Detailed Narrative Description of Project:

With the capital growing very fast and increasing traffic on the roads and highways it has been a concern to eradicate traffic congestion with new road alignments and improvement of the existing roads. Thus the construction of a 3^rd Bridge on Shitalakhya River came into reality. As per the requirement of KFAED and the Saudi Funding Agency, the GoB decided to prepare a comprehensive Techno-Economic Feasibility Study Report. The project activities included all necessary technical and economic studies, field surveys, surface and sub-surface investigation, laboratory testing and related works, including those described below to attain the stated objectives.

Bridge Dimensions (summary):

The total length of the structure is 1290m with 400m of Main Bridge (continuous PSC Single Box Girder and PSC Twin Box Suspended Spans in alternate arrangement) and the rest 890m of viaduct portion on both ends.

Span arrangement:

Main Bridge (400m) = 3 x 90m spans + 2 x 25m end spans (PSC Twin Box Girder)

Viaduct Portion (890m) = 28 x 30m spans (RCC Twin box girder & RCC twin box cast-in-situ viaduct) + 2 x 25m end spans (PSC T-girder)

Detailed Description of Actual Services Provided by your Company:

• To review all existing data and studies relating to the proposal to design the new bridges.
• To conduct traffic studies such as existing traffic on road, vehicles on road in study area, traffic survey, characteristics of traffic crossing the rivers, O-D analysis, commodities carried by truck, Bus passengers, car passengers, analysis of present crossing time, Traffic forecast, analysis of transport cost, vehicles operating cost etc.
• To conduct necessary digital topographic surveys and soundings of the two rivers to determine the cross section of the river.
• Study the river hydrology and hydraulics in study area including climate, hydrological and hydrographical study.
• To conduct geotechnical studies and investigations including preliminary seismic study.
• Study the materials required for the bridges including construction materials for approach roads.
• To work out all possible bridge locations and approach embankment including river cross section and provide a comparative study and recommend the best for consideration by the Government.
• Through hydraulic and river morphology study the consultant have made preliminary design for protective works.

The Consultants have also conducted: Preliminary design, preliminary cost estimate; techno-economic analysis; environmental impact assessment and resettlement requirement for the bridge.

The project aimed to ensure expansion of road network to ease the then traffic congestion around Dhaka Metropolitan city. Construction of the proposed 3rd Buriganga bridge commonly known as Shaheed Buddhijibi Bridge (708 m) on Z8208 at Basilla would pave the way to expansion of the Dhaka Metropolitan city towards the west and south-west side.

Bridge Substructure: Pile foundation= 132 nos. of 600mm dia and 96 nos. 1200mm dia; Abutments = 2 nos.; Piers =27 nos.

Bridge Superstructure: Cast-in-situ PC Box Girder

Span Arrangement = 9 x 47m (box girder) + 19 x 15m (viaduct) = 708 m; Approach Road = 2640 m.

Again Dhaka-Chittagong Highway (N1) is the most important traffic corridor and National Highway of Bangladesh Road network. There was only one bridge on Shitalakhya river. The city expanding very fast and traffic congestion over the bridge was a regular phenomenon. To ease the situation, the need for construction of a second bridge over river Shitalakhya, the Sultana Kamal Bridge (1072 m) on R201 at Demra became urgent.

Bridge Substructure: Pile foundation (600mm dia) = 222 nos.; Abutments = 2 nos.; Piers = 33 nos.

Bridge Superstructure: Cast-in-situ PC Box Girder

Span Arrangement = 2 x 61m + 2 x 90m (cantilever box girder) + 10 x 47m (box girder) + 20 x 15m (viaduct) = 1072 m; Approach Road = 982 m

Chittagong is the major port city and the gateway of Bangladesh. It is also the second largest city and the “commercial capital” of the country. The Karnaphuli River divides Chittagong City into two parts. One part is confined with the city and the port, the other part is the area of heavy industry. Current two bridges are not sufficient to accommodate the existing huge traffic flow which is increasing with time. Due to river morphology, siltation on the bed of the Karnaphuli River is a big problem and the major threat for proper functioning of the Chittagong Port. To face the problem on siltation, Bangladesh Bridge Authority (BBA) intends to construct a tunnel crossing the Karnaphuli River instead of construction of another bridge over the same river. The project focused on carrying out of detailed economic and engineering investigation to examine economic viability and technical feasibility for construction of tunnel under the Karnaphuli River. There were 3 alignment options (A, B and C) for detailed study in this feasibility stage and based on the topographic and bathymetric survey, geological investigation, hydrological survey and other associated techno-economic studies the Alignment-C (Patenga-KAFCO crossing) has been recommended by the consultants. The principal part of Alignment C adopts the expressway standard and the approach road adopts the urban trunk road functions.
