Super tall buildings have become defining features of modern skylines, reshaping cities beyond height alone. They reflect how urban centres express identity and progress, as the complexity of designing and delivering these structures pushes the industry towards new approaches in engineering, materials and construction.

These themes formed the focus of a recent seminar jointly organised by CDL Academy and the Institution of Engineers Malaysia (IEM), which brought together around 80 participants on site, alongside virtual attendees joining the hybrid session.

The event, held on 21 May 2026, opened with remarks from IEM President Ir. Yau Chau Fong and CDL Sdn. Bhd. Technical Director Ir. Soo Thong Phor, who highlighted the importance of cross-disciplinary collaboration in advancing sustainable engineering practice and strengthening knowledge exchange across the industry.

Ahmad Abdelrazaq, Founder of Rise Global LLC, drawing on experience across major supertall projects including Burj Khalifa and Merdeka 118, reflected on how high-rise design has shifted. Structural ambition is no longer the main driver. Integration across disciplines, digital systems and construction processes now defines delivery, alongside rising expectations for performance and sustainability.

That shift is most visible in technologies moving into mainstream use. Ultra-high performance concrete, modular construction, building information modelling, 3D printing and digital integration are increasingly embedded in delivery workflows. They improve coordination, reduce material waste and tighten control over execution.

The seminar also featured talks from Ts. Nursyuhada Binti Che Husain of CDL Sdn. Bhd., who focused on the practical application and performance challenges of high strength concrete, Prof. Ir. Dr. Mo Kim Hung of Sunway University, who discussed emerging pathways in carbon utilisation, and Lee Mun Sam of Eastern Pretech Solutions Sdn. Bhd., who highlighted the role of precast systems in improving buildability and delivery efficiency for high-rise construction.

High strength and high-performance concrete remain central to tall building construction, but compressive strength alone no longer defines adequacy. Attention has shifted to in-situ behaviour during pumping, placement and curing, particularly under tighter programmes and more complex mix designs involving supplementary cementitious materials. Consistency and constructability now sit alongside strength.

Mineral carbonation is emerging within wider decarbonisation pathways, exploring how carbon dioxide can be converted into stable mineral forms for potential use in construction materials. Still in development, it reflects how material science is beginning to engage more directly with embodied carbon.

Precast systems are gaining traction in high-rise delivery where precision, speed and repeatability are critical. By shifting work off-site, precast reduces variability, improves quality control and streamlines installation sequencing, enabling more predictable project execution.

Taken together, these developments point to an industry moving beyond isolated innovation towards convergence across technology, materials and methods. As tall buildings continue to define urban skylines, the focus is shifting towards delivery models that are more efficient, lower in environmental impact and more tightly integrated across the value chain.

Through initiatives such as this seminar, CDL Academy and IEM continue to strengthen industry capabilities and create platforms for meaningful knowledge exchange that support the profession’s continued evolution.

This commitment will be further reinforced through the signing of a Memorandum of Understanding between CDL Academy and IEM on 15 June 2026 to advance engineering excellence, strengthen industry development and contribute towards the nation’s progress.
