2. Air Barrier Paper This air barrier paper is a plastic-like material. However, it has certain fibers in it that allow moisture to escape from the inside of the wood behind it to the outside wall. It also created to block any air infiltration, hence, air barrier paper.
3. Attic Ventilation Attic ventilation is needed to allow heat to escape from the house. We all know heat rises and during the summer and the heat needs to get out of the house so the house won’t be 100 degrees. Certain types of ventilation allow that heat to escape. Ridge Vent Gable Vent
5. Backhoe A backhoe is a hydraulic excavating machine consisting of a tractor having an attached hinged boom, with a bucket with movable jaws on the end of the boom. It is used to remove earth from the top surface in order to start a foundation at a lower elevation. The backhoe featured here has a bucket width of 4 feet.
6. Batter Boards Batter boards are a temporary frame built just outside the corner of an excavation to carry marks that lie on the surface planes of the basement that will be built in the excavation. The boards behind me in this photograph were actually the batter boards, but the frame would be set up like this concrete formation.
13. Brick Sizes 15 1/2” These bricks are extremely long and don’t have much height to them. Since none of the names in book match this brick size, the closest one would Norman. Brick Size est.: 3 5/8” x 2 ¼”x 11 5/8” . 2 1/4”
14. Brick Sizes These bricks are examples of Modular brick size. Brick Size: 3 ½” x 2 ¼” x 7 ½” 7 ½” 2 ¼”
15. Bulldozer A bulldozer is a heavy, driver-operated machine for clearing and grading land, usually having continuous treads and a broad hydraulic blade in front. As the definition states, this piece of equipment is used to excavate tree stumps, rocks, and earth in order to smooth the jobsite’s land.
18. Cladding(cont.) Wood Shakes I’m guessing these are wood shakes because there is no standard size to them and they do not line up perfectly like shingles do.
20. Window Code Stair Code Since my window is below 72 inches in height, the regulation of a 24 inch widow sill is not required. It also raises to 24 ½ inches and the width of it is 35 ¼ inches. Therefore, my window meets the residential code handbook. The stairs meet the code in all aspects. The stair is 42 ½ inches in length, 11 inches for each tread, it rises 7 ½ inches, and the nose only overhangs an inch. According to the handbook all of these are acceptable to the code. Code Requirements
21. Concrete Joints Control Joints are intentional, linear discontinuity in a structure or component, designed to form a plane of weakness where cracking can occur in response to various forces so as to minimize or eliminate cracking elsewhere in the structure.
22. Concrete Joints Isolation Joints are concrete joints that are separate from another state of concrete joint. For example this column has an isolation joint for more support but the foundation will be laid over it too. This joint is isolated from the slab.
23. Concrete Masonry Unit 3 1 Also known as a CMU, a concrete masonry unit is a block of hardened concrete, with or without hardened cores, designed to be laid in the same manner as brick or stone; a concrete block. Its sizes vary but the most common used in construction is 8”.
24. Concrete Masonry Unit 12” It also comes in 12”,10”, 6” and 4” sizes too. All of them are 16” long and are all nominal measurements. They are used to support rebar running up the side of a building or to be the main support wall of a building.
31. Transformer Box Service Head The transformer box controls the current of electricity running into a building. It changes the voltage of the current as well. A service head transfers electricity through wires into a building from an outside source such as power lines. Electrical Components
32. Meter Service Panel Meters count the usage of electricity throughout a building. Most of them count kilowatts per hour to bill the consumer. The service panel is like a fuse box for the house. Sometimes the power may go out and people have to “flip the breaker” for the electricity to reset. Electrical Components (cont.)
33. Duplex Receptacle Duplex receptacles are also known as outlets or plug-ins. They are used to give an electric current to certain pieces of equipment that require electricity in order to work. Electrical Components (cont.)
39. Front End Loader A front end loader is a machine that is used to help excavate a jobsite by either removing dirt or flattening the ground. It differs from a backhoe and a bulldozer because it is like a combination of both of them. It can dig into the earth like a backhoe, but it can also smooth the land out like a bulldozer.
40. Gypsum Board Gypsum board is an interior facing panel consisting of gypsum core sandwiched between paper faces. It is also called drywall or plasterboard.
41. Heat Pump The unit circled with red is the compressor and the unit circled with orange is the air handling unit. The compressor has a fan that moves outside air across heating or cooling coils in the house. The air handling unit contains the coils that control the temperature. One advantage to this system is a quick response time and one disadvantage is it’s very noisy and needs to be away from bedroom windows.
44. A lintel is a beam that carries the load of a wall across a window or door opening. Steel Lintel
45. Raked Mortar Concave Mortar Raked joints are tooled and I think mortar type S was used on this house. The mortar was starting to weather which means it’s not a strong weatherproof mortar. Concave joints are tooled as well and I think type N mortar was used for the weathering and support for this building. Mortar
46. Oriented Strand Board Oriented Strand Board (OSB) is a nonveneered panel producted used for sheathing during construction. It is made of long shredded wood particles that is constructed into three to five layers. The layers are alternated facing each other so the grains go against each other for more durability.
51. Plywood Plywood is a wood panel composed of an odd number of layers of wood veneer bonded together under pressure. The layers are laid on each other with the grain perpendicular to the previous layer and glued together.
52. Radiant Barrier The radiant barrier is reflecting heat from the roof back to the outside of the building.
53. Rebar The rebar here is ½ inch diameter rebar and is referred to as #4 rebar. The purpose of the deformations in rebar is for better grip within the concrete when it dries. It will have a stronger hold if the rebar is grooved for concrete to form around it.
54. Gutter- A channel that collects rainwater and snowmelt at the eave of a roof. Downspout- A vertical pipe for conducting water from a roof to a lower level Splash block- A small precast block of concrete or plastic used to divert water at the bottom of a downspout Steep Roof Drainage
56. Steep Roof Materials Underlayment is a layer of waterproof material between roof sheathing and roofing. It keeps the water off of the wood sheathing and is also known as “tar” paper. Clay Tiles
57. Steep Roof Materials Metal Panel Roof Metal panels are usually fabricated with aluminized or galvanized steel with long lasting polymeric coatings. They also require no specialized equipment on the jobsite.
66. Vapor Retarder A vapor retarder is a layer of material intended to obstruct the passage of water vapor through a building assembly. It is normally placed on the bottom side of insulation to prevent the water coming into the ceiling.
67. Waterproofing Waterproofing is another barrier to prevent water from coming in the house. It is laid in between the foundation wall and air barrier paper and is normally found around the base of a house. This particular type is loosely laid.
68. Weep Hole A weep hole is a small opening whose purpose is to permit drainage of water that accumulates inside a building component.
69. Welded Wire Fabric Personally I couldn’t find welded wire fabric on a jobsite, however it is a grid of steel rods that are welded together, used to reinforce a concrete slab.
70. This is a double hung window because both windows can raise and lower. This is a hopper window because it opens inward and is hinged on the bottom. Windows
71. This is a casement window because it is hinged on the side and it opens up to the outside. Windows (cont.)
