The company that designed the latest “raising of the dam” at Mount Polley’s tailings pond says its work was incomplete when the breach occurred earlier this month.

In a statement, AMEC confirmed to 24 hours it is the engineer of record for the latest project to raise the dam.

“While AMEC serves as the engineer of record on the most recent raising of the dam, implementation of the AMEC design has not been completed and some construction activity was still taking place to complete our design,” the company said.

“Investigations at or near the breach are currently prohibited due to safety concerns and we are awaiting the results of field surveys by Imperial Metals to determine the status of dam construction at the time of the breach.”

AMEC did not answer further questions on why the dam needed to be raised, or how long the work was supposed to continue.

B.C. government has said Imperial Metals had failed an assessment in May that found water levels at the pond were too high.

But the company, the government said, returned to compliance shortly after and it’s unclear what relation, if any, that incident had to the work AMEC conducted.

Imperial Metals did not respond to 24 hours questions by press time.
