PERFORMANCE REQUIREMENTS

Structural Performance: Engineer, fabricate, and install press box to withstand the design loads specified in NFPA 102, "Standards for Assembly Seating, Tents, and Membrane Structures" Chapter 4, "Grandstands and Bleachers", without exceeding the allowable design working stresses of the materials involved, including anchors and connections. Apply each load to produce the maximum stress in each respective component of each bleacher unit.

SUBMITTALS

Product Data including details of construction relative to materials, dimensions of individual components, profiles, and finishes.

Shop Drawings showing fabrication and installation of bleachers including plans, elevations, sections, details of components, and attachments to other units of Work.

Include structural analysis data signed and sealed by the qualified professional engineer responsible for their preparation.

Samples for Initial Selection: Manufacturer's color charts consisting of actual units or sections of units showing the full range of colors, textures, and patterns available for each exposed material involving color selection.

QUALITY ASSURANCE

NFPA Standard: Comply with NFPA 102, "Standard for Assembly Seating, Tents, and Membrane Structures" Chapter 4, "Grandstands and Bleachers" except where more stringent requirements are indicated or imposed by authorities having jurisdiction.

Installer: An experienced Installer that has specialized in installing bleachers similar to those required for this Project and who is acceptable to, or certified by, manufacturer of bleachers.

Professional Engineer: A professional engineer who is legally authorized to practice in the jurisdiction where Project is located and who is experienced in providing engineering services of the kind indicated. Engineering services are defined as those performed for installations of bleachers that are similar to that indicated for this Project in material, design, and extent.

Welding Standards: Comply with applicable provisions of AWS D1.1 "Structural Welding Code--Steel" and AWS D1.3 "Structural Welding Code--Sheet Steel."

Engage certified welders that have satisfactory passed AWS qualification tests for welding processes involved and, if pertinent, have undergone recertification.

Engineering Responsibility: Engineer grandstands by qualified professional engineer legally authorized to practice in jurisdiction where Project is located.

PROJECT CONDITIONS

Field Measurements: Check actual dimensions of construction affecting grandstands by accurate field measurements before fabrication and show recorded measurements on Shop Drawings. Coordinate fabrication schedule with construction to avoid delaying the Work.

PRODUCTS

MANUFACTURERS

Manufacturer Qualifications: Manufacturers must prove that they have contracted and provided the design, manufacture, and installation of bleachers/grandstands as current business organization for a minimum of 5 years. Bidders must provide a list of 5 similar projects completed in the State of Michigan in the past 3 years.

Welders must be AWS certified. Manufacturer to be AISC Certified.

Manufacturers: Subject to compliance with requirements, provide products by one of the following:

Southern Bleacher Company, Basis of Design.

Other manufacturers seeking to be approved must submit product literature on horizontal beam design and deck system to the Owner for review and receive approval from Owner seven days prior to bid date. Prior to bidding, Manufacturers must provide a list of a minimum of 5 (five) projects of similar product type and project size contracted and completed within the State of Michigan within the last 3 years.

Approval does not relieve manufacturer of providing minimum criteria mentioned above.

Qualified manufacturers must, also, provide proof of approval by the State of Michigan to manufacture press boxes in the State of Michigan.

MATERIALS

Metal Surfaces: For exposed surfaces, provide materials selected for surface flatness, smoothness, and freedom from surface blemishes. Do no use materials with exposed pitting, seam marks, roller marks, rolled trade names, or roughness.

Structural Steel Shapes, Plates, and Bars: ASTM A 36, except where higher strength steel is indicated or standard with manufacturer.

Steel Tubing: ASTM A 500, cold formed, hot-dip galvanized coating per ASTM A 53.

Extruded Aluminum: ASTM B 221, alloy 6063-T6.

Galvanizing Repair Paint: High-zinc-dust-content paint for regalvanizing welds in galvanized steel, with dry film containing not less than 94 percent zinc dust by weight, and complying with DOD-P-21035 or SSPC-Paint 20.

Bituminous Paint: Cold-applied asphalt mastic complying with SSPC-Paint 12, except containing no asbestos fibers. Used as a barrier between dissimilar metals.

COMPONENTS

A. Product Description
