    CHAPTER I

    INTRODUCTIONS

    Preface:

    Over the past several years, the construction industry has seen enormous changes. From an

    industry steeped in conservative practices and narrowly scoped services, construction has moved

    to the forefront of the design and construction profession. From general contracting to

    construction management to project management and program management, the method of

    servicing the industry has evolved to be more varied and comprehensive. This requires students

    alike understand the many aspects of the world of owners, designers, tenants, regulatory agencies,

    community agencies and subcontractor. Each participant brings political, professional and

    personal motivation to the process, and each has the ability to place constraints on the project. To

    effectively navigate in this environment, the successful project manager must recognie the role

    of each participant, understand the nature of the project itself, and effectively use management

    tools to bring the project forward in a timely and cost effective manner.

    !n this project, we have decided to choose "uala #umpur $ity $enter %"#$$& as our

    group scope of study. This project will e'plore the people involved in the design and construction

    process, the principal phases of a project, the bidding and procurement process and the tools

    required to effectively manage the people and the project.

    Objectives:

    Objectives of this project are(

    i. to e'plore the people involved in the design and construction of "#$$

    ii. to e'plore the principal phases during "#$$ construction

    iii. to know the bidding and procurement process related to "#$$

    iv. to evaluate the tools required to effectively manage the people and the project.

    BACKGROUND OF KLCC

    Itr!"#cti!s:

    The )etronas Twin Towers were designed to be the centrepiece of a larger comple' called

    the "uala #umpur $ity $entre %"#$$&, a mi'ed*use development with a site area of +.+- acres,

    which includes the towers, two other office towers, underground parking and service facilities.

    The project site is well located in the heart of the commercial district of the city, the /olden

    Triangle0. Each of the twin towers is eighty*eight storeys high and contains 1+2,333 square

    metres of floor space. 4ising -1 metres, the towers were certified the world0s tallest buildings by

    the $ouncil of Tall 5uildings and 6rban 7abitat in +889. The two towers are connected by a sky

    bridge at the forty*first and forty*second floors : the sky lobby levels : to facilitate inter*tower

    communication and traffic. ; multi*storey shopping and entertainment galleria connects the office

    towers at their bases, integrating the entire comple'. Other public functions within the comple'

    include the )etroleum

    Tower and thirty*story Esso Tower together will provide +.B million sq. ft. of office space, while

    a+.- million sq. ft. shopping center will bring retail activity to much of the ground area of the

    development.; + million sq. ft. hotel will occupy another thirty*eight*story tower in the Corth

    Dest ymphony 7all will occupy a space immediately beneath the

    towers. ;n 23,333 sq. ft. mosque,a utility plant that will service the entire district, and more than

    fifty acres of park space are also includedin this first phase of construction.

    !n >eptember +881, the site for the )etronas Towers was moved 133 ft. to the southwest

    after the resultsof more thorough geotechnical studies were known. The e'istence of a

    subterranean porous limestonecliff, which dropped in elevation from near the surface to a depth of

    more than B8- ft. over the span of thesite, made the location of piles e'tremely difficult in the

    original location.

    PRO(ECT PARTICIPANTS

    Itr!"#cti!:

    The people in construction cover a wide range of skills and e'perience. From apprentice

    carpenters to company e'ecutives, the one thing that they share is their passion for the built

    environment. The building industry is a tough one( risks are high, working conditions are often

    harsh, conflicts arise because of financial pressures, and safety is always concern. !nteractions

    among the people on the job can determine whether the project succeeds or fails. Thus, it is

    important to understand who these people are and what their motivations will be when they come

    to job.

    The industry is changing. Co longer are the roles of individuals distinct and understood by

    all participants. 5ecause of the sophistication of some modern projects, owners desire to minimie

    risk, and the professionaliation of the construction industry, these roles are shifting and merging.

    Owners can have large in*house design and construction groups.

    CHAPTER I+

    PRO(ECT GRO,TH

    Itr!"#cti!:

    The life of a facility goes through many phases. !t starts out as an idea. The idea is

    combined with money, and a project is born. The project is developed as drawings and

    specifications. !t is then built. Dhen it is complete, it is turned over to the owner as a finished

    facility and is occupied, maintained and repaired as it ages and eventually dies. ; facility can last

    for hundreds of years, but the period in which it is actually designed and built is very small.

