This precast innovation was first introduced in the early 1900s. Today, some precast concrete is available in standard shapes and dimensions, such as floor and roof planks. Precast concrete may otherwise be fabricated in any shape and size consistent with the bylaws, the strength and stiffness of the materials, and the constraints imposed by formwork, transportation, handling, and erection.
Its ability to fit and mould into any form of design offers a lot of room for creativity and flexibility for designers and architects. And due to the inherent structural capabilities of precast, structures can also be designed for practically any soil or seismic condition. Precast concrete allows limitless customisation options and reduces the time taken for in-situ concrete construction and the safety factors involved in its assembly.

Important aspects in high-rise construction using precast technology
A representation of a high-rise building using precast concrete technology. From far it is nearly impossible to distinguish a precast building from a conventionally constructed one.The three most important aspects one should consider in the context of high-rise construction and evaluate the merits of precast technology are safety and structural stability of the building, timeline required for completing the project, and the costs involved.
Safety is of paramount importance in high-rise construction due to the complexities and challenges involved in erecting tall structures. High-rise buildings must be designed and constructed to withstand various forces such as wind, seismic activity, and the vertical loads imposed by the structure itself. Implementing appropriate safety measures, using high-quality materials, adhering to building codes and regulations, and conducting thorough inspections are crucial to ensure the safety of the building, workers, and occupants. Additionally, precast elements can be designed with built-in safety features, such as fire-resistant materials and seismic reinforcement, ensuring the structural integrity of the building during unforeseen events.
Numerous high-rise buildings worldwide have been successfully constructed using precast concrete elements. For example, the Aqua Tower in Chicago, USA (82 floors), Pearl River Tower - Guangzhou, China (71 floors), The Gramercy Residences - Makati, Philippines (73 floors), Bahrain World Trade Center - Manama, Bahrain (50 floors), Palais Royale - Mumbai (88 floors), Supernova Spira - Noida (80 floors), and The Park – Kolkata (27 floors).
