Skanska USA大楼是波特兰俄勒冈州健康与科学大学医院6亿美元扩张的总承包商，该医院表示，它正在调查8月12日的事件，其中涉及一场轨道演习，严重伤害了设备操作员。

The operator of the 50-ton Bauer track-mounted rotary drilling rig waspinned in the machine’s cab when it tipped at about 10:45 a.m., according to officials at Portland Fire & Rescue.

Workers were able to place a jack under the cab before emergency responders arrived. The fire department’s technical rescue team then supported the cab with cribbing, to ensure it wouldn't shift on the soft earth, fire officials said in a statement.

“This was necessary to both protect the victim from further injury and to ensure firefighters’ safety while performing this rescue,” says the statement.

Once the cab was supported, firefighters breached the glass of the cab and removed the operator, who was taken to a local hospital. Total time for the extrication was 14 minutes.

Skanska USA Building reports the injured worker, who was not named, is an employee of Pacific Foundation, Vancouver, Wash.

The hospital project involves a 14-story expansion of inpatient services on the site of the former school of dentistry. It is set to ncrease hospital capacity by one-third, to include 184 new beds, 26,000 sq ft for operating rooms and a three-level parking structure.

工作于去年春天开始，将于2026年完成。该项目与最近完成的Elks Childres Eye Clinic相邻，这是Skanska还建造的5000万美元，五层楼的设施。
