- Learn construction principles and best practices for various farm structures.
- Estimate materials, cost, and design parameters for agricultural buildings.
I. Syllabus
- Surveying: Definitions, classification, units, scale, conventional signs; chain survey; taping techniques; compass survey; leveling; contour and topographic mapping.
- Construction Materials: Bricks, cement, sand, gravel, timber, steel, CGI sheets, thatch, concrete, RCC, PCC, centering, shuttering.
- Farm Structures: Foundation, walls, floors, roofs, doors, windows, beams, columns.
- Farmstead Planning: Site selection, insulation, ventilation, layout of dairy, poultry, and swine houses.
- Storage Structures: Grain, feed, and fodder storage, silos, trench, pit, tower silo; greenhouses and polyhouses.
- Cost Estimation: Types of estimates (approximate and detailed), procedure for detailed estimate, rate analysis.
