BUILD YOUR HOUSE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Construction Worker
-They basically build the house
-All other positions tell them what to do
Building Permit
-Need a permit to build any buildings
-You have to get them from City Hall (public works department)
Ground Testing

-Make sure the soil is safe to build on
-This is the Geo-Technical Engineer job
Start the Building
-When you start the building you start with footings
-Connects it to the soil
-Should be twice as wide as foundation
-Metal rods are placed through the footing to strengthen (rebar)
-Responsible for the supplying of all material, labor and equipment
-They hire everyone and get all services possible for building the structure
-The foundation contacts footings and earth
-Must be able to hold the structure
-Concrete/cement blocks
-Almost all have Rebar
-Spraying a water resistant substance (black tar) on foundation
-Also sometimes uses rubber coating
-Foundation drains are put around the perimeter
Basement Slab
-Smooth durable surface for basement floor and also supports foundation walls against earths pressure
-After framing has been completed the job is about 35- 40% complete

-The cost of a house is figured by the square foot, so the more square feet you have the more your house will cost.
-Making steep roofs, hips and valleys will add to the framing cost.
-Framing has to be done correctly all the time otherwise, drywall will not be flat, floors will squeak and doors will not close properly
Floor system
-In framing, a platform or floor is built on the foundation that was previously built by the construction workers.
-The structure (which is the house or the building) is bolted to the foundation with anchor bolts and held down with straps. Floor joists are made from 2x8 - 2x12. The best choice for floor trusses are composite "I" beam joists.
-They are the best for the environment, and use up to 60% less wood than a regular solid floor joist and they are straighter, stronger and lighter than traditional floor joists. The floor system will add the strength to the tops of the foundation walls.
Floor Joist Spacing
-The most common spacing of wooden joists is 16” OC (on center).

-16” spacing for installing the subfloor without wasting materials.
Sill Plate
-Attached to the foundation floor
-Fixes problems in the foundation providing a nailing surface
Composite "I" Beam Joists
-They are one of the main choices for floor trusses
-Seeing as they are environmentally friendly
-Also uses a significant amount less than a solid wood joists
-Also very light but very strong on the other hand
-The subfloor is typically made of 5/8”-3/4” tongue and groove OSB or plywood
-Plywood is attached to the joists with nails and glue,this helps prevent squeaks later on after the building has been complete.

Purpose of the sub floor
-It provides a base for finish flooring material

-Gives the carpenter surface where he can lay out and construct additional framing

-Subfloor also adds rigidity to the structure

Roof Framing
-Roof framing provides a base for the roofing materials that will be attached later

-The frame must be strong and ridged or else it will collapse

-Roof framing could also provide a decorative and fancy look to the house

Types of roof framing
