官员们周六表示，上周在南佛罗里达迈阿密戴德县部分倒塌的12层住宅楼的死亡人数已升至24人，121人下落不明，搜救工作因准备拆除剩余结构而暂停。

部分崩溃发生6月24日凌晨1点15分左右，位于迈阿密海滩以北约6英里的海滨小镇Surfside的尚普兰塔南公寓。根据迈阿密戴德消防救援助理局长雷德·贾达拉的说法，海滨综合建筑的136个单元中约有55个被摧毁。从那以后，数百名急救人员仔细梳理希望找到的碎片幸存者。

迈阿密戴德县市长丹妮尔·莱文·卡瓦(Daniella Levine Cava)在周六上午的新闻发布会上说，随着救援工作进入第10天，又有两具尸体被从废墟中拖出。

莱文·卡瓦(Levine Cava)在周六晚上的新闻发布会上说，周六没有发现更多的受害者，由于为拆除做准备，搜救工作在下午4点停止。

她说，拆除剩余结构的准备工作，如钻入柱子，对现有建筑构成威胁。作为预防措施，搜救人员暂时离开了该地区。

市长表示，一旦拆迁队清理完现场，搜救工作将会恢复。她没有明确的拆除时间表，但她说她“希望”这种情况会在之前发生热带风暴艾尔莎方法。

“我们正在尽可能快地进行，”她说。

莱文·卡瓦(Levine Cava)表示，拆除该建筑的合同已经签署，州长罗恩·德桑蒂斯(Ron DeSantis)表示，政府将支付拆除费用，这将“最低限度地”影响救援工作。此前，市长于周五签署了一项紧急命令，授权“为了公共健康和安全”拆除公寓的其余部分。

“这栋建筑太不安全，不能让人进去，”德桑蒂斯说。“这将保护我们的搜救队，因为我们不知道它什么时候会倒塌。”

冲浪市长查尔斯·伯克特说，大楼的其余部分“最早明天”就会拆除。专家们继续在现场评估该建筑将如何被拆除。

伯克特指出，比最初所说的更快拆除大楼的原因是热带风暴埃尔莎的风。

迈阿密戴德县消防局局长艾伦·科明斯基周六表示，拆除将通过“充电”进行，可能使用炸药，而不是破坏球或其他方法。

消防救援负责人说，一块防水布将覆盖已被搜索的区域，并指出残骸的一些区域尚未被搜索。

官员们还表示，一个特遣队的六名救援人员检测出新冠肺炎呈阳性，并已离开现场。

埃尔莎的准备工作正在进行中，埃尔莎早上从飓风减弱为热带风暴，预计周一至周二将在佛罗里达州南部附近出现。

周六，德桑蒂斯宣布几个县进入紧急状态，预计热带风暴埃尔莎将来袭。炎热、潮湿、暴雨、强风和闪电风暴也使救援人员的条件变得困难，迫使他们在最近几天周期性地暂停24小时的工作。

官员们说，周五，当工作人员搜索坍塌区域时，在残骸中又发现了两具尸体。

根据莱文·卡瓦的说法，周四晚上又发现了两具尸体，包括一名7岁女孩的尸体，她是迈阿密一名消防员的女儿。据科明斯基说，消防员不是发现女孩尸体的船员，但他得到了通知。

“不言而喻，从上周三开始的每晚都非常困难，”莱文·卡瓦周五早上在冲浪场的新闻发布会上说。“但昨晚与众不同。对我们的第一反应者来说，这真的很不一样，也更困难。”

与此同时，据莱文·卡瓦(Levine Cava)称，灾难发生时住在公寓里或住在公寓里的191人已经得到解释，他们是安全的。他强调，这些数字“非常不稳定”，“继续变化”。

随着侦探们继续审查据报失踪人员的名单，这些人的人数已经上升，莱文·卡瓦称这是“非常好的消息”。

然而，自该建筑部分倒塌的那天早上以来，在废墟中没有发现幸存者，周五发现更多人活着的希望似乎正在消退。

科明斯基说，救援人员在发现第一反应者自己的女儿后“情绪激动”，这“需要付出代价”。但他说，这不会阻止他们继续寻找仍然失踪的人。

“我只是希望我们会有一些幸存者，”科明斯基在周五上午的新闻发布会上说。

迈阿密市消防救援部门负责人约瑟夫·扎拉尔班后来在一份声明中证实，该小组的一名成员在灾难中失去了他7岁的女儿。

莱文·卡瓦(Levine Cava)在本周早些时候签署拆除该建筑剩余部分的紧急命令时说，此举将“帮助我们快速行动”。

上周，工作人员清理了这座建筑，此后，所有的搜索和救援资源都转移到了废墟上。但这两个地点是并排的，剩余的建筑给试图在残骸中找到幸存者或人类遗骸的救援人员带来了挑战。

