Segments
General Contractors
Residential, commercial construction.
Constrained by government and infrastructure requirements.
Heavy & Civil Contractors
Roads, bridges, etc. Infrastructure components.
Constrained by government resources and bureaucracy in addition to general contractor constraints.
Specialty trade contractors
Plumping, HVAC, painting, electrical.
Constrained by determined building designed.
ETSC 101 Chapter 6 Hacker
Segments are separated by the types of projects dealt with and the constraints associated. Different contractors are forced to work under different constraints.

What is Infrastructure?
Basic framework of structures essential for people to go about daily lives and comfortably conduct their affairs.
Examples:

Infrastructure
Not Infrastructure
Kind of Infrastructure
Component of Infrastructure
Cheats:
Civil and Heavy segments of construction are usually infrastructure components.
General contractor segments are usually for profit buildings.
Specialty contractor segments are usually types of systems in a building, not a building itself.
Impacts of Construction Technology
Social
New entrants to a community; different cultural backgrounds.
Relocations
Can change region from rural to suburban
Economic
New jobs and money
Increase in home price, decrease in home availability
Environmental
Soil erosion, ecology damage, use of land
Water and air pollution, noise, space and traffic pollution

Construction and Energy
Problem:
Make up around 40% of nation’s overall energy use.
Cause around 39% of U.S. carbon emissions (textbook says 43%)
Solution:
Zero-Energy Housing/Sustainable Construction
Use of alternative energies
Solar/ use of recycled products
Advanced insulation materials
Consolidated building components (Plumbing and HVAC)
Utilization of geothermal energy
ETSC 101 Chapter 6 Hacker
Activity: Determine the Impacts of the Construction and Presence of CWU
Consider social, environmental, and economic impacts
Consider energy usage and how sustainable construction was utilized.

Types of Structures
Residential
Commercial
Institutional
Industrial
ETSC 101 Chapter 6 Hacker
Significant Structures:
Industrial Plants
Roadways
Bridges
Tunnels
Sewers/Pipelines
Airports
Substructures and Superstructures
Substructures:
Unseen portions of the structure; the foundation
Spread footing
Spot footing
Piles
Superstructures:
Seen portions of the structure; the actual building
Mass
Bearing Wall
Framed
ETSC 101 Chapter 6 Hacker
Spread footing is used on hard surfaces and is placed along perimeter of the structure
Spot is used for pier or post placement
Piles are used where soil is soft or where the water table is high.
Mass superstructure is a solid erection of material with no space within the structure
Bearing wall is a wall of material forming perimeter to enclose a space
Frame super structure uses frames to support the structure.
9
Framed Superstructures
Framed superstructures need to be enclosed to seal the inside of a building from the outside.
Functions of Enclosures:
Support
Control
Finish
Distribution
ETSC 101 Chapter 6 Hacker
Support: Additional support for the building.
Control: Manage what gets in and what gets out.
Finish: Appearance and Aesthetic of the building.
Distribution: The distribution of utilities in a building such as plumbing, HVAC, etc.

ETSC 101 Chapter 6 Hacker
Address the following with respect to your Topic:
Different Types
Different functions/purposes/Applications
Explanations of how it works, what the system looks like.
Impacts on surrounding environment
Maintenance and Renovation
Maintenance of structures is due to:
Natural Degradation
Natural Disaster
Life Cycle Requirements
Renovation of structures is due to:
Need for style update of the building
End of life cycle for the entire building (ex: bridge with 50 year life)
Maintenance describes repair of system components while renovation describes the repair of the entire system at once.
