A: Yes Q: Does the airport really want Mode 1 signs? Most airports go with Mode 2 and I am not even sure if anybody makes Mode 1 anymore. A: The signs should be Mode 2. Q: Can excess excavated material be wasted on site? A: The Airport Owner will allow excess material to be placed on airport property or other location nearby. (Please see addendum documents for further details on requirements of placing this material on Airport property) Q: Is water available? A: There are multiple hydrants nearby to choose from. The City will allow Contractor to take water on an honor system basis for payment to the City. The Contractor should report to the City how many loads of water they took. Q: The company that applies the Thermoplastic Coal Tar requires all the paint to be removed in order for their material to properly adhere. I noticed there was no pay item for paint removal. Are you considering paint removal incidental to surface prep or the P-620? Normally there is a pay item for paint removal. A: A pay item for paint removal will be added. Please see addendum documents for further information. Q: I would like an official written answer to stop some confusion we have had regarding the DBE plan submittal, and if everyone is required to turn in a DBE plan then the wording in the bid docs should to be changed to reflect that. A: Please note this statement is TxDOT’s official position which overrides any discussion in the prebid meeting: “Only the apparent low bidder must have their DBE plan submitted by midnight of July 26, 2020 to be considered responsive.” Q. Does the engineer or project representative require a job trailer on the project site? A. No Q: Is a gate guard required for this project? A: No Q: Can you provide any details for the “P-101. Removal and disposal of existing stake-mounted runway threshold lighting fixture”? I don’t see a detail or description of the existing light fixture in the plans. A: Please see Plan Sheet 33. On each runway end, there are notes that read “Install L-867 junction can and splice new cabling into existing MIRL circuit and remove and dispose of Ex.
