Engineering Bridges That Stand the Test of Time

Bridges and overpasses are among the most demanding and consequential structures in any road network. They must withstand dynamic traffic loads, flood scour, seismic forces, and decades of service with minimal maintenance. HRP Infra brings rigorous multi-discipline engineering to every bridge project — integrating hydraulic analysis, geotechnical investigation, and structural design to deliver safe, durable, and cost-effective crossings.

From minor culverts to major river bridges and urban flyovers, our team manages the complete project lifecycle: site investigation, hydraulic and hydrological studies, structural analysis, detailed drawing production, DPR preparation, and construction supervision.

  • Major & Minor Bridge Design (RCC/PSC)
  • Flyovers, ROBs & Grade Separators
  • Hydraulic & Scour Analysis
  • Foundation & Sub-structure Design
  • Bridge Inspection & Load Assessment

Structure Types

Bridge & Overpass Categories We Engineer

Major River Bridges
Long-span RCC or PSC bridges over rivers and major water bodies with full hydraulic and scour analysis.
Flyovers & Grade Separators
Urban and peri-urban grade separation structures to eliminate traffic conflict at busy intersections.
Railway Over/Under Bridges
ROBs and RUBs coordinated with Indian Railways and RDSO loading standards for road-rail crossings.
Minor Bridges & Culverts
Box culverts, pipe culverts, slab bridges, and causeways for drainage crossings on rural and urban roads.

What We Deliver

Bridge Engineering Service Offerings

Hydraulic & Hydrological Analysis

Flood frequency analysis, design discharge computation (Rational, Unit Hydrograph methods), afflux calculation, and scour depth estimation per IRC:SP:13.

Geotechnical Investigation

Borehole drilling, SPT/SCPT testing, soil classification, and bearing capacity analysis for optimal foundation selection — pile, well, or open foundation.

Structural Analysis & Design

IRC 6/78/112-compliant superstructure and substructure design using STAAD.Pro, SAP2000, and MIDAS — covering RCC, PSC, and steel composite options.

Detailed Drawings & DPR

Complete drawing package — general arrangement, reinforcement details, bar bending schedules, and DPR with quantity estimates for government and tender submissions.

Construction Supervision

Resident structural engineer services for pile installation, formwork, concrete batching, pre-stressing, and deck finishing with test certificates and pour records.

Inspection & Load Rating

Condition assessment of existing bridges per IRC:SP:35, load rating calculations, and rehabilitation recommendations including deck replacement and strengthening.

Design Standards

Codes & Standards We Follow

  • IRC 6
    Standard Specifications for Road Bridges — Loads & Load Combinations The primary loading code governing vehicular, pedestrian, seismic, and wind loads on all road bridges.
  • IRC 78
    Standard Specifications for Road Bridges — Foundations & Substructure Foundation design requirements for wells, piles, and open footings under bridge substructures.
  • IRC 112
    Code of Practice for Concrete Road Bridges Limit state design methodology for RCC and PSC superstructures, replacing the older IRC:21.
  • IRC SP:13
    Guidelines for Design of Small Bridges & Culverts Hydraulic design and structural sizing for minor crossing structures on rural and urban roads.
  • IS 1893
    Seismic Design Provisions Zone-specific seismic force computation and detailing requirements for bridges in seismically active regions.
