Agricultural Structures and Farm Buildings Quiz

Study Notes

Importance of Farm Structures

Farm buildings are essential for integrated rural development.
Knowledge in design and construction optimizes farm management.
Improved animal production demands appropriate housing for livestock.
Enhances living standards for rural populations.

Types of Farm Structures

Farm Houses: Residences for farmers and their families.
Livestock Buildings: Include barns for beef cattle, dairy, horses, hog houses, and poultry houses.
Crop Production Buildings: Greenhouses used for plant cultivation.
Product Storage Buildings: Granaries, silos, and storage for vegetables and fruits.
Food and Crop Processing Buildings: Facilities like milk houses, slaughterhouses, grain driers, and pasteurization plants for food processing.
Equipment and Supplies Buildings: Garages and farm shops for storing tools and machinery.
Miscellaneous Structures: Include fences and manure pits.

Building Materials

Wood: Commonly used due to strength, durability, lightweight, and aesthetic qualities.
Concrete: Widely used for its robustness.
Roofing Materials: Various types utilized depending on structure needs.
Metals/Structural Steels: Provides structural integrity and strength.
Fasteners: Essential for assembling materials.
Others: Includes tiles, clay bricks, and glass.

Lumber Measurement

Pricing is commonly based on board feet (fbm).
One board foot equals a volume of 1' long x 1' wide x 1" thick.
Formula: fbm = (Length x Width x Thickness) / 12.
Circular logs measured with: Bd.Ft = (D - 4)² x L / 16, where D is the smaller diameter.
Lumber sizes less than 2”x2” are priced linearly, not by board foot.

Strength Groups of Philippine Timber

Class I (High Strength): For heavy-duty constructions like bridges and girders.
Class II (Moderately High Strength): Used in heavy-duty furniture and cabinets.
Class III (Medium Strength): Suitable for general framing and medium-grade furniture.
Class IV (Moderately Low Strength): For light constructions like moldings and wall boards.
Class V (Low Strength): Used for pulp paper production, woodworking, and light construction items.

Plywood

Composed of multiple veneer layers with alternating grain directions.
Thickness varies, typically between 3.2mm to 20mm, with standard dimensions of 1.20m in width and up to 2.40m in length.
Types of plywood:
- Softwood Plywood: Commonly used for structural applications.
- Hardwood Plywood: Used for aesthetic finishes, usually with one face in hardwood.
- Marine Plywood: Designed for water-resistance and external use.

Lumber Classifications

Lumber: Wood that has been processed into boards, planks, or timber.
Rough Lumber: Unplaned wood used in its natural state.
S2S and S4S: Planed lumber with smooth surfaces.
Slab: Rough lumber cut along the grain, maintaining a flat surface.
