00997.75 30-Day System Acceptance Test – - Prior to acceptance, the complete system will be required to exhibit satisfactory system operation and reliability by passing a 30 consecutive day, trouble free period of operation. The test shall be conducted after successful completion of the site test and approval by the Engineer. The purpose of this test is to demonstrate that the total system is properly installed, if free from identified problems, complies with the specifications, and exhibits a reliable performance level. Failure of any Contractor furnished hardware item during the test shall necessitate a restart for the full 30-day duration after all repairs and replacements have been made. The Engineer may shorten the length of retest depending on the failure but in no case shall the total test duration be less than 30 consecutive days. No intermittent problems will be permitted to persist during the test. If such problems are encountered, the test shall be halted until the problem is corrected. All system documentation shall be corrected to reflect changes made during the test period and resubmitted to the Engineer before final system approval. 00997.76 Warranty - Provide a one year Contractor warranty according to 00170.85(b). This Contractor warranty does not replace or reduce other warranties, including manufacturer’s warranties, that are longer than one year.The warranty of 00170.85(b) applies to work under this Section. Measurement 00997.80 General – - There will be noNo measurement of quantities will be made for work performed under separate measurement of work done under this Section. Payment 00997.90 Payment - The accepted quantities of work performed under this Section will be paid forfollowing item will be paid for at the cContract lump sum amount: for the item: Pay item Unit of Measurement (a) Variable Speed Sign Installation Lump Sum Item (a) includes pedestrian pedestal and foundation, mounting hardware, variable speed signs and controller, external relay, and communication cables.