    =any people are involved in the life cycle of a building. First are those who analye the

    need for the facility and decide whether it is economically and programmatically feasible. Then

    the project enters the designbuild phase. ;rchitects are hired to design it. $onstruction

    professionals are hired to carry out the actual assembly and erection process. ;ll parties, no

    matter what the contractual arrangement, need to work in harmony to fulfill the many functions

    that must be performed.

    Iitiati! P$ase:

    !nitiation phase is the first stage for most projects. =ost attention and effort during a

    project is focused on the end point or final delivery. !f projects were managed more carefully

    during the initiation stage, we might have fewer problems in the final stage. "#cc construction

    management as we knew had a big collaboration of internationals agencies,constractors and also

    consultants. To answer this initiation phase, we will look what the objectives behind the decision

    taken before because it answer our questions why government awarded this project to

    international company

    10

  • 8/13/2019 Cm Full Report Print

    11/32

    For "#$$, what had been done at initiation phase was to decide to whom should the

    tender be awarded to. 5ased on the Dawasan 1313 at the beginning , government tried so hard to

    push forward local contractors and also building industry members. Thus, one of the objectives in

    the construction of "#$$ were to create an engineering decision that will challenge local

    industries.

    Otherwise, they also meant to develop local industries to permeated all levels of the

    international design and construction process. ;long with this initiation phase, it been decided

    that they wanted a combination of local and international firms in bidding.

    Furthermore, they want to create innovative engineering and construction strategies like a

    proposal to built a skybridge that connected 1th and +stfloor from each tower. Other e'ample

    regarding this was a decision to frame a buiding of this scale using a high*strength concrete that

    had never been implemented at any construction in =alaysia. This is due to success of $hicago

    Tower implemented the same type of concrete.

    5ecause of their decision to use high strength concrete, they want to create a technology

    that can be use to pump up the mi' to this height which led to testing of two different concrete

    delivery system.

    #ast but not least was the irregular condition of the soils demanded the use of detailed

    geotechnical studies to carefully sie and position each aspect.

    Feasibi&it- St#"-:

    Feasibility study is an advance assessment towards a project to make a rational decision

    whether the project should proceed or not.!t consists of - major aspects(

    i. Technical

    * The best two contractor from korean and japan were need to present

    their technical capacities include labour and technologies aspect.

    * !n pumping up the concrete,each of them had presented the best

    technology they can provide for this construction.The "orean team had

    use the powerful /erman*enngineered pums,breaks the world record

    for the highest continuous pump. On the other hand, Aapanese team had

    use the imported technology of the high*speed hamper hoise from 6>;

    to lift concrete to an intermediate pumping platform.

    * ;ccording to their decision of using the high strength concrete,it is a

    problem to find a supplier that can provide on*site batching plant.

    Fortunately, after carefully searching, a supplier from ;ustralia was

    chosen to provide on*site batching plant. ; backup plan had been use

    that was support from local production of the structural concrete helped

    avoiding any delays.

    * These aspects of technical preparation made the team confident to

    proceed this project

    ii. Financing

    * total cost of "#$$ construction at that time was +.2 billion. 4egarding

    where to money came from is a bit too private and confidential for

    public e'pose. 5ut, at that time, =alaysia economic growth had reach

    at its peak time when we also in a line to increase outside

    investors,thus,their contribution through money spending also make our

    country able to provide a proper financing for "#$$

    iii. Economical

    * it is related what is the return after the completion.

    * at that time,a research found that it can attract multinational companies

    to allocate their office in both towers since "#$$ itself located at a

    very strategic location.

    * not just that,feasibility studies also shown that it can increase

    international investors on shopping center located at the base of the

    tower.Furthermore, it can also attract tourists from all over the world

    and at the same time increase the our tourism industry.

    The glass that was used, which had a slight green tint because of its low*E coating,

    allowed the tower to become quite transparent. This transparency allowed the human scale to be

    perceived from outside the building.

    >tainless steel louvers that projected past the surface of the building were carefully

    engineered to shade the window surfaces while ma'imiing views from the interior.The e'istence

    of the e'ternal louvers has also reportedly improved the psychological character of the interior

    spaces by offering a level of reassurance to inhabitants.

