F.	PCI Certification: An extensive audit program that evaluates a manufacturer's business practices, process elements, equipment, maintenance practices and quality control capabilities. Certified coaters can show, through demonstrated audit performance measurement, that they have the capabilities to correctly clean, coat and cure products to meet manufacturer's recommendations. Certification is not a determination of the quality of the powder coated product that is produced. It strictly certifies that the coater has the capabilities and competencies to produce a high-quality powder coated product.

B.	Shop assemble railings to greatest extent possible to minimize field splicing and assembly. Disassemble units only as necessary for shipping and handling limitations.
1.	Clearly mark units for reassembly and coordinated installation.
2.	Use connections that maintain structural value of joined pieces.
C.	Cut, drill, and punch metals cleanly and accurately.
1.	Remove burrs and ease edges to a radius of approximately 1/32 inch (0.8 mm) unless otherwise indicated.
2.	Remove sharp or rough areas on exposed surfaces.
D.	Form work true to line and level with accurate angles and surfaces.
E.	Fabricate connections that will be exposed to weather in a manner to exclude water.
1.	Provide weep holes where water may accumulate.
2.	Locate weep holes in inconspicuous locations.
F.	Cut, reinforce, drill, and tap as indicated to receive finish hardware, screws, and similar items.
G.	Connections: Fabricate railings with mechanical connections unless otherwise indicated.
2.6	GENERAL FINISH REQUIREMENTS
A.	Comply with NAAMM's "Metal Finishes Manual for Architectural and Metal Products" recommendations for applying and designating finishes.
B.	Protect mechanical finishes on exposed surfaces from damage by applying a strippable, temporary protective covering before shipment.
C.	Provide exposed fasteners with finish matching appearance, including color and texture, of railings.
PART 3    EXECUTION
3.1	EXAMINATION
A.	Examine plaster and gypsum board assemblies, where reinforced to receive anchors, to verify that locations of concealed reinforcements have been clearly marked for Installer. Locate reinforcements and mark locations if not already done.
3.2	INSTALLATION, GENERAL
A.	Perform cutting, drilling, and fitting required for installing railings.
1.	Fit exposed connections together to form tight, hairline joints.
2.	Install railings level, plumb, square, true to line; without distortion, warp, or rack.
3.	Set railings accurately in location, alignment, and elevation; measured from established lines and levels.
4.	Set posts plumb within a tolerance of 1/16 inch in 3 feet (2 mm in 1 m).
5.	Align rails so variations from level for horizontal members and variations from parallel with rake of steps and ramps for sloping members do not exceed 1/4 inch in 12 feet (6 mm in 3 m).
B.	Control of Corrosion: Prevent galvanic action and other forms of corrosion by insulating metals and other materials from direct contact with incompatible materials.
1.	Coat concealed surfaces of aluminum that will be in contact with grout, concrete, masonry, wood, or dissimilar metals, with a heavy coat of bituminous paint.
C.	Adjust railings before anchoring to ensure matching alignment at abutting joints.
D.	Fastening to In-Place Construction: Use anchorage devices and fasteners where necessary for securing railings and for properly transferring loads to in-place construction.
3.3	RAILING CONNECTIONS
A.	Nonwelded Connections: Use mechanical or adhesive joints for permanently connecting railing components. Use wood blocks and padding to prevent damage to railing members and fittings. Seal recessed holes of exposed locking screws, using plastic cement filler colored to match finish of railings.
B.	Expansion Joints: Install expansion joints at locations indicated but not farther apart than required to accommodate thermal movement. Provide slip-joint internal sleeve, extending 2 inches (50 mm) beyond joint on either side; fasten internal sleeve securely to one side; and locate joint within 6 inches (150 mm) of post.
3.4	ANCHORING POSTS
A.	Anchor posts to metal or concrete surfaces with flanges, angle type, or floor type as required by conditions, connected to posts and to metal supporting members as follows:
1.	For aluminum railings, attach posts as indicated, using fittings designed and engineered for this purpose.
3.5	ATTACHING RAILINGS
A.	Anchor railing ends to concrete and masonry with bracket connectors to railing ends and anchored to wall construction with anchors and bolts.
B.	Anchor railing ends to metal surfaces with bracket connectors bolted to metal surfaces.
C.	Attach handrails to walls with wall brackets, except where end flanges are used.
1.	Bracket Clearance: Inside handrail face to finished wall surface: 1-1/2 inch (38 mm).
2.	Bracket Clearance: Inside handrail face to finished wall surface: ___ inch (___ mm).
3.	Bracket Type: Flange tapped for concealed anchorage to threaded hanger bolt.
4.	Bracket Type: Predrilled holes for exposed bolt anchorage.
5.	Locate brackets as indicated or, if not indicated, at spacing required to support structural loads.
D.	Secure wall brackets and railing end flanges to building construction as follows:
1.	For Concrete and Solid Masonry Anchorage: Use drilled-in expansion shields and hanger or lag bolts.
2.	Hollow Masonry Anchorage: Use toggle bolts.
3.	Wood Stud Partitions: Hanger or lag bolts set into studs or wood backing between studs. Coordinate with carpentry work to locate backing members.
4.	Steel Framed Partitions:
a.	Hanger or lag bolts set into fire-retardant-treated wood backing between studs. Coordinate with stud installation to locate backing members.
b.	Fasten brackets directly to steel framing or concealed steel reinforcements using self-tapping screws of size and type required to support structural loads.
c.	Fasten brackets with toggle bolts installed through flanges of steel framing or through concealed steel reinforcements.
3.6	REPAIR
A.	Touchup Painting: Immediately after erection, clean bolted connections, and abraded areas of exposed areas with the same material used for shop painting to comply with SSPC-PA 1 for touching up shop-painted surfaces.
1.	Apply by brush or spray to provide a minimum 2.0-mil (0.05-mm) dry film thickness.
3.7	FIELD QUALITY CONTROL
A.	Testing Agency: Owner will engage a qualified testing agency to perform tests and inspections and to prepare test reports.
1.	Payment for Services: Will be made by Owner.
2.	Payment for Services: From the testing and inspecting allowance.
3.	Payment for Services: As authorized by Change Orders.
B.	Extent and Testing Methodology: Testing agency will randomly select completed railing assemblies for testing that are representative of different railing designs and conditions in the completed Work. Test railings in accordance with ASTM E894 and ASTM E935 for compliance with performance requirements.
C.	Remove and replace railings where test results indicate that they do not comply with specified requirements unless they can be repaired in a manner satisfactory to Architect and comply with specified requirements.
D.	Perform additional testing and inspecting, at Contractor's expense, to determine compliance of replaced or additional work with specified requirements.
3.8	CLEANING
A.	Clean aluminum by washing thoroughly with clean water and soap, rinsing with clean water, and wiping dry. Do not use chemical cleaners.
B.	Clean Stainless Steel cables and coat with Boeshield T9 Protectant, or approved protectant, as recommended by manufacturer.
3.9	PROTECTION
A.	Protect finishes of railings from damage during construction period with temporary protective coverings approved by railing manufacturer. Remove protective coverings at time of Substantial Completion.
B.	Restore finishes damaged during installation and construction period, so no evidence remains of correction work. Return items that cannot be refinished in the field to the shop; make required alterations and refinish entire unit or provide new units.
