吕元祥建筑师事务所（RLP）一直致力推动建筑设计进入数字化时代，在建筑信息建模（Building Information Modeling, 简称BIM）领域已深耕12载，积累了成熟的专业优势，并运用最前沿的科技为建筑赋能，创造更美好生活。
Ronald Lu & Partners (RLP) is committed to advancing architectural design in the digital age, implementing cutting-edge technologies to create a better life at every opportunity. The 530-metre-high Tianjin Chow Tai Fook Financial Centre (“the tower”; “the Centre”) is an excellent example of the firm’s commitment to excellence.
The seventh-tallest building in the world and the third-tallest in China, this recently-completed tower is a testament to RLP’s extensive skills in using building information modelling (BIM) technology to design and execute world-class structures. In this case, BIM significantly reduced the time and cost of the tower’s construction, and played a vital role in optimising its striking, crystal-clear hyperboloid winding glass curtain wall.
Architects have begun using digital modelling to improve efficiency and accuracy, especially during the design and construction of ultra-complex buildings like the Centre, as it increases accuracy and reduces resource use.

The tallest building north of the Yangtze River in China
The tallest building north of the Yangtze River in China, the Tianjin Chow Tai Fook Financial Centre is made up of four basement levels and five podium levels, topped by a 103-storey tower. The Centre also includes the K11 shopping mall, the K11 ATELIER office, a five-star hotel and serviced apartments.
The Centre has been recognised as one of the most complicated skyscraper designs and structural systems ever designed in the country, combining both rigidity and flexibility to counter the effect of winds and seismic activity. In delivering this incredible “vertical city”, RLP leveraged the sophisticated talents of experts in digital modelling and collaborated with top domestic and foreign partners, including SOM, the East China Institute of Architectural Design and Research and ARUP.

BIM effectively integrates resources and data
以天津周大福金融中心为例，原本8面不规则曲面相交而成的外立面幕墙结构，估计需要至少制造1308块独立不对称的IGU（Insulating Glass Units，即隔绝玻璃模块）。经过BIM分析，反复数据建模，把独立的IGU数量缩减至476块，并提出便于施工的边角分割方法和干挂幕墙节点，项目最终提前4个月竣工，可见BIM在优化过程中起到了至关重要的作用。

At the start of the construction process for the Tianjin Chow Tai Fook Financial Centre, experts estimated that at least 1,308 pieces of independent asymmetric insulating glass units (IGUs) would be required for its unique curtain wall structure, formed by the intersection of eight irregular curved surfaces.
However, after performing BIM analysis and using repeated data modelling, the number of independent IGUs needed for the Centre’s curtain wall was reduced to 476 – a decrease of over 60%. This not only saved an enormous amount of resources and significantly reduced costs; it avoided the risks inherent in fabricating and transporting these glass panels. Additionally, the optimisation of end-unit segmentation and joint cladding helped to further simplify the construction process. As a result of this sophisticated BIM analysis and implementation, the project was completed a full four months ahead of schedule.
Traditional building design still largely relies on two-dimensional technical drawings; BIM extends these designs into three-dimensional geometry. BIM also incorporates information about time, cost, asset management, sustainability, and other important considerations that technical drawings cannot. As the technology has evolved, BIM’s multiple advantages in terms of construction schedule coordination, clash detection, spatial relationships, geospatial information, quantities and properties of building components, and many other factors have become more apparent and increasingly indispensable.

RLP副主席吕庆耀表示: “过去几年，BIM开始广泛在建筑、工程和施工领域（AEC）普及应用，政府亦推出相关标准和政策，大力支持业界加快脚步进入数字化时代。相信未来BIM在整合跨部门信息资源、优化建造时间和经济成本、解决高难度结构方面的优势会更加突显。天津周大福金融中心作为全球瞩目的超高层建筑，拥有精雕细琢的外观造型之余，全程体现了“建造的艺术（art of making）”，可见RLP深耕BIM超12载的执着毅力和专业优势。我们目前拥有超过80位BIM专家，迄今为止已获得近10个BIM国际奖项，包括香港的戏曲中心。未来我们会继续利用数字化技术为建筑赋能，参与更多中国以及世界各城市的蓬勃发展。”
Bryant Lu, the Vice Chairman of RLP, has been a champion of BIM for more than a decade. He says, “Over the past few years, BIM has become widely used in the fields of architecture, engineering and construction. Governments have also introduced BIM-related standards and policies to support these sectors and help accelerate their practices into the digital age. At RLP, we have experienced the many advantages of BIM first hand: integrating cross-departmental information resources, optimising construction times, ensuring economic costs are kept down, and solving complex structures.”
“I absolutely believe that the use of BIM across these sectors will become more prominent in the future”, Mr Lu continues, “BIM helped create the iconic façade system of the Tianjin Chow Tai Fook Financial Centre, making it into a world-renowned skyscraper. This success reflects RLP’s persistence, perseverance and professional advantage in cultivating our BIM proficiency over the past 12 years.”
The Tianjin Chow Tai Fook Financial Centre has already won several awards, including the highest honour recognised by the Royal Institution of Chartered Surveyors’ China Awards 2020, as well as other internationally prominent awards including the China BIM Certification Alliance’s Platinum Award and the Steel Structure Gold Award at the China Construction Metal Structure Association’s Annual Outstanding Engineering Awards.
RLP has also won several international BIM-related awards, including for our design of Hong Kong’s Xiqu Centre. RLP currently employs more than 80 BIM experts, a figure which is likely to expand.
Mr Lu has a bright view of the future of BIM at the firm, saying: “RLP intends to expand our usage of cutting-edge digital tools such as BIM to design a better life and contribute more to the development of cities in China, across the Asia-Pacific region and around the world.”