    The eighty*eight story towers, connected by the skybridge at levels forty*one and forty*

    two, define a space that )elli describes as a portal that ?symbolies the threshold between the

    tangible and the spiritual worlds.

    The use of stainless steel as a cladding material was also unique for a project of this scale.

    The towers, which )elli refers to as ?cosmic pillars@ and )ickard has called ?columns of light,@

    owe much of their lightness to the integrated use of clear glass and stainless steel in the cladding

    system.

    Throughout the initial design phases, members of the "#$$ architectural division rotated

    into the Cew 7aven office of $esar )elli and ;ssociates, some staying for as long as a year.

    The contract was awarded on =arch +88B. The foundation contracting

    team consists of

  • 8/13/2019 Cm Full Report Print

    18/32

    teams are referred as Team Aapan and Team "orea. Throughout the

    construction of the towers, members from each team were permitted to

    enter the construction site of the other team only during scheduled tour,

    which took place every Dednesday. This tours are well attended and

    tremendous amount of information was e'changed during these encounters.

    The e'tensive construction supervision provided by the engineers,

    architect, and management teams was also an acknowledge conduit for

    information transfer between the towers.

    Each tower is supported by a ring of si'teen cylindrical columns of high*

    strength reinforced concrete, placed on the inner corners of the star*shaped

    plan to form a soft*tube0, with the columns linked by slightly arched ring

    beams, also made by structural concrete. The columns are nearly 1. meters

    in diameter at the base of the building, but the taper as they rise through the

    floors, as well as sloping towards the center of the towers, enhancing the

    building0s svelte profile. ;t the centre of each tower is an appro'imately

    1B*by*1B*metre concrete core. $oncrete outrigger beams tie the perimeter

    columns to the cores at the thirty*eighth and fortieth levels, to provide

    additional stiffness to the structure. The core and cylindrical tube frame

    system is constructed entirely of in*situ high*strength concrete, as aretwelve smaller perimeter columns and ring beams around each bustle0.

    The cores create two virtually ?solid@ walls running north*south and east*

    west. >tructural steel was used for typical long span floor beams supporting

    concrete*filled metal deck slabs, and each of the curved or pointed bays

    cantilevering beyond the perimeter columns is steel*framed.

    * =echanical >ystems

    The mechanical systems incorporated in the )etronas Towers are

    unprecedented in =alaysia. ;n advanced P*cool recovery0 system is used

    to save energy. ;dvanced fiber*optic networks are in place to facilitate data

    transmission. ; carefully organied elevator system was needed given the

    height of the towers.

    ; unique fire control system was also developed to respond to the specific

    needs of such a tall building and the limitations of the "uala #umpur

    infrastructure.

    The consistent heat and humidity of this tropical city necessitated an

    innovative cooling system for the )etronas Towers. To maintain a high

    level of air quality within the project, the consulting mechanical

    engineering firm of Flack and "urt stressed the importance of a high

    turnover rate of fresh air. The e'ceedingly warm climate of "uala #umpur

    made this an e'pensive proposition. To minimie the cost of cooling the

    inflow air, Flack and "urt incorporated energy recovery wheels into the

    air handling system. Corman "urt, a principal of Flack and "urt, noted

    that although this technology had been available for almost twenty years,

    ?its application in an office building near the equator is unique.@+- The +1*

    ft.*diameter wheels rotate slowly as the supply and e'haust air streams pass

    over them. The heat from the incoming e'terior air is transmitted through

    the wheel into the cooler e'haust air. >imultaneously, a dessicant in the

    wheel absorbs humidity from the inflow air and discharges it into the

    e'haust air to help minimie the load on the building0s dehumidification

    equipment. This system reportedly drops the humidity of the supply airfrom 83 percent to H3 percent and reduces the fresh air cooling load by as

    much as -3 percent.

    The fire control system needed to be developed in accordance with the

    highly specific demands placed upon it by the height of the towers and the

    congestion of downtown "uala #umpur. The inability of fire apparatus to

    navigate the traffic of the city center made it essential that any fire in the

    comple' could be controlled locally. To meet this demand, e'tensive

    sprinkler, pressuriation, and smoke e'haust systems have been integrated

    into the building.

