Design
Fabrication of tilt-up building walls Concrete Tilt-Up Panels
Tilt-up can be consider as a simple supported beam. Pw= 20 psf. H= 16 ft. H Total = 19 ft. Length will vary.
Metal Studs
Components
Stud Connections
Partitions
Openings
Insulation
Plasterboard We used: 720 ft metal tracks. 270 Pc Metal studs (10 ft) 180Pc Plasterboard (4’ x 10’) 3600 ft^2 Insulation

SUSTAINABLE BUILT DESIGN Insulated windows Insulation boards (WALLS) Insulation boards (ROOF) Water storage tank
Insulated Windows Low-E windows Reduce energy Cost 25% to 50% Increase confort levels. Eliminate hot and cold spots Reduce noise up to 70%
Insulation Boards (WALLS) Energy Saver Insulates any part of the building Good thermal resistance Reduces heat conduction R19
Insulation Roof Boards Heat insulation, waterproof, fireproof Less smoke and harmful gas Chemical resistance Wide temperature limit R30
Water Storage Tank Advantages: Independent water system Gather water for recycling Irrigation purposes
