Transcribed from Tamil Nadu TWAD Board — Standard Schedule of Rates 2023-24, effective 23 January 2024. For reference only. Departments amend rates through correction slips between editions, so verify against the official source before pricing a bid. Items we could not transcribe unambiguously have been left out.

How to use the Tamil Nadu Schedule of Rates

The water works schedule of rates sets the department's accepted rate for each item of work, and estimates for Tamil Nadu government projects are built by mapping a project's Bill of Quantities to these items. Rates here run from ₹1.07 per rm to ₹38,62,111.00 each, spanning 11 chapters from earthwork through to finishing trades.

Three things routinely go wrong. Estimators price against a superseded edition, because correction slips are published separately from the main schedule. They pick a nearly-similar item code rather than the exact one, which can pass an internal review and still be rejected by the department. And they miss that a rate is quoted for a different unit than the BOQ uses. A rm rate applied to a nos quantity is a large error that looks reasonable on a spreadsheet.
