Program Acceleration Risks
• Worker Safety and COVID-19
– Project is underway and has approved COVID-19 safety plan
– Work does not require additional contractor staff. Normal project
work is scheduled for spring and fall to avoid summer airfield
impacts. Due to decrease in operations, contractor can keep their
crew on the job, working through the summer
• Return of Airfield Activity
– Acceleration work is phased with multiple off-ramps to allow “return
to service” of areas if needed by operations
