PART III  EXECUTION

 3.01      GRADING

                   The ground shall be graded to an easy even slope all along the length of the area where the fence is to be                    installed.

3.02       FENCE INSTALLATION

A.      Install the fence along the specified area. The fence shall be installed a distance of  minimum of 30 mm

         (1-1/5 in.) and maximun of 50 mm (2 in.) above the ground surface. Post hole shall be a minimum of 200 mm

         (8 in.) in diameter and 1070 mm (42 in.) in depth.

B.      Profile posts installation : Insert the first post vertically in quick-set concrete at its proper height. The post needs           to be a  minimum of 460 mm (18 in.) in concrete. Once the concrete is set the mesh section is then hooked on the           post and held in place with 2 tensioning devices. The second post, placed in the hole pre-filled with concrete is           then hooked onto the other side of the mesh sections. The end section is fixed with two tensioning devices and           held until the concrete sets. The procedure continues until completed. Post spacing are 2416 mm (95-1/8 in.) c/c           of the profile post

          C.       Square posts installation 2 in. or 3 in.: Insert all the posts vertically at its proper height in concrete. Once the                      concrete is set, the mesh sections are installed with the attachment kits 2 in. or 3 in. at each folds. Post spacing                      are for 2 in. post  2464 mm (97 in.) c/c with a adjustment of ± 32 mm (1-1/4 in.) and for the 3 in. post 2490 mm                      (98 in.) c/c of the post with a adjustment of ± 32 mm (1-1/4 in.).

          D.    When any   posts or wire mesh section is field cut or trimmed for fit, a zinc rich primer must be applied to                     the exposed  ends, and after an   Touch-up paint matching the proper color shall be used.

E.        The mesh shall be installed according to owners instructions with the following options

                                   1) Spikes up or down

                                            2) Folds facing inside or outside.     

3.03            GATE INSTALLATION :

A.       Install gate posts in accordance with manufacturer's instructions. 

          B. Concrete Set Gate Posts: Drill holes in firm, undisturbed or compacted soil. Holes shall have a diameter 4 times               greater than outside dimension of post, and depths approximately 152mm (6 in.) deeper than frost level.               Excavate deeper as required for adequate support in soft and loose soils, and for posts with heavy lateral loads.               Set post bottom 36 inches (914mm) below surface when in firm, undisturbed soil. Place concrete around posts in               a continuous pour, tamp for consolidation. Trowel finish around post and slope to direct water away from posts.               Check each post for vertical and top alignment, and maintain in position during placement and finishing               operations.

          C. Install gates perfectly horizontal and leveled (at junction).

          D.      Attach hardware by means which will prevent unauthorized removal.

          E.       Adjust hardware for smooth operation.
