Topographic Survey of Bridge/CD Work Site
Accurate topographic surveys form the base of reliable bridge and cross-drainage designs. By mapping terrain, flow patterns, and site conditions with precision, we ensure smarter planning, cost-effective solutions, and faster project execution.
Geotechnical Survey of Bridge/CD Work Site
A strong foundation begins with a clear understanding of the ground beneath. Geotechnical surveys assess soil, rock, and sub-surface conditions to ensure safe, durable, and cost-effective bridge and cross-drainage designs. This vital step minimizes risks, guides foundation selection, and secures long-term structural stability.
Preparation of Drawing
Precise drawings are the blueprint of every successful project. We create detailed structural and construction drawings that translate concepts into executable designs, ensuring accuracy, clarity, and compliance with standards for seamless execution on site.
Preparation of Design Report
Every bridge or CD structure begins with a design backed by evidence. Our design reports combine technical analysis, calculations, and code-based validation into a clear, comprehensive document. Crafted for accuracy and transparency, these reports not only secure approvals but also guide flawless execution on site.
Approval from IIT/NIT/Authority Engineer
For any bridge or cross-drainage project, independent approval is a critical step to ensure safety, reliability, and compliance. We work closely with leading institutes such as IITs, NITs, and designated authority engineers to validate our designs and technologies. Through rigorous review, testing, and certification, every solution is verified for structural soundness, durability, and adherence to national standards. This process not only builds trust with clients and stakeholders but also guarantees that projects are ready for seamless execution on the ground.
Preparation of Detail Cost Estimate
Accurate cost estimation is the foundation of effective project planning. We prepare detailed cost estimates that cover every aspect of bridge and CD works—from materials and labor to equipment and contingencies. By combining technical expertise with real-time market analysis, our estimates ensure financial clarity, resource optimization, and smooth approval processes. This enables clients to make informed decisions and execute projects within budget and timeline.
Preparation of DPR
A Detailed Project Report (DPR) is the roadmap for successful project execution. We prepare comprehensive DPRs for bridge and CD works that include surveys, designs, cost estimates, drawings, and technical justifications. Each report is tailored to meet client and authority requirements, ensuring accuracy, feasibility, and compliance with standards. With clear documentation and practical solutions, our DPRs simplify approvals and provide a strong foundation for timely and cost-effective implementation.
Preparation of Tender Document as per Requirement
Well-prepared tender documents are key to fair competition and successful project delivery. We develop tender documents tailored to client and project requirements, covering technical specifications, bill of quantities, drawings, and contractual conditions. Designed with clarity and compliance in mind, our documents minimize ambiguity, attract qualified bidders, and ensure smooth evaluation and execution.
On-Site Support for Construction Activity
Successful execution goes beyond design—it requires guidance on the ground. Our team provides on-site support to contractors during construction, ensuring work is carried out as per design, specifications, and best practices. From resolving technical queries to monitoring critical activities, we help maintain quality, safety, and efficiency throughout the project lifecycle.
Consulting Services for Construction Activity
Expert guidance during construction ensures projects are executed to the highest standards. We provide consulting services that cover technical advice, quality checks, and process optimization for bridge and CD works. Our involvement helps contractors overcome challenges, maintain compliance with specifications, and achieve timely, cost-effective, and durable results.
Planning and Design
Define Purpose and Location:
Determine the bridge’s function, desired location, and span length.
Assess Site Conditions:
Evaluate soil properties, environmental factors, and potential challenges at the chosen site.
Develop Preliminary Design:
Create a conceptual design that includes the arch shape, materials, and overall dimensions.
Finalize Design:
Refine the design based on site investigations, load calculations, and safety considerations.
Site Preparation
Clear the Area: Remove vegetation, obstructions, and debris from the construction site.
Excavate and Level: Prepare the ground for foundations and other structural elements.
Establish Access: Create roads and pathways for construction equipment and materials.
Set Up Temporary Facilities: Install necessary infrastructure like power, water, and temporary buildings.
Foundation Construction
Excavate Foundation Pits: Dig trenches or pits to the required depth for the bridge’s foundation.
Prepare Soil: Compact the soil or use specialized materials to create a stable base.
Pour Concrete Footings: Construct concrete footings to support the bridge’s substructure.
Install Reinforcement: Place steel reinforcement bars within the concrete to enhance strength.
Substructure Construction
Erect Piers and Abutments: Build vertical supports (piers) and end supports (abutments) that will carry the arch.
Construct Centering: Erect temporary supports (falsework or centering) to hold the arch during construction.
Install Reinforcement: Place steel reinforcement within the substructure components.
Pour Concrete: Cast concrete for the piers and abutments.
Superstructure Construction (Arch)
Build the Arch: Construct the arch structure, either by casting concrete in place or by assembling precast arch segments.
Reinforce the Arch: Install steel reinforcement within the arch structure.
Secure the Arch: Ensure the arch is properly connected to the substructure and is stable.
Remove Centering: Carefully dismantle the temporary centering structure after the arch has gained sufficient strength.
Infill and Spandrels: Fill the space between the arch and the deck with infill material and build spandrel walls.
Deck Construction
Install Bearings: Place bearings on top of the arch or substructure to allow for expansion and contraction.
Build the Deck: Construct the bridge deck (roadway) on top of the bearings.
Install Expansion Joints: Install expansion joints to accommodate movement of the deck.
Install Wearing Surface: Apply the final wearing surface (e.g., asphalt) to the deck.
Finishing and Quality Control
Install Railings and Barriers: Add safety features like railings and barriers.
Conduct Inspections: Perform thorough inspections to ensure quality and safety.
Final Cleanup: Clean up the construction site and remove any remaining debris.
Opening and Maintenance
Open to Traffic: Officially open the bridge for public use.
Implement Maintenance Plan: Develop a schedule for regular inspections and maintenance to ensure the bridge’s long-term performance.
