  1. General Requirements: To the maximum extent practicable, the shell of each booth shall be fabricated in the shop and erected in its pre-fabricated condition.
  2. All metals shall be free from defects impairing strength, durability, or appearance, and of best commercial quality for purposes specified. Metals shall be made with structural properties, to withstand safely, the strains and stresses to which they will be normally subjected.
  3. Visible surfaces of all metal shall be entirely free of dents, fractures, breaks, scratches, scars, patches, burns, stains, or other discolorations and shall possess uniform luster throughout. All metal edges shall be free of burrs; irregularities, sharpness or other defects such as may cause injury to persons encountering same.
  4. Welding shall be done in a thorough manner with welding wire of the proper alloy for the base material used. Welds shall be strong, ductile, with excess metal ground off joints, finished smooth to match adjoining surface. Welds shall be free of imperfections such as pits, runs, spatter, cracks, undercuts, etc., and seamlessly welded by an accepted process, except carbon arc welding. Butt welds made by spot welding straps under seams, filling in with solder and grinding will not be acceptable. Welds shall be either made or inspected by weldors currently qualified by tests as prescribed in the Structural Welding Code, AWS D1.1 of the American Welding Society.
  5. It is the intent of the Specification that all welded joints be homogeneous with the sheet metal itself. Any form of welding permitting carbon pickup will not be acceptable. Where sheet sizes necessitate a joint, such joint shall be skip welded, not tacked or attached by fasteners. Sides of booths shall be fabricated withwelded joint to eliminate all field joints.
  6. All work must be done in an approved workmanlike manner to the complete satisfaction of the owner or architect. Work to be performed by skilled crafts people experienced and versed in this kind of work.
  7. Booth fabrication in the shop shall be subject to inspection by the owner if desired.

PART 3 – EXECUTION

3.01 EXAMINATION

A. Examine substrates, areas, and conditions, with Installer present, for compliance with requirements for installation tolerances and other conditions affecting performance.

1. For record purposes, prepare written report, endorsed by Installer, listing conditions detrimental to performance.

2. Proceed with installation only after unsatisfactory conditions have been corrected.

B. Verify stub-ups and other related items are in position for proer installation of equipment specified in this section.

3.02 INSTALLATION

A. Install little buildings on 4-inch thick concrete (2000psi min.) bases that are 12 inches (minimum) larger than buildings in length and width. Keep bases flat to avoid torque of the buildings. Use rebar if substrate conditions require.

B. Set little buildings plumb and aligned. Level base plates true to plane with full bearing on concrete base.

C. Fasten little buildings to concrete bases using proper size stainless steel anchor bolts, such as Rawl, to meet local wind conditions. WARNING: Little Buildings must be properly anchored to meet local requirements. Adequate type and size of anchor bolts must be utilized to prevent structure from being blown over in high winds. Failure to securely anchor this product may result in personal injury or death.

D. Connect electrical power service to power distribution system according to the National Electric Code and local requirements. Provide ground rod.
