**GENERAL INFORMATION** - CSI- **Construction specifications Institute (Organizes).** - In 2004 CSI has **50 divisions with 6-digit classification**. - **Type 1** IBC Occupancy group is most fire resistant. - Earth material goes from **Boulders, Cobbles, Gravel, Sand, Silt, Clay** - **2 hands to lift boulders, 1 hand to lift cobbles, gravel can be picked up between fingers, sand is too small to pick up 1 at a time, and silt and clay is too small to see individual particles.** - Excavation types are **benched which goes down in angled steps and shored which is hard sided.** **FOUNDATIONS** Shallow foundations- Individual Footings (single pillar), Wall Footings (T), Combined Footings (Multiple pillars), Mat Foundations (large even groups). Deep Foundations- Drilled pier, Socketed caisson, End bearing pile, Friction Pile - Storm pipe ends are the **spigot (bare) and bell (holder end)** - **Excavator** digs bigger holes than Backhoe. **CONCRETE** - Concrete is **Cement + Aggregate + Water.** - As strength increases the water to cement ratio decreases. - Slump test measures **workability** of concrete while wet. - **\# for rebar size is 1/8^th^ inch** Ex: 4= ½ in and 8=1 in. - Segregation- **when Concrete separates into individual components.** - Rock Pocket or Honeycombing- **concrete isn't workable enough and creates hollow pockets in concrete.** - For screeding concrete workers use a **sawing motion.** - Control Joint **hides cracks** in concrete but does not stop them while Isolation joints **connect where separate pieces of concrete meet.** - Precast concrete has **shorter casting times.** - **Grout** is used to fill voids between columns and footings and protect the metal. **WOOD/ LUMBER** - In trees dark rings are in the **late summer/ fall**, and Bright bigger rings are in the **spring/ early summer.** - Moisture content in which mold can't grow is **below 20%.** - Lumber is priced in **BOARD FOOT.** - End nail is one piece of wood being nailed into the other, face nail is two faces of the wood touching together and toenail is angled in. - **Wracking** is when a house angles, **Overturning** is when a house picks up on one side and **Sliding** is when a house shifts on the slab. - Most common spacing for framing is **16" or 24".** - **Sole Plate-** Connects slab to a wood framed wall. **MASONRY** - **Corners** are the start of laying masonry walls. - In VERTICALLY reinforced masonry walls, there is **rebar surrounded by grout in a block cell.** - Mortar is made of **Portland Cement, Hydrated Lime, Water, and Aggregate.** - **Head Joints**- Vertical Joints in block walls, **Bed Joints**- Horizontal Joins in block walls, **Coarse-** One horizontal row of bricks, **Wythe**- one vertical stack of bricks, and **Collar Joint-** vertical joint between wythes. **STEEL** - 3 most used noncombustible structural materials are **Steel, Concrete, and Brick.** - Shear tabs- **Where beams are designed to fail.** - Diagonal Bracing- **Triangular geometry.** **ROOFING** - Roof rise per run is **12" of run for 2" of run.** - Shingles are placed **From Top Down** - Edge of roof that is not over an air-conditioned space where the soffit meets the fascia is the **eave.** **GLASS** - Annealed glass is cooled slowly and used in double glazed windows. - Heat strengthened glass is annealed glass that is reheated and then cooled quickly and is 2x as strong. - VT- **Visible light transmittance,** SHGC- **Solar Heat Gain Coefficient,** LSG- **Light to Solar Gain Ratio.** **Exterior Wood** - Wood absorbs water so a barrier is needed to prevent it between the exterior and interior wood. - Flashing is impermeable membrane that can be made of metal or synthetic material. - Vented siding- siding that has spacers to allow for air flow like weeps on a brick wall. - Ice barrier- when ice is melted on the roof it needs to fall off instead of soaking into the plywood, so an ice barrier is needed. **Walls** - Aluminum is forced through a **die like pushing toothpaste through a tube.** - **Curtain walls (Storefront) -**glass panels used in front of single-story retail buildings and is supported by the buildings structure and carries no vertical load. - **Curtain Walls (Window Wall)-** used in low rise buildings, can span between floors and is the boundary between inside and outside. They are anchored to floor slabs or other structural elements and are not supported by the frame. Installed from bottom up. - **Curtain walls (Curtain Wall)-** nonstructural outer cover and protects building from elements and is used for esthetics. Supported by the buildings floor slabs and hung from the frame and are hung from top down. **INTERIOR PARTITIONS** - Finishes go from 0 to 5 with 0 being the least finished and 5 being the most. Level 2 is what you would see on things like garages and level 5 is something that is used for a sleek super flat look with shiny paint. - Paint- **Binder + Solvents + Pigments + Additives.** - Wood stains can be water or oil based with water being less penetrating but dries faster and is easier to clean up than oil.