    19

    20/32

    5ecause of the difficulty of egress in towers of this scale, it was important

    to incorporate pressuried safe ones throughout the comple'. !n the wake

    of the Oklahoma $ity terrorist bombing, a number of changes were made to

    the buildings security and safety systems that were already under

    construction. Emergency generators, located on the premises of the towers,

    were relocated away from the building. ;ll parking was removed from

    beneath the towers and more backup fire controls were added. The

    skybridge came to be seen as a key path for emergency egress between the

    towers.

    * $ladding

    The fabrication of the e'terior cladding system was carried out locally by a

    limited partnership organied by 7armon, a curtain wall fabricator from

    =innesota. The large*scale investment in machinery and personnel that

    7armon had already committed to projects in =alaysia made the company

    a clear choice for the curtain wall contracts. This commitment aligned with

    the secondary goals of information transfer, and a number of facilities

    organied and constructed for the )etronas project have continued

    production following the completion of the towers.

    The locally manufactured stainless steel curtain wall system consisted oflarge low*E coated glass panels held in a stainless steel frame. >tainless

    steel louvers projected out from the surface of the panels to help eliminate

    solar gain from high sun angles. The panels were designed and produced to

    navigate three slope changes that occur because of the stepping back of the

    tower profiles. !nter*story drift, calculated to be as much as . inches per

    floor, had to be accommodated by the panel connections. 5efore the

    production of the B+,333 panels to be used in the towers, three full*scale

    9-.9*ft.*square panels were tested e'tensively at $onstruction 4esearch

    Fabrication

    The skybridge was fabricated and shop assembled by >amsung

    7eavy !ndustries of >outh "orea. The fabrication works complied

    with some of the most stringent industry standards and codes such

    as those maintained by the ;merican >ociety for Testing and

    =aterials %;>T=&, 5ritish >tandard %5>&, and ;merican !nstitute

    of >teel $onstruction %;!>$&. The fully assembled bridge was then

    dismantled and shipped to "uala #umpur in 8B pieces %-1.9

    tonnes&. To facilitate putting it into place, the skybridge was pre*

    assembled into five main components comprising the two legs, two

    end blocks and the centre section.

    $entre >ection

    The B3H parts of the frame for the centre section of the skybridge

    were fully assembled and bolted. The centre section of the

    skybridge frame, measuring + metres in length, over - metres in

    width and nine metres in height, was assembled at the concourse

    level. The centre sectionKs internal floors and roof at level +, 1

    and B were constructed in metal decking. ;fter the roof level

    concrete slab was placed, the whole assembly was painted and the

    e'ternal building maintenance equipment for the legs installed. >kybridge #egs

    The two inclined legs are appro'imately 1.9 metres long and

    weigh about 93 tonnes each The five sections of each set of legs

    were completely assembled and checks on the whole dimension,

    camber and alignment were made before bolting.

    Tuned mass dampers have been engineered for the legs. These

    dampers have been designed after a complete wind tunnel test to

    accommodate the comfort level by dampening any effects of

    unusual wind conditions and possible long term fatigue due to

    resonance of the legs. This pendulum operated dampers were field

    tested and inserted to the centre section of the legs just prior to final

    assembly.

    End 5locks

    5oth end blocks of the skybridge were assembled at concourse level

    with main girders, cross beams and horiontal bracing. The two end

    blocks are appro'imately 2.B metres long and weigh about B3

    tonnes each. ;fter the whole dimension and alignment of the end

    blocks were checked, they were ready to be lifted.

    #ifting of >kybridge

    I># 7eavy #ifting, a specialist in this field, was appointed for the

    lifting of the skybridge studies and preparation for the lifting was

    carried out for more than a year in several countries including the

    6nited >tates and >outh "orea, simulating various wind and

    weather conditions including those based on actual load data over

    the past -3 years. There are nine main steps in the lifting of the

    skybridge.

