It shall be equipped with all the manufacturer's standard equipment and accessories which are part of the standard published literature. If optional equipment is identified on the invitation for bid (IFB) it shall only be supplied and installed when included as a line item on the Purchase Order. The body shall be supplied as a complete, welded, working assembly free from any defects that would hinder its appearance or serviceability.

The unit shall comply with Caltrans Equipment Quality Standards for Welding, and Coatings as defined at: http://www.dot.ca.gov/programs/equipment. The Contractor will be responsible for complying with these standards.

If a discrepancy is discovered between the specifications and the drawing(s) provided, the Contractor shall request clarification from the Department of General Services (DGS). The specifications and drawing(s) shall have precedence over the completed questionnaire and standard factory specifications or literature. The Bidder’s completed questionnaire shall take precedence over the standard factory specifications or literature.

If any referenced item listed on the drawings or in the specification is offered as an equivalent to the specified reference brand, then the Division of Equipment Specification Engineer will evaluate and determine compliance. Only technical changes authorized by DGS in writing will be accepted. Technical changes made by any other Division of Equipment, Caltrans, or State employees will not be accepted in accordance with the IFB.

Any deficient weld shall be corrected by a welder who is certified in accordance with the requirements as established by the American Welding Society (AWS). The welder shall have the proper certification documents indicating that he/she is qualified to perform the type, size, and position of the weld performed, with the welding process utilized, and on the material being welded. The Contractor will be required to supply proof of current welding certifications for personnel performing any re-welding on the unit, upon request of the State whether written or verbal.

GRINDING OF WELDS must have prior approval of the Department of Transportation, Division of Equipment, Engineering Specifications. Welds which have been ground without approval shall be subject to complete re-welding upon request, at no additional cost to the State.

When drawings are supplied, the assembly dimensions and tolerances shall apply after welding. Excessive warpage of assembled parts is not acceptable. Weld symbols on supplied drawings shall be interpreted per American National Standard Welding Symbols. In the event of the lack of a weld symbol, the best commercial practice shall prevail. The covering of welds with body fillers or similar materials is unacceptable.

Material which is joined by welding or other means to form a single piece of stock is not acceptable. The finished product shall be free of dents and warpage. The use of any type of body filler is unacceptable. All bolts shall be Grade 5 or better and conform to SAE and ASTM standards. Bolt lengths shall be such that a minimum of two threads shall extend beyond the nut. Nuts shall be the locking type. Nuts and washers shall be compatible with the bolt(s) to which they are attached, as recommended by the fastener manufacturer and in accordance with SAE and ASTM standards. If requested, the Contractor shall submit proof of fastener strengths.

Radii shall be at least twice the thickness of the material or in accordance with the requirements established by ASTM for the particular material being formed, whichever is greater. All holes shall be round, of the proper dimension, perpendicular to the material they are produced in, and finished smooth. Oblong holes or holes drilled, bored, etc. at angles are not acceptable. Holes and slots shall be drilled, punched, saw cut, plasma cut, or milled; torch cut is unacceptable. Sharp corners on all material shall be radiused to prevent personnel injury.

FABRICATION: The body, shall be fabricated in such a manner (ie – using tooling, fixtures, jigs, etc.) that all critical dimensions are uniform and consistent from one unit to another. The body shall be manufactured so that they are interchangeable from one chassis to another.

The State reserves the right, prior to award of Contract, to inspect a potential Contractor’s manufacturing facility to ensure the manufacturer is a “responsible contractor.” Such an inspection would include, but not be limited to, scheduling, production capability, manufacturing procedures and processes, documentation, etc.

PAINT: The basic unit, the primary finish surfaces of any optional equipment, and other minor or incidental component parts shall be finish painted with lead-free (300 PPM LEAD MAX) standard factory color(s). The finish coat shall be free from runs, drips, sags, etc., and shall be evenly applied to provide a gloss finish.
