Question Number  1:   Project Manual, Part 1 – Project Requirements, 2019 AAPR Bid Form Phase 4 – Federal, Page 43 of 170 of the PDF File has the Item: P-150a – Remove PCCP (Non-Reinforced, 17”) with a quantity of 2,638 SY and two P-501a – PCCP (Non-Reinforced, 17”) items, both with a quantity of 2,638 SY, for a total of 5,276 SY of 17” Non-Reinforced PCCP. Please confirm that there should only be one Item for P-501a – Portland Cement Concrete Pavement (Non-Reinforced, 17”) with a quantity of 2,638 SY.
    Answer:   Yes, there should only be one item for P501a-Portland Cement Concrete Pavement (Non-Reinforced, 17”) with a quantity of 2,638 SY. See addendum 1 for revised bid form.
Question Number  2:   Does this project include any grooving?
    Answer:   No, the project does not include grooving.
Question Number  3:   Does the TP on the fixture symbols refer to masking off the lights with reflective tape? And if so, who is responsible for this work, the contractor or DEN? Is there a line item on the SOV for payment?
    Answer:   Yes, the TP on the fixture symbols refers to masking off the lights with reflective tape. DEN inspectors will work with the contractor to mask off the lights. No, there is no line item for this work on the SOV for payment. The masking off of lights with reflective tape is incidental.
Question Number  4:   What is the reasoning for the high number of transformers needed compared to the number of fixtures being removed and replaced?
    Answer:   The higher number of transformers required includes installing new transformers in all light cans that require the fixture to be removed. This includes cans to be demolished, cans to be blanked, and cans that require jumpers.
Question Number  5:   The number of B (blanks) on drawings to the number on line item L-125d do not match. Please verify?
    Answer:   The line item L-125d quantity is correct on the revised bid form, see Addendum 1.
Question Number  6:   The number of LC (light cans) on drawings to the number on line item L-125a and L-125b do not match. Please verify?
    Answer:   The line items L-125a and L-125b quantities are correct on the revised bid form, see Addendum 1.
Question Number  7:   On sheet number 37, please verify number of H cans? Are the (G)s meant to be (H)s?
    Answer:   On sheet number 37, the number of H cans are 9 . Yes, the (G)s are meant to be (H)s.
Question Number  8:   On sheet #8 of the Pavement Details the “ Reinforcing Mat For Light Can Reinforcement “ shows just the mat. When detail refers to the mats being placed around can, does this mean that the can is placed thru the center of the 2 mats? Please clarify?
    Answer:   Yes, the can shall be placed through the center of the two mats.
Question Number  9:   Can QC Technicians, per spec section 01 45 25, that are performing material testing also serve as the QC inspectors; or will QC inspectors be required, per 01 45 10, in addition to the testing technicians?
    Answer:   QC inspectors will be required, per 01 45 10, in addition to testing technicians.
Question Number  10:   Sheet 4 of 41, Note 4, states all haul route damage is to be fixed at the expense of the contractor. Are all paved areas designed to handle CDOT legal loads? If not, will the contractor be required to fix these areas at their own expense if they are damaged by CDOT legal loads.
    Answer:   There has been no structural analysis performed on the proposed haul route roads. The expectation is that any damage caused to the haul route roads, during haul operations, will be repaired at the contractor’s expense.
Question Number  11:   Will WWF D6xD6 at 6-inch spacing be allowed on this project in lieu of #4 bar on 12-inch centers each way for the reinforced panels?
    Answer:   Yes, welded wire fabric (WWF) D6xD6 at 6-inch spacing will be allowed on this project in lieu of #4 bar on 12-inch centers each way for reinforced panels.
Question Number  12:   If WWF is allowed, will it need to be epoxy coated?
    Answer:   No, the WWF will not need to be epoxy coated.
Question Number  13:   Spec section P-150-1.9.a states in paragraph 3 that an alternative removal method may be accepted to sawing and lifting panels. Please confirm that the removal methods must be by lifting and that breaking of the concrete will not be allowed.
    Answer:   Lifting and breaking of the concrete will not be allowed.
Question Number  14:   Plan sheet 7 detail (4) note 1 states that the portion of the basket in contact with the subgrade must be epoxy coated. Plan sheet 8 in the Construction Joint Dowel Basket detail states that all steel should be epoxy coated. Sheet 8 states in the Reinforcing Mat For Light Can Reinforcement detail that all steel shall be epoxy coated. Spec section P-501-2.7 paragraph 2 states that dowel assemblies, tie bars, and other miscellaneous steel shall be epoxy coated. It seems unclear what the requirements are. Are rebar support chairs to be partially or fully epoxy coated? Are dowel basket assemblies to be partially or fully epoxy coated. Is rebar to be epoxy coated?
    Answer:   Rebar support chairs and dowel basket assembles are to be partially epoxy coated. Rebar is to be epoxy coated.
Question Number  15:   Are the panels with light cans shown in the drawings that are not irregular shaped to be fully reinforced or only reinforced with the detail shown around the light cans? What pay item will the reinforcing for light cans be paid under?
    Answer:   Are the panels with light cans shown in the drawings that are not irregular shaped to be fully reinforced or only reinforced with the detail shown around the light cans? What pay item will the reinforcing for light cans be paid under?
Question Number  16:   Sheets 17-21 of 41 do not clearly call out who provides the low-profile barricades. Who will provide the low-profile barricades in phases 1A, 1B, 2, and 4?
    Answer:   Contractor to provide all barricades for construction area delineation for phases 1A, 1B, 2, 3 and 4.
Question Number  17:   Where low-profile barricades are to be provided by others, who sets and removes the barricades?
    Answer:   The low-profile barricades are to be provided by others will be set by other and picked up at the end of the project by other.
Question Number  18:   Sheet 19 of 41 calls out “Re-routed VSR Marking, to be performed by others” but Note 1 on this sheet states “VSR Relocation from Phase 2 to be performed by Contractor.” Who is responsible for this work?
    Answer:   VSR Relocation from phase 1B to phase 2 placement to be performed by Contractor of the 2019 Annual airfield pavement rehabilitation project in coordination with DEN PM, Operations and B-WEST expansion team.
Question Number  19:   Phase 4, Bid Item P-501a is duplicated. Is a new bid schedule going to be provided?
    Answer:   Please see Addendum 1.
Question Number  20:   There is conflicting information regarding the contract time. Please clarify which scenario is correct. From the specifications, the contract time is 200 consecutive calendar days. From the plans, sheet 6, Phase Schedule, the contract time is about 103 calendar days.
    Answer:   The total contract time is 200 consecutive calendar days. The 103 days listed in the plans are an idealized situation in which there are no changes to phasing due to impacts from other projects.
