A culture of caring

AECOM collaborated to coordinate the removal of landslide debris after a hill collapsed in Washington, killing 43 people.

On March 22, 2014, 43 people were killed and 49 homes were destroyed in Oso, Washington, United States, when a portion of an unstable hill collapsed — engulfing a rural neighborhood and sending mud and debris across the North Fork of the Stillaguamish River.

AECOM’s building + places, environment, global support services and water teams collaborated to coordinate the removal of more than 200,000 tons (181,437 metric tons) of landslide debris across 1 square mile (2.6 square kilometers). With safety at the forefront, the team worked more than 16,000 hours in often-adverse weather conditions and in close proximity to more than 30 pieces of heavy construction equipment — achieving zero recordable injuries.

This safety milestone follows comprehensive initial project planning; initial and ongoing training; strong field safety leadership; and attitudes focused on continual improvement, active engagement and caring. As part of this strong safety culture, employees were encouraged to identify, address and correct hazards, risks and at-risk conditions or behaviors with urgency.

“I am so grateful for the teamwork, skills, professionalism, demonstrated safety culture and collaborative approach that we experienced with everyone,” said Danny Wickstrom, Snohomish County’s sheriff deputy in charge of search and rescue, who worked closely with AECOM throughout the project. “The leaders, operators, spotters, and safety and support personnel are all second to none — simply outstanding! Thank you for helping to give back to a family and a community that has suffered so much.”
