Tauhid; Bin Kabir, Sadib An iconic building linking Bangladesh's southwest to its northern and eastern areas is the Padma bridge, which spans the third-largest river in the world with a complicated topology. By boosting production, employment, transportation, and the national and regional economy, this multipurpose bridge is projected to boost GDP growth by 1.2%. This study's primary goal is to pinpoint the greatest challenges encountered during Padma Bridge's construction and explain how sustainable management procedures might be put in place to address such difficulties. The most challenging tasks included finding a suitable site, dealing with complex river morphology, overcoming geotechnical barriers, controlling unfavorable environmental conditions, assembling massive construction equipment and materials, maintaining the construction schedule, and dealing with the COVID epidemic. To resolve these construction challenges, massive river training works and a unique pile foundation design that consists of six floating heaps and one center pile with the largest raking pile in the center were both utilized. To get around the difficulties in superstructural design, longer pre-assembled steel truss girders, pre-tensioned Super-T girders in viaducts, seismic isolation devices, and the largest friction pendulum bearings in the world were all made. Only a small number of people experienced COVID-19 without any fatalities or causing delays in the construction schedule since the Project was kept operational during the COVID-19 period by tightly enforcing the COVID laws and limits on people's mobility. The field of construction management would undergo a paradigm shift with this sustainable management of construction-related difficulties, which might later be used to design more intricate bridges.

To establish direct communication with those areas Government of Bangladesh Constructed Padma Multipurpose Bridge with the provision of road and rail traffic at the upper and lower deck of the bridge respectively. The Padma Bridge Rail Link Project (PBRLP) is the main passage connecting the East and the West of Bangladesh and is also a part of the Bangladesh-China-India-Myanmar corridor. This line is a single-track passenger-freight railway with a total length of 168.6 km. For the first time in Bangladesh, State of the Art technology ballast less tracks in Padma Bridge, its approach to viaducts and other viaducts are being adopted for providing a smooth operation for both freight and passenger traffic. Precast and prestressed long sleeper embedded in cast in-situ track slab ensures a maintenance-free track system for the railway. PBRLP, once completed will restore the missing link with the Trans-Asian railway and will provide a platform for connecting with the Dedicated Freight Corridor (DFC) of India in future. It will also contribute to the Gross Domestic Product (GDP) of the country by 1.0%.

S.; Moniruzzaman, S. M.; Hossain, Tahsin Reza; Bosunia, Shamim Z The Padma Multipurpose Bridge (PMB) is one of the biggest megaprojects of Bangladesh connecting one third of the country with the capital city, Dhaka. The infrastructure is expected to produce considerable uplift on the nation’s transport system, the national and regional economy, employment, household income, and ultimately, poverty reduction. From construction and river management points of view, it is the most difficult and engineering innovationintenstive project in the world. Hence the Padma Multipurpose Bridge (PMB) required analytical, computational and experimental studies. In this work, a 3D Finite Element (FE) model of the actual PMB containing a single (6x150m) 900m modules has been developed in MIDAS Civil, a commercial computer program for bridges. P-y soil spring model following API guideline has been developed to conform flexible support system of the bridge pier. Following BNBC 2020, the bridge's performance has been evaluated for the 475-year, 975 years, and 2475- year return periods for Service Level, Design Basis and the Maximum Credible Earthquake (MCE), respectively. The forced based design shows that the bridge pier reached only 28% and 36% of its axial and shear capacity respectively for an earthquake return period of 2475 years. On the other hand, the pier has reached a maximum of 41% of its total shear capacity for the same seismic level.

Feroze; Ahmed, Tanvir; Rahman, Md Tauhid Ur The Padma Bridge, being the largest infrastructure development project of Bangladesh, required extensive environmental safeguards to make the dream project of Bangladesh environmentally sound. Threat to biodiversity particularly breeding and migration of HIlsha (Tenualosa ilisha) fish, safe disposal of 50 million m3 of dredging spoils, disturbances and displacement of wildlife, conservation of biodiversity, plantation of trees lost to the project, control of construction related noise, air and water pollution, occupational health and safety of the workers were the main environmental impacts of the project. An Environmental Action Plan (EAP) with effective protective measures was successfully implemented. Environmental monitoring of quality of both surface and drinking water, ambient noise level, concentration of PM10, PM2.5, CO, ozone, oxides of nitrogen and sulfur in ambient air, disposal of domestic, construction and hazardous wastes, disposal of dredged spoils, use of personal protective equipment (PPE) and safety at work sites were conducted regularly by a team constituted for this purpose throughout the project period and protective measures were adopted as and when required. Increased flow, water level and temperature in Padma River due to climate change were considered in the design of the Bridge. A wildlife sanctuary has been established in the project area for flourishing of flora and fauna in the protected environment.
