Concrete JointsControl Joint An intentional break in the surface of concrete to create a point of weakness where cracking can occur in order to minimize cracking elsewhere in the concrete.
Concrete JointsIsolation Joint A joint that extends through the slab that completely separates the slab from a wall or column and is filled with a sealant. They are used to compensate for the different rates at which differing materials expand and contract, in this case a concrete sidewalk and a brick wall.
Concrete Masonry Unit 1 CMU= 3 Brick A CMU is a block of hardened concrete laid using mortar. They usually contain hollow cavities that can be filled with rebar and concrete grout to reinforce the wall. They provide a means for building economical retaining, basement and crawlspace walls. They can be painted on both sides and function as interior and exterior wall as seen at Wal-mart. Typical nominal dimensions are either 8”x8”x16” or 8”x12”x16” (HeightxDepthxLength)

Electrical ComponentsPower Pole with Transformer and Service Head The service head provides a watertight means for the power lines from the transformer to enter the meter box The transformer steps down the voltage from distribution voltage down to 120 volt that is used in residences.
Electrical ComponentsMeter and Service Panel The electric meter measure the amount of electricity that flows into a house and is the point at which the electric system is no longer the responsibility of the utility but that of the homeowner/contractor. The service panel is the point that distributes the current to all of the branch circuits in a building including lights, appliances, and outlets.
Electrical Components Duplex Receptacle Point at which 120v devices can be connected to a homes electrical system.
Front End Loader Front end loader- Piece of heavy equipment used to load soil, sand, rock, asphalt, debris and many other materials into dump trucks or other pieces of equipment using a large rectangular bucket.
Gypsum Board Interior facing panel consisting of a gypsum core between 2 paper faces that is finished with joint compound and creates a seamless interior wall ready for paint.
Heat Pump Advantage: extremely efficient Disadvantage: Does not operate well at very low temps and may require a backup system Compressor/ Condenser The air handler is located inside the house and conditions the air by heating or cooling via refrigerant and the condenser/ compressor unit outside Transfers the heat from inside the house into the atmosphere by compressing refrigerant.
Insulation Batt/blanket insulation Rigid Board Insulation Loose-fill Insulation Foam Insulation Material of low thermal conductivity used to reduce heat flow in or out of a building
Lintel A piece of angle iron or precast concrete that carries the load of a wall over the opening of a window or door

Mortar #2Concave Tooled Joint 3/8” Apartment complex Type N-used as a masonry veneer
Oriented Strand Board OSB- a nonveneered panel product made by gluing and pressing small strands of wood in alternating directions. OSB is used for roof sheathing, wall sheathing, and subfloors.
PlumbingLavatory and Water Closet Lavatory drain piping- 1 ½” Water closet waste piping- 3”
PlumbingRoof Vent and Sink Drop-in Sink Vent piping allows air to enter the drain and waste piping to break the vacuum that would be created by a sealed pipe and allow the water and waste to flow freely
Plywood Wood panel made up of multiple veneers of wood glued together in alternating directions under high pressure. A veneer is a very thin sheet of wood. Plywood
Steep Roof Drainage Gutter- Metal or plastic channel that collects rainwater or snowmelt at the eave of a roof and channels it to a downspout Downspout- Vertical pipe that carries water from a roof gutter to a lower level, usually a lower level of the roof or the ground. Splash Block Splash block-a small block of precast concrete or plastic used to divert water at the bottom of a downspout away from the foundation of a building
Steep Roof Materials Underlayment and Clay Tile Underlayment Clay Tile Roof A layer of waterproofing (building felt) installed between roof sheathing and the roof. It temporarily protects the OSB sheathing before the roof can be installed and provides another layer of defense against water for the finished roof

VaporRetarder A Vapor Retarder slows the passage of moisture through a wall cavity to prevent condensation in a wall which can lead to mold. It should be placed on the side of the insulation closest to the interior since the hotter more humid air inside contains the moisture that is trying to work its way into the wall.
Waterproofing Waterproofing- material placed to resist the penetration of water in a structure, in this case a foundation. The type pictured is liquid applied spray-on.
Weep Hole A small opening (missing head joint or string laid in mortar) whose purpose is to permit drainage of water that accumulates behind a brick wall
