Lesson
Time overruns could occur because of (i) the introduction of a new contracting modality that require longer lead time and stronger staff capacity, (ii) rebids due to the termination of nonperforming contracts, and (iii) challenges in the management of contractual disputes.

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.

Implementation arrangements are critical to the success of projects. Initial implementation progress under this project was mixed: while output 2 was progressing according to schedule, outputs 1 and 3 were not. At ADB's instance, the implementing agency (IA), the Baise University instituted reforms in the implementation arrangements, with the Vice President of the university replacing the project leading groups.

Lesson
Efforts to train EAS and IAs in ADB procurement procedures will do little in developing institutional procurement capacity with the persistence of staff turnover in these agencies. In this project, frequent turnover of key staff members prevented the training from reaching all those responsible for developing requests for proposals, formulating evaluation criteria, and reviewing bids against the criteria. Consequently, procurement capacity remained low.

EAs and IAs commonly perceive the low-cost option as the preferred option. However, in the case of consultant selection and civil works contractor selection in thisproject, this perception was debunked by poor contractor performance and issues with payment.

Lesson
Wage issues significantly affect the demographics of the teaching projection. The project observed a shift in the demographics of teachers, with an increase in non-minority teachers and a decrease in minority teachers. This shift can be attributed to local wage disparities, which incentivize local women, including ethnic minorities, to seek employment opportunities in higher-paying regions such as Nanning and Guangdong.

Lesson
There is a need to provide employability training and support to enhance the employment prospects of women even in non-skilled jobs. During project implementation, many employment positions were created, primarily benefiting ethnic minorities, including minority women. These positions mainly involved infrastructure work with lower technical skill requirements and cleaning work. While these opportunities were valuable, experience from the project highlighted the need for employability training and support to these groups.

Reductions in government counterpart funds must be documented especially to review and derive learnings on how these impact the scope and implementation of ADB-financed projects. A reduction in government counterpart funds and increase in the domestic loan amount under this project was not documented by ADB. The EA indicated a policy change in 2015 that affected the scope of government counterpart funds; however, documentation of such a policy change was missing.

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.
