Included within these requirements are specified components, equipment and systems usually accompanied by the phrase "or approved equal." Such components, equipment and systems, or deviations and substitute items specifically approved by the Authority, shall be provided as part of the completed tow truck under the Contract. The Authority’s specification of such components, equipment and systems and/or the approval of such items shall not relieve the Contractor of any obligation under the Contract since the Authority expects and is relying on the Contractor, in designing and testing the tow truck, to verify the suitability and safety of materials, components, equipment, systems and items before incorporating them into the design, fabrication or assembly of the truck provided by Contractor.

Without limiting the general provisions or other requirements of these specifications, all work included herein shall conform to or exceed the applicable requirements and as approved by Jacksonville Transportation Authority. Reference to other sections or specific provisions of the Contract, including these technical specifications, is only for the convenience of the Contractor.

Failure of the Authority to refence one or more requirement(s) accurately or completely to other related requirements shall not relieve the Contractor of its obligation to fully understand and correlate all of the Contract's requirements.

Reference to standard specifications, manuals or codes of any technical society, organization, or association, or to the codes, laws, or regulations of any governmental authority, whether such reference be specific or by implication, shall mean the latest standard specification, manual, code, or laws or regulations in effect at the time of submittal of proposals except as may be otherwise specifically stated.
