by: DAVID F. ASHTON - Seated before the Multnomah County Board of Commissioners, the ACE Academy graduating seniors described the process they used to design and construct the prototype bench.For the past three school years, students from the Architecture Construction Engineering Academy (ACE Academy) charter school have participated in the new Sellwood Bridge Project in meaningful ways.

When the Multnomah County Board of Commissioners met on the morning of Thursday, June 12, a semicircular wood and steel bench had been assembled before them in the chamber.

“This year, students from the ACE Academy were to design and build four benches to be installed at belvederes on the new Sellwood Bridge,” Multnomah County Chair Deborah Kafoury announced, as the presentation began.

“The project turned out to be a little more daunting than anticipated,” Kafoury continued. “This year, the students focused on the bench’s design, and on building the full scale prototype you see here before you.”

Graduating ACE Academy seniors Jesse Martinez, Rebekah Fast, Taylor Lehman, and Ethan Wells introduced themselves – and then began with a PowerPoint presentation, taking turns telling about all the different aspects of their project.

In the beginning, the students explained, they’d met with representatives of the architectural firm – Safdie Rabines Architects – regarding bench design specified for the bridge. And, they checked in with bridge-building officials throughout the year, as the designed process developed.

The students described why they modified the original architects’ design to strengthen the bench. And, they added arches between the legs on the bench, and rounded the armrests to complement the arches of the bridge.

As part of establishing a design and building process, the students calculated time and material price estimates, and made a detailed cost analysis. They applied math skills when making scale drawings, performing calculations to make sure the benches would fit appropriately.

And they applied other skills for stress testing bench frames and joints, and analyzing the types of welding and wood stain that would be best for the environment.

The Multnomah County Commissioners applauded both the students’ diligence and their final project. Commissioner Judy Shiprack commented, “I am really in awe!”

The project’s supervisor – also an ACE Academy math instructor – Doug Mella looked pleased, both with the prototype and with his students’ presentation. “This is a real-life project, giving our students real-life experience that an architect and engineer would go through. It’s been an extremely valuable experience for them. They did a great job.”

A new team of seniors will use the prototype to actually build the four permanent benches during the 2014-2015 school year. The benches will be in place when the new bridge opens in the fall of 2015.

As the county commissioners moved on to other business, Sellwood Bridge Replacement Project Manager Ian Cannon commented to THE BEE, “The bench design is awesome. We’re already looking forward to having those on the bridge.”

About the overall project, Cannon said the contractors are making good progress. “We’re at about the 60% mark on the project – and pretty much on schedule and on budget.”
