2.3 MATERIALS

A. Metal Surfaces, General: Provide materials with smooth surfaces, without seam marks, roller marks, rolled trade names, stains, discolorations, or blemishes.

B. Brackets, Flanges, and Anchors: Same metal and finish as supported item unless otherwise indicated.

C. Aluminum Structural Members: 6061-T6 Aluminum

D. Aluminum Channels: Aluminum Association Standard Channels (AAS)

E. Aluminum I-Beams: Aluminum Association Standard I-Beams (AAS)

F. Aluminum Plate: 6061-T6

G. Aluminum Grating: 1.5” I-Bar Grating, 6063-T6 Aluminum

H. Rock Bolts: Spin-Lock Type Rock Bolt

2.4 MISCELLANEOUS MATERIALS

A. Fasteners: Select fasteners of the type, grade, and class required to produce connections capable of withstanding design loadings.

1. For aluminum, provide fasteners fabricated from Type 304 stainless steel and as shown on the Plans and the Construction Notes sheet. All dissimilar metals shall be isolated with Teflon pads, UHMW isolation/bearing pads, nylon washers and/or nylon bushings as identified.

2.5 FABRICATION

A. Assemble helicopter pad in the shop to greatest extent possible to minimize field splicing and assembly. Disassemble units only as necessary for shipping and handling limitations. Clearly mark units for reassembly and coordinated installation. Use connections that maintain structural value of joined pieces.

B. Cut, drill, and punch metals cleanly and accurately. Remove burrs and ease edges to a radius of approximately 1/32 inch unless otherwise indicated. Remove sharp or rough areas on exposed surfaces.

C. Form work true to line and level with accurate angles and surfaces.

D. Fabricate connections that are exposed to weather in a manner to exclude water.

Provide weep holes where water may accumulate.

E. Cut, reinforce, drill, and tap as needed to receive hardware, screws, and similar items.

F. Welded Connections: Cope components at connections to provide close fit, or use fittings designed for this purpose. Weld all around at connections, including at fittings.

HELICOPTER PAD DELEGATED DESIGN AND CONSTRUCTION 13 21 10 - 4

1. Use materials and methods that minimize distortion and develop strength and corrosion resistance of base metals.

2. Obtain fusion without undercut or overlap.

3. Remove flux immediately.

4. Finish exposed welds to comply with NOMMA Guideline 1: "Joint Finishes," for

Type 2 welds: All welds are Type 1 welds.

5. Finish exposed surfaces smooth and blended and, except for fillet welds, so welded surface matches contours of adjoining surfaces.

G. Form exposed connections with hairline joints, flush and smooth, using concealed fasteners where possible. Where exposed fasteners are required, use Phillips flat-head (countersunk) screws or bolts unless otherwise indicated. Locate joints where least conspicuous.
