Padma Bridge Approach Roads & Facilities Supervision Project
The Padma Multipurpose Bridge Project (PMBP), approximately 40 km south west of Dhaka, comprises a new fixed crossing of the Padma River in Bangladesh, which will consist of a bridge approximately 6.15km long, major river training works and approximately 13.6 km of approach roads and bridge-end facilities, including toll plazas, service areas and offices. The main bridge structure would carry a 4-lane highway, and have provisions for future installation of a single track dual guage rail line as well as other facilities including gas, power transmission and tele-communication lines. The main bridge is a two level steel truss superstructure with road traffic on the upper level and rail on the lower level acting compositely with a reinforced concrete deck slab. A brief description of the Main Bridge and River Training works (RTW) components of the project along with some schematic drawings is provided in Attachment 1. A pre-feasibility study of the proposed project was undertaken in 1999 comprising surveys, studies, preliminary designs, cost estimating, economic and traffic evaluation. This was followed by a feasibility study in 2003-2005 which comprised further studies and recommended the crossing be built at a location between Mawa and Janjira. This feasibility study formed the basis for the Government of Bangladesh (GoB) to proceed with the design and construction of the bridge. The project is divided into two phases: (i) Phase I- Detailed Design and Contract Procurement; and (ii) Phase II — Construction. The Design Consultants submitted the Final Design Report on July 5, 2011, which has been approved by the competent authorities. The bridge designs has been vetted by a separate consulting firm hired as the “Checking Engineers”. The Final Design of all i,e 5 contracts has been completed and Bid Documents prepared accordingly. The Government of Bangladesh has decided to take over/take up the project from its own fund. Accordingly 3(three) of the 5(five) contracts i,e contract no-3 Janjira approach road and selected bridge end facilities, contract no- 4 Mawa approach road & selected bridge end facilities and contract no- 5 service area-2 has been awarded to the contractors and works are going on accordingly. The current estimated total cost of the project is about US$ 2972.06 million. This document sets out the Terms of Reference (ToR) for Phase II, the construction phase of the project. The BBA intends to hire an international consulting firm to undertake overall construction supervision of the contract no-1 & contract no-2 i,e Main Bridge and River Training Works (RTW) covering the roles of the “Project Manager” and the “Engineer’s representatives”. A separate construction supervision consultant (CSC) has already been engaged for contract no 3, 4 & 5 i,e Janjira approach road and selected bridge end facilities, Mawa approach road & selected bridge end facilities and service area-2. All these activities will be financed by the Government of Bangladesh (GoB). Detailed Description of Actual Services provided by your staff: Consultancy services for construction supervision/project management are required to ensure that the construction of Main Bridge and River Training Works is implemented in an economical and efficient manner consistent with internationally accepted standard and practices with high standards of workmanship, specified quality of materials within the stipulated construction period and in conformity with the approved drawings and specifications, safeguard standards achieving objectives of the project with value for money. The main tasks and activities of the Construction Supervision Consultants (CSC), covering the pre-construction, construction and post construction stages of the Main Bridge and River Training Works would include, but not limited to, the following: A.

Rajapara–Payra Port 4-Lane Road Project
Narrative Description of Project: Bangladesh’s external trade is growing on average at 9.2 percent per annum and by 2020th country’s total annual sea borne trade will be in the range of 75 to 80 million tones and 2.75 million twenty-foot equivalent unit (TEU) containers. These volumes are beyond the capacity of Bangladesh’s existing sea ports at Chittagong and Mongla. In particular, Chittagong presently handles around 92 percent of cargo and by 2020 it will have reached full operating capacity. Even a possible expansion of these two ports will not be sufficient to handle forecasted increases in trade volumes, and over the next decade this shortfall could reach around 50 percent of the country’s capacity needs. Given these constraints, the Government of Bangladesh has determined that the Rabnabad Channel at Kalapara Upazila in Patuakhali District is a naturally suitable place for constructing a seaport. This site has been subsequently named Payra Port. Payra Port is located on the West bank of the Rabnabad Channel, approximately 5 nautical miles upstream from harbour mouth. There are no restrictions regarding length and beam and the site with its outer anchorage can potentially cater to vessels with 14.5 metre draught. Considering the handling of future trade volume and export/import growth, Govt. of the People’s Republic of Bangladesh decided to build a new sea port and an Act was passed on National Parliament on 05 Nov 2013. Honorable Prime Minister inaugurated 3rd sea port at Lalua Union, Kalapara Upazila of Patuakhali district on 19 Nov 2013.