    * )innacle

    The two +-3*ton stainless steel pinnacles were fabricated off*site and

    installed upon completion of the structural frame of each tower. The

    installation was a clear e'ample of the competition between the teams as

    well as the opportunity for information transfer.%Fig. +-& ;lan Caspinskicompared the installation techniques employed by the two teams when he

    said, ?De were concerned that having the mesh ball attached to the

    pinnacle as it was hoisted would complicate the installation. Therefore, we

    chose to install the ball after the pinnacle had been set in place. The "orean

    * Elevator

    !n office buildings the sie of the )etronas Towers, it is important that there

    be an efficient elevator system that can handle the large numbers of people

    that use the elevators simultaneously.

    >ince the towers are each 22 stories high, it is inefficient in terms of

    money, space, and time to have single elevators traveling directly from the

    bottom to the top of the building. This prompted the builders to design

    high*speed double*deck elevators.

    The organiation of double*deck system involves two elevators occupying

    one elevator shaft, but servicing different floors. The bottom elevator

    travels from the ground floor to the sky lobby on the forty first floor, while

    the top shuttle services floors 1 through 22. To further increase

    effectiveness, the elevators each carry 19 people and are designated to

    service only even or odd numbered floors. Dith each tower boasting 18

    double*deck elevators moving at speeds between B.- and H meters per

    second, there are shorter waiting times and less traffic.

    Dhen building these shuttles, the designers were concerned with speed

    along with the effects that such elevators have on passengers. >tudies have

    shown that during long descents, high*speed elevators can cause earaches,and, therefore, the elevatorsK speed should not e'ceed 1333 feet per minute.

    ; smaller circular bustle0 or anne', rising forty*four storeys, was added to each of the towers in

    order to provide more usable space. The towers are connected at the forty*first and forty*second

    levels storeys by a sky bridge to facilitate communication and traffic between the towers.

    Organied around this interchange are shared facilities such as the surau %prayer room&, the

    ;lthough the appointment of the architectural team, prior to the arrival of #ehrer=c/overn, had

    involved a relatively informal negotiating process, the competitive bidding for the big*

    ticketcontracts was a highly formal and controlled undertaking.

    Every bidding company was asked to submit two entirely separate and highly detailed bid

    packages. Thefirst package, called the ?technical proposal,@ was used to determine the capability

    of the company tocomplete the work satisfactorily. ; highly organied process set out the

    guidelines for this technicalreview. ;fter signing in, the members of the review board were given

    the equipment they would need toanalye the technical proposal. The technical review board then

    submitted a technical review booklet tothe steering committee with its recommendations. ;ny

    firms that were judged incapable of the work werethen omitted from the second stage of the

    bidding process.

    To determine this, about ten questions wereasked, including(

    ;ccording to 5ruce >chlaiter, the project manager from #ehrer =c/overn,the makeup of the

    international teams and the care with which local contractors were integrated into thegroup was an

    important factor in the final decision. Of the nine international teams that submitted bids,two were

    eliminated after the review of the technical proposals. The evaluation of the commercial

    bidsrevealed that there were only nominal benefits from contracting the entire project to one team.

    Theproject management team decided that they didn0t want one really large contracting group

    setting thepace and quality level for a project of this scale. !n addition, concerns about the depth

    of financialresources that the project would require supported their decision to split the contract.

    The Tower Onecontract was awarded to a team that included 7aama $orporation and =itsubishi

    $orporation fromAapan, A.;. Aones $onstruction $ompany, !nc. from $harlotte, Corth $arolina,

    and the local =alaysian ==$ Engineering and $onstruction $ompany. This would come to be

    known as the Aapanese team.

    and Thornton*Tomasetti. !n most cases,some alterations were made as a result of these

    inspections to assure that e'pectations could be met.

    #ehrer =c/overn0s e'perience from the $anary Dharf project as well as their assessment

    of thecongestion of local roadswhich only appeared to be worsening as the project progressedled

    them torealie that it would be necessary to produce the required concrete on*site. The grade 23

    high*strengthconcrete specified for much of the buildings0 structural system had never been

    produced in =alaysia. !twas therefore important that the engineers and project management teams

    be able to maintain a highlevel of quality control. "#$$ and #ehrer =c/overn put the concrete

    was chosen. !nstead of a contract alicensing agreement was drawn up. #ehrer =c/overn set up an

    agreement that the contractors coulduse any supplier of concrete as long as they could

    demonstrate cost savings e'ceeding - percent by notusing the on*site facility. 5oth teams were

    supplied by )ioneer.
