该团队建造了一项为12亿美元的佛罗里达州通勤铁路项目的32英里长的第一阶段,该项目遭受了多年的政治延误,正经历了一系列独特的协调挑战,以使明年春季的第一列火车搬运。

168.1美元design-build-maintain合同for Phase 1—held by a joint venture of Archer Western Contractors, Tampa, and RailWorks Track Systems, New York City—is transforming an active freight line into a hybrid system that is passenger-centric during commuter hours. The first phase of the total 62-mile SunRail line, which stretches 32 miles from DeBary in Volusia County to Sand Lake Road in Orange County, is about 85% done.

The contract includes reconstructing more than 70 of the section's 96 grade crossings, installing 18 miles of double-tracking and building platforms for a dozen stations. Work also calls for an overhaul of existing signal and dispatch systems.

完成后,该线路采用持续的Amtrak服务,将在白天和晚上处理通勤交通。前系统所有者CSX将继续使用走廊过夜进行货运。

Continuing freight service on a passenger rail project—funded partly by a Federal Transit Administration grant—resulted in the first twist. Both the FTA and the Federal Railroad Administration, which typically oversees freight rail, are involved.

领导建筑工程检查团队HNTB的高级项目工程师Mike Gwynne说:“这不是常态。”“通常,您在同一条走廊上没有两个具有管辖权的联邦机构。”

现在被称为佛罗里达州中部铁路走廊(CFRC)的62英里部分将由佛罗里达州运输部(FDOT)拥有和运营,该部门从未在铁路上运行。那是另一个挑战。

针对7月下旬或9月初的目标,在FDOT工作的庞巴迪将接管62英里长的派遣,CSX在CFRC的任一侧担任职责。HNTB的Gwynne称这种情况为“独特”。

他说:“通常,铁路(不要)在他们不拥有和维护的领土上派遣火车。”

该安排对设计和构建产生了影响。

Start and Stop

The SunRail plan endured years as a political football within the Florida Legislature. Finally, the project began to move forward, and in February 2009, FDOT named the Archer Western/RailWorks joint venture as its apparent low bidder for a design-build-maintain contract. Then, the project stalled. Shortly after his election in January 2010, Gov. Rick Scott (R) suspended SunRail for review.

十八个月后,2011年7月1日,州长宣布了他的批准。在那之后的四天,FDOT发布了第一个通知,以进行设计工作。Archer Western项目经理詹姆斯·拉普(James Lapp)表示,为了进行2012年1月的建设开始,合资企业争先恐后地重新组装了其原始员工,该员工不再到位。

Significant design changes awaited the Archer Western/RailWorks team, working with Parsons Transportation Group, the engineer of record.

拉普说:“他们正在寻求更改控制中心的对齐,车站平台和院子的配置。”“除了桥梁和(某些)撞墙之外,它们或多或少都改变了一切。”
