Comply with OSHA 29 CFR 1910.23 – Guarding floor and wall openings and ANSI A1264.1, Safety Requirements for Workplace Floor and Wall Openings, Stairs, and Railing Systems. Follow local building codes, latest adopted edition.

1.2 DELEGATED DESIGN

Engage a Registered Structural Engineer to design the complete guardrail system (posts, rails, infill, brackets, and fascia mounted anchorage to the supporting deck structure) including connections and fasteners. Submit sealed calculations and shop drawings demonstrating compliance with the 2021 IBC Code.

1.3 PERFORMANCE / LOADING REQUIREMENTS

Handrails and Guardrails: Comply with loads in accordance with IBC 2021 and ASCE 7-22. Handrails: 200 pounds applied in any direction at any point along the handrail.

Guard Height: 42 inch minimum for nonresidential structures (per IBC) Drawings show 43” for safety factor. ADA Compliance: Handrail gripping surface shall comply with ADA accessibility guidelines. Opening / Climb Ability: No opening shall allow passage of a 4-inch sphere. Materials / Finish / Durability: Powder-coating to meet AAMA 2604.

1.4 SUBMITTALS

Submit shop drawings for fabrication and installation of handrails to include plans, elevations, sections, details at posts, corners, terminations, bracket plate geometry, fasteners, interface with deck fascia, outline of backing/ blocking requirements and any necessary accessory items. Sealed Structural Calculations: Demonstrate that handrail design meets all loading and geometric code requirements. Selection Samples: Two complete sets of color charts representing manufacturer’s full range of available colors and finishes. Load Tests: Submit test results from ASTM E935 conducted on the manufacturer’s supplied system indicating compliance with required structural loading. Samples: 12-inch length of top rail and picket with approved powder coat color and finish.
