Emergency stop 24/24

Year of completion: 2014 to 2017

Value of work: $2 million contract / $1 million annual planned shutdown

Challenges Met

Carry out the work within the agreed upon schedule and quickly react to the unexpected need for additional work (that had not been considered beforehand) without adding men for labour.
