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
