The guidelines and procedure for the formulation of the Three-year Rolling Infrastructure Program are prepared to guide all the implementing agencies in the development and updating of the TRIP. This guidance document specifies the procedure and parameters to be considered by the individual IAs for identifying and prioritising their individual programs and projects. Using the consolidated TRIP, the program or project will be submitted to the DBM by INFRACOM for the determination of spending levels for the approval of DBCC and consideration in determining the agency s budget ceilings. This shall then form the basis for the list of infrastructure PAPs that are to be included by DBM in the National Expenditure Program (NEP).
