PART 3 — EXECUTION
3.01 PRE-INSTALLATION EXAMINATION
- Carefully observe and verify field conditions that substrates are ready for installation of architectural fiberglass balustrade system. Contractor shall verify on site dimensions with shop drawings and assume full responsibility for fitting the components to the structure.
- Verify that bearing surfaces are true and level.
- Verify that support framing has been constructed to allow accurate placement, alignment and connection of architectural fiberglass rails and newel post to structure.
- Report discrepancies between design dimensions and field dimensions, which could adversely affect balustrade system installation, to the Architect and/or Owner's Representative.
- Do not proceed with installation until discrepancies are corrected, or until installation requirements are modified and approved by the Architect and/or Owner's Representative.
- Beginning of installation means acceptance of existing conditions and fiberglass materials.
- Install architectural fiberglass balustrade system in accordance with manufacturer's instructions and approved shop drawings.
- Erect required connection blocking and framing plumb, square, and true to line and level to substrate. Recess blocking or notch blocking behind panel flanges per manufacturer's instructions. The installer shall supply connectors, blocking and framing approved by baluster system manufacturer.
- Space joints between rail sections and newel post according to shop drawings, not less than 1/8" and not greater than 3/8". Prepare joints by lightly sanding and filling joints with a continuous bead of specified sealant as work progresses to make a weather tight joint. Carefully monitor ambient temperatures at time of installation to prevent excessive expansion and contraction of balustrade system during sealant application.
- Do not field cut baluster rails or newel post where the finish cannot be field restored. Installer may repair small unnoticeable finish repairs with manufacturer's supplied colored gel-coat patching material.
- Countersink all exposed fasteners and repair with manufacturer's supplied colored gel-coat patching material. Repairs shall be made with care to be undetectable.