“考虑到我们对建筑完整性的持续安全担忧，我们继续限制进入倒塌区，”莱文·卡瓦(Levine Cava)周四晚上在冲浪场的新闻发布会上说。

乔·拜登总统和第一夫人吉尔·拜登旅客多的周四去冲浪区会见官员、第一反应者、搜救队以及受害者家属。回忆起1972年导致他的第一任妻子和一岁女儿死亡以及两个儿子严重受伤的车祸，总统告诉记者:“失去某人已经够糟糕的了，但最困难的部分，真正困难的部分，是不知道他们是否能活下来。”

一座经受了几十年飓风的建筑部分倒塌的原因仍然未知而且是在调查研究中。

官员们说，尚普兰南塔建于20世纪80年代，已经进行了40年的重新认证，当它部分倒塌时，一直在进行屋顶工作——计划进行更多的翻新。

2018年10月的结构性实地调查报告，其中包括数百页的公共文件放周日晚些时候，Surfside镇表示，公寓游泳池甲板和入口车道下方的防水系统出现故障，导致“这些区域下方的混凝土结构板出现重大结构损坏”。

已经代表幸存者和受害者对尚普兰塔南公寓协会提起了一系列诉讼，声称部分倒塌是可以避免的，该协会知道或应该知道结构损坏。该协会的一名发言人告诉美国广播公司新闻，他们不能对悬而未决的诉讼发表评论，但他们的“重点仍然是在这个困难时期照顾我们的朋友和邻居。”

该协会的董事会星期五发表声明说，其幸存的成员“已经得出结论，为了所有有关各方的最佳利益，应该任命一个独立的接管人来监督法律和索赔过程。”

“我们知道，作为全面调查的一部分，答案需要时间，”声明继续说，“我们将继续与城市、州、地方和联邦官员合作进行救援工作，并了解这场悲剧的原因。”

官员们说，在冲浪场大楼倒塌后，北迈阿密海滩市出于与40年重新认证过程有关的安全考虑，下令立即关闭另一栋公寓。

城市官员在一份声明中说，根据对周五提交的重新认证报告的审查，快思聪大厦公寓“在结构和电气方面都不安全”。

“北迈阿密海滩市已经采取了我们建议审查的步骤，以确保及时完成重新认证过程。据我所知，作为审计的结果，他们发现了一栋尚未重新认证的建筑，当信息进来时，他们采取了一些措施，”莱文·卡瓦周五晚上说。

据报道，大约300名居民不得不撤离美国广播公司迈阿密分公司，同时进行全面的结构评估。

这套156个单元的公寓建于1972年。

Surfside building collapse latest: Death toll rises to 24 as search effort pauses during demolition prep

The death toll at the 12-story residential building that partially collapsed in South Florida's Miami-Dade County last week has risen to 24, leaving 121 unaccounted for, as search and rescue efforts paused amid preparations to demolish the remaining structure, officials said Saturday.

The partial collapseoccurredaround 1:15 a.m. on June 24 at the Champlain Towers South condominium in the small, beachside town of Surfside, about 6 miles north of Miami Beach. Approximately 55 of the oceanfront complex's 136 units were destroyed, according to Miami-Dade Fire Rescue Assistant Chief Raide Jadallah. Since then, hundreds of first responders have beencarefully combing throughthe debris in hopes of findingsurvivors.

Two more bodies were pulled from the rubble overnight, Miami-Dade County Mayor Daniella Levine Cava said in a press briefing Saturday morning, as the rescue effort entered its 10th day.

No further victims were found Saturday, and search and rescue efforts were halted at 4 p.m. due to preparations for the demolition, Levine Cava said during a press briefing Saturday evening.

Preparation work for demolishing the remaining structure, such as drilling into columns, presents a threat to the standing building, she said. The search crews have temporarily left the area as a precaution.

Search and rescue will resume once the demolition team has cleared the site, according to the mayor. She did not have a definite timeline for the demolition, though said she was "hopeful" it could happen beforeTropical Storm Elsaapproaches.

"We are proceeding as quickly as we possibly can," she said.

Levine Cava said that the contract has been signed for the demolition of the building and Gov. Ron DeSantis said the state will pay for the costs of the demolition and it will "minimally" affect rescue efforts. It comes after the mayor signed an emergency order authorizing the demolition of the rest of the condominium "in the interest of public health and safety" on Friday.

"The building is too unsafe to let people in," DeSantis said. "This will protect our search and rescue teams because we don't know when it will fall over."

Surfside Mayor Charles Burkett said that the remainder of the building could be coming down "as early as tomorrow."Experts continue on the scene to evaluate how the building will be brought down.

Burkett noted that the push to take down the building faster than originally stated was because of Tropical Storm Elsa's winds.

