The Leaning Tower of Dallas was still leaning Monday — but it’s expected to tumble before long.
After Sunday’s implosion of an 11-story tower on Haskell Avenue near downtown Dallas failed to bring down the center of the structure, the lopsided landmark immediately became an internet sensation.
As video of the partial collapse spread, people began posting pictures of themselves pretending to prop up what remained of the former Affiliated Computer Services building.
Sooner or later, the stubborn core, which includes the elevator shaft, will make way for a $2.5 billion mixed-use project called The Central.
Lloyd D. Nabors Demolition said its crews would break apart the building with a crane and wrecking ball this week.
Lloyd Nabors, whose company also demolished Valley View mall, said partial implosions are fairly common.
“These cores can be really tough,” he said. “We did a lot of work to prep for it, but unfortunately it didn’t come over.”
Demolition companies often use a contractor for implosion work. For this project, Pettigrew Inc. created the blast plan and handled the explosives.
“All the explosives did go off, and the structure — that type of construction with the central core and the outer columns — they’re tough, obviously,” said Pettigrew’s president, Steve Pettigrew.
Jake Lindamood of Lindamood Demolition, which took down an Affiliated Computer Services building next door in 2015, said the concrete core of the building that was imploded Sunday needed extra attention.
“At the end of the day, they didn’t prep the building properly, and it didn’t fall,” he said. “The iron collapsed, but the core didn’t.”
Mohammad Najafi, director of the construction management program at the University of Texas at Arlington, agreed that “definitely something went wrong.”
Buildings usually are imploded in a sequence, with explosions timed at short intervals starting from the perimeter and moving to the core, he said.
“I think probably that the delay … didn’t activate when it got into the core of the building,” he said. “That delay process helps with the safety, dust and flying objects. The delay helps it, but it should have come down.”
He noted that the core of a building is designed to resist extreme events, including earthquakes and tornadoes, so it’s possible there weren’t enough explosives in place to knock it down.
Danielle Light was among the people who stopped by to see what was left of the building.
She’d been asleep in her apartment near the blast zone when the noise from the explosions awoke her and her fiance early Sunday.
“We always have driven by it and thought they needed to tear it down,” Light said. “All the windows were busted and it was an eyesore.”
But the leaning building was a sad sight for Richard Allen, who came to photograph what was left of place where he once worked.
As an architect, though, he could envision what lies ahead for the site, where developers plan 5 million square feet of office, residential, hospitality, dining, entertainment and retail space.
“In the next 30 years,” Allen said, “we’ll see something wonderful on this side of the highway.”
