Objectives of Class
  • To introduce various types of project delivery
    methods.
  • To distinguish between the common project
    delivery methods.
  • To introduce different types of contract and to
    differentiate between the different contracting
    methods.

Project Delivery Methods What is it ?
  • The term delivery method means the approach
    used to organize the project team so as to manage
    the entire designing and building (design-build)
    process.
  • The owner needs to decide which designers to
    hire, when to hire them, and under what type of
    contract ?
  • The owner also needs to decide when to hire the
    construction professional and under what type of
    contract ?
  • Which organization gets hired first? Do both
    organizations report to the owner, or does one
    report to the other?
  • Project Delivery method is an organizational
    concept which assigns specific responsibilities
    and authorities to people and organizations and
    which defines relationship of the various
    elements in construction of a project.

Definitions Project Delivery systems
  • A project delivery system is the method by which
    a construction project is executed.
  • It is the first allocation of base
    responsibilities between the owner, design
    professional and contractor. Thus, the project
    delivery system is the foundation on which all
    subsequent negotiations will be based.

Types of PDM
  • Types of Project Delivery Methods
  • Traditional
  • Design- Build (Turnkey)
  • Professional Construction Management (PCM)
  • BOT ( Build Operate Transfer)

12
Traditional
  • The owner hires a design professional who
    prepares a complete set of contract documents for
    the owner for a design fee.
  • The owner either negotiates a price with a
    general contractor or bids out the work.
  • The general contractor is totally responsible for
    delivering the completed project as spelled out
    in the contract documents.
  • The general contractor may subcontract out parts
    of the project, with each subcontractor reporting
    directly to the general contractor.
  • The designer may be involved in overseeing the
    construction work in the field.
  • In this delivery method no direct, formal
    relationship exists between the designer and the
    builder. They communicate only through the owner

Advantages- Traditional PDM
  • Familiarity Most owners, designers, and builders
    have worked under this framework on many projects
    and therefore are familiar with the system.
  • Overall Job coordination Their control systems,
    documentation, and organizations are all set up
    to manage this process. The workers,
    subcontractors, and vendors also understand the
    system, improving overall job coordination.
  • Owner can get a firm fixed price for the project
    before any work begins. The owner knows before
    construction begins what the cost of the project
    will be.
  • Opportunity to get good price competition from
    the open market.

15
Pros and Cons of the Traditional Approach
16
Design-Build
  • In this approach, a single organization is
    responsible for performing both design and
    construction .
  • Within the design-build organization, parts of
    the design may be subcontracted to specialist
    consultants.
  • Being responsible for both design and
    construction, the design-build contractor carries
    most of the project risks, and this can mean
    additional cost to owner.
  • The owner's role in this approach is minimal and
    is only to express his or her objectives and
    specifications precisely before detailed design
    is started.
  • Historically, the design-build approach has been
    used on large, privately funded,
    industrial-sector projects. Recently, however,
    this approach has begun to be used on commercial
    building projects, some publicly funded.

Design-Build Advantages
  • Good communication occurs between the design team
    and the construction team. Allows for
    constructability analyses and value engineering.
  • This collaboration allows the project to be
    easily fast-tracked, cutting down on the
    design-build time for the project.
  • Good cost estimating and scheduling should occur
    throughout the entire project.
  • Long-lead item identification and ordering should
    also be able to proceed smoothly.
  • In general, this arrangement allows easier
    incorporation of changes due to changed scope or
    unforeseen conditions than in the other
    arrangements, since the coordination is to occur
    within the same company.

20
Pros and Cons of the Design-Build Approach
21
BOT (Build Operate Transfer)
  • The term Build-Operate-Transfer (BOT) was first
    coined by Ex-Prime Minister of Turkey, Turgut
    Ozal in 1984
  • Essentially in a BOT project delivery method, a
    private entity, usually a consortium is
    responsible for financing, construction,
    operation and maintenance of the facility for
    agreed duration known as Concession period and at
    the end of the period, transfers the ownership of
    the facility to the government.
  • A BOT mechanism is a complex structure comprising
    multiple, inter-dependent agreements among
    various participants.
  • The concession agreement is between the
    government and the concessionaire. The concession
    agreement is regarded as the heart of a BOT
    project

22
BOT (Build Operate Transfer)
23
BOT Advantages
  • The private firms are more efficient, hence
    project or service can be delivered at lower cost
  • The private sector invests directly in the
    development of infrastructure, thereby reducing
    public debt, balancing the budget deficit, and
    reduced role of public sector
  • BOT projects create business opportunities for
    the local private sector, create employment
    avenues as well as attract substantial foreign
    direct investment
  • BOT projects help in facilitating transfer of
    technology by introducing international
    contractors in the host countries

24
BOT Disadvantages
  • Transaction costs are high, they amount to 5-10
    of total project cost
  • Not suitable for smaller projects. Victorian
    Government of Australia has suggested that
    projects with a value of less than Australian
    dollar 15m are unlikely to gain benefits from
    BOT delivery method.
  • The success of BOT project depends upon
    successful raising of necessary finance.
  • BOT projects are successful only when substantial
    revenues are generated during the operation
    phase.

25
Professional Construction Management
  • In this approach, the owner appoints a PCM
    organization (also known as construction
    management organization) to manage and coordinate
    the design and construction phases of a project
    using a teamwork approach.
  • The design may be provided by specialist design
    firms and in some cases by the PCM organization.
  • With a high level of coordination between the
    participants, innovative approaches of
    overlapping design and construction (i.e., fast-
    tracking) can be adopted.
  • The PCM organization aims at holding a friendly
    position similar to that of the consultants in
    the traditional approach.
  • The services offered by the PCM organization
    overlap those traditionally performed by the
    architect, the engineer, and the contractor.

26
Professional Construction Management
  • This may include
  • management and programming of design
  • cost forecasting and financial arrangements
  • preparation of tender documents tender analysis
  • and selection of contractors
  • selection of methods of construction
  • planning and scheduling construction works
  • materials procurement and delivery expeition
  • Although this approach is likely to prove
    marginally more expensive than the traditional
    approach, it offers greater guarantee of
    performance and the potential to avoid time
    overruns and to reduce the cost of claims.
  • The payment to the PCM organization is usually a
    fixed fee or a percentage of the total project
    cost.
  • Use of PCM approach, should be considered when
    there is a need for time saving and flexibility
    for design changes, and the owner has
    insufficient management resources

PCM Advantages Disadvantages
29
  • Advantages over traditional A/E construction
    administration
  • CM with a construction background may be BETTER
    QUALIFIED
  • CM provides greater QUANTITY of construction
    phase services
  • CM often assumes greater DEGREE of control over
    contractors
  • limitations the professional or agent CM
  • DOES NOT guarantee construction cost or time
  • DOES NOT perform any work or contract with the
    trade contractors
  • IS NOT RESPONSIBLE for their performance
  • usually DOES NOT assume responsibility for safety
