Evaluates project to reconstruct the principal 69 kv transmission line which was damaged by Hurricane David in the three Dominican Republic cities of San Cristobal, Valdesia, and Bani. This final evaluation, which is attached to a PES (PD-AAH-371-A1), covers the period 11/20/79-7/4/80 and was conducted by the contractor, the engineering firm of Charles T. Main. The project was completed in six months. Minor delays in material deliveries caused short recesses in the construction effort. Had these delivery problems not occurred, the project would have been completed in shorter time with some labor cost savings. Construction began in early 12/79 with materials which were available in the inventories of both the Dominican Republic Electric Corporation (CDE) and the Puerto Rico Electric Power Authority (PREPA). During construction, Main observed the anchor installation, structure erection, hardware installation, and the wire stringing and made recommendations to PREPA, who then made improvements accordingly. In the mountainous regions a helicopter was used to transport and erect the structures and to string the wire. All of the conductor was installed manually. During the initial stages of construction, Main noted that grounding was not done on some structures. This grounding was later completed and no deficiencies exist at this time. PREPA”s accounting system was found to be excellent for establishing a basis for the invoicing. Invoices, which represent everything except for the accounting adjustments of the PREPA contract, have been approved for approximately $100,000 less then the original PREPA budget. PREPA was supported reasonably well by the CDE in the areas of excavating holes, surveying, and in other areas of line construction. It may be more efficient to have these smaller items totally under PREPA”s control. Main feels the effort of all parties contributed to the successful completion of the project.
