The Foundationhttp://www.construction-resource.com/calculators/foundation.php
• Footers
• Concrete
• Rebar
Footers
• The footer is a concrete stand that serves at the base for a structure. The footer must be dug below the frost line.
Concrete• Concrete is a combination of cement,
stone and sand. It fills the footer and the base of a structure.
Rebar
• Rebar is stuck in the footer to act as reinforcement for the concrete. It adds tensile strength to the concrete.
Framing• Roofing http://www.construction-resource.com/calculators/roof-area.php
• Studdinghttp://www.construction-resource.com/calculators/stud-wall.php
• Door/Windows
Roofing• A roof has many layers. It consists of rafters,
plywood, sheathing and shingles. These layers prevent the roof from leaking.
Studding• Studs are usually 2” x 4” pieces of lumbers
played 16” apart to provide a frame for the wall.
Plumbing Technology
• Drain Pipes
• Supply Pipes
• The Water Pump
• Hot Water
Drain Pipes
• Drain pipes are larger than supply pipes. They must slope ¼” for every foot of pipe. Today they are usually made of PVC.
Supply Pipes• Supply pipes are smaller than drain pipes. The
connection are sealed with solder or PVC glue.
The Water Pump
• The water pump pumps water into your house via the supply pipes. It is usually powered by electric.
Hot Water
• Water is heated by a water heated in your house. It can be electric, oil or gas. Today there are many alternative heating sources.
Heating • Heat is usually provided by a furnace which can
use oil or gas. Heating can also be provide by a central air system.
Insulation• Structures must properly insulated and sealed to
prevent loss of heat. However, a structure must also have ventilation. So a balance must be obtained.
Air Conditioning• Air conditioning draws warm air out of your
house and replaces it with cool air.
Residential Electricity
• Ohm’s Law
• Switching
Systems
• Wiring
Ohm’s Law
• Ohm’s Law is the relationship between voltage, current and resistance.
Switching Systems
• Switching systems allow you to control the electricity in a structure.
Wiring• Wiring
provides a medium for electricity to travel through a structure.
Environmental• Clear-cutting can destroy thousands of trees at
a time. It is done to make room for construction projects.
Social• Construction can provide meeting places for
social events where people can get together.
Political
• There are many laws in place that serve to control the amount of construction that is done in a given area.
Economic• Construction can have many positive and negative economic
impacts on society. It creates jobs and provides shelters and homes for people. But, it is also expensive. If not financed properly construction projects can leave people homeless.
Civil Engineering
• Home Construction
• Commercial Buildings
• Bridges
• Roads, Highways and Causeways
Home Construction
• Residential construction provides homes for just about every American.
Commercial Buildings• Commercial buildings provide a residence
for every business in America. It creates a beautiful city skyline.
Bridges• Bridges have allowed cross-country
transportation to take place for centuries.
Roads, Highways & Causeways• Roads, Highways and Causeways have been an
integral part or organizing our transportation system in America.
