What’s Happening at MKA

09.28.2018 — We are is pleased to announce that Principal, L. Leif Johnson, P.E., S.E., LEED AP, will be inducted into Building Design + Constructions “40 Under 40” Class of 2018 on November 14! Since 2006, editors have honored 40 individuals each year who are the next generation of rising stars, and to date, 520 AEC professionals form this select group.

Leif is sought out by owners and architects as a design collaborator for his creativity and leadership. While there is a lot of industry conversation about mass timber, less is actually getting built than the buzz would suggest—but Leif, through his ingenuity and focus, is making it happen! A recent notable project of Leif’s is T3 Minneapolis, a 7-story, 268,280-ft² mass timber office building—the first new construction mass timber office building in the United States of this scale. By paying attention to the wood grain orientation and optimizing the design around stresses always being parallel to the grains, Leif coined the term “Fiber Optimized Design” as a fundamental of the project. Building upon the idea of Fiber Optimized Design, Leif is now steering a MKA research effort around dimensional lumber created from laminated bamboo fibers. Leif is an active leader in the Carbon Leadership Forum (CLF), a collaborative effort between academic, design, and construction professionals committed to a lower future embodied carbon footprint of construction.

Leif has led the engineering structural design for the World Trade Center Perelman Performing Arts Center in New York City, NY; T3 Minneapolis in Minneapolis, MN; San Francisco Museum of Modern Art Expansion in San Francisco, CA; and the Nordic Heritage Museum and Seattle Aquarium Ocean Pavilion in Seattle, WA.

07.10.2018 — Congratulations to the project team of 150 N. Riverside in Chicago who was honored with national recognition in the 2018 IDEAS2 Awards for innovative design with structural steel by the American Institute of Steel Construction.

The 54-story office tower at the edge of the Chicago River captures attention with it’s innovative, tapered superstructure design, creating a footprint equal to just 30 percent of the tower’s floor area and below spans across seven active Amtrak lines. Its construction also includes the largest steel sections in the world!

06.09.2018 — Congratulations to the entire Salesforce Tower project team for taking home the top award for SEAOI’s 2018 Excellence in Structural Engineering Awards: Juror’s Favorite/Most Innovative Structure! Chicago Office Leader, Dave Eckmann, P.E., S.E., FAIA, attended the awards banquet on Saturday, June 9 at the Chicago Museum of Broadcast Communications. MKA has been awarded an SEAOI award 16 of the last 17 years!

Salesforce Tower, the tallest building west of the Mississippi based on highest occupied floor, also has the deepest foundations – 310 ft into solid bedrock. The structural design of this building offers wide-open office space with column-free leasing bays and corners and a crown that soars to 1,070 ft, making it the new beacon of San Francisco.

You can see all the winners on the SEAOI website here.

04.18.2018 — MKA’s Jon Magnusson, Sarah Moline, and Rob Chmielowski were honored to accept a prestigious Grand Award at the American Council of Engineering Companies’ (ACEC) Engineering Excellence Awards Gala on April 17 in Washington, D.C. The award was in recognition of MKA’s innovative, engineering design for the 150 North Riverside project in Chicago.

MKA’s design was recognized by ACEC for a number of innovations and engineering “firsts” including the development of a razor-thin concrete central building core structural system. The sloping columns used to create the cantilevers utilized the largest rolled steel sections produced in the world to channel the loads from the tower to the narrow base. In the building columns above the cantilevers, MKA advanced the industry with the use of steel that is 40 percent stronger than has been used in modern buildings and the use of this high-strength rolled steel is a first in the U.S. MKA partnered with architect Goettsch Partners and contractor Clark Construction.

01.19.2018 — MKA was proud to accept the ACEC-Washington Platinum Award for our project – 150 North Riverside in Chicago, IL. The razor-thin concrete structural core allows this 54-story high-rise to be built on a base just 39 feet wide, perched between the Chicago River and an active set of railroad tracks!  Congratulations to all of our engineering colleagues honored at the awards on Friday evening.
