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.

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.

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.

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.

An alternative approach for the Completion of projects halted by the closure of the availability period of MFF-financed loans needs to be explored. This is especiallly important for projects with considerable stranded investments (e.g., stranded investments in the Ramazon HPP included $3 million for transmission line and $3 million for site Preparation). To continually implement the Ramazon HPP, the PNG Power Ltd.
