Construction, operations and maintenance
==Construction, operations and maintenance==
A gabion structure can be built without any mechanical equipment and works can start immediately because the initial stages of excavation and laying of foundations are minimal and can be carried out by hand. Likewise, for underwater structures, the first layer of gabions can be laid in water or in mud without the need for draining the site. Upon completion, a gabion structure will take its full load immediately without the waiting periods - of up to one month - normally associated with concrete structures. Furthermore, it is relatively easy to obtain good construction quality because of the simplicity of the two construction materials, i.e. the gabion baskets and the stones or rock fragments.
 
# Lay out a length of concrete reinforcement wire at the gabion site. If building on a bank, make sure the wire extends all the way up the edges of the bank.
# Trim the concrete reinforcement wire as needed with wire cutters. The size and shape of this wire will determine the size and shape of your gabion. Make the layout of wire about twice the size of the gabion you intend to build, as you will eventually fold the wire over itself.
# Line the entirety of the concentrate reinforcement wire with a layer of chicken wire.
# Load a wheelbarrow full of large, medium-size and small rocks. Collect enough rocks to spread over the length of your gabion.
# Fill the top part of the concrete reinforcement wire -- the part nearest the area you wish to protect from erosion -- with rocks by shoveling them from the barrow. Create an even layer of rocks about 6 inches to 1 foot high and 2-to-3 feet wide across the length of the wire.
# Spread a layer of sand or soil over the rocks, allowing it to fill the crevices between them. Pat down the soil with a shovel.
# Enclose the rocks by folding the remaining length of concrete reinforcement wire over them.
# Fasten the concrete reinforcement wire that is covering the rocks to the wire under the rocks by tying the layers together with lengths of thick wire cut from wire coat hangers.
