Construction area, outside Dhaka, 1986.
This area, several square miles, provides all the raw materials to feed Dhaka's construction appetite. Soil is brought in on boats and made into bricks in giant kilns. These bricks in turn are taken by boat into other areas where they are sold or crushed to use in construction. Since the soil of Bangladesh is almost devoid of stones, crushed bricks are used instead of rocks for making concrete.
