Lesson
Wide time gaps between the finalization of construction cost estimate, initiation of the bidding process, and awarding of contracts should be avoided as these could lead to time and cost overruns. There were significant time gaps of 4–5 years between the finalization of the DPRs, including cost estimates and the completion of the bidding process. Besides causing startup delays, this also led to higher contract costs in comparison to the engineering estimates.

The envisaged institutional arrangements for safeguards need to be fully functional from commencement to the closure of projects. This would allow the safeguards performance of projects to improve, as was the case with the environmental performance of this project which improved over time, with increased monitoring and coordination by the project staff.

Stakeholder relationships need to build on established mandates and be insitutionalized to effectively contribute to and ensure project success. The project benefited from local project management offices (PMOs) building effective relationships with key stakeholders in the road safety ecosystem, including traffic police and education bureaus. Although successful, this approach relied on relationships among different agencies to implement a safe system approach without any mandate.

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.

Lesson
Zero changes in project staff and implementation arrangement contribute significantly to smooth project implementation. The key staff of the project management office and implementing agencies remained unchanged throughout the project preparation and implementation periods. This, along with the absence of any scope changes, ensured smooth implementation of the project. The experience can be repeated in future projects through appropriate institutional measures and project implementation arrangements.

Stakeholder involvement in project design and advance preparation of the consultant terms of reference and procurement packages strengthen the effectiveness and efficiency potential of projects. Close involvement by the executing agency and project colleges allowed for an in-depth discussion of outcome and output indicators, as well as of the cost estimates reflecting the local context and implementation capacity of the executing agency and project colleges.

Lesson
Inaccurate estimation of quantities in the detailed project reports (DPR), required for project processing in India, can raise project costs at the same time push back construction periods. There was a huge difference between actual quantity requirements based on site-specific conditions and those indicated in this project's DPRs. Because of insufficient estimations in the bill of quantities, contractors had to put a huge claim for the revision of rates and work quantity. Given this, care must be taken in preparing the DPR and estimating quantities.

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.

Lesson
Significantly lower contract prices for civil works could lead to project completion delays.Civil works contract prices for this project were, on average, 30% below the initial estimates. The winning contractors, all private companies, encountered financial challenges during construction as the low unit prices meant that increased work resulted in financial losses. Faced with this situation, the contractors were reluctant to mobilize additional resources and accelerate the construction progress.

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.

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.
