上个月，一辆自卸卡车拖着砾石从马萨诸塞州昆西市的第二层车库的屋顶掉落，当时驾驶员遵循GPS，试图转向车库的上层。
“When the driver’s GPS told him to make the next left ... he made a huge mistake by pulling into the garage,” where the floor did not have the load capacity to support his truck, says Jim Anderson, inspector at Quincy Inspectional Services Dept.
Quincy police did not release the name of the driver since no charges were filed and there were no injuries in the partial roof collapse that occurred at 11:34 a.m. on Aug. 21, says Sergeant Karyn Barkas. About 50 cars were trapped in the garage from fallen debris.
昆西副消防局长保罗·格里菲斯（Paul Griffith）说，第二天凌晨4点，该卡车从234 Copeland St.的车库撤离。“停车场不安全。”
Following the incident, police evacuated two medical office buildings, one three-stories, the other four-stories, which share a two-level garage, Barkas says. The buildings were reopened at noontime the following day, but the garage remains closed. Both Quincy and the Massachusetts state police are investigating the incident.
巴卡斯说，当驾驶员离开一条无卡车路线进入车库的上层时，他正在跟随他的全科医生。“入口看起来像是第二层层面的停车区……当他从旋转厂驶入炉子布鲁克大路时，他说'没有卡车'被转移到停车场。”
As the driver attempted to turn around, a seam of the roof collapsed under the weight of the truck with the rear of the vehicle falling toward the first floor while the front remained on the top level, Barkas says.
The Quincy Inspectional Services Dept. reportedly moved vehicles away from the collapse using dollies. Two vehicles were damaged.
该部门的代码执法人员肯·伯克（Ken Burke）说，他的代理机构正在调查该结构。它将评估损坏的程度，并确定在重新开放车库之前需要进行哪些维修。
格里菲斯说，事件当晚工作的首席承包商的ESI防水和砖石修复正计划去除混凝土。ESI不愿意评论正在进行的工作。
A source at PEDA Inc., the structural engineer, also declined comment on the incident since its investigation is still underway.
