Lesson
Substantial cost overruns could result from inadequate detailed design, new legislation (e.g., banning slow-moving traffic from highways), changes in pavement composition to address climate change impacts and overloading, constructability issues, unforeseen project features, and road safety and traffic issues.

Lesson
Adequate project readiness and accurate designs are critical for large infrastructure projects. Lack of these could cause delays, i.e., this project encountered a delay of over 2 years in finalizing the detailed design for the major civil works contracts and delays in procurement. Furthermore, inclusion of additional scope of works and delays in land acquisition and resettlement plans, and COVID-19 impacts hindered timely implementation.

A geo-fabric reinforced seal could be replicated to provide more robust waterproofing and as a strain-alleviating membrane for treating road surface cracks. The geo-fabric reinforced seal installed for a 500 m length of the project road on a pilot basis proved to be an effective spray sealing technique for treating badly cracked and distressed pavements, particularly where crack movements are slow.

Similar projects in similar contexts can learn from the following Implementation lessons learned from the[project: (i) potential startup delays need to be anticipated when developing the project Implementation plan and the contract awards and disbursement projections, withmitigating measures identified; (ii) engaging a single detailed engineering design consultant for projects covering multiple provinces can cause delays;and (iii) use of local consultants could expedite the awarding of civil works contracts.

Lesson
Government budget regulations, particularly on official development assistance (ODA), the main source of ADB funding, need to be fully considered during appraisal as these could cause disbursement delays. In 2015, the allocation of ODA funds to project Implementation units was late and in 2016 no funds were allocated. This meant delays in project Implementation.

It is critical that the risk assessment and management plan of the project preparatory technical assistance in the tourism sector incorporate measures to be taken in case of future pandemics. The COVID-19 pandemic led to delays in realizing project tourism benefits. Nevertheless, the ensuing pent-up demand from domestic and foreign tourists seems likely to lead to increases in future incremental visitor numbers, visitor days, and visitor expenditure from each of the subprojects. These increases could contribute to the financial sustainability of the subprojects.

Land acquisition procedures, processes, consultations, and reporting are complex in Viet Nam, not least because of the number of agencies involved. Therefore, more time, energy, and expertise need to be allocated to project land clearance and subsequent resettlement compensation.

The impact of the cross-border facility (CBF) in the project completion report. Data on traffic and trade flows in and out of Cambodia can provide a before and after assessment. This helps in determining the impact and benefits of improving a CBF.

Lesson
The supporting technical assistance was assessed successful but was let down by the lack of institutional ownership, which can often be the case. For ADB’s future projects, it is important to focus more attention on the design and implementation of such assistance by closely following the consultants’ outputs and ensuring that the government is fully aware of their results

In-depth analysis of the sector’s constraints and challenges both internally and externally, including the institutional arrangements and policies, can provide more realistic implementation of reforms focused on road maintenance.

In terms of project design, in-depth analysis of various loan modality options and risks assessment, taking in consideration the ountry’s huge capacity and institutional gaps, can help design an appropriate loan modality. For example, a sector lending, which can also run for a decade and sustain capacity support to the sector, requires a sector analysis that covers a thorough analysis of the factors that affect the performance of the sector, including policy, institutional or regulatory frameworks, as well as the sustainability of the investment.

Given the flexibility of the multitranche financing facility, if necessary, regular updating and revisions of project design and monitoring frameworks, including baseline data, are expected; thus, proper documentation of these changes can help improve assessment at completion. In addition, assessment of project impacts critically depends on the collection and analysis of project and other data. The establishment of a project performance management system is crucial in this regard.

Projections about the impact of road projects should be realistic and adequately consider the accessibility of the roads to be built to communities. The impact statement in the design and monitoring framework about increased access to markets, jobs, and social services in the 4 project provinces should have been restricted to the 10 districts along the project roads, as the project roads could not generate impacts in farther areas. Performance Indicators and targets should also consider data availability and baselines that proved to be limited in at least one of the project provinces.
