PART 3 EXECUTION

3.1 FABRICATION

Material with welds will not be accepted, except where welding is definitely specified, indicated on the drawings, or otherwise approved.

Bends, except for minor details, shall be made by approved dies, press brakes, or bending rolls. Where heating is required, precautions shall be taken to avoid overheating the metal and it shall be allowed to cool in

SECTION 05 50 14 Page 3 such manner as not to destroy the original properties of the metal.

Shearing and cutting shall be accurately done and all portions of the work shall be neatly finished. Cutting shall be done by saw, water-jet, or high definition plasma arc. Corners shall be square and true unless otherwise shown on the drawings. Finished members shall be free from twists, bends, and open joints.

3.2 WORKMANSHIP

All workmanship shall be of the highest grade in accordance with the best modern practices to conform to the specifications for the item to be furnished. All similar parts shall be interchangeable. All sharp edges and corners shall be broken. All holes shall be normal to the surfaces of penetration and shall be sized as indicated on the reference drawing.

All holes shall be drilled or laser cut.

3.3 FINISHED AND DRILLED SURFACES DIMENSIONS AND TOLERANCES

Tolerances for drilled and machine-finished surfaces designated by non-decimal dimensions shall be within +/- 1/64 inch unless otherwise noted on the drawing.

3.4 UNFINISHED SURFACES DIMENSIONS AND TOLERANCES

Unfinished surfaces shall be true to the lines and dimensions given on the drawing and shall be ground free of all projections and rough spots.

Tolerances shall conform to industry practices. The cut dimensions of the structural steel items shall be + / - 1/16".

3.5 PACKAGING AND DELIVERY

The Contractor shall package and label all items in accordance with the Schedule of Prices heading that the items fall under.
