What is a void and how did it bring Brisbane’s CBD to a standstill?

Towering cranes and scaffolding dominate inner-city Brisbane right now with major infrastructure projects like the Cross River Rail, Brisbane Metro and Queen’s Wharf set to change the face of the CBD.

The developments are also occurring in some of the oldest parts of the city.

Then on Wednesday morning, traffic gridlock and hours-long delays gripped the CBD after contractors working on the city’s new bus network, Brisbane Metro, discovered a “void” below Adelaide Street.

Brisbane City Councillor Ryan Murphy said a decision was made “out of an abundance of caution” to close the stretch between George Street and North Quay, to ensure no vehicles drove over the weak point.

Could this happen again as the city develops?

This is what those in the know say about what could have caused the “void” and the likelihood of it happening again.

What is a void and how common are they?

Put simply, it’s a hole.

Professor David Williams, director of the Geotechnical Engineering Center at the University of Queensland, said in this instance a void “is a loss of support below the ground surface leading to surface settlement”.

“Most people would agree it’s not that common, we don’t usually have the whole of Brisbane brought to a standstill because … a void is revealed,” Professor Williams said.

“It’s more likely a bit of a one-off — it makes sense that it’s related to the construction activity.”

A void is also referred to as “ground subsidence”.

It can cause major disruption to roads, resulting in fracture, unevenness, and in some cases, sinkholes.

What happened under Adelaide Street?

The exact cause of yesterday’s void is yet to be determined, but Mr Murphy said it was “uncovered through excavation works”.

“We don’t know how long it was there, we don’t know exactly the cause.

“Workers were doing vacuum excavation … which found a void below one of the traffic lanes on Adelaide Street,” he told ABC Radio Brisbane.

“Some free-flowing material … flowed onto our work site which caused a slight sag in the road.

“Essentially a void [was] created, and that void needed to be filled before we could safely reopen that road – this is not a tunnel collapse.”

Professor Williams said “it’s a little unclear” whether the “excavation activity revealed or caused the void.”

What could have caused a void?

Tom Brown from the Rail Tram and Bus Union questioned Brisbane City Council’s explanation.

“The story doesn’t seem to stack up to me, because if there was a void underneath Adelaide Street surely the city’s engineers would’ve picked it up with the ultrasounds when they were marking up this job,” Mr Brown said.

Washington— Republican Rep. Jackie Walorski of Indiana was killed in a car crash Wednesday, the Elkhart County Sheriff’s Office said.

Sheriff Jeff Siegel said Walorski, 58, was in an SUV traveling southbound when it was hit head-on by another car just after 12:30 pm All three occupants in one of the cars — Walorski, her district director Zachery Potts, 27, and communications director Emma Thomson, 28 — died as a result of their injuries.

The sole passenger of the other car involved in the crash, which was traveling northbound, was also pronounced dead at the scene, according to Siegel.

An investigation by the Elkhart County Coroner’s Office and sheriff’s office is underway.

Walorski was elected to represent Indiana’s 2nd Congressional District, which includes South Bend, in 2012 after serving three terms in the statehouse. She was the top Republican on the House Ethics Committee and served on the Ways and Means Committee.

House Minority Leader Kevin McCarthy confirmed Walorski’s death in a tweeted statement from her office, noting that her husband, Dean Swihart, was informed the congresswoman had been killed in the collision.

“She has returned home to be with her Lord and Savior, Jesus Christ,” McCarthy said. “Please keep her family in your thoughts and prayers.”

Tributes for Walorski quickly poured in from elected officials on both sides of the aisle and members of Indiana’s congressional delegation.

Rep. Kevin Brady, the top Republican on the Ways and Means panel, said the congresswoman was “the ‘happy Hoosier’ who would light up a room with her joy, passion, brilliance and love of life.”

“There is nothing [Walorski] couldn’t do,” I tweeted.

Rep. Carolyn Maloney, a Democrat from New York, said on Twitter she is “absolutely heartbroken,” and “my heart goes out to the families of each of the victims,” ​​while fellow Indiana Rep. Jim Banks praised Walorski as a “true public servant — selfless, humble, and compassionate.”

“From my first day in Congress, Jackie showed me kindness and grace,” he said in a statement. “She had a heart of gold, and I will miss her dearly.”

Former Vice President Mike Pence, who also represented Indiana in the House before serving as governor, said he and his wife are praying for Walorski’s family, and the families of Potts and Thomson.

“She served Indiana in the statehouse and the Congress with integrity and principle for nearly two decades and will be deeply missed,” he said in a pair of tweets.

Indiana Sen. Todd Young tweeted that he is “truly devastated” by Walorski’s death and said she “loved Hoosiers and devoted her life to fighting for them. I’ll never forget her spirit from her, her positive attitude, and most importantly her friendship from her. “
