敏感地保护一个传统的建筑杰作，SFU广场更新实现了大学对创新教育、尖端研究和深远的社区参与的动态整合的愿景。室外中央主干道的升级，是对校园具有重要意义的游行路线，通过对校园户外公共空间的审美更新和改善，大大改善了用户体验。

Sensitive preservation of a heritage architectural masterwork, the SFU Plaza Renewal fulfills the University’s vision for dynamic integration of innovative education, cutting-edge research, and far-reaching community engagement. The upgrades to the outdoor central spine, a processional route of great significance to the campus, have greatly improved user experience by aesthetic renewal and improvement of the campus outdoor public space.

建于1965年的埃里克森/梅西西蒙弗雷泽大学校园是加拿大建筑中最重要的作品之一。广场具有双重功能，既是一个公共空间，又是一个庇护下面的教育空间的屋顶。经过五十年的使用，屋顶的薄膜和饰面严重需要更新。本那比山独特的小气候产生了快速的冻融循环。这种情况和不充分的排水导致原来的陶瓷饰面失效。设计团队采用透水铺装系统和用加拿大花岗岩替换现有的粘土瓦来解决这一难题。

Built in 1965, the Erickson / Massey Simon Fraser University Campus is among the most significant pieces of Canadian architecture. The Plaza serves a double function as a public space and as a roof sheltering education spaces beneath. After fifty years of use, the roofing membrane and finishes gravely needed renewal. Burnaby Mountain’s unique microclimate produces rapid, freeze-thaw cycles. This and inadequate drainage caused the original ceramic finishes to fail. The design team addressed this challenge with a permeable paving system and replacement of existing clay tiles with Canadian granite.

旧金山大学标志性的本那比校园规划的最初创建是一个真正的综合设计过程。广场和主商场是由Arthur Erickson和Geoffrey Massey设计的，这样由其他公司设计的重要建筑作品–Zoltan Kiss设计的学术四合院、Rhone和Iredale设计的科学综合体、Duncan McNab and Associates设计的剧院和体育馆、Robert Harrison设计的图书馆–将直接插入主要步行干道并形成一个凝聚的整体。近55年后的今天，更新涉及到许多公司并肩工作在校园的不同部分，目的是在他们的努力中取得一致，延续当时的精神和愿景。

The original creation of SFU’s iconic Burnaby campus plan was a truly integrated design process: The Plaza and Main Mall were designed by Arthur Erickson and Geoffrey Massey so that the significant architectural pieces designed by other firms – the Academic Quadrangle by Zoltan Kiss, the Science Complex by Rhone and Iredale, the Theatre and Gymnasium by Duncan McNab and Associates, the Library by Robert Harrison – would plug directly into the main pedestrian arterial and form a cohesive whole. Now, nearly 55 years later, the renewal involves as many firms working side-by-side on different portions of the campus aiming for alignment where their efforts meet and a continuation of the spirit and vision of the time.

为一个历史悠久的公共空间注入新的生命，开创了更新而不是替换的先例，同时也为后代保留了20世纪60年代的重要文化遗产，其灵感来自于对话、跨学科工作和景观整合的目标。这个项目提供了一个难得的机会来全面改善公共领域，包括更新表面、照明、楼梯饰面、栏杆、场地家具和植物。此外，重建工作尊重了Convocation Mall的正式仪式性质，同时为日常使用者提供了更多的机会，使他们能够聚集、逗留和非正式地联系。

Breathing new life into a historic public space sets a precedent for renewal over replacement and also preserves the important cultural heritage of the 1960s with its inspired goals of dialogue, interdisciplinary work, and landscape integration for future generations. This project provided a rare opportunity to comprehensively improve the public realm, including updates to surfaces, lighting, stairway finishes, railings, site furniture, and plantings. In addition, the renewal respects the formal ceremonial nature of Convocation Mall while providing increased opportunities for day-to-day users to gather, linger, and connect informally.

最小的干预使该项目变得复杂。现有的门、窗和楼梯门槛不允许在现有结构的顶部有超过3.5英寸的堆积。为了支持服务卡车，广场需要一个完全灌浆的，而不是一个传统的，由基座支撑的表面。两层排水系统允许雨水通过表面排水管和透水砂浆系统（环氧树脂和鸟眼砂砾基质）排出，允许水直接流到下面的薄膜上。

Minimal intervention complicated the project: Existing door, window, and stair thresholds allowed no more than 3.5 inches of build-up on top of the existing structure. To support service trucks, the Plaza required a fully-grouted—rather than a conventional, pedestal-supported—finish. The two-level drainage system allows rain-water egress by surface drains and via a permeable mortar system (epoxy and birds-eye gravel matrix), allowing water to run right through to the membrane beneath.

建筑实践正处于解开老化的历史混凝土的复杂性的初期。旧金山大学广场项目帮助推进了以混凝土保护为重点的研究（例如，对全尺寸、原位屋顶组件模拟的性能测试，双层排水，以及新的灌浆材料和系统）。此外，为SFU广场更新开发的设计策略和研究结果支持了其他具有文化意义的战后建筑作品的保护工作，包括其他现代主义校园。这次更新使SFU本拿比校区这一杰作的寿命延长了一倍。

Architectural practice is at the beginning of untangling the complexities of aging historic concrete. The SFU Plaza project has helped advance research focused on concrete conservation (for example, the performance testing of full-scale, in-situ roof-assembly mock-ups, bi-level drainage, and new grouting materials and systems). In addition, the design strategies developed for the SFU Plaza renewal and research results support the efforts of others preserving post-war architectural works of cultural significance, including other Modernist campuses. The renewal doubled the life of the masterwork SFU Burnaby campus.
