The document provides instructions for making reinforced concrete columns. It lists the necessary materials as cement, sand, gravel, water, wooden plates, iron bars, and binding tar. Tools include a khore, palm, right angle, hammer, trowels, hacksaw, and pliers. The procedure involves making a 3000mm by 600mm by 150mm square frame with iron rods welded at intervals, pouring concrete into wooden molds, and curing the columns under wet gunny bags for at least 2 hours. Precautions include ensuring the iron bars extend beyond the column height and connecting the square frame from the outside.

12. Precautions :
 1. Tor iron bar should be 10-15 cm. long than

 2. Square frame should be joined at an interval of
25mm. (1”)
 3. Square frame must be rectangular and must
be connected from outside of all 4 rod.
 4. Make all concrete required in one batch.
 5. Put some concrete in mould (wooden plates
