Lesson
Sound identification and valuation of costs and benefits in the economic analysis can provide more realistic economic internal rates of return (EIRRs) to indicate a more accurate state of project viability. The economic analysis in the RRP and PCR underestimated the value of the project outputs, particularly the economic benefits of the solid waste management component, which led to a low EIRR. Willingness-to-pay $2 per month for solid waste removal seems too low and unreasonable considering the substantial health and environmental benefits that such removal likely provides.

Lesson
Poor quality detailed project reports (DPRs) have led to a host of problems, including cost escalation, delayed implementation, and increased land acquisition. Therefore, care should be taken while preparing DPRs to avoid issues during construction.

Lesson
Climatic constraints, available working seasons over the year, difficult terrain, availability of experienced local labor, and availability of construction materials need to be adequately considered in deciding the construction completion period. As this was not the case under the project, the Public Works Department was forced to extend the contracts' duration to be able to complete the civil works contracts.

Lesson
As they can lead to time and cost overruns, wide time gaps between the finalization of the estimate, initiation of the bidding process, and awarding of contracts should be avoided. Significant time gaps of 4–5 years between the finalization of the detailed project reports, including cost estimates and the completion of the bidding process were incurred in this project. This led to higher contract costs in comparison to the engineering estimates.

Difference in the number of affected assets identified at appraisal and the actual count during implementation can lead to delays in safeguards implementation, which can be worsened by the executing agency's lack of capacity and reliance on short-term, limited consulting inputs. There was a 24% increase in the number of affected structures and households during implementation compared to the estimate at appraisal.

Lesson
ADB and the executing agency should agree on all terms related to the payment of vulnerable allowances to affected people during project appraisal. Vulnerable allowances under this project could not be paid on time due to the absence of recognition of ADB's resettlement plan provisions in country practice.

Gender equality and social inclusion (GESI) mainstreaming in Nepal's Ministry of Public Infrastructure and Transport (MPIT) is challenging. The MPIT developed and approved the guidelines for GESI. However, operationalizing the guidelines in all ministry operations has been challenging, mainly because of the need to orient staff at different levels. The government's budget allocation for mainstreaming GESI ensures strong ownership, but the budget is not adequate for institutionalizing GESI in the transport sector.

Lack of ownership of design by the executing agency can lead to implementation delays. The project was the first ADB supported project where the design and construction supervision contracts were split. Reviewing and deciding on design changes was delayed because of a lack of ownership over design by the construction supervision consultant's and the Department of Roads lack of timely decisions.

Complex projects are better designed and implemented if there is a clear government sector plan that is fully supported both at the national and provincial levels. This was demonstrated by the country's railway development plan and its financial allocations. The national government successfully reached out to a private bank for cofinancing, and the provincial governments had a strong buy-in through their smooth and timely implementation of the land acquisition and resettlement plan.

In projects where institutional and financial capacity is relatively strong, ADB's financial additionality can be demonstrated by instilling proper design and implementation of social and environmental safeguards in infrastructure projects.

Lesson
Land acquisition should be embedded in transport policies. As of 2022, the Prime Minister's Rural Roads Program (PMGSY) was being implemented with no land acquisition. Where land is required, only voluntary-based possession is allowed. If sufficient land cannot be pooled on a voluntary basis, geometric design is being compromised. These locations may become accident black spots. Thus, policy amendment is needed in cases where sufficient land for improvement is unavailable voluntarily; permission should be granted for acquisition of land.

Lesson
Early and continuous involvement of financial staff and coordination with development partners are crucial to ensure aptly designed financial management arrangements. This is particularly true for multi-donor funded programs that require harmonization of financial management systems. As these were lacking in this project, significant financial management issues were experienced during implementation.

Shifting of utilities need to be included in civil works contracts to avoid delays in construction and ensure that all required utilities are shifted. Contracts should also include precautionary measures to prevent contractors from taking advantage of utility shifting issues in their favor.

Reduced counterpart funding and increased use of loan proceeds will facilitate timely implementation and project closure. This project was designed with substantial counterpart funding from governments. While demonstrating strong ownership, this affected implementation as the governments were unable to disburse the budget on time. Besides reducing the requirement for counterpart funding, sufficient documentation and incorporation of counterpart fund releases in the audited annual financial statements can help facilitate the financial closing of future projects.

Opportunities for knowledge exchange and sharing among resident mission staff need to be included in the design of regional projects. Regional cooperation and integration elements were not included in this project. As a result, resident mission staff missed the opportunity to share knowledge and exchange experiences that would have enhanced their capacities.
