• Goal was to improve construction quality while providing safe housing

• Clear quality standards through the Engineering Repair Manual

• Training of Engineers, Contractors, and Masons in improved techniques

• Community-Based Construction Management and Quality Control

• Final Certification ( Under MTPTC authority)

MTPTC Repair Guideline

• Repair back to better than pre-earthquake condition

• ASTM STP 1180 Report• 300% Ductility Increase • Readily available materials in Haiti

270 engineers trained on Damage Evaluations: 80 engineers trained on conducting Repair Assessments 11 Contractors trained to build better 550 Haitian professionals trained on the new repair techniques
