Suggested changes and environmental enhancements for possible inclusion in future revisions of this specification are encouraged. 7. TxDOT encourages all manufacturers to comply voluntarily with the Society of Automotive Engineers (SAE) Recommended Practice for marking of plastic parts per the latest revision of SAE J1344. All plastic components furnished to this specification should have an imprinted SAE symbol identifying the resin composition of the component so that the item can be recycled after its useful life. Manufacturers are encouraged to use recycled plastics and materials in the manufacture of their products in order to conserve natural resources, energy and landfill space. Bidders should note that future specification revisions may require mandatory compliance with the SAE plastic coding system. 8. TxDOT is committed to procuring quality goods and equipment. We encourage manufacturers to adopt the International Organization for Standardization (ISO) standards, technically equivalent to the American National Standards Institute/American Society for Quality Control (ANSI/ASQC Q ), and obtain certification. Adopting and implementing these standards is considered beneficial to the manufacturer, TxDOT, and the environment. It is TxDOT's position that the total quality management concepts contained within these standards can result in reduced production costs, higher quality products, and more efficient use of energy and natural resources. Manufacturers should note that future revisions to this specification may require ISO certification. 9. Measurements will be given in both the English and metric system. Where any conflict between the two stated measurements may occur, the measurements provided in the English system shall supersede those provided in the metric system.

It is the intent of this warranty that the vendor perform warranty repair work. At TxDOT's option, TxDOT may perform minor warranty repairs to the unit at the vendor's expense EXCLUSIONS: TxDOT will assume the expense for replacement tires and tubes, tire repairs, lubricating oil, hydraulic fluids, greases, filters, batteries, lights, hoses, belts, cleaning, painting, and other minor items normally consumed in day-to-day operations. TxDOT will assume responsibility for cost of repairs resulting from collision, theft, vandalism, operator negligence, and/or acts of God EQUIPMENT MAINTENANCE: It is TxDOT's policy to maintain the equipment in accordance with the manufacturer's published recommendations MINOR WARRANTY REPAIRS: It is the intent of this warranty that the vendor perform minor warranty repairs; however, at TxDOT's option, warranty repairs deemed by TxDOT as being minor in nature may be performed by TxDOT at the vendor's expense. Parts required for repairs which are to be made by TxDOT will be OEM parts and obtained at no cost to (or through reimbursement to) TxDOT. Only the actual time required for repairs shall be reimbursed. Mechanic's travel time, diagnosis time, etc., will not be included. Reimbursement by the vendor to TxDOT for the cost of warranty repairs will be computed as follows: Labor: Labor for warranty repairs will be calculated at the composite rate for the mechanic in effect at the time of the warranty repairs. Labor rate will not exceed $20 per hour. The time allowed for each repair will be determined by the manufacturer's standard time schedule. Manufacturer's time schedule shall be furnished to the receiving district with the unit at the time of delivery (if applicable). If a manufacturer's time schedule is not available, the actual time for repairs, as noted above, will be used Warranty Repair Claims: Warranty repairs will be accumulated on TxDOT repair orders (TxDOT Form No. 1614) and will be billed from same, unless the vendor prefers to have claims processed on the vendor's standard forms Parts: Replaced parts will be held thirty days and will be available for inspection by the vendor or authorized representative. Copies of the invoices for all parts will be provided to the vendor. The cost of parts other than those furnished to TxDOT at no cost by the vendor will be billed at actual cost Billing & Payment for Warranty Repair Expenses: Costs for minor warranty repairs will be accumulated, including labor and replacement parts (if not provided).
