Question1: Please provide the specification for the 1/16" epoxy floor finish.

Answer: Please refer to UFC 3-190-06 and references found therein.

Question2: The walkway dimension length is shown as approximately 152". Please confirm that the walkway is to be replaced from the exterior of the building, through the first, unused chamber, and then replace and reconfigure the

2nd walkway located in the chamber with the actual tank in it. New walkway in this chamber to fit around the new tank.

Answer: I do not understand what is meant by "replaced from the exterior of the building". Only the walkway inside of the chamber containing the tank is to be replaced.

Question3: In the chamber outside of the chamber with the sulfate tank there is an existing sump pump in an existing pit. In the solicitation the 5.4 demolition of this sump pump has been crossed out however the new work

10.2.4 references supporting new sump pit piping. Please describe what work will take place, if any, at the sump pit and existing sump pump.

Answer: Overflow pipping running from the filler pipe to the sump pit is to be replaced. The all new piping that runs above the floor shall be supported every 40 inches of length. Existing sump pumps are to remain.

Question4: The existing lifting bolts on the precast roof panels have been cut off and temporary attachments will need to be installed as part of the removal. Please confirm that professional engineer will be required to provide lifting hardware design as part of the lift plan for these panels.

Answer: The Contractor shall provide their own engineering services to provide lifting hardware design as part of the lift plan.

Question5: Please confirm that the crane needed to remove these concrete roof panels and for the removal of the old tank and installation of the new tank will require sixty (60) day notice in order to set up in the flight line path.

Answer: It will take at least 45 days for approval of the crane waiver.

Question 6: Please confirm the both cells floors and walls up to 2' are to be coated or is just the cell where the tank is located is to be coated.

Answer: The floors and walls in both cells are to be coated.

Question7: The outside wood platform attached to the building appears to be where the driver will stand when filling the tank? There is no work currently in the scope of work for anything on this walkway. Please confirm if replacement of the deck boards are to be added to this scope of work.

Answer: No, replacement of the wood platform is not included in the scope of work.

Question8: Inside the first chamber, before entering the chamber housing the tank to be replaced, there is an existing sump pump that does not appear to be operational (float was up and pump was not on). Please confirm if replacement of this pump is to be added to the scope of work.

Answer: No, replacement of the sump pump is outside the scope of this project.

Question9: The Wage Determination is shown as 'Service Contract' which are not applicable to the construction of the new walkway, installation of new tank, demolition of old tank. Please provide the construction Wage

Determination to be used for this task order.

Answer. See Attachment A - Wage Determination - Davis Bacon.

Question10: Please confirm whether a Bid Guarantee is required for this Solicitation?

Answer: Yes, Bid guarantee will be required.

Question11: Please confirm whether a Payment and Performance Bond will be required after award.

Answer. Yes, Payment and Performance Bond will be required after award.

Question12: We are asking for the original submittal data and drawings on the existing tank. This is necessary so that we provide a new tank that exactly matches the existing tank to be demolished.

Answer: See Attachment B - Drawing for the existing tank

Attachment C - Concept Drawing for the Alum Feed System

Question13: There are no drawings for the work in the documents. The scope of work indicates and describes a new access platform. Is the contractor required to design & PE Seal this work as part of the materials to be provided and installed?

Answer: We don’t think contract is required to design and PE seal as part of the materials to be provided and installed. However, contractor will need to have in-house capability to procure proper materials meeting industrial standards and construct new access platform meeting applicable industrial standards and UFGS-05 50 13 requirements. For example, contractor will need to use non-corrosive, chemical (alum) resistant and properly sized anchors, fasteners, and other hardware that are used for access platform and tank saddles fixed/anchored on the floor/walls.

Contractor are required to provide submittals/construction plans to FEAD construction manager and MCBQ SMEs

(Engineering/Utilities) and get approval before ordering materials and constructing them.
