Lesson
Inadequate consideration of the project sites' topography and geological conditions in project feasibility studies and detailed engineering designs could lead to unexpected cost increases during implementation. There was a significant cost increase in land acquisition and resettlement due to changes in the project scope and additional land acquisition that needed to be undertaken because of the complex geological conditions in some sites resulting in increased civil works costs in some packages.

Lesson
Detailed market analysis through strategic procurement planning and accurate cost estimates could prevent unexpectedly low bids, leading to significant project savings. Under this project, it is noted that low bids did not negatively affect the quality of construction.

The risks associated with single-tranche loans can be mitigated through proper management of the loan proceeds and control of the project cost. The ADB loan was featured to have a single tranche disbursement arrangement to address currency mismatch and hedge financial risks arising from foreign borrowing. In the early stage of project implementation, the full amount of the ADB loan ($90.8 million) was disbursed as an advance and exchanged to local currency.

Lesson
A monitoring and evaluation framework for regional and long-term impacts need to be established and applied to all regional projects related to corridor development. The project, a GMS highway expansion project, had regional impacts through international corridor development. Meanwhile, the project also had development impacts on local people through enhanced access to social and economic opportunities.

Lesson
The project offers a good implementation management model for similar ADB-financed projects to learn from. This project was completed ahead of schedule with no cost overrun, an exception among ADB-financed road projects in other member countries. The government has strong capacity and experience in managing such highway projects. Compiling experiences and lessons learned from this project and disseminating them to other member countries would enhance the overall efficiency of ADB-financed projects.

Lesson
Flexibility in project design is required to respond to changes in subproject scale and adapt capacity support to the changing needs. This project was implemented across eight provinces, with significant differences in the size and scope of provincial waterworks (PWW) subprojects and local capacities. A flexible design was crucial to its successful implementation.

Lesson
Opportunities for advance procurement remain limited in Cambodia because financing is unavailable for detailed engineering designs in advance of loans. This limits the preparatory actions that could be undertaken to improve project readiness. Solutions such as a project design facility are being considered and may be possible from 2024 onwards.

Lesson
Establishing well-staffed and operational project management units (PMUs) and project implementation units (PIUs) as early as possible is essential for effective implementation. Timely recruitment and mobilization of project implementation consultants will also ensure that technical resources are in place to support the PMUs and PIUs. Delays in consultant recruitment and high turnover in specialized areas need to immediately addresses as these could adversely impact project activities.

Institutional arrangements to implement mandatory safeguard polices and reporting systems and gender action plans need to be established in the initial stages of the project. This is to avoid potential delays which could adversely impact project adherence to social and environmental safeguards and gender equality results. Adequate human, rechnical, and budgetary resources and strict monitoring by the PMU and ADB are required to ensure compliance.

Managing implementation during emergency situations requires a flexible and adaptive approach. Amod the COVID-19 pandemic, PMU and PIU systems were based on (i) adjusted work practices, (ii) limited staff movements and restrictions on international and national travel, (iii) changes in consultant resource use and approach, (iv) supplier delays and reduced contractor capacity, and (v) assessments of the impact on implementation timelines, and planning extensions, as required.

The transition of PWWs into independent corporate entities requires adequate preparation to ensure they have the capacity, technical and financial management skills, and resources for viability and sustainability. To support this transition, the PMU adopted a phased and practical approach, implementing vital actions with training and technical support. The PWWs developed business planning and financial reporting systems and adopted supervisory control and data acquisition systems. The PMU has identified the first PWWs that are considered ready for the next step as a corporate entity.

Extensive upstreamCapacity development is required to address municipalities and contractors’ limited capacities and understanding of complex design, build, and operate (DBO) contracts. Those limitations delayed the procurement and implementation of the wastewater treatment plant (WWTP) contract under this project.
