$80-million lawsuit launched over North Vancouver grain silo collapse

Lawsuit over silo collapse

North Vancouver’s Fibreco Export Inc. is suing the firm that designed and built its new McKeen Avenue grain terminal, alleging shoddy engineering caused one of the silos to collapse last year.

The suit filed in Vancouver Supreme Court on June 4, which names AG Growth International, its subsidiaries Westeel and Union Iron and engineer Donald W. Deal, says the export terminal could face $80 million in losses.

In December 2017, the company signed an agreement with AGT Food and Ingredients Inc. to shift operations to from wood pellet exports to agricultural products, which required them to build new silos, towers, conveyors, and other infrastructure, according to the statement of claim. In March 2019, they signed an agreement with Ag Growth International to design and build the new export facility.

The contract included a guarantee against defective workmanship, design and materials, which AGI and its subsidiaries would have to correct at their own expense, the claim states..

Even before the silo collapsed, Fibro staff began raising concerns about the stability of the associated towers, according to the suit. Fibreco alerted AGI that the structural steel appeared light or possibly under designed.

“It was noted that when standing at the top of the first towers built, there was several inches of sway as people were climbing the stairs,” the claim states. “In response, the AGI defendants represented to Fibreco that the towers and related components were designed to code and that the design was suitable.”

In August 2019, Fibreco hired an outside engineering firm to assess the site, which concluded the towers and catwalks were under designed. Those results were shared with AGI but, still, the company insisted the design was suitable, the civil claim asserts.

During construction in September that year, a welded connection in a catwalk failed, which resulted in work being halted for an investigation.

As a result, AGI took responsibility and committed to do the necessary remediation work, the court documents state.

“As part of AGI’s investigation into the cause of the tower related defects, AGI concluded that Deal had been negligent in the structural engineering and design work he performed on behalf of AGI, Westeel and Union Iron for the agriproducts facility, whereby Deal made a number of critical oversights, errors and omissions in his work, which necessitated numerous structural upgrades to the towers and related components to make them safe and complaint with all the drawings, specifications and applicable codes and standards,” the claim states.

Much of the substance of the lawsuit cites a formal complaint AGI filed about Deal with the Association of Professional Engineers and Geoscientists of B.C. in January 2021.

In that complaint, they said their investigation found Deal designed the towers to standards specifically related to radio towers, which are not applicable to towers at a grain facility. Deal did not adequately understand the software he was working on and the final shop drawings were not reflective Deal’s actual design work, Fibreco cites in the court documents. AGI also stated they found no evidence that Deal ever manually checked any of his computer calculations, “as sound practice would require,” the civil claim states.

“The foregoing was believed by AGI to be an egregious miscarriage of engineering because, had the tower weld connection not broken, it is unlikely that the issue would have been brought to the fore until a much larger and potentially catastrophic incident occurred,” the claim states.

AGI later terminated Deal and he resigned his registration to practice in B.C., according to the suit.

On Sept. 11, 2020, while the siloes were being commissioned, the first one to be fully loaded with grain immediately failed and collapsed, the claim states.
