Guess, a construction manager who started working for Balfour Beatty in August 2023 as a service center coordinator, "quickly recognized alarming patterns of negligence in housing maintenance," according to the lawsuit. It hit home when the Guess's ceiling started to crack in February 2024. But Balfour Beatty delayed needed repairs, the complaint alleges, and by June of that year, there was water intrusion and mold growth. An independent moisture reading inspection found severe mold contamination.
