CPWD's 11 correction slips, up to 4 August 2026, are in RateAnalyser. A slip can add a new analysis, change an old one, or give a basic rate code to a second material.
What you will see
- Search for an item from a slip and open it like any other. Its page shows no page of the book, because a slip prints it and not a page of the volumes. The line at the bottom names the Delhi Analysis of Rates 2023 and gives no page.
- An item that a slip changed also shows no page, because the page of the book still prints the old figures.
- In Basic rates, when a slip gives a code to a second material, the list shows both. The book's own comes first, and the one from the slip has Correction slip and its number beside it.
Things to know
- An item from a slip works like every other item. You can open it, follow its lines and change its rates.
- A change to the basic rate of the book's material does not move a line that uses the slip's material, because they are two different rates. The Basic rates list
- For a few items from slip 2, like 22.27A.2 and 22.28.1, the rate is CPWD's and the working printed in the slip does not add up. The page then shows the rate first, with our working beside it. When the book does not add up
- Check the published book and CPWD's slips before you use a rate in a bill.
