In celebration of Colorado Engineers Week (Feb.19-25), the American Council of Engineering Companies of Colorado (ACEC Colorado) is announcing this year’s Colorado Engineering Excellence Awards (EEA) recipients that include 24 design and research projects completed by 19 different Colorado consulting engineering firms.

ACEC Colorado’s EEA competition is annually held between June to October to recognize Colorado consulting engineering firms for engineering design and research that demonstrate an exceptional degree of innovation, complexity, achievement and value.  Eligible projects include those delivered to public or private clients for a range of consulting engineering services, including transportation, structural systems, water resources, building technology systems, environmental consulting, studies and energy. This state competition closely follows entry guidelines established by ACEC National, which invites recipients of Colorado’s Grand Conceptor and Excellence Awards to enter the EEA competition, held in June in Washington D.C.

The 2023 Grand Conceptor Award, representing the highest honor, was awarded to ME Engineers (Highlands Ranch, Colo.) for the Climate Pledge Arena (Seattle). This is the first all-electric sports arena made possible, in part, because of Seattle’s clean electric grid, which utilizes mostly hydro power. In addition to the electrification of the building, ME Engineers devised a novel way for natural air to circulate through the subterranean arena. The innovative solution was the design of massive “snorkels” through which fresh air was piped in from the outside.

The competition’s next highest honors, Excellence Awards, were presented to:

  • Anschutz Health Sciences Building (Denver) by Martin/Martin, Inc. (Lakewood, Colo.);
  • Aspen City Hall (Aspen, Colo.) by IMEG Corp. (Greenwood Village, Colo.);

For more than 50 years, Colorado firms have entered their most innovative design and research projects into the ACEC Colorado EEA competition. This year’s awards judges included representatives from architecture, engineering, construction, education and an industry-related nonprofit. On Nov. 11, nearly 200 guests attended an awards ceremony in Golden, Colo., when the award winners were initially announced. A video about each project is viewable on ACEC Colorado’s YouTube Channel at and more details about the competition are available at
