**How to do check level on construction site?**

I will check the the level on construction site by spirit level (leveling staff), Auto level, and Levelling pipe.

**What is the accuracy of the dumpy level or minimum reading we can take?**

with the help of a dumpy level, we can take up 5mm accurate reading or minimum reading.

**How do you Calculate Unit Weight Steel Bars on-site?**

Unit Weight of Steel can be calculated by using the formula:

= D^2 / 162 Kg/m

**How do you calculate the weight of 10mm dia, And 12m long steel bars on-site?**

I can calculate by Multiplying the unit weight of 10 mm dia. Steel with Length,

Weight= Unit Weight x Lenght

Weight= (D^2 / 162) x 12

Weight= (10^2 / 162) x 12

Weight= 0.617 x 12

Weight= 7.40 Kg
