Giant Construction Corp. — Nine Willful Trench Violations, Over $1M Penalty, Guam (2024)

Outcome: Giant Construction Corp. of Tamuning, Guam was cited for nine willful and two serious OSHA violations and fined over $1 million after inspectors found workers installing sewer lines in unprotected trenches deeper than five feet at the Palisades Subdivision Project — the company's sixth OSHA inspection for excavation violations since 2014.

Federal OSHA inspectors discovered workers employed by Giant Construction Corp. installing sewer lines in multiple trenches at the Palisades Subdivision Project in Tiyan, Guam that were deeper than five feet without any required cave-in protective systems — no sloping, benching, or trench shielding of any kind. Inspectors also found inadequate means of egress from the trenches.

OSHA cited nine willful violations for the repeated, knowing failure to protect workers in excavations, and two serious violations for the egress deficiencies. The combined penalty exceeded $1 million. The company had been inspected five previous times since 2014, with prior citations including two serious violations and a repeat violation in October 2022. OSHA stated the company had shown a documented pattern of "prioritizing profit over worker protection in dangerous excavation work."

How Crucible Prevents This

Six OSHA inspections since 2014 with recurring trench cave-in violations — including two serious and one repeat from October 2022 — followed by nine willful violations in 2024 represents the maximum-severity recidivism scenario. Giant Construction's $1 million penalty reflects OSHA's use of egregious per-instance citation methodology to hold repeat violators accountable at the individual-exposure level rather than per-incident. Crucible's compliance escalation tracking would have flagged this employer for third-party inspection requirements and worksite advance notification requirements after the 2022 repeat citation.
