- To draw the engineering drawing for water tank, toilets and septic tank. To estimate the cost of materials.
- To mark the plot.
Then, we decided to construct water tank having capacity of 5000 liters which will be of 10″*5″*4″ and we also decided to construct toilets of 3″*4″ dimension. Before starting the construction we prepare engineering drawing for water tank, toilets and septic tank.
we list out the materials which are used in construction i.e bricks, dust, gravels, etc. and estimate the material cost.
Then, we mark the plot for construction. Excavation is carried out for the construction wall foundation. Excavation should be carried as per the the drawings defined lengths and width.
