Perkins&Will’s Damen Green Line Station Brings Elevated Design to a Transit-Deprived Chicago Neighborhood

Chicago’s Green Line, one of the city’s oldest elevated rail systems, has long been a lifeline for transit between iconic landmarks like Frank Lloyd Wright’s Oak Park studio and Hyde Park’s Robie House. However, the Near West Side neighborhood faced a 75-year transit void after a 1948 station closure. This gap, exacerbated by the 1994 opening of the United Center—a 23,500-seat arena—created persistent traffic issues. In 2017, community advocacy led to a partnership with Perkins&Will (P&W) to reimagine the station. The $80 million, 18,200-square-foot facility, completed in August 2024, now serves as a dual-purpose hub for daily commuters and event crowds.

A Long-Awaited Revival

The project’s success hinges on balancing everyday usability with capacity for large gatherings. By transferring city-owned land to CDOT, P&W expanded the station’s footprint beyond typical right-of-way constraints. The result? A grand headhouse with a sweeping stair, escalator, and expansive plaza, designed as a “civic promenade” by P&W’s Ralph Johnson. A secondary entrance with wide pivoting doors supplements main access during peak events.

Designing for Dual Needs

P&W’s solution merges functionality with striking architecture. The station’s bridge—a 130-foot truss of green-painted steel—connects eastbound and westbound platforms, spanning the tracks like a modern-day Chicago bridge. Fabricated in two pieces via barge and truck, the structure is secured with pin connections to north and south towers. Large glass panels with grated openings provide natural light and ventilation, offering panoramic views of the skyline.

Equally notable is the glazed headhouse with a green roof, its white-tapered columns and bird-friendly fritted-glass panels echoing Renzo Piano’s Art Institute addition. A mosaic mural by Folayemi Wilson honors the neighborhood’s cultural diversity.

A Catalyst for Change

The Damen Green Line Station aligns with Chicago’s Connected Communities Ordinance, fostering equitable transit-oriented development. Adjacent projects, like mixed-income housing and the 1901 Project, aim to revitalize the area. As Bryan Schabel notes, “It’s more than just restored train access—it’s a catalyst for reinvestment.”

Tariff Fallout Leads to Layoffs at Massachusetts Concrete Firm

Key Takeaways

  • Mass layoffs due to tariffs: Unistress, a Pittsfield, Massachusetts-based precast manufacturer, cut 233 jobs after contract delays tied to material price volatility. The firm, known for projects like Boston’s Big Dig and Yankee Stadium, is adjusting operations amid rising costs and uncertain timelines.
  • Tariffs disrupting projects: Tariff-driven volatility is sidelining projects and shrinking industry backlogs. Unistress CEO Petricca described the layoffs as temporary but emphasized financial strain from delayed contracts.
  • Material costs soar: Construction material prices rose 0.2% in May, with aluminum and steel leading gains. Annualized prices are up 6%, and June tariffs are expected to push costs even higher.
  • Industry impact: Nearly a quarter of builders reported tariff-related cancellations in May. Backlog fell to 8.4 months, down from a two-year high, while sales and staffing confidence declined.
  • Legal requirements: Unistress filed a WARN notice, requiring advance notice of mass layoffs. The cuts will take effect between July 7 and August 25.

The fallout highlights how global trade policies are reshaping the construction sector. Contractors face mounting pressure as tariffs and inflation erode margins, forcing tough decisions like layoffs. For Unistress, the challenge is balancing operational adjustments with long-term stability.

Detroit Deploys Drones and AI to Target Building Efficiency Improvements

Detroit is leading the charge in smart city innovation by integrating drones and AI to revolutionize building efficiency. Partnering with startups and the tech incubator Newlab, the city launched the Advanced Aerial Innovation Region in 2022 as a testbed for next-gen drone tech. This initiative aims to scale drone solutions from concept to city-wide deployment, addressing challenges like energy retrofits with precision and cost-effectiveness.

Key Innovations:

  • Thermal Deficiency Detection: Drones equipped with thermal cameras identified insulation gaps and water infiltration risks in three municipal buildings.
  • AI-Driven Analysis: Lamarr.AI’s platform analyzed data to create 3D models and energy simulations, pinpointing upgrades that could cut HVAC energy use by up to 22%.
  • Tiered Retrofit Strategy: The final reports offered actionable steps, such as weatherization at curtain walls, window replacements, and roof enhancements.

Expert Insights:

  • Matt Whitaker, director of mobility innovation platforms at Michigan Central, emphasized the “phenomenally high” potential of drone use in city operations.
  • Tarek Rakha, CEO of Lamarr.AI, highlighted the efficiency gains: “Our AI is 10 times faster, 5–10 times more affordable, and 50% more accurate than traditional methods.”

This project underscores Detroit’s commitment to leveraging cutting-edge tech for sustainable urban growth.
