Code Requirements Room <ul><li>The International Building Code states that the egress window must have a clear opening of at least 5.7 square feet, a clear width minimum of 20 inches, and a clear height minimum of 24 inches. The bottom clear opening cannot be more than 44 inches above the finished floor. The window we analyzed had a width of 35 inches, and the height was 25-1/2 inches. The clear opening is 6.54 sqare feet and the window is 36” above the finished floor. </li></ul>
<ul><li>The International Building Code states that a set of wood-framed interior stairs has to meet certain codes. The code states the the minimum lengths for tread, the portion that we step on,10 inches and the riser cannot exceed 7-3/4 inches. We analyzed the stairs in Ben’s house to see if they meet code. The photograph above shows the stairs that I analyzed and the riser dimension was 7-1/2 inches and the tread dimension was 11-1/2 inches. If we measured correctly, the stairs meet code. </li></ul>

Concrete Masonry CMU and Brick Comparison <ul><li>Concrete masonry unit, or CMU is a hardened block of concrete that is molded into a specific shape and is used primarily in foundations, retaining walls, and fire places. CMU units are made in a wide variety of shapes and sizes, but the typical dimensions are 8 x 8 x 16. These dimensions are nominal, or appropriate, the actual dimensions are 7-5/8 x 7-5/8 x 15-5/8. An important aspect about CMU is that a standard eight inch high CMU is equal to three courses of modular brick. Another advantage is the time a builder saves using CMU instead of brick. The picture above illustrates the fact that a standard eight inch tall CMU block is equal to three courses of modular brick. </li></ul>

Electrical Components Meter The meter calculates how much electricity a certain building uses.
Electrical Components Service Panel The service panel, usually located in a metal box, includes circuit breakers that distribute electricity that runs to a duplex receptacle.
Electrical Components Duplex Receptacle This is where appliances are plugged in.
Front End Loader <ul><li>A front end loader is a powerful earthmoving machine. A large hydraulic scoop is located in the front, which is usually the same length as the machine itself. The scoop is used primarily for lifting and loading dirt. This scoop defines the major difference between the bulldozer and the front end loader. </li></ul>
Gypsum Board <ul><li>Gypsum board is a prefabricated plaster sheet material consisting of gypsum core sandwiched between two paper layers. Gypsum board is also known as wallboard, drywall, or sheetrock. The picture shows a gypsum wall in which the joints have been taped and mudded. </li></ul>
Heat Pump Compressor/Evaporator <ul><li>The compressor/evaporator is located on the exterior of the building. The main purpose of this device is to take outdoor air and move it across coils containing refrigerant to change the temperature of the refrigerant. This device can also work in reverse to cool a building in the summer months. One advantage of a heat pump is the ability to heat a house rapidly but the disadvantage is the it can also be noisy when air travels through the ducts. </li></ul>
Heat Pump Air Handling Unit <ul><li>The air handling unit it located on the interior of the building and the main purpose of this device is to move air through ducts which distribute air to each room. </li></ul>
Insulation Batt Insulation <ul><li>This is usually made from fiber glass cut to fit onto framing cavities. Batts are provided on sheets, while blankets come in rolls. </li></ul>
<ul><li>Spray foam is a chemical substitute for insulation methods like fiberglass. This barrier can hold in air and heat, keeping houses warm. </li></ul>
Insulation Rigid Board Insulation <ul><li>Is manufactured in panels that make it easy to clad a large area. It also resists water and rot from locations in the ground. </li></ul>
Lintel <ul><li>A lintel is a horizontal beam used as a finishing piece over a door or window. Can be made of stone, concrete, or steel. </li></ul>
Mortar Tooled Joint <ul><li>A masonry joint where the mortar has been worked with a tool to create a finish effect . </li></ul><ul><li>This tooled joint is 3/8”. </li></ul><ul><li>This is used as a brick veneer on a hardware store. </li></ul><ul><li>I would guess that the mortar is type-N. </li></ul>

<ul><li>OSB is an engineered wood product formed from layers of wood flakes in specific orientations. OSB panels have no internal gaps or voids. </li></ul>
Plumbing Lavatory The typical sized piping used to drain a lavatory is 1-1/2” diameter.
Plumbing Plumbing Vent Vent through the roof for plumbing. The purpose of this vent is to keep the water level in the P-Trap under the sink level. The water needs to stay in the P-Trap to keep the toxic sewer gases from entering the building. It also lets the water drain freely.
<ul><li>Plywood is a type of engineered wood made from thin sheets and is glued together at right angles from each other for greater strength. The term veneer is defined as a thin layer of wood that is glued together to make a thicker sheet of wood. </li></ul>
Radiant Barrier <ul><li>Radiant barriers or reflective barriers inhibit heat transfer by thermal radiation. </li></ul>
Rebar <ul><li>A rod or bar used for reinforcement in concrete. A pattern is rolled onto them which helps the concrete get a grip on the bar. This rebar is ½” thick so it would be called a number 4. </li></ul>
<ul><li>Gutters are the metal channels that are attached to the roof edges and used to draw water down and away from the house and its foundation. </li></ul>
<ul><li>A vertical pipe for carrying rainwater down from a roof gutter. </li></ul>
Steep Roof Materials Underlayment Underlayment is a flexible, protective barrier for the roof sheathing; its main function is to protect the roof from rain water before the roofing is applied. It also serves as a permanent second layer of defense.
Vapor Retarder <ul><li>Vapor Retarder is a thin, continuous layer of material that is placed on insulation to obstruct the passage of water through a building. It is placed in such a way to make it as seamless as possible. The most common materials used are plastic sheathing, aluminum foil, and craft paper. Vapor retarder is always placed on the warm-in-winter side of insulation. </li></ul>
Waterproofing <ul><li>Waterproofing is placed on the underground area of a foundation wall and it serves to resist standing water under pressure. There are about five different categories of waterproofing, which include: liquid-applied membrane, loosely laid membrane, fully adhered membrane, cementations, and Bentonite clay. The picture shows an example of liquid-applied membrane. Some advantages of this type of waterproofing are that it is easy to detail around penetrations and it can take the form of any shape. </li></ul>
Welded Wire Fabric <ul><li>Welded wire fabric is fabricated from a series of wires arranged into different sized squares used to reinforce concrete . Welded wire fabric, referred to as WWF. </li></ul>
