Lesson
Performing an adequate level of due diligence and risk assessments at the early stage of project preparation increases the quality of project design and readiness. For example, preparatory work for procurement planning and administration of abnormally low bids (e.g., prequalification of bidders) supports and better streamlines the procurement process and avoids substantial changes in a project design and scope.

Lesson
Timely and appropriate changes in scope and reallocation of loan and grant proceeds responding to actual project needs emerging from implementation can help utilize available loan and grant resources in a more targeted and efficient manner to facilitate more activities and deliver more outputs. For example, responding to the government’s request relating to E35 contributed directly to developing an efficient and safer transport corridor between Islamabad, Faisalabad, and Multan for more connectivity between the various parts of the country.

Lesson
The absence of a financial cost-benefit evaluation for the toll revenue-generating motorway is a methodological weakness. The project completion report (PCR) did not explain why it did not conduct a financial cost-benefit evaluation for the toll revenue-generating motorway. This validation notes that the RRP too did not conduct such evaluation.

Lesson
Due diligence for future projects should include developing a thorough understanding of the institutional setup and internal review and approval procedures as well as mapping out effective mitigation measures to minimize delays. This project's implementation was affected by cumbersome approval mechanisms at the executing agency (EA) headquarters for contract variations and extensions. Frequent interventions by ADB and EA top management were required to expedite decision-making.

Inadequate consideration of climatic constraints,working seasons in the project sites, difficult terrain, and availability of experienced local labor and construction materials can cause construction delays with implications on project implementation periods and costs .

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
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.

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
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
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.

The value addition of mainstreaming gender equality in terms of capacity building and awareness raising, and ensuring the participation of women, maximizes project benefits for women. It gives them the opportunity to participate in activities related to urban and water sectors and to develop skills that will increase their livelihood and income-generating opportunities

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.

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.
