Local Road Management Manual 109 i. Implementation and Management. Once properly programmed, budgeted, designed and procured, the civil works are implemented. Whether the civil works are executed By- Administration or By Contract, the local engineering oiffce is in charge in the construction supervision of the project. A unit should be designated to monitor and manage the progress of the project until completion and turn-over; and j. Monitoring and Maintenance. Local road infrastructure should be constantly monitored after completion and turn-over. This is to ensure that defects can be corrected immediately either by the contractor or by the LGU. There should be periodic inspections and monitoring to ensure that appropriate maintenance works are implemented to the right sections at the right time. 2. Surface Treatment for Local Roads 2.1. Common Surface Treatment Options Typical road works being undertaken by LGUS are discussed in this section. To avoid any ambiguity and confusion, it is important to have a clear deifnition of appropriate treatment options for a given local road condition. The reference guidelines for local gravel road rehabilitation are attached as Annex 3A, while the sealing of asphalt pavement is in Annex 3B, and the sealing for concrete pavement is in Annex 3C. A summary of common surface treatment options for local roads for typical physical conditions are listed in Table 4.1 for gravel pavement, Table 4.2 for asphalt pavement, and Table 4.3 for Portland cement concrete pavement (PCCP). The surface treatment options regardless of pavement type are discussed and deifned in detail in the next section.
