2Lecture Outline
- Construction Industry
- Statistics
- Characteristics
- Facility Delivery Process.
- Facility Delivery Systems.
3Statistics
- 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
4Statistics (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
5Characteristics
- 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 )
6Characteristics (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
7Characteristics (Contd)
- Low tech
- Large number of participants ( Attachment 5 )
- Legal and regulatory requirements
8Facility 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

11Facility Delivery Process (cont'd)
- Planning
- owner expresses a need for a new facility
- concepts are worked out
- feasibility studies are a must
12Facility 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
13All 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
15Facility 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
16Facility Delivery Process (cont'd)
- Operation and Maintenance
- Owner accepts built facility
- Facility continues in OM until it is renovated
or decommissioned
17Methods 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.
18Traditional 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
19Traditional Delivery System
- Organizational chart for traditional delivery
system
20Design-Build Delivery System
- Single company is responsible for both design and
construction
21Design-Build Delivery System
- Forms of design-build organizations
22Agency Construction Management
- Owner hires construction manager separately from
A/E and general contractor - Owner assumes greatest risk
23Construction-Manager-at-Risk
- Owner contracts with designer and construction
manager separately - Construction manager assumes greatest risk
24Other Delivery Systems
- Owner design-builder
- Owner has own in-house designers and in-house
builders
25Other Delivery Systems
- Owner construction manager
- Owner contracts with a designer but uses own
in-house construction manager
26Practical 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.
27Summary
- 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.
28Summary (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
