悉尼弯曲镜面大厦 · AR·MA 的精准参数设计

AR-MA与ARC Roofing 和 Craftmetals再次合作完成了不锈钢立面系统的设计，装备和安装工程。这栋位于乔治街225号的建筑，以其镜面效果的外立面，成为这条街道的独特标签。

AR-MA worked with ARC Roofing and Craftmetals to design, fabricate, and install the stainless steel façade system for architects Harry Seidler and Associates’ recent plaza redevelopment of Grosvenor Place.The façade, which sweeps the expanse of the new development at 225 George Street, reflects the surrounding high rise buildings in its mirror surfaces, providing a marker for Seidler’s iconic building at street level.

在整个设计中，AR-MA保持了基于制造的参数模型，整合相关的建造和材料限制。使模型始终保持与设计的实时更新，并时刻提供视觉反馈。项目从对3D建筑混凝土的云调查开发，所有152个嵌板的制作文件直接从该模型输出，并辅以常规方式起草施了工文件。 每个独特的不锈钢复合面板都通过各种制造工艺进行标记和追踪，并进行多重包装，最终运往现场装配。

Throughout the design, AR-MA maintained a fabrication-based parametric model integrating relevant architectural and material constraints. This model was kept up to date with design changes, and used to provide feedback in regards to visual and financial concerns. developed from a 3D point cloud survey of the as-built concrete. Fabrication files for all 152 panels were output directly from this model, aided by construction documentation drafted in a conventional manner. Each unique stainless steel composite panel was tagged and tracked through various manufacturing processes with multiple contractors, ultimately being assembled for site installation.

AR-MA负责在建成混凝土外墙设计立面系统，并采用3D云调查来准确管理外墙面板与其后混凝土之间的关系。 混凝土外墙与立面系统之间的距离可以通过可调节支架控制，以使混凝土的曲线与外墙的预期位置保持稳定的差异。 AR-MA保持了一贯的高水平精度，通过智能子结构设计来平衡混凝土设计公差。AR-MA的设计令该建筑大放异彩。

AR-MA’s consultancy services included designing the façade system to as-built concrete, employing a 3D point cloud survey to accurately manage the relationship between the façade panels and the concrete behind. Anticipating a large tolerance in the as-built concrete, the façade system was detailed with adjustable bracketry to allow for discrepancy between the curve of the concrete and the desired set-out of the façade. This allowed AR-MA to maintain a high level of accuracy where required, compensating for tight concrete design tolerances with intelligent sub-structure design. AR-MA’s proficiency allowed Harry Seidler and Associates to realise an iconic project in Sydney’s centre, adding to the already rich work of the late Seidler at Grosvenor Place.