The demolition will occur via a "charge," likely using explosives, not a wrecking ball or another method, Miami-Dade County Fire Chief Alan Cominsky said Saturday.

The fire rescue chief said that a tarp will cover the area that has been searched, noting that some areas of the wreckage has not yet been searched.

Officials also said six rescue workers from one task force have tested positive for COVID-19 and have since left the scene.

Preparations are now being made for Elsa, which weakened from a hurricane to a tropical storm in the morning and is expected to come near Southern Florida Monday into Tuesday.

On Saturday, DeSantis declared a state of emergency for several counties in anticipation of Tropical Storm Elsa. Heat, humidity, heavy rain, strong winds and lightning storms have also made the conditions difficult for rescuers, periodically forcing them to pause their round-the-clock efforts in recent days.

On Friday, two more bodies were found in the wreckage as crews search the area of the collapse, officials said.

It follows another two bodies found Thursday evening, including that of a 7-year-old girl who was the daughter of a Miami firefighter, according to Levine Cava. The firefighter was not part of the crew that discovered the girl's body but he was notified, according to Cominsky.

"It goes without saying that every night since this last Wednesday has been immensely difficult," Levine Cava said during a press briefing in Surfside on Friday morning. "But last night was uniquely different. It was truly different and more difficult for our first responders."

Meanwhile, 191 people who were living or staying in the condominium at the time of the disaster have been accounted for and are safe, according to Levine Cava, who has stressed that the figures are "very fluid" and "continue to change."

The number of those accounted for has gone up as detectives continue to audit the list of people reported missing, a development that Levine Cava called "very good news."

However, no survivors have been discovered in the rubble of the building since the morning it partially collapsed, and the hope that more people would be found alive appeared to be fading Friday.

Cominsky said rescue workers are "emotional" after the discovery of a first responder's own daughter, which "takes a toll." But he said that won't stop them from continuing to search for those who are still missing.

"I just was hoping that we would have some survivors," Cominsky said at the press briefing on Friday morning.

City of Miami Department of Fire Rescue Chief Joseph Zahralban later confirmed in a statement that a member of the team lost his 7-year-old daughter in the disaster.

Speaking on the signing the emergency order to demolish the remainder of the building earlier this week, Levine Cava said the move will "help us move quickly."

The structure was cleared by crews last week, and all search and rescue resources have since been shifted to focusing on the pile of rubble. But the two sites are side-by-side and the remaining building has posed challenges for the rescuers trying to locate any survivors or human remains in the wreckage.

"Given our ongoing safety concerns about the integrity of the building, we're continuing to restrict access to the collapse zone," Levine Cava said during a press briefing in Surfside on Thursday evening.

President Joe Biden and first lady Jill Bidentraveledto Surfside on Thursday to meet with officials, first responders, search and rescue teams, as well as families of the victims. Recalling the 1972 car accident that killed his first wife and 1-year-old daughter as well as badly injuring his two sons, the president told reporters: "It's bad enough to lose somebody but the hard part, the really hard part, is to not know whether they'll survive or not."

The cause of the partial collapse to a building that has withstood decades of hurricanesremains unknownand isunder investigation.

Built in the 1980s, the Champlain Towers South was up for its 40-year recertification and had been undergoing roof work -- with more renovations planned -- when it partially collapsed, according to officials.

A structural field survey report from October 2018, which was among hundreds of pages of public documentsreleasedby the town of Surfside late Sunday, said the waterproofing below the condominium's pool deck and entrance drive was failing and causing "major structural damage to the concrete structural slab below these areas."

A slew of lawsuits against the Champlain Towers South Condo Association have already been filed on behalf of survivors and victims, alleging the partial collapse could have been avoided and that the association knew or should have known about the structural damage. A spokesperson for the association told ABC News they cannot comment on pending litigation but that their "focus remains on caring for our friends and neighbors during this difficult time."

The association's board released a statement Friday saying its surviving members "have concluded that, in the best interest of all concerned parties, an independent Receiver should be appointed to oversee the legal and claims process."

"We know that answers will take time as part of a comprehensive investigation," the statement continued, "and we will continue to work with city, state, local, and federal officials in their rescue efforts, and to understand the causes of this tragedy."

In the wake of the Surfside building collapse, the city of North Miami Beach ordered that another condominium close immediately amid safety concerns connected to the 40-year recertification process, officials said.

The Crestview Towers Condominium is "structurally and electrically unsafe," based on the review of a recertification report submitted Friday, city officials said in a statement.

"The city of North Miami Beach has taken the steps that we recommended to review to make sure that the recertification process was being done in a timely basis. And as I understand it, as a result of that audit, they found a building that had not been recertified, and when the information came in, they took some steps," Levine Cava said Friday evening.

Some 300 residents have to evacuate, according toABC Miami affiliate WPLG, while a full structural assessment is conducted.

The 156-unit condo was built in 1972.
