Title: Construction Engineering CCE 4004


1
Construction EngineeringCCE 4004
  • Lecture 2
  • Construction Industry Project Development
  • Project Delivery Systems

2
Lecture Outline
  • Construction Industry
  • Statistics
  • Characteristics
  • Facility Delivery Process.
  • Facility Delivery Systems.

3
Statistics
  • 8 - 12 GNP
  • 900 Billion dollars of activity per year
  • Approximately 1 million contractors
  • Less than 50 of annual volume performed by top
    400 contractors
  • Over 70 contractor associations
  • Over 10,000 local and national labor
    organization.
  • Approximately 6.0 million workers

4
Statistics (Contd)
  • Research and development (RD) 0.4 of annual
    sales (automative gt 3 of annual sales and drug
    companies gt5)
  • Total replacement cost of built environment
    (public and private) gt 21 trillion dollars 1992
    dollars

5
Characteristics
  • Long history - Attachment 1
  • Protect - drive - Attachment 2, 3, and 4
  • Fragmented - types of construction.
  • Residential (50)
  • housing and apartments
  • Commercial Institutional (25)
  • building ( office space, institutional)
  • Infrastructure (20)
  • telephone, railroads, civil projects (dams,
    tunnels, airports, wastewater, water, highways,
    bridges )

6
Characteristics (Contd)
  • Industrial (5)
  • manufacturing ( steel, auto, consumer products )
  • power ( coal, nuclear, fossil )
  • process (plastics, paper, pharmaceutical )
  • Transient nature
  • Dynamic/continually changing
  • Non-repetitive
  • Lack of data
  • Lack of standardization

7
Characteristics (Contd)
  • Low tech
  • Large number of participants ( Attachment 5 )
  • Legal and regulatory requirements

8
Facility Delivery Process
  • Process in which ideas are transformed into
    useful facilities
  • Every construction project is completed with a
    Facility Delivery Process
  • Facility delivery process structure
  • Planning
  • Design
  • Construction
  • Startup and Commissioning
  • Operation and Maintenance

Facility Delivery Process (cont'd)
  • Planning
  • owner expresses a need for a new facility
  • concepts are worked out
  • feasibility studies are a must

12
Facility Delivery Process (cont'd)
  • Design
  • Where the majority of engineering takes place
  • Detailed plans and specifications are developed
  • Owners initial ideas are further refined
  • Owner gives go-ahead
  • Contract is bid and awarded

13
All we do is put it on paper. Its your job to
build it.
14
  • There Comes A Time in The History Of Every
    Project When It Becomes Necessary to Shoot the
    Engineers and Begin Production

15
Facility Delivery Process (cont'd)
  • Construction
  • Where the physical manifestation of the design
    appears
  • Design often continues through construction
  • Startup and Commissioning
  • Verifying whether the constructed facility
    operates as designed

16
Facility Delivery Process (cont'd)
  • Operation and Maintenance
  • Owner accepts built facility
  • Facility continues in OM until it is renovated
    or decommissioned

17
Methods of Delivery
  • Selecting a project delivery system depends on
  • Complexity of the project
  • Owner's resources and risk management
  • Past experience
  • Corporate policy
  • Value of time
  • Value of innovation
  • Owner assumes risk in selecting a project
    delivery system losses occur if need is not met.

18
Traditional Delivery System
  • Design-bid-build
  • Also known as hard money or competitive bid
    contracts
  • Has three sequential phases
  • Design AE hired to develop design
  • Bid/Award usually competitively bid by several
    contractors then awarded to lowest responsive
    bidder or most qualified bidder
  • Construction begins after design and bidding are
    complete

19
Traditional Delivery System
  • Organizational chart for traditional delivery
    system

20
Design-Build Delivery System
  • Single company is responsible for both design and
    construction

21
Design-Build Delivery System
  • Forms of design-build organizations

22
Agency Construction Management
  • Owner hires construction manager separately from
    A/E and general contractor
  • Owner assumes greatest risk

23
Construction-Manager-at-Risk
  • Owner contracts with designer and construction
    manager separately
  • Construction manager assumes greatest risk

24
Other Delivery Systems
  • Owner design-builder
  • Owner has own in-house designers and in-house
    builders

25
Other Delivery Systems
  • Owner construction manager
  • Owner contracts with a designer but uses own
    in-house construction manager

26
Practical Recommendations
  • A successful project does not just happen!
  • There are numerous factors, general and
    project-specific, that can influence the outcome
    of a project
  • Project-dependent factors certain types of
    projects have different signs of success.

27
Summary
  • Construction industry is
  • LARGE
  • DIVERSE
  • UNIQE
  • COMPLEX players, defined roles and
    responsibilities, timing of participation,
    practice-sports, arts
  • Construction is important to the economy as it
    affects costs, prices, and our international
    competitiveness.
  • We need to separate the forest from the trees,
    i.e., take a holistic view of the facility
    delivery process.

28
Summary (cont'd)
  • Owner always takes a risk in selecting a project
    delivery system
  • A key issue is total time from concept to
    completion, dependent on the owner's needs
  • Each project delivery system can be used with
    several different commercial terms
