While recognized globally for their aesthetics, the construction of the Petronas Twin Towers was about more than just beauty it represented an advancement in construction. Each tower was constructed using high-speed construction that resulted in an average of only 4.5 days of construction time per floor, with construction of all 98 floors completed in 28 months. To achieve this rapid construction pace two new technologies were utilized: high-pressure concrete pumping to a height of 381 meters, 800kg/cm2 high-strength concrete.

A team led by Samsung was awarded the contract to construct Tower Two. The construction of the superstructure commenced in April 1994, after rigorous tests simulations of wind structural loads on the design. To address environmental concerns, including wind, a composite structure was utilized, capturing the advantages inherent in steel (flexibility) high-strength concrete (rigidity). Each material was used to capture maximize its best effect in constructing the 452 meter-high buildings. About 80,000 cubic meters of high strength concrete with 37,000 tons of steel were used to form the frame of Tower Two.

Of particular importance was maintaining the verticality of the structures throughout construction to ensure structural load integrity the safe operation of the high-speed elevators once the buildings were opened. To achieve proper construction, surveyors monitored construction daily using global positioning systems (GPS) to check alignment on a daily basis.

Construction works were done primarily at night finishing works were done primarily during the day (to minimize the cost of artificial lighting). As a result, the entire management construction team redefined the Malaysian industry stard of fast-track.

External finishing work, primarily steel glass, was completed in June 1996. Internal finishes, many of which were locally sourced, were completed at the end of 1996.
