However, these impacts will require 4-5 years to be realized considering the construction period of the Bridge and the time lag of investment and induced effects. The impact of the trans-border connection through the Padma “corridor” will further enhance the nationwide benefits as a whole. 12. Implementation Program Two methods, namely Conventional Contracting and Design-Build, were considered for the procurement method, with advantages and disadvantages of both considered. Although the Conventional Contracting method is advantageous for the Owner (i.e., JMBA); it might take three years longer than GOB’s expectation to start the project in fiscal year 2006/2007. To expedite implementation and reduce the planning widow, an Overlapping Conventional Contracting has been recommended. This recommended method simultaneously ensures fairness in the contractual bidding process. 13. Operation and Maintenance Planning for Padma Bridge O&M issues for the Padma Bridge were also studied with special focus on current practices in existing major bridges in operation as toll roads, including the Jamuna, Bhairab, and Paksey Bridges. Typically, the highway operator’s tasks included in the routine maintenance of the project highway are inspection (routine, periodic and special), cleaning (road surface, associated facilities and road accessories), vegetation (tree/forest control, lawn control and slope vegetation), some traffic accident recovery works, traffic regulation, the monitoring program on bridge deck levels, riverbed scour, etc., and maintenance of utilities and equipment. The O&M in Padma Bridge would require the maintenance of river facilities, which includes monitoring the riverbank conditions and bank protection works, data analysis, diagnosis, program and the execution of maintenance work. As a result, an organizational structure and staffing of about 160 for the O&M of the project highway has been recommended, mainly taking into account the Jamuna Bridge practice.
THE FEASIBILITY STUDY OF PADMA BRIDGE FINAL REPORT – EXECUTIVE SUMMARY - MARCH 2005 VII 14. Conclusions and Recommendations (1) Construction of the Padma Bridge is viable from a macro-economic perspective. It will contribute to the development of the regional economy and to the reduction of poverty. At the same time, the contribution of the bridge has great significance in terms of developing an international transport corridor. Therefore, this should be an urgent project to be implemented at the earliest opportunity. (2) Taking the importance of the international transport corridor into consideration, the Padma Bridge shall have four bi-directional lanes to satisfy the Asian Highway Standard and include the necessary space for future railway provision in the medium term. An increase of about US$80 million will be required for the provision of the railway, but the EIRR value of this project remains 14.80%, making it economically feasible. Further study on the railway provision is urgently required.
