  • KLCC PETRONAS TWIN TOWER WONG CHOONG LING @AUDREY 0314504 WONG HA SHIONG 0309640 YAP ZHI XIN 0314542
  • CONTENTS • Background Information • Type of structure and main materials used • Industrialized building systems (IBS) implemented during the construction of the towers • Discuss on how IBS helped the construction of those buildings/ structures • Q&A
  • BACKGROUND INFOMATION • Tallest buildings in the world (1998 – 2004) • Designed by Argentine American architect, César Pelli, along with Deejay Cerico, J.C. Guinto and Dominic Saibo • 88 levels with the height of 452m • Cost about US$1.6 billion • Aim: • Built up the confidence in every Malaysian • Represents Malaysia’s increasing wealth and the nation’s desire to feature more prominently on the international stage
  • • As an internationally recognized landmark, the PETRONAS Twin Towers symbolize the courage, ingenuity, initiative, and determination, energy, confidence, optimism, advancement and zest of a nation." Stated by Tun Dr. Mahathir Mohamad, Former Prime Minister of Malaysia (1981-2003).
  • TYPE OF STRUCTURE AND MAIN MATERIALS USED • Consists of a 4.5m thick piled raft which called barrettes. • 23x23m concrete core located in the centre of tower with outrigger beams ties the perimeter columns to the cores
  • CONCRETE Grade M80 Most Cost Effective High Strength Concrete Central Core Perimeter Columns Perimeter Ring Beams Outrigger Beams Permitting Vertical Core Column Elements  Relatively light  Simple connections in joints  Reduces the building response to wind Stabilize STEEL Typical Longspan Floor Beams  Supporting concrete-filled metal deck slabs Tower & Base Innovative Light Weight Steel Framing System Clad with stainless steel extrusions  Non-crane erection methods  Provide required fire ratings
  • • The towers & base are clad with stainless steel extrusions • Custom made 20.38mm laminated light-green glass. • The curtain wall of each of the triangular corners is flat 90° corner & semicircular protrusions is faceted • Vision glass below a stainless steel sandrel with a grey glass sprandel on top raises one floor & spans.
  • • Sunscreen brackets provide shading which give the appearance of a continuous silver ribbon around • The sunscreen is made of cast aluminum end caps, fixed on brackets & finished with oven-cured PVF2 fluorocarbon paint • Finishes material used: • Local wood, • Terengganu granite • Marble
  • IBS IMPLEMENTED DURING THE CONSTRUCTION OF THE TOWERS • A process by which the parts of buiding are conceived, planned and fabricated, then transported and erected at the site - Junid (1986) • Was used in the construction of the Petronas Twin Tower as it saves times • Steel beams of the floor are made in steel plants in Malaysia and then installed into each of the floors • Used steel frame as it is easy to fabricate and install
  • • IBS also Implemented the IBS is the skybridge • The bridge was disassembled into 493 pieces and shipped to Malaysia • The bridge was pre-assembled into 5 components • The pinnacles on top of the building, which included a spire ball, the mast and a ring ball, were also done by the same way
  • DISCUSS ON HOW IBS HELPED THE CONSTRUCTION OF THOSE BUILDINGS • It provides high quality products as the parts can are fabricated in a factory • It also allows the product to be controlled easily and to high degree of precision • Quality of the components can be maintained at a consistent level • The final product of IBS will be at high quality
  • • It saves time and costs • Components fabricated off-site, less on site workers are needed which reduces labor cost • Time is saved as preparations are done in advance and putting the pieces into place is simple • Weather will not be an issue during casting as the components are casted in controlled environment in the factory • The construction will also be clean and neat with the less used of timber, nails and steel
