove said it fell about 30 feet.

“I heard just a bunch of noise — metal parts falling,” said a City of Redmond employee who had been working on a street project nearby.

The city employee said, from what he heard from others on the scene, the construction workers had been pouring in a concrete floor when the shoring, which supports the floor, fell. He said some of the workers were left with a few bumps and bruises and cuts and scrapes.

First responders from the cities of Redmond, Woodinville, Bellevue and Kirkland arrived onsite and blocked the streets surrounding the immediate area. Bove said 164th Avenue Northeast, from Redmond Way to Northeast 76th Street, and Cleveland Street, from Redmond Way to 166th Avenue Northeast, were closed for a few hours. All lanes of traffic are now open.

The workers who were injured were treated at local hospitals and Bove said fire crews and structural engineers examined the site to figure out whether there was anyone left inside the building, which appeared to be cleared.

A firefighter from Bellevue even climbed the ladder of a fire truck to take pictures of the building from above.

In addition to the first responders, the area around the construction site has been filled with construction workers from the site, workers from surrounding businesses and other passersby, trying to figure out what happened.

The Reporter will follow up with additional information as it is made known.
