The planning of PETRONAS Twin Towers started in January 1992, led by architect Cesar Pelli along with engineer Deejay Cerico, designer Dominic Saibo and consultant J.C. Guinto.

Excavators began digging down 30 metres below the surface of the site on March 1993. The work required moving over 500 truckloads of earth every night. The next stage was the single largest and longest concrete pour in Malaysian history. 13,200 cubic metres of concrete was continuously poured through a period of 54 hours for each tower. This recordbreaking slab with 104 piles forms the foundation for each tower.

From this floor rose a 21 metre high retaining wall, with a perimetre length of over one kilometre. This concrete shell and the basement area it encloses required two years and up to 40 workers on site, all day and night.

The construction of the superstructure commenced in April 1994, after rigorous tests and simulations of wind and structural loads on the design.

The PETRONAS Twin Towers was finally encased in steel and glass and completed in June 1996. Tun Dr. Mahathir Mohamad officially opened the twin building on 31st August 1999.

Pinnacles

These structures house the aircraft warning lights and external maintenance building equipment.

Each pinnacle features a spire with 23 segments, and a ring ball comprised of 14 rings of varying diametre.

Exterior

Each Tower is set back five times in its ascent to maintain the vertical axis and tapering of the design. The walls of the uppermost floors are also sloped inward to taper and meet the pinnacle

The Towers feature multi-faceted walls of 33,000 stainless steel and 55,000 glass panels. Vision Glass, specialised panels with light filtering and noise reduction properties, provide a comfortable inner environment. The glass is covered with stainless steel visors to protect visitors from the tropical sun.

Interior

Designs and patterns of the entrance halls’ foyer reflect traditional handicrafts and ‘songket’, or weaving. In addition, hardwood carvings from the East Coast of Peninsular Malaysia inspire the motifs of wall panels and screens. The floor designs are based on intricate patterns of pandan weaving and bertam palm wall matting.

Lifts

The Towers house 29 double-decker high-speed passenger lifts, six heavyduty service lifts and four executive lifts.

The floors are based on a zoning arrangement: two sets of 6 doubledecker lifts serve levels 1 to 23 and levels 1 to 37, while another set of the five double-decker lifts take passengers directly to the Sky Lobby. Here, passengers take another lift to the upper zones.

The executive lifts are the longest rise in any office building in Malaysia. It serves every floor from the basement car park to the top of the Towers in 90 seconds.

Each passenger deck can carry 26 people or 52 in total, while the executive lifts can carry an average of 10. Its speed is between 3.5 metres per second (m/s) and 6.0 m/s, depending on the zones they are servicing.
