1. ENGR330-1 Engineering Service Projects Interior Walls Benefits: IMPROVEMENT: Provide walls DURABILITY: Walls should last >10 years given normal use SUSTAINABILITY: Simple design, use available materials, easily repaired COST:No added cost for HCS Image from Project Background: The Peltan Christian School in Haiti currently has only one large room. This presents two problems: 1. The Haitian government requires schools to have classrooms 2. Classes distract each other Objectives: Evaluate needs Chose wall type Evaluate wall cost Develop wall plans Execute wall construction 1

2. ENGR330-1 Engineering Service Projects 2 Needs: Divide 24’ x 48’ room into 4 classrooms Easily movable, open hall or classroom setup Low cost Withstand some tipping force Block vision and some sound between rooms Solutions: Pre-fabed folding with slider track Hanging wall segments, hook onto rafters Freestanding segments with a large base Rolling walls Cabinet walls Accordion walls “+” pattern
