Hundreds of high school students and young adults in the Detroit area are expected to attend an upcoming skilled trades exhibition and job fair in Eastern Market.

Detroit-based Sachse Construction is putting on the Oct. 22 event for the fourth straight year. It will feature 40 different demonstrations from contract workers, such as masonry, carpentry and plumbing. The event, called the Sachse Construction Academy, aims to drum up excitement for the skilled trades amid a shortage of people to fill those jobs.

New this year, the event will also include a job fair geared toward 18-24-year-olds from Detroit and surrounding areas. Around 40 companies will have human resource representatives on site to answer questions and help job-seekers fill out applications. They are looking to fill a total of 50-75 jobs, said Jill Brack, head of community engagement and strategic partnerships for Sachse.

Todd Sachse, CEO of the construction firm, said the event started four years ago when the company was planning a 25th anniversary party. It occurred to executives that planning efforts could be shifted to something more productive.

“Why don’t we figure out what our industry needs and how we can give back to the industry,” he said.

The construction company produces the event, which costs about $50,000 each year — funded by its annual summer golf outing, Brack said. It has grown to include more companies each year. The company partners with area nonprofits, including its school liaison Junior Achievement, Grow Detroit’s Young Talent, Detroit at Work, SER Metro-Detroit and Southwest Solutions, to locate students and young adults who can benefit from the program.

Southeast Michigan, and Detroit in particular, has seen a development boom in the past few years with high profile projects such as the Hudson’s site tower and Monroe Blocks by Dan Gilbert and Fiat Chrysler Automobiles’ $1.6 billion conversion of its two Mack Avenue engine plants into an assembly plant. These massive projects are forced to compete for skilled labor from a shrinking pool of qualified workers.

More than 500 students — most from high schools in the city of Detroit — will attend the skilled trade demonstrations. The job fair is open to all those interested in learning more about job opportunities. The event will be held in the market’s Shed 3. The demonstrations run from 10 a.m. to 1 p.m., and the job fair goes from 1 to 3 p.m.
