3 EXECUTION

3.1 EXAMINATION

32 31 00-15

3.1.1 Do not begin installation until final grades and contours have been properly prepared.

3.1.2 Examine conditions under which fencing and gates are to be installed. Notify Contractor of unsatisfactory conditions. Do not proceed with work until conditions are satisfactory to the installer.

3.2 PREPARATION

3.2.1 Coordinate fence installation with work of other sections.

3.3 INSTALLATION

3.3.1 Install fence and gates in accordance with manufacturer's instructions and approved installation drawings. Install fencing to withstand wind load as specified.

3.3.2 Handle fence components to protect finish coating from any scuffs, abrasion or other damage during installation. Excessive damage to factory applied coatings will be cause for rejection.

3.3.3 Space posts at dimensions indicated in the installation drawings. Attach fence rails to posts using galvanized, stainless steel or zinc plated panel hanger brackets supplied by manufacturer. Field welding of panels to posts is unacceptable as it will cause significant damage to the galvanizing and powder coat protective finishes.

3.3.4 Concrete Footings: Place concrete around posts and vibrate or tamp for consolidation. Verify that posts are set plumb, aligned, and at correct height and spacing, and stabilized in position during placement and finishing operations until concrete is sufficiently cured. Protect portion of posts above ground from concrete splatter.

3.3.5 Install gates level, plumb, and secure for full opening without interference. Attach hardware using tamper-resistant or concealed means. Install ground-set items in concrete for anchorage. Adjust gate to operate smoothly, easily, and quietly throughout entire operational range. Confirm that latches and locks engage accurately and securely without forcing or binding.

3.3.6 Avoid unnecessary cutting, drilling and welding of pre-finished fence components. If necessary to cut drill, weld or otherwise modify product due to field conditions, repair factory finish.3.3.6.1 Touch-up any necessary areas by lightly sanding; clean area thoroughly, apply a

zinc-rich cold galvanizing primer followed by a high quality acrylic lacquer paint to match finish. (Touch-up paint available from manufacturer) Field applied touch-up does not match the performance of factory applied finishes and shall be limited in use. Field applied paint is not warrantable.

3.4 PROTECTION

3.4.1 Installer shall remove packing materials and unused product and level uneven areas due to excavations created by fence installations.

3.4.2 Protect installed products until completion of project.

3.4.3 Touch-up, repair or replace damaged products before Substantial Completion.
