Standard Specifications and Code of Practice for Road Bridges, Section VII: Foundations and Substructure
View at irc.nic.inWhat this code covers
Subsurface exploration requirements, design of open foundations, well foundations, pile foundations; piers, abutments, and retaining walls. Applies to bridges, viaducts, culverts, and grade-separated structures.
What this means on site
Essential for bridge foundation bidding and construction. Specifies foundation types, design methodologies, and construction practices. Critical for geotechnical design validation before work commences.

Standard Specifications and Code of Practice for Road Bridges, Section II: Loads and Load Combinations
Load classifications: Class 70R, Class A, Class AA. Dead loads, live loads, impact effects, wind loads, temperature effects, and seismic design guidelines for road bridges.
Guidelines for the Design of Small Bridges and Culverts
Design standards for small bridges (6–30m span) and culverts (up to 6m). Cross-drainage structures at nallas, irrigation channels, and seasonal streams on rural and state highway projects.
Guidelines for Seismic Design of Road Bridges
Seismic design provisions for road bridges in India: site classification, ground motion parameters, analysis methods (elastic response spectrum, time-history), ductile detailing, and isolation devices. Replaces IS:1893 guidance for bridge-specific seismic design.
