Workmanship:

All work and materials shall be in accordance with the best manufacturing practices, and complete in all respects, and comply with the applicable requirements of the U.S. and California.

Component parts of the unit shall be new (unused), current model year production, and of proper size and design for safe operation. The equipment shall be provided with components, accessories, materials, design practices, and workmanship that are the best available in the industry for the equipment type, and suitable for locations where the vehicle shall be used. The manufacturer's recommended torque rating of each driven part shall be equal to or exceed the torque rating of its driving member. The equipment shall be a product of good workmanship and shall be free from any defects that will affect their appearance, use, or serviceability.

Material:

Construction shall be of all new (unused) material free of rust and any defects. All structural components in the assembly shall be fabricated from a single piece of material. Spliced components are not acceptable. Brackets, gusset plates, etc. to be welded shall be of the same material as the adjoining material. The finished product shall be free of dents and warpage. The use of body filler is unacceptable.

Fasteners:

Bolts and washers shall comply with the most current engineering and manufacturing practices and standards. Frame (flange) bolts and nuts shall be used to attach components to the vehicle frame. Frame bolts and nuts shall be of compatible material to prevent electrolysis with frame members. Bolt lengths shall be such that a minimum of two threads shall extend beyond the nut when tightened. Nuts shall be the locking type.

Structural members shall use Society of Automotive Engineers (SAE) Grade 8, or better, bolts with matching nuts.

Non-structural members shall use SAE Grade 5, or better, bolts with matching nuts.

Metal Shaping:

All breaks shall be free of cracks. Radii shall be at least twice the thickness of the material or in accordance with the requirements established by ASTM International 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 rounded smooth to prevent injury.

Welding:

Welding shall comply with the most current standards as set forth by the American Welding Society (AWS) and the American National Standard Institute (ANSI). Intermittent or spot welds shall be spaced and proportioned to provide ample strength for the material being welded. Weld sizes not indicated shall be equal to the thickness of the least of the joined plates.

All welds shall be properly fused, displaying proper penetration and a professional finish, and must meet the qualification requirements of applicable AWS specifications. Examples of unacceptable welds are:

Any weld failing to comply with the AWS specification or failing to pass a quality assurance inspection performed by the State, shall be corrected by the manufacturer at the manufacturer’s expense, and be corrected off State property. weld shall correct deficient welds.

Grinding of welds must have prior approval of the Department of Water Resources’ (DWR’s) Fleet Management Branch Engineering Section. Welds that have been ground without approval shall be subject to complete re-welding upon request, at no additional cost to the State. The covering of welds with body fillers or similar materials is unacceptable. Warpage of assembled parts is unacceptable.

Electrical System:

All wiring installed shall be the stranded copper type and shall have cross-linked polyethylene insulation. All wiring shall be protected in a plastic loom or conduit, unless otherwise specified. Adequate size gauge of wire to the lights shall be used in accordance with SAE standards for distance from power source and load demand. The ends of all stranded conductors cut shall be mechanically stripped and fitted with insulated type terminals. The terminals shall be mechanically crimped securely with appropriate tool(s). All splices and connections shall be sealed against moisture. Scotch Lock wire-piercing devices shall not be used. Ground return connections shall be attached to the vehicle frame, body and/or engine. In cases where the engine or body is mounted on rubber or other insulation, proper ground shall be provided with grounding straps.

Hydraulic System:

Hydraulic lines shall be sized as recommended by the manufacturer of the component to which they attach and shall be adequate for the use intended. All hoses and plumbing shall have a minimum number of bends and shall be free of any kinks. All bends in hoses and tubing shall be not less than the minimum radius as recommended by the hose or tubing manufacturer. Where applicable, plumbing components shall be protected by frame members. Any hoses routed around or through areas, which may cause abrasion and cuts, shall be protected as necessary. Through holes for routing hose and tubing shall include grommet. All hydraulic components and plumbing shall be mechanically mounted and supported to withstand extensive field use. Adhesive type mounting will not be accepted. Fittings shall be of the proper size to match the hydraulic line to which they attach. Compression type fittings shall not be used in the system. All threads shall be North American type threads. British, metric, etc. threads are unacceptable. The use of black pipe, galvanized pipe, pipe fittings, etc. shall not be used in the hydraulic system.
