Local Road Management Manual 242 simple and easily implementable at the LGU and community levels. The RBIVA is not intended to supersede the more rigorous road and bridge inventory system and the design review. In fact, it is envisioned to take advantage of the results of various analyses including hazard mapping, community mapping, detailed design investigation and testing. RBIVA advocates the development of an infrastructure audit procedure to identify critical infrastructure components and recommend appropriate engineering solutions in the design of new road and bridge infrastructure or in the improvement of existing ones to make them more resilient. RBIVA capitalizes on LGU-based hazard identification and vulnerability assessment using thematic vulnerability maps and other assessment tools as input to design and construction. The RBIVA guidelines are attached as Annex 6 in this Manual.
