Lesson
Accurate cost estimates, including for contingencies, and effective utilization of loan savings are critical to the attainment of intended project results and timely financial closing. The actual contract price was lower than the amount estimated because of the inaccuracy of the engineering cost estimate and contingency estimates. Cost savings, however, were effectively utilized through minor changes in the project, further enhancing the achievement of project outcomes and outputs. Eligible expenses should be clarified early on, so as not to delay the project financial closing.

Resource constraints can impede the participation of smaller firms in ADB procurement as well as hinderCapacity development of counterpart agencies. Smaller firms struggled to respond appropriately in some bidding processes, which resulted in their being considered ineligible to participate. The project implementation unit experienced resource constraints, which hindered sustainedCapacity development throughout the project and the participation of outer islands officials in the training activities.

Climate risk assessments must be undertaken during project preparation, with results factored into the project design and budgets. The project experienced unforeseen landslides, pointing out the need to (i) improve climate modelling at design stage to incorporate potential climate change impacts on frequency and severity of landslide hazards for projects located in mountainous areas, and (ii) ensure adequate budget or contingency for potential increase of land acquisition during implementation.

Specificity of intended outcome is essential to enable programming, innovation, and cycles of project improvement. The project’s outcomes were broadly defined and lacked clear pathways detailing how the outputs would interact with each other and achieve the outcomes. The vagueness is likely part of the reason that the design had significant gaps and flawed assumptions on how the activities would lead to the intended outcomes.

Government’s effective and responsive implementation of the program and use of funds highlighted the importance of being able to adjust allocations as demanded by the crisis. The government successfully utilized its ADB countercyclical loan to support its relief and stimulus program under its two pandemic emergency decrees and funds (FY2020 and FY2021). In particular; the Cabinet responded rapidly to the successive waves of COVID-19; allocating and reallocating budgets to work plans and projects where they were most needed at any one time.

While the timely and effective utilization of project savings can improve outcomes, it would be best to ensure reliable cost estimates at appraisal to avoid complications and mitigate implementation risks. Cost savings during implementation prompted two requests from POWERGRID, the borrower and executing agency of this project, to use available loan funds through minor scope changes. This enhanced project results and final outcome, particularly as ADB and POWERGRID were able to swiftly meet the requirements and provide timely support for the implementation of the scope changes.

Overconservative cost estimation during the implementation of the multitranche financing facility (MFF) tranche projects may reduce the funding availability for other investments and result in low utilization of the approved MFF amount. Tranche 2’s actual total cost was $64.97 million, 60% of the budgeted amount, and ADB’s loan disbursement was only 61% of the committed amount.

Flexible reallocation of loan proceeds to critical civil works can enhance project relevance and effectiveness. A minor change in scope was approved for the reallocation of loan proceeds from project administration savings and secondary consulting services to the civil works contract. The new allocation enabled additional works on the coastal boulevard impacted by the storm but kept the loan size within its original limit.

Considering the construction costs and number of subprojects as tentative when there are significant technical unknowns that cannot be determined during the design stage will help mitigate the risks and facilitate the implementation of sector loan projects. Under this project’s preparatory technical assistance (TA), cost estimates were prepared under conditions of significant technical information gaps for all potential bridge sites.
