Close calls mar Ottawa's LRT project

The latest incident at an LRT construction site in Ottawa is raising fresh concerns about workplace safety as crews bear down to finish the $2.1-billion project on time.

'We may not be so lucky next time,' union boss says after latest incident at LRT construction site

The latest incident at an LRT construction site in Ottawa is raising fresh concerns about workplace safety as crews bear down to finish the $2.1-billion project on time.

On Wednesday a crane operatorjumped from the machine's cab as it crashed to the groundat the eastern portal of the train tunnel near the University of Ottawa.

No one was injured, but workers told CBC News they were shaken, calling the incident another "near-miss."

A cement mixer being hoisted by the crane fell down a shaft to the tunnel floor, and the crane's boom landed near scaffolding that workers used to access the tunnel.

The president of the Ottawa and District Labour Council, Sean McKenny, worriedsomeonecould have been killed.

"I think we're lucky this time," said McKenny."We may not be so lucky next time."

There have been a number similar incidents since work on the project began. Some have made headlines, others have not. Here's a summary of incidents uncovered by CBC.

Truck piston smashes through cab

On March 12, 2017, a dump truck was unloading inside the LRT tunnelwhenthe hydraulic lift mechanism failed, sending a piston"through the operator cabin, causing the hydraulic fluid to spill," according to the Ministry of Labour's report on the incident.

It sounded like a gun went off. As soon as it broke, it blew fluid everywhere.- Witness to March 12 incident

A worker who witnessed the incident told CBCthe piston drove itselfinto the middle of the cab, centimetres from where the driver was sitting.

"It sounded like a gun went off," the worker said. "As soon as it broke, it blew fluid everywhere."

CBChas agreed to protect the identitiesof that worker and others because they signed a confidentiality agreementandfear they could lose their jobs.

Bridge collapse

On Feb. 19, 2016, a portion of a bridge collapsed on top of heavy equipment at the BayviewLRT construction site. Crews were demolishing the overpass when "it collapsed onto an excavator," according to the Ministry of Labour.

A worker who was there at the time said it was lucky theoperator wasn't crushed.

"It almost killed him. If he had've swung right he would have been dead, no doubt about it," the worker said.

The Ministry of Labour saidno one was injured,but equipment was damaged.

Sinkholes

Moments beforea portionof Rideau Street fell into a large sinkholeon June 8, 2016, an OC Transpobus full of passengerspassedover the area. The collapse also swallowed an unoccupied van and three lanes of roadway.

A report released earlier in April found ongoing work on the LRT tunnel below, combined with the volatile nature of the ground in the area, was the likely cause of the collapse.

The site on Waller Street where the crane collapsed Wednesdayis the same spot that saw an earliersinkholeon Feb. 21, 2014.That chasm waseight metres wide and 12 metresdeep, and sparked some of the earliest concerns about safety on the project.

"I think we are very fortunate there were no injuries associated with the incident," saidthendeputy city manager NancySchepersat the time.

Concrete mishap

On Nov. 10, 2016, rescue crews raced to the same location to help three workers involved in an incident inside the tunnel.

Officials said at least one of the workers was in a basket spraying concrete on the tunnel wall when the material failed to stick and fell.

The metal mesh on the tunnel wallbuckled and got tangled in the basket.Oneworkersuffered a hand injury, paramedics said.

The Ministry of Labourinvestigated another "electrical equipment failure/explosion" on Nov.7, 2016.

"A short circuit occurred within a traction power substation. A flash was created and exited the venting at the bottom of the panel," according to the Ministry's description.

Fire inside tunnel

A fire broke out inside thedowntown tunnelon June 4, 2016 at Parliament Station at O'Connor and Queen streets.The Ministry of Labour told CBC it was notified about the fire two days later.

Nobody was hurt in the incidentbut someworkers and former workers have contacted CBCto say they're concerned about health and safety on the project.

"There was a fire and there were no hoses to put it out," said one former worker, who asked not to be named.

Information provided by workers has been verified by CBC.

Officials preach safety

Following Wednesday's crane mishap, transit boss JohnManconitold reporters he's leaving nothing to chance.

"I don't want to mix luck with safety because safety is a culture, safety is asystem," saidManconi. "There are laws protecting those employees working on this site, and any site in Ottawa."

The technical directorof theRideauTransit Group (RTG), the consortium building the light rail system, also insistedsafety is a priority.

"As far as industry standard is concerned we are bettering industry standard," said RTG technical director PeterLauch."It's a construction site, it's a tough place to work at times. But still, having said that, we stand by our safety record."

The Ministry of Labour said itissued 150 work orders to RTGbetweenthe end of September 2016 andmid-March 2017, which it said is an average number for a project thatsize.

The vast majority of the orders issued concerned the tunnel rather than above-ground work.

RTG said 11 people have had to take time off work due to injuries sustained on the job, a record the consortium said rates better than the industry standard.

No workers have been killed on the project, which is due for completion in 2018.
