Fence construction, planning,maintenance, demolitionand site clean up and preparation
Preparations for fencing includeEstablish the type of fence requiredSheepCattle Horses DeerIs the positioning of the fence going to involve high traffic area and multi type stocking?
Planning involvesChoosing the best style for the job.Post spacings?Line post type?Strainer and Stay type?Gauge of wire and number of wires?Length of fence?
Number of gate ways?Type of gates?Number of strains required?Extras such as standouts, insulators etc?Can you re use materials from an existing fence, if so how much?Planning involves
Draw up your plan to show the style of fence proposed for contractors to quote on or for employees to clearly understand the construction.Planning involvesStandard fencing pattern proposed for paddock subdivision and boundary.

Planning (Cont)Type of labour required for construction?(Self, employees, contractor, labour exchange)Type of equipment required for construction?Total Cost = ?Economics or value for money
Planning considerationsIs the area fire prone?Does the fence need to be portable?What are the likely stocking rates?Does the type of livestock requiring to be fenced need heavier construction materials for animals such as bulls?Do you have a range of livestock types?
Does the type of ground require special construction techniques, equipment, materials: example hills, gullies, water ways, soil types, swamps and vegetation etc?Do you require the fence to last?Does the fence need to keep out various types of vermin? Planning considerations
Length of strain Fire resistance Stock typeElectrical conductivity Flexibility or stretch requirement Planning considerationsThe type and gauge of wire to be used is dependant on
Workability preferences Economical considerationsCompatibility to the type of post materialsEnvironmental implications such as salt etc. Does the fence require a horse sighter wire such as BaycoPlanning considerations
Maintenance issuesDoes the fence have trees along it?High stocking ratesFire resistanceHigh traffic areasLongevityMaterialsRust

Good fence construction practices includeWear PPE gloves, eye protection from U.V and wire, broad brimmed hat, steel capped bootsDo not drop small pieces of wire (livestock die from swallowing)Do not drop fence staplesFill in all holesDo not leave unnecessary mess such as lengths of wire lying around
Pick up all the old postsDo not leave un rammed dirt around new posts where stock can scratch it outAlways drive wooden posts small end firstPut a pilot hole large enough for the size of post being drivenAlways use a cap with wads in when driving pre stressed concrete postsAlways take particular care when using PTO post hole diggers Good fence construction practices include
Always keep hands away from the top of posts when using a post driverTake particular care when operating tractors with post drivers in hilly areas (Always put the dolly down before driving)If barbed wire is being strained Keep away and do not put hands near without gloves. Remember barbed wire can cause similar injuries to a chain saw especially high tensile barbed wireGood fence construction practices include
Always ram the dirt around the bottom and top of a post as firmly as possible.Make sure that line post positioning is as close as possible to alignment with the strainer posts (Remember Install end strainers first with tops of strainer at least 25mm above tops of line posts).Make sure to keep base of line posts as close as possible to alignment (The tops of posts can be moved quite a bit to bring them in line without looking to bad). Good fence construction practices include
Strainer and stay assembly for wet area
