Infrastructure Development Cycle

In the DPWH, the development of infrastructure projects (e.g. roads, bridges, flood control facilities and water supply) follows a cycle process consisting of four phases as follows:


It is the process of collecting potential projects with expected return of investments.


    a. Project Feasibility Study

        The feasibility study consists of various investigations and tests necessary to determine whether the project   can and should be carried out and if, so, how and when?

    b. Inclusion in the Medium-Term

        If the project meets the above feasibility criteria, it is considered for inclusion in the medium-term infrastructure program for the period of six years.

    c.  Fund Appropriation

        Based on the medium-term infrastructure program, appropriations for the projects are authorized thru legislation.

    d.  Detailed Engineering

        Detailed engineering of a project under the medium term program is undertaken in preparation for actual implementation under the annual infrastructure programs.

    e.  Inclusion of Project in Annual Program: Programming

Projects proposed for inclusion in the annual infrastructure program are a) those that rank high high in priority within the medium-term program, and b) those that are technically ready for actual implementation during the year (i.e. with substantially completed detailed engineering).


a.  Fund Releases       

          Immediately after the NEDA Board approves the annual infrastructure program in early  November, the DBM issues the Advice's of Allotment (AAs) for the projects in the program on a comprehensive basis.        

b.  Right-Of-Way Acquisition 

          The right-of-way of any infrastructure project, such as road, should be acquired ahead of construction in order not to impede the work.      

c.  Bidding and Contracting   

          In line with the policy of the government to rely on the private sector as the main engine of economic development, infrastructure projects are generally undertaken by contract after public bidding.

d.  Construction          

          Actual construction work is carried out through the Project Management Office (PMO) and the Regional/District Offices.      

e.  Completion and Acceptance         

  Project completion is the transition from the development to the operational stage. Completion reports and as-built plans are prepared for the submission to the implementing office heads,to management, and to    funding institutions.           

f. Payment      

          Due and demandable claims are processed by the DPWH either at the Central, Regional or District level, in accordance with existing government budgeting, accounting and auditing rules

    a.  Operational and Maintenance

National roads and bridges, major flood control structures, and related facilities of national importance remain under the responsibility of the DWPH during the operational phase.  The Regional and District undertake the maintenance of the facilities generally by administration.

    b.  Impact Evaluation

         Impact evaluation or post-project appraisal is an attempt to assess the results of a project and, as a function of the results, of the means employed to achieve them.
