    4.2.2. Insert and Embedded Metal

    All item embedded in concrete shall be of type required for the intended task

    4.2.3. Weight and Dimension of Precast Concrete

    Weight and dimension of Precast concrete will shown on detail drawing

    4.2.4. Precast Concrete Panel

    Concrete posts are typically slotted for standard panelling, pre-drilled for wires, or fitted with brackets to

    carry non-standard or heavy panels. The steel posts are typically used with security or anti-vandal fencing.

    Most of the readily available fencing of this type is described and sold in imperial units, which will be

    used here for clarity.

    The posts required should be 450-600mm (1'6" - 2'0") longer than the height required. So, for a 1.8m

    (6') high fence, a 2.36m (7'9") post is required.

    Precast it is not required

    we follow with the existing fence.

    Set up a taut string line to guide the run of the fence and final alignment. Excavate the first post hole

    approximately 300x300mm (12"x12") in plan and at least as deep as shown in the table above for the

    size of post being installed. It's common practice to dig the post hole around 50mm (2") deeper than

    the required minimum, to allow for a modest bed of concrete to be used to adjust the height of the

    post and so aid final profiling.

    Use a pencil or similar to mark where Ground Level (GL) would be on the post when it is at the correct

    height. Place half a spade of concrete into hole (if required) and lower the post into the hole. Check

    that the pencil mark tallies with required ground level, adjusting the post by twisting it into bedding

    concrete or adding extra concrete bed, as required. Once the height is correct, align the post vertically

    by checking on two perpendicular faces for plumb, and jam the post in place with a few half-bricks,

    broken concrete flags or other hardcore, prior to concreting.

    GCMT-13-CIV-SPC-005 C Job. No : 31-12008PO002

    Use a dry mix concrete and sprinkle this in amongst the hardcore. Water it in with a can or a hose, anduse a long bar or stick to poke the wetted concrete down amongst the hardcore, filling all of the voids.

    Add more dry mix and water in as required. The top of the concrete/hardcore should be kept a couple

    of inches below ground level.

    Once the post is in position, place a base panel into the slot and along the required run line to ascertain

    distance and position of the next hole. Put the base panel to one side whilst the next hole is dug, then

    re-position and level it prior to positioning the next post. Make sure the new post is positioned fairly

    tight against the base panel, and check it for height and plumb before concreting-in as before and

    moving on to the next section.

    Leave off fitting the timber panels until all the posts are in and secure. It may be worth 'spragging' the

    posts with temporary supporting timbers while the concrete hardens.In windy conditions, it's best to

    allow concrete to set overnight before fitting panels, which dramatically increases the fence's wind-

    resistance.

    4.3.1. General

    Fencing shall conform to the details and shall use BRC fencing type fabricated and has license of ISO

    9001:2000.

    4.3.2. Material

    Material of fencing should be high quality low carbon steel wire. BRC fencing should be good corrosion

    resistance, anti-aging, nice appearance, easy and quick installation.4.3.3. Type and Process

    Fencing type is welded fence. Fencing should be galvanized to prevent rusting and corrosion.

    4.3.4. Colours

    Fencing could be any colour but should be colourful

    4.3.5. Fence Packaging

    In packaging process, fence should be protected and covered by appropriate material to ensure the safety

    and minimize the damage. Or cover by plastic film and wooded panel.

    4.3.7. Detail Installation

    Installation of fencing shall be in accordance with the requirements of ASTM F567.

    Suggested procedure is first planted buffer iron pipe or permanently cemented in the fence line.Usually it takes 2 people to put up, one worker and one assistant.

    Fences can be glued to a metal pipe with one of the following ways, namely:

    4.1. 1. Using the U bolts and clamps to clamp the fence at the top and bottom, the U bolts is

    clamped into iron triangle.

    4.2.2. Jump in welding to steel pipe (with electric welding). The weld connecting the three points

    which are usually the middle and bottom. This method is easier and shorter than the first way.

    Notes before installing, make a rope connecting the pole to measure the alignment of iron pipe

    fence. And vertical alignment gauge fence, both of these processes require one assistant. When

    installed alone, then you need a fence before being installed rafters shaped angled triangle by 4

    seeds to withstand the fence when installed.

    Dont forget to check the straightness of fences after all been done.

    7.0. PREPARATION

    Provide a reasonably smooth profile at the fence line. The bottom of the fence shall not be more than 50

    mm above the finished ground line. Where the fence crosses features such as streams and drainage

    ditches and it is impractical to conform with the fence to the ground contour, the fence shall span the

    depression, unless otherwise shown on the plans. Close the space below the bottom of the fence with

    extra fence fabric or barbed wire.

    8.0. FENCE INSTALLATION

    Installation of fencing shall be in accordance with the requirements of ASTM F567.

    Fencing shall be erected in straight lines between angle points by skilled mechanics experienced in

    this type of construction and in accordance with the manufacturer's printed recommendations asapproved and with these specifications. Posts shall be spaced not more than 3 meters on centers and

    in true lines. Posts shall be set plumb and rigid after installation. Centerline of fence braces shall be

    12 inches below the top of the fabric. The top surface shall have a crown watershed finish. After

    concrete has set, accessories shall be installed. Chain link fabric shall be fastened to end posts with

    stretcher bars and clamps and to line posts and top rail with wire or bands at approximately 14-inch

    centers and 24-inch centers, respectively. Gate posts shall be braced diagonally to adjacent line posts

    to ensure stability.

    Changes in direction of the fence line where the horizontal angle is 15 degrees or more shall be

    considered as corners and corner posts shall be installed. Changes in the grade where the vertical

    angle exceeds five percent shall have slope posts installed at the point of change.

    Between posts, the chain link fabric shall be fastened to a top and bottom tension wire with 4 mm

    diameter.

    Tie wire shall not be lighter than nine-gauge galvanized steel wire. The use of approved galvanized

    steel bands will be permitted in lieu of tie wires for fastening the chain-like fabric to the posts and

    gate frames.

    For precast concrete fence, the posts are positioned and erected by site. The pier size, depth and

    reinforcement are constructed as specified on engineering drawing. After the post are accurately

    spaced, plumbed and leveled, they are braced until the pier concrete has obtained its initial strength.

    With the post erected, the panels are manually slid into place. Where posts spacing must be less than

    1.5 meter, the panel are saw cut to the length as required fit. Post caps and panel caps are bonded

    into place by applying a silicone based adhesive between cap and fence component.

    Gates shall be hung and all hardware shall be adjusted so that gates operate satisfactorily from OPEN

    or CLOSED position. Gate shall be installed plumb, level and secure for full opening without

    interference. Install ground set items in concrete for anchorage as recommended by the fence

    manufacturer. Adjust hardware for smooth operation and lubricate. Sliding gate shall operate

    smoothly and easily under minimum pressure.

    Place concrete around posts in a continuous pour. Check each post for plumb and vertical and top

    alignment, and hold in position during placement and finishing operations.
