Haiti will receive international aid worth $10bn from donors in a concentrated effort to rebuild the quake-hit nation.
A total of $5bn will be used within the next 18 months and an additional $3.9bn is being sought for reconstruction initiatives.
The funds had been raised by the United Nations and its member nations.
UN secretary-general Ban Ki-moon also appealed to donors to provide $11.5m over the next ten years to help the Caribbean nation.
Ban said only 50% of the $1.4bn funding allocated for reconstruction work are available.
International engineers inspecting Haitian buildings found them lacking in building codes and that houses had been constructed poorly with no government regulations.
