摘要：	In Georgia, quality and sustainability issues jeopardize the long-term usefulness of the Samtskhe-Javakheti road project. The Millennium Challenge Corporation (MCC) funded the rehabilitation of about 217 kilometers of road linking the previously isolated Samtskhe-Javakheti region with Tbilisi, the countrys capital, and reducing the driving time from 8 14 hours to 2 hours. The project was intended to increase export s from the region, integrate people in the region with the rest of Georgia, and expand trade with Turkey and Armenia. However, the urgency to meet fixed time frames resulted in problems implementing the projects quality assurance framework. For example, the construction supervisor did not have enough staff to properly monitor construction and ensure quality. Despite several recommendations from MCCs independent engineer, MCC and its Georgian counterpart, the Millennium Challenge Account (MCA-Georgia), did not adequately increase the number of construction supervisors, which resulted in pavement defects in parts of 5 of the 11 road sections and deterioration of structures such as drainage and retaining walls. One 15-kilometer section contained enough defects that the road had to be completely repaved. Furthermore, much of the repair work was to be done in the contracts 1-year defects liability period, after the compact closed and at a time when MCC no longer had oversight authority. Although MCC took steps to ensure the road projects sustainability, the Georgian government has demonstrated limited ability to keep the road operational and maintained.
