TRANSCRIPT
Plan, Sketch, Drawing• Before starting new construction or
repair jobs of any size, a plan, sketch, or drawing should be made to reduce costs, save time, improve quality of workmanship, and determine the need for the construction or repair projects
Specifications• The best way to guarantee
high quality materials and workmanship in construction projects is to include specifications in plans and contracts
Time to Be Completed
• Time to be completed is a major consideration in planning agricultural construction or repairs because of the seasonal nature of farming
Square Foot• Many building materials
are sold by the square foot or in units that combine square footage such as a square or a sheet
Length x Width• Calculate number of
square feet by multiplying length times width in feet
• Example: 8 feet x 10 feet = 80 sq. ft.
Square of Shingles• A square of shingles has
enough shingles to cover how many square feet
• 100 sq. ft.
Estimating Cost• One story building costs
can be estimated by using sq. ft.
• Example: 1000 sq. ft. x $10/sq.ft. = $10,000
Plans• Plans drawn on paper save
time and money because changes are faster and less expensive to make on a plan than on the real structure
Types of Drawings• Types of drawings used in
construction include sketches, hand drafted drawings, and computer assisted drawing
Isometric• Three dimensional view
that shows object as a whole instead of parts and shows the object in a form similar to a picture, is drawn to scale
Perspective• Is similar to isometric
because it is three dimensional and appears on the drawing as it does to the eye, but it is NOT drawn to scale
Purpose• Purpose of constructing a
project in agricultural mechanics shop is to provide hands on learning or application of what has been leaned in class
Bird Houses• Beginning students should
start with relatively small and simple projects such as nail boxes, tool boxes and bird houses
Trailers• Advanced students should
choose more challenging projects that use more skills such as storage buildings, trailers, and farm structures
PaintedProjects that will be exposed
to weather should be made from treated wood or should be painted with exterior paint to provide protection for the wood
Depends on Use• The width and thickness of
wood needed for a project or for certain parts of a project depend on the use that will be made of the project
Depends on Use• A work bench or a
livestock or horse barn requires larger sized wood than a bird house or nail box
Starts at the Bottom• Because of the nature of
construction and the law of gravity, construction of a building starts at the bottom and continues to the top
