To deliver the AIRA Residences project in Kuala Lumpur, builders had to overcome the differing challenges of transforming an existing 17-story, 64-unit residential structure built more than 40 years ago into a near replica of the sparkling, brand-new 18-story “twin” they were constructing next to it.

For instance, the design for the new 18-story, 105-unit Tower A structure—which features a facade comprised of glazing with glass fiber-reinforced concrete and aluminum cladding—allowed only limited headroom for MEP installations to accommodate the taller ceiling heights of a luxury residential building.

结果，承包商早期将传统的钢筋混凝土板的结构系统转换为预应力混凝土元素，转身师国际建设项目经理。他补充说：“各交易之间的协调的不断提高”也是保持建设的关键。

At the same time, transforming Tower B—the existing residential structure that was built in the 1970s—into the same modern style of Tower A would generate its own unique hurdles, including the need to match the older building’s exterior and interior details, such as ceiling heights, with that of the new structure.

Tower B’s transformation required removal of the structure’s facade and demolition of portions of the structure down to bare concrete.

此外，承包商需要加强梁，同时还减少现有楼层的深度，以实现与新塔的设计的天花板高度相匹配。

此外，由于塔B塔最初具有更多的角落和角度，而不是新的建筑物的设计，承包商在某些领域扩展了现有的板块，以使旧的结构更加紧密地反映其新建的双胞胎的形状。

Additionally, the owner, project manager and construction team collaborated to implement an award-winning safety program that used FIVE-S lean practices, which help to achieve a cleaner, safer and more organized workplace.
