METAL STAIRS AND HANDRAILS

[PART 1: GENERAL]{.underline}

1.1 SUMMARY

A. Section Includes: Furnishing and installing welded metal stairs and
handrails.

1.2 SUBMITTALS

A. General: Submittals shall be according to \[Section 01009 - General
Information and Requirements.\] \[and\] \[Section 01330 - Submittal
Procedures.\] \[and\] \[Section 01331 - Certificates.\]

B. Shop Drawings: Submit \[\_\_\_\] copies for approval indicating
thickness, type, grade, class of metal, and dimensions. Show
construction details, reinforcement, anchorage, and installation with
relation to stair construction. Drawings shall be prepared by and bear
the stamp of a registered structural engineer.

1.3 QUALITY ASSURANCE

A. Qualifications of Welders: Shall be according to AWS D1.1 using
procedures, materials, and equipment of the type required for the work.

1.4 PROJECT/SITE CONDITIONS

A. Environmental Conditions: Do not clean or paint surface when damp or
exposed to foggy or rainy weather, or when the material surface
temperature is below 45 degrees F or over 95 degrees F.

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS

A. Pipe: Individual members shall be 1-1/2 inch nominal diameter,
according to ASTM A 53, Type E or S, Grade B, Schedule 40 pipe with
welded joints ground smooth.

B. Fittings for Steel Pipe: Standard malleable iron fittings.

C. Steel and Iron: Standard mill finished structural steel shapes or bar
iron according to AISC Manual of Steel Construction and ASTM A 36.

D. Floor Plates: Shall be according to ASTM A 786 pattern 5. Unless
otherwise shown, steel plate shall be not less than 14 ga.

E. Anchors and Fasteners: Where exposed, shall be of the same material,
color, and finish as the metal to which applied.

2.2 FABRICATION

A. Shop Fabrication: Fabrication and assembly shall be done in the shop
to the greatest extent possible. Fabricate according to approved
drawings. Work shall be set to established lines and elevations and
securely fastened in place. Thickness of metal and details of assembly
and supports shall give angle strength and stiffness for the minimum
loads specified or indicated. Joints exposed to weather shall be formed
to exclude or drain moisture. Conceal fastenings where possible.

B. Finish: Metal, including accessories, shall receive a shop-applied
coating of zinc chromate according to ASTM D 478.

[PART 3: EXECUTION]{.underline}

3.1 EXAMINATION

A. Verification of Conditions: Verify measurements before fabrication.

3.2 PREPARATION

A. Surface Preparation: Clean metal work by power wire brushing or other
approved manual or mechanical means for removal of rust, loose paint,
scale, and deleterious substances. Wash cleaned surfaces which become
contaminated with rust, dirt, oil, grease or other foreign substances
with solvents until thoroughly clean. Cleaning steel to be imbedded in
concrete is not required.

B. Painting: After surface preparation, apply pretreatment and primer as
specified. Do not coat surfaces of items to be embedded in concrete.
Recoat damaged surfaces using surface preparation, treatment, primer,
and paint that was applied to adjacent surfaces upon. On surfaces that
will be concealed in finished construction or that will not be
accessible for finish painting, apply an additional prime coat to a
minimum dry film thickness of 0.1 mil. Tint the additional prime coat
with a small amount of tinting pigment. See also Section 09915 -
Exterior and Interior Painting.

3.3 ERECTION/INSTALLATION

A. General: Metalwork shall be formed to shape and size, with sharp
lines and angles and true curves. Provide welding and bracing of
adequate strength and durability, with tight, flush joints, dressed
smooth and clean. Shearing and punching shall leave clean, true lines
and surfaces. Weld permanent connections and finish smooth where exposed
after installation.

B. Welding: Perform welding, welding inspection, and corrective welding
according to AWS D1.1. Weld in a manner to prevent permanent distortion
of the connected parts. Weld continuously along the entire area of
contact except where tack welding is permitted. Do not tack weld exposed
connections. Grind smooth all welds that will be visible in the finished
installation.

C. Joints: Mill joints to a close fit where tight joints are required.
Corner joints shall be coped or mitered, well formed, and in true
alignment.

D. Handrails: Erected in a rigid manner, straight, plumb. and in
positions shown on drawings.

1\. Top surface shall be according to the following:

42 inches above horizontal surfaces

32 inches above stair nosings

32 inches above ramped surfaces

2\. Rails shall extend horizontally 12 inches beyond the top and bottom
of ramps for the handicapped, or as shown on the drawings, and return to
wall-mounted brackets. Wall-mounted stair handrails shall extend 12
inches at top of stair and continue slope past bottom riser of stair for
a distance equal to the tread dimension; then extend horizontally for 12
inches and return both ends to wall-mounted brackets. Stair-mounted
handrails shall continue slope for 12 inches and return to newel post.

3\. Rails shall be capable of resisting a force of 200 lbs applied at
any point, vertically downward or horizontally, to the top of the rail
as required by NFPA 101.

E. Anchorage: Provide anchorage for fastening work securely in place.
Sizes, kinds, and spacings of anchors not indicated or specified shall
be as necessary for the purpose, and approved by the Contracting
Officer. Provide inserts of suitable approved types where required for
support of anchorage of finish construction. Anchors and anchor bolts in
exterior walls shall be zinc-coated.

F. Fastenings: Do not use wood plugs in any material. Make exposed
fastenings of compatible material. Conceal fastenings where practicable.

G. Threaded Connections: Make bolted work up tight and nick the threads
or bush the stem to prevent loosening.

H. Anchors and Connecting Members: Provide in concrete or masonry as the
work progresses, to avoid unnecessary cutting and drilling.
