The Denver Zoological Foundation, the nonprofit that operates the Denver Zoo, has filed a lawsuit against the lead design firm BRS Architecture and contractor Vertix Builders over alleged issues with the recently completed $19 million renovation of the zoo's California sea lion habitat. The lawsuit claims the defendants failed to meet original specifications and design standards, resulting in construction delays, additional costs, and ongoing problems with the new Schlessman Shores exhibit that opened in 2025.

Why it matters

The lawsuit highlights the challenges and complexities involved in major zoo infrastructure projects, where animal welfare, public safety, and long-term maintenance must all be carefully balanced. It also raises questions about accountability and risk allocation in large-scale construction contracts involving public-private partnerships.

The details

According to the lawsuit, the design firm BRS Architecture allegedly failed to properly specify the pool water level, caging, hardware, and other key elements, leading to issues like reduced pool size, rusting, and problems with the life support systems. The contractor Vertix Builders is also accused of shoddy workmanship, including water seepage, leaking pools, cracking concrete, and other defects. The lawsuit claims the defendants failed to fix the problems after they were identified and communicate.

  • The new Schlessman Shores habitat opened in June 2025, replacing the previous Northern Shores exhibit that had housed sea lions since 1987.
  • The Denver Zoological Foundation filed the lawsuit against BRS Architecture and Vertix Builders in April 2026.
