Lesson
Results-based lending (RBL) is well suited if it is embedded in a wider government-owned and led program. It can be an effective modality for achieving both physical outputs and nonphysical goals. It can also make changes in national policies that go beyond the project’s physical scope. The climate risk assessments, procurement processes, and beneficiary selection criteria used in this program were also applied in non-ADB financed provinces. The instructions issued and policies adopted by the government were “national”in nature and impact.

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.

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.

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
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.

Project Name: Second Strengthening Technical and Vocational Education and Training Project
Report Date:
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
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
Inappropriate design of performance-based maintenance contracts (PBMCs), including unrealistic performance parameters, and limited capacities and understanding of complex contract conditions by project implementers and the bidders alike could delay procurement and cause additional difficulties in project administration.

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.

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.
