IS Code Finder for Civil Engineers
Find the right Indian Standard fast. Search by number or topic to see what each code covers, the values engineers look up most (cover, span/depth, loads, zone factors), and the matching calculator.
Editions shown are the latest we know of. BIS revises codes regularly, so always confirm the current edition on the BIS Standards portal before using a value for design. Key values are short summaries; the full clause in the code governs.
