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.

Door/Window Framing• Doors and Windows

have extra reinforcement.

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.

HVAC

• Heating

• Processes

• Air Conditioning

• Insulation

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.

Construction Impacts

• Environmental

• Social

• Political

• Economic

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.
