历史上许多最伟大的职业运动员都在很大程度上判断他们的统计数据。按照这一措施，旧金山大通中心开发项目背后的球员命中了建筑名人堂的数字。
The $1.4-billion, 2-million-sq-ft project, prominently sited on 11 acres in Mission Bay, was delivered on time and on budget after 18 months in preconstruction and 31 months under construction. Nearly 9,800 people worked on the 18,000-seat sports arena, two office buildings, 3.2 acres of public plaza and related infrastructure, logging more than 5.3 million work hours combined.
At peak construction, about 1,500 craftworkers placed up to $2.8 million in work per day. All work was accomplished with a safety record six times below the industry average.
“我们达到了每一个主要里程碑，包括我们说我们将开放竞技场的确切日子，”克拉克建筑集团高级副总裁兼蔡斯中心发展项目总监吉姆·麦克拉姆（Jim McLamb）说。
Chase Center arena, which broke ground in January 2017, opened on Sept. 6, 2019, hosting a concert by Metallica. One month later, the Golden State Warriors played their first preseason basketball game at the center, officially christening it as their new home court.
McLamb credits the team’s playbook, developed during preconstruction, for the project’s success. Clark and joint venture partner Mortenson Construction worked early on every possible detail, ultimately amassing a schedule that totaled more than 36,000 construction activities. The team leveraged a robust 4D model and virtual reality mock-ups to lend more certainty to operations.
麦克兰布说：“每天您计划戏剧，然后您就可以参加计划。”
Mortenson-Clark was tasked with delivering a design vision laid out by Manica Architecture and the Golden State Warriors. Set along the shores of San Francisco Bay, the arena’s design evokes the waves in the bay.
“The building swirls around itself,” says Will Hon, project director at Manica. “There’s no clear stopping or starting point. It’s continual motion.”
实现deliv看起来是不可见的ery or service areas around the exterior. A 925-space parking structure, along with the loading dock, were sited below the arena, requiring extensive excavation of the marshy soils. The low strength and high compressibility of the silty clay was undesirable for foundations. Groundwater also posed significant risks.
“Ultimately, we built a gigantic underground bathtub in the worst soil you can imagine,” Hon says.
为了支持该项目的300,000-cu-YD发掘，Mortenson-Clark设计了一个系统，其中包括1,700个单独的领带和由H-Pile和水泥深层土壤混合[CDSM]截止墙组成的外围。地下CDSM墙壁用不可渗透的障碍物包裹了该地点。支撑物还消除了内部支撑的需求，有助于最大程度地利用现场工作空间。挖掘完成后，该团队进口了经过水泥处理的土壤，为重型设备创造了稳定的工作表面。
Adding to the logistical challenges of working in an urban area, the project was located within three blocks of nine other active construction sites. McLamb says the team relied heavily on its 4D modeling to help guide just-in-time deliveries because the site had no storage space and limited laydown areas.
它也毗邻UCSF医疗中心校园以及医院的直升机飞行路径，这严重限制了起重机和其他设备的高度。在计划钢勃起的同时，该团队使用虚拟型号为起重机的放置和动作动画。该计划确保了两把爬虫起重机可以同时支撑17,000吨结构钢的勃起，体育场和屋顶桁架组件的预制装置。
Chase Center的设计元素中最复杂的是其雨环。独特的金属面板皮肤只需要1/8英寸的紧密公差。该外观由5,500个白色铝制面板组成，它们包围着14个不同平面的竞技场。较小的面板使用二级钢框架固定在24英尺乘8英尺的兆帕固定在外部。总的来说，950兆印度构成了追逐中心的外观。
在旧金山和整个州的高建筑活动和劳动力较低的时期，有200多个贸易伙伴为追逐中心的建设做出了贡献。在可能的情况下，莫滕森·克拉克（Mortenson-Clark）带来了重要的贸易伙伴，以帮助建设前。该团队还向小型企业授予了超过2.45亿美元的建筑合同，获得了574个旧金山居民工作机会，并帮助77名旧金山居民建立了建筑业所需的技能。
“This is the kind of project that local people want to work on,” McLamb says. “They want to be able to tell their children they were part of it.”
