PART 1 – GENERAL
1.1 DESCRIPTION
.1 General Requirements are part of this specification and shall apply as if repeated here.
.2 Work includes:
.1 Interior Decorative Metal Guards and Railings
.2 Exterior Decorative Metal Guards and Railings
.3 Related work not included:
.1 Substrates
1.2 COORDINATION
.1 Coordinate installation of anchorages for decorative metal railings. Furnish setting drawings, templates, and directions for installing anchorages, including sleeves, concrete inserts, anchor bolts, and items with integral anchors, that are to be embedded in concrete or masonry. Deliver items to Project site in time for installation.
.2 Coordinate installation of decorative formed metal with adjacent construction to ensure that wall assemblies, flashings, trim, and joint sealants, are protected against damage from the effects of weather, age, corrosion, and other causes of deterioration.
1.3 DESIGN REQUIREMENTS
.1 Panel removal: System shall be non-progressive, allowing removal of any individual panel without necessitating removal of adjacent work.
.2 Structural movement: Accommodate movement of supporting structural framing and without causing bowing, buckling, delamination, oil canning, excessive stress on fasteners, or any other detrimental effects.
.3 Thermal Movements: Allow for thermal movements from ambient and surface temperature changes by preventing buckling, opening of joints, overstressing of components, failure of connections, and other detrimental effects. Base calculations on surface temperatures of materials due to both solar heat gain and nighttime sky heat loss.
.1 Temperature Change (Range): 120 deg F, ambient; 180 deg F, material surfaces
.4 Maximum deviation from vertical and horizontal alignment of erected railings: 0.25" in 20' 0"
.5 Maximum deviation from panel flatness shall be 0.10" in 60" panel in any direction for assembled units (non-accumulative).
1.4 SAMPLES
.1 Submit samples in accordance with Division 1 Section, Submittals.
.2 Submit duplicate, minimum 3-inch by 5-inch samples of each color selected.
1.5 SHOP DRAWINGS
.1 Submit shop drawings in accordance with Division 1 Section, Submittals
.2 Indicate elevations, profiles, dimensions and thickness of railings.
.3 Indicate location and detail of joints including joints necessary to accommodate thermal movement.
.4 Indicate attachment clips, joint extrusion system and installation details.
.5 Show fastening and anchoring details.
.6 Coordination Drawings: For decorative formed metal elements that house items specified in other Sections. Show dimensions of housed items, including locations of housing penetrations and attachments, and necessary clearances
.7 Drawings for railing and guard infill panels shall be signed and sealed by a Professional Engineer licensed in the jurisdiction where the Project occurs, attesting to the ability of the metal panel's assembly to withstand the specified loads.
.8 Railings shall be identified on the shop drawings, using the Specified Identification and as to building location to facilitate panel removal and replacement.
1.6 LEED SUBMITTALS:

1.8 DESIGN REQUIREMENTS
.1 IBC 2015 Edition, Section 1607.8: Handrail and guard assemblies and attachments shall withstand a linear load of 50 pounds per linear foot in accordance with Section 4.5.1 of ASCE 7.
.2 Handrail and guard assemblies and attachments shall withstand a concentrated load of 200 pounds applied horizontally or vertically down at any point on the top rail.
.3 Infill area of guard rail system shall be capable of withstanding a horizontal concentrated load of 50 pounds applied to one square foot at any point in the system and to transfer this load through the supports to the structure. Load not to act concurrently with loads on top rail of system in determining stress on guardrail.
1.9 PRODUCT DELIVERY, HANDLING AND STORAGE
.1 Protect finish and edges using a plastic film adhered to panel in accordance with panel manufacturer’s recommendations.
.2 Store components and materials in accordance with panel manufacturer’s recommendations.
