Bridge construction is a complex process requiring meticulous planning, engineering precision, and specialized equipment. At ASF Corporation, we handle every aspect of bridge development from initial concept to final inspection, ensuring structural integrity, safety, and longevity for all our projects across Dhaka and beyond.
Our methodical approach to bridge construction follows these essential stages:
Planning and Design: We begin with comprehensive planning and design, determining the bridge’s purpose, location, span length, anticipated loads, and site conditions. Our engineers conduct thorough feasibility studies considering community needs, traffic flow patterns, environmental conditions, and safety criteria.
Detailed Design: After establishing the initial concept, our team develops complete structural specifications, determining exact dimensions, performing strength calculations, and defining appropriate materials. We also outline long-term maintenance strategies to ensure maximum safety and functionality throughout the bridge’s lifespan.
Permit Acquisition: Before breaking ground, we handle all necessary regulatory approvals and permits, navigating Bangladesh’s construction regulations with expertise and efficiency.
Site Preparation: Our crews meticulously prepare construction sites, clearing vegetation, excavating ground, and establishing access roads and temporary facilities to ensure smooth operations throughout the project timeline.
Foundation Construction: We excavate and prepare foundation areas designed to support the bridge’s weight and structural requirements, creating a solid base for the entire structure.
Substructure Development: Our team builds piers, abutments, and support structures designed to carry the superstructure load according to precise engineering specifications.
Superstructure Erection: Once the substructure is complete and properly cured, we assemble and install girders, beams, or arches according to design specifications, creating the bridge’s main structural framework.
Deck Construction: We construct bridge decks using reinforced concrete, steel, timber, or composite materials based on project requirements, creating the surface that will serve as the roadway.
Finishing and Detailing: Our work includes installing expansion joints, safety railings, parapets, drainage systems, lighting, and other essential components that ensure functionality and safety.
Testing and Inspection: Before opening to traffic, we conduct rigorous inspections and load tests to verify structural integrity and compliance with all safety regulations and design requirements.
ASF Corporation utilizes various construction methodologies tailored to each project’s unique requirements:
Cast-in-Place Concrete: We build bridges on-site using concrete poured and cured in place, ideal for custom designs and challenging terrain.
Precast Concrete Construction: For faster completion times, we manufacture bridge components off-site in controlled environments, then transport and assemble them at the construction site.
Steel Construction: Our lightweight, durable steel bridges can be built quickly, with components fabricated off-site and assembled on location.
Cantilever Construction: For spanning wide rivers and deep valleys, we employ the spectacular cantilever technique, using the static principle of the balance beam to eliminate the need for falsework when conventional methods reach their technical and economic limits.
Incremental Launching: Our team expertly coordinates and executes incremental launching methods for bridges requiring specialized construction approaches.
Mobile Shoring with Integrated Formwork: We utilize advanced mobile shoring systems with integrated formwork to enhance efficiency and precision.
ASF Corporation has the expertise to build various bridge types to meet specific project requirements:
Reinforced Concrete Bridges: Utilizing loose reinforcement for strength and durability in standard applications.
Prestressed Bridges: Employing prestressing techniques to enhance structural performance and span capabilities.
Cable-Stayed Bridges: Constructing sophisticated cable-stayed structures for longer spans with distinctive architectural appeal.
Composite Steel Bridges: Combining steel and concrete elements to optimize strength-to-weight ratios and construction efficiency.
Timber Bridges: Building environmentally friendly wooden bridges for appropriate applications and settings.
Suspension Bridges: Erecting towers on-site while fabricating main cables and suspenders off-site for efficient assembly of these iconic structures.
Beyond new construction, ASF Corporation specializes in extending the life of existing bridges through comprehensive maintenance and rehabilitation services:
Bridge Deck Repairs and Waterproofing: Restoring and protecting bridge deck surfaces to prevent water damage and deterioration.
Bridge Strengthening: Implementing structural reinforcements to increase load capacity and extend service life.

ASF Corporation has successfully completed numerous bridge projects throughout Bangladesh, including:
Each project in our portfolio demonstrates our commitment to excellence, innovation, and durability in bridge construction.
In Bangladesh, three main types of deep foundations are commonly used for bridge construction in riverbeds: caissons, cast-in-situ bored piles, and tubular bored piles (with or without concrete infill). For larger bridges, large diameter (1200mm) cast-in-situ RCC bored piles are quite common, while viaduct spans typically use 1000mm diameter cast-in-situ bored piles.
Bridge construction in Bangladesh faces several challenges including complex soil distribution across river crossings, heterogeneous soil conditions in both vertical and horizontal directions, predominance of silt-sized materials containing significant percentages of mica, unstable riverbanks, and rapid river scour that can significantly change the cross-section and course of rivers.
Based on past projects, bridge construction in Bangladesh typically takes around 3-4 years. For example, the bridge project at 70th Km on Labukhali-Dumki-Boga-Dashmina-Golachipa-Amragachi Road had a planned construction period of 4 years (2014 to 2017).
The Bangladesh Bridge Authority (BBA) is the primary government organization responsible for overseeing major bridge construction projects in the country. It was established in 1985 for carrying out the purposes outlined in the Bangladesh Bridge Authority Ordinance.
River training works and guide bunds are essential components of bridge construction in Bangladesh to confine river flow within the bridge length. These structures require bank protection from waves, bed scour, and ensure slope stability. Guide bunds typically comprise heavily protected sand slopes designed to control the flow of rivers.
Bridge foundations in Bangladesh are designed considering the local soil conditions, hydraulic flow, and scour potential. For large bridges, techniques such as skin and base grouting are employed to improve pile capacity. Special considerations are given to the presence of mica in soils and the potential for rapid scour in the loose alluvial soils typical of Bangladesh’s rivers.
For large bridges in Bangladesh, Osterberg (O-cell) tests have been performed to interpret pile capacity and derive skin frictional resistance and base resistance of large diameter piles. These tests have revealed that considerable improvement in pile capacity can be achieved through skin and base grouting techniques.
Bridge projects in Bangladesh typically provide significant economic benefits including increased economic activity, enhanced educational opportunities, and overall regional development. For example, the bridge project at 70th Km on Labukhali-Dumki-Boga-Dashmina-Golachipa-Amragachi Road was projected to have a Benefit-Cost Ratio (BCR) of 1.30 and an Economic Internal Rate of Return (EIRR) of 18.64%.
Environmental impacts of bridge construction are assessed through specific mitigative and monitoring measures. Projects undergo environmental impact assessments to ensure they will not lead to any long-term irreversible adverse impacts on adjacent environmental quality. These assessments are part of the feasibility study phase of bridge projects.
Bridges in Bangladesh face maintenance challenges related to scour, slope stability of approach roads, and deterioration due to environmental conditions. The Roads and Highway Department (RHD) has developed Bridge Maintenance Management Standards to address these issues, though finding professional Bridge Inspectors in Bangladesh remains difficult due to poor marketability of this profession.
