ABSTRACT The Centre Block in Ottawa is a classified federal heritage building housing Canada's parliament. Nearly a century after its formal opening, it closed in 2019 for a decade-long rehabilitation. This neo-gothic building will undergo complete structural, engineering, seismic and security upgrades while preserving its heritage character and materials. The lessons learned during the rehabilitation of other classified buildings in the Parliamentary Precinct have led the proponents of the Centre Block rehabilitation to adopt an integrated approach using ‘Design Assist’ to bring conservators directly into a critical role in the schematic design and design development. In a complex, fragile and highly visible project like this, the public perception of risk to heritage assets is unparalleled. This paper explores the ways in which Design Assist departs from the traditional Design Bid Build model to integrate 17 expert conservation specialisms with the architects and the construction authority. Case studies will be used to illustrate the value added by this innovative conservation-construction model.

Conservation Design Assist：在加拿大议会中心大楼的重大修复中整合保护专业知识的创新模型

摘要 渥太华的中心街区是加拿大议会的归类联邦遗产建筑。在正式开放近一个世纪后，它于 2019 年关闭，进行了长达十年的修复。这座新哥特式建筑将进行完整的结构、工程、抗震和安全升级，同时保留其遗产特征和材料。在议会辖区其他机密建筑修复过程中吸取的经验教训促使中心街区修复的支持者采用“设计辅助”的综合方法，使保护人员直接在方案设计和设计开发中发挥关键作用。在这样一个复杂、脆弱且高度可见的项目中，公众对遗产资产风险的看法是无与伦比的。本文探讨了 Design Assist 以何种方式脱离了传统的 Design Bid Build 模型，将 17 位保护专家与建筑师和施工当局相结合。案例研究将用于说明这种创新的保护建设模式所带来的附加值。
