Northwestern
University Facility
Wins Design Award
The Global Hub, the new home of Northwestern University’s Kellogg School of Management in Evanston, IL, has been awarded the Post-Tensioning Institute’s 2017 PTI Project Award. The PTI Project Awards are given biennially and recognize excellence in post-
tensioning concrete design. Global Hub took top honors in the buildings category.
Designed by Toronto-based ar- chitecture firm KPMB Architects, the 415,000-square-foot Global Hub sits on the shore of Lake Michigan and features an innovative undulating design. To achieve the curving shape and accommo- date various programming requirements throughout, extensive cantilevering and post-tensioning were introduced to mini- mize structural depth and deflection.
The building consists of four six-story concrete “lofts” positioned around two vertically stacked central atriums. The biggest structural challenge was support- ing 169 transfer columns in the upper three levels of the lofts. The transfer columns at the perimeter of the upper levels are set outboard of the levels below, resulting in dramatic post-tensioned

Color Pavement Marking
MMA vs. Thermoplastic
SCHOOLS AND COLLEGES HAVE BEEN
looking for a long-term solution to pavement markings. MMA pavement marking is the most durable color marking material avail- able. It has been used in the U.S. and around the world for decades as line striping. MMA (methyl methacrylate) is now getting a lot of attention as color pavement marking and is becoming increasingly common for bike lanes, bus lanes, crosswalks, pedestrian areas and other markings.
Unlike thermoplastic, MMA does not require special equipment for installation, it is less expensive and can last 5 to 10 years or more depending on the vehicular usage and markings do not need to be redone every season. This makes it an ideal material for campuses that can use their own personnel to apply it. MMA bonds to both asphalt and concrete surfaces; concrete is a challenge for other marking materials.
Known for high durability, increased wet-night visibility, skid resistance and optimal color stability, MMA-based area markings are commonly being used to apply bright red crosswalks. The contrast- ing colors of these crosswalks alert drivers and can significantly reduce the number of pedestrian injuries. MMA green bike lanes serve as a continuous reminder to drivers of the possibility of the presence of bicyclists. Wayfinding and unique designs are also great uses for this durable material that can be made in custom colors.
Pavement markings are primarily a safety feature and can only be effective if they are visible. MMA is UV stable, so the colors stay brighter longer than thermoplastic, and it bonds to itself so it can be refreshed without full removal. MMA can also be applied in tem- peratures ranging from 40-100°F, extending the marking season.
