Investigators are now examining the debris left behind. By Dan Krauth, ABC7 New York NEW YORK City records show demolition and construction work had been going on for months next to a 96-year-old Brooklyn building at 1321 Flatbush Ave. that collapsed Wednesday night, killing at least eight people and injuring more than a dozen others. Investigators are now examining the debris left behind to determine what caused the collapse, which shocked residents and left city leaders with unanswered questions.
调查人员目前正在检查留下的废墟，以确定倒塌原因。这起倒塌事件震惊了居民，也让市领导层留下了未解之谜。
Google Maps imagery shows the commercial building that once stood at the adjacent construction site. Compared with chopper video from Wednesday, the neighboring building is gone, and rubble fills the construction site next door.
谷歌地图影像显示，相邻施工场地原本矗立着一座商业建筑。与周三的直升机拍摄视频对比，相邻建筑已不复存在，废墟填满了隔壁的施工场地。
Construction safety expert Glenn Corbett of John Jay College, who has not investigated the site, said excavation work near older structures can present stability concerns. "When you go and dig next to these kind of buildings, there's always an issue of stability," Corbett said.
约翰·杰伊刑事司法学院的建筑安全专家 Glenn Corbett 表示，他在老旧建筑附近进行挖掘作业可能会引发稳定性担忧。Corbett 未参与现场调查。
Corbett said retaining walls, or shores, commonly used to support the perimeter of construction pits, can become a point of concern during investigations. "What was it not built correctly with the size of the members, the wood panels not large enough was the... if there was steel involved, which I believe there was, was that not, was that not up to speed as far as what's required?"
“当你在这类建筑旁挖掘时，总会存在稳定性问题，”Corbett 说。

Corbett 表示，常用于支撑施工坑周边的挡土墙或支撑墙，在调查期间可能成为关注焦点。
According to Department of Buildings records, one summons was issued in April for the construction site along Bedford Avenue.
“它是否建造不当，构件尺寸是否不合要求，木板是否不够大，如果涉及钢材——我认为涉及了——钢材是否未达到要求标准？”Corbett 说。
A stop-work order was allegedly violated but was later resolved.
根据建筑局记录，贝德福德大道施工场地于 4 月收到一张传票。据称曾违反停工令，但后来已解决。
Blueprints show a mixed-use building was under construction at the site, with plans for retail space, medical services and residential apartments. Our sister station WABC found no building violations for the site of the building that collapsed.
蓝图显示，该场地正在建设一座混合用途建筑，计划包含零售空间、医疗服务和住宅公寓。
Corbett said it is important for New York City to understand the cause of the deadly incident.
我们的姊妹电台 WABC 发现，倒塌建筑所在场地没有建筑违规记录。Corbett 表示，纽约市弄清这起致命事件的原因非常重要。
"They've got to find out why did that happen? And do we need to change the rules?"
“他们必须查明为什么会发生这种事？我们是否需要修改规则？”科贝特说。
Corbett said.
WABC 拨打了 4 月份收到传票的承包商名下的电话号码。该承包商表示，公司完成了拆除工作，但已于 4 月底或 5 月初离开工地。他说他不知道护岸存在任何现有状况。对坍塌原因的调查仍在进行中。
WABC called the number listed for the contractor who received the summons in April. The contractor said the company carried out the demolition work but had left the job site by late April or early May. He said he was not aware of any existing condition of the shores. The investigation into the cause of the collapse remains ongoing.
