In the 13 years since philanthropist Paul Allen initiated the Allen Institute to study the human brain, the nonprofit has expanded its focus. The 270,000-sq-ft Allen Institute in Seattle brings together the Allen Institute for Brain Science, the Allen Institute for Cell Science and the Paul G. Allen Frontiers Group into one facility.
The seven-story structure features a variety of labs and offices that petal out from the center atrium that designers say was an effort to encourage collaboration and interaction among the researchers and other professionals.
团队合作对于克服项目遇到的挑战至关重要。为了实现合作概念的承诺，克服脱水和结构性挑战，并保留历史遗址，法官选择了艾伦学院作为本年度西北大学的项目，也选择了高等教育/研究类别的最佳项目。新利luck
Historical Structure
The Allen Institute is a state-of-the-art research institution, featuring wet and dry labs, a data center, an education center and an electron microscopy area. The institute also includes such aesthetic features as artwork incorporated into the building’s exterior and a giant digital media wall.
The facility is also a slice of the past, too, as the structure is built around the former Ford and Pacific McKay car showrooms. Both structures were designated as historical sites in 2006. The team made painstaking efforts to incorporate the old terra-cotta facade into the new facility as a counterpoint to the digital media wall: 545 unitized curtain wall panels with digital media depicting shifting neuron images.
先锋砖石cataloged and disassembled all elements of the terra-cotta facades and put them into storage along with some interior components of the Pacific McKay building that were also landmarked, including some storefront elements and interior plasterwork. The firm then reconstructed the elements using a virtual model made by a laser-based point cloud scan that was taken prior to the deconstruction.
GLY Construction, the general contractor on the project, was then able to use that data to create a 3D model prior to reconstruction, ”to make sure the structure, the ties and all the backup systems behind the block were going to work,” says Tyler Tonkin, principal and senior project manager at GLY.
帕金斯+将架构师在项目BOLA Architecture + Planning was the historic preservation architect. Coughlin Porter Lundeen was the structural and civil engineer.
Dewatering
由于它与联盟湖联盟相近，因此该项目向设计建造团队提出了独特的脱水挑战。矿物弹簧在新生的发掘过程中起泡，引起潜在的结构问题。
“This project was challenging in that the site had many different forms of temporary shoring and ground improvement measures, not to mention that the deepest part of the excavation down to the P4 garage level is 34 feet below the water table,” says Tonkin.
Gly在整个现场创建了一个深层脱水井的系统，该系统旨在清除和处理每分钟300加仑的水。这些井一直在工作，直到团队在地下水位下方约28英尺处的P3停车位时遇到水，并不得不将其脱水和水处理设施的大小翻倍。最大的努力，该系统每分钟卸下大约590加仑。
The team also had a water treatment strategy in place in which water flowed through an electric coagulation system, polished by carbon, and then instead of putting the water into the city’s stormwater system, it was sent into Lake Union in a cleaner state than the existing lake water.
“That was a pretty significant win for the project that the (Washington State) Department of Ecology bought off on and was really a big success from a treatment strategy and cost savings perspective,” Tonkin says.
为了解决潜在的围墙问题，该团队利用了最初旨在建模水平表面的修订软件，以分析垂直表面的完整性。它发现证据表明，由于弹簧而鞠躬。该小组发现明确的证据表明，弹簧的位置通过英寸的分数影响了墙壁的完整性，并每周再生图像以确定情况的严重性。
“我们建立了一系列监测上的点ll of the shored walls before [putting the] structural diaphragm of the building in place .... What we were able to do by establishing these points was [make] what was almost like a thermal heat map, but it was producing color ranges based on measured dimensions from a reference point saying whether or not the face of the shoring wall was ‘in’ or ‘out,’” says Tonkin.
在项目的过程中，定期检查表明情况已经稳定，结构完整性不受井的影响。
Mechanical Marvel
The facility features a unique utility model. “What we were looking for is the perfect harmony of how the different spaces could feed off of one another from a utility perspective,” says Brian Antonsen, director of major mechanical construction at McKinstry, the project’s MEP engineer.
数据中心拒绝的热量被管道提供给办公室和实验室的热量，以创造有效的能量转移。此外，实验室由冷束冷却系统提供服务。
冰冷的梁还起作用，可以从实验室中提取热量，以将其推到热量恢复冷却器中，该冷却器会处理低级热量，并将其变成更高的级别热量，以便在辐射面板提供的办公空间中使用。
“The real key there, between the lab and office, is using waterside, more European cooling systems instead of your traditional airside cooling systems,” says Antonsen.
The extensive mechanical systems required by a lab facility were also expedited by multitrade racks. “We pushed advanced prefabrication to the highest extent possible in a lot of the heavy utility areas. We incorporated plumbing, piping, sheet metal, line voltage power, low voltage control systems [and] insulation all on one system in there, which we built in our offsite facility about 10 minutes away,” says Antonsen.
这些架子允许在一个下午安装大约三周的劳动力。这提供了30％的成本，提高了生产率和质量控制，并创造了更安全的工作条件。
Vulcan项目经理Raymond Burdick说：“为建立这种规模和复杂性的委托工作是我见过的最好的。”“在运营的第一年，运营问题最少。”
