In 1960, Northwestern University extended its eastern edge 1,000 ft into Lake Michigan because its borders on the west, north and south were so thoroughly built out. The “lakefill” increased the university’s land holdings to 159 acres from 85. In 2011, Northwestern went to the edge again to build a state-of-the-art on-campus practice facility for its football, basketball and soccer teams on one of the few remaining land parcels of the lakefill. The 419,000-sq-ft Ryan Fieldhouse and Walter Athletics Center includes a full-size NCAA football field, two sports performance facilities, three basketball courts, locker rooms and offices for the university athletic department.
该项目包括一座海堤，它使其西边缘遍布海滩和悬臂二楼，延伸到海堤上，欣赏芝加哥天际线的景色。
“We had a very small site for what the program demanded, and that required us to elevate the football field to the second floor of the complex, then cantilever the support for the north side of the field,” says Randy Herbstman, project manager for structural engineer WSP USA.
在这个2.7亿美元的项目的田地上，有十二个246英尺长的盒管拱门创造了一个高高的天花板，同时还为游客提供了湖泊的欣赏景色。足球场的脸有一个42英尺高的玻璃墙，侧向靠近拱门，扭结的手臂支撑着屋顶的边缘。
每个拱门由20英寸组成。由36英寸。弯曲的墙壁厚度的弯曲盒管。计划要求制定拱门的个人资料，以保持埃文斯顿市的屋顶高度要求，并为足球练习提供足够的空间，一年一度的西北舞蹈马拉松和其他计划中的活动。竖立拱门是一个从钢制制造商Cives Steel Co.的印第安纳州Wolcott的六个拱门的两个平行段的预制开始的过程。然后将水平光束段提起到位，并连接到after子。
“安装拱门需要六个序列，并花了一整天的时间。它必须与湖面上普遍的风小心地协调。”赫布斯特曼说。“When [joint-venture general contractor] Walsh Construction and Barton Malow were installing the arches that day, they weren’t quite fitting and I assured everyone that the math didn’t require spacers or shims [and] the horizontal beams would fit exactly into the prefabricated braces. The final lifts got them seated correctly.”
提出以下足球场有两个120年ft-long and 12-ft-deep trusses. Each truss weighs approximately 125,000 lb and allowed Northwestern to have two basketball courts, coaching and athletic staff offices, and recreational facilities in the basement—a prime example of utilizing every square foot available in the already crowded lakeside athletic park.
土木工程师和景观建筑师SmithGroupjjr设计的定制双重曲折海堤必须通过偏转波浪并防止冬季影响建筑物，同时不阻碍结构周围的海滨交通路径，从而保护现场房屋和运动中心免受100年的风暴活动。海堤本身由印第安纳州的预制片段构建，旨在补充建筑师珀金斯+Will设计的玻璃现代外观。
整个计划都被凝结为18个月的时间表，因此西北航空将能够在2017年1月的筹款活动中展示该设施。
“It was a real team effort,” says Hutt Rubio, Walsh’s project manager. “We coordinated every movement on site, whether that was deliveries, steel erection or other activities. Our collaborative approach began during preconstruction. Contractor and subcontractor expectations were communicated, the budget and project schedule were evaluated, and team members fostered relationships that would lead to successful project implementation and delivery.”
ENR Midwest’s Best Projects judges unanimously agreed that the innovative architectural, structural and civil design combined with a seamless collaborative delivery by the joint venture contractor resulted in a masterpiece on Evanston’s lakefront.
