Response: Refer to revised specification section 22 0000 issued as part of

11) Question: Sheet P2.2 shows the NG-1 Nitrogen Generator overlapping the tire cage.

The footprint of the Nitrogen Generator on the plans matches the size of the specified unit. However, in addition to nitrogen storage bottles that are part of the system, the manufacturer advises that several feet of clearance is needed for the generator. Please advise if any of these components can be or should be relocated, as this appears to require more than just field coordination and will impact that amount of SS tubing required for connection.

Response: Designed acknowledges potential conflict. Refer to revised drawing sheet P2.2 for revised notional configuration. Contractor will be required to field verify all dimension and coordinate equipment sizes and clearances for all equipment intended for installation with the manufacturer selected by the bidder to furnish the equipment required to meet the design intent and requirements.

12) Question: Sheet P2.1 shows a direct buried fuel spill storage tank. Is there a Civil or outside drawing showing where this is to be located in reference to the site?

Response: Drawing sheet P2.1 is accurate regarding the location of the tank relative to required piping lengths etc… See screenshot below for overlay of the plumbing drawing with the existing base utility map. As indicated in the screenshot, the new plumbing and vent piping will cross one known existing water utility. The Government will locate utilities and provide a dig permit prior to excavation. Contractor will be required to pothole and verify depth of existing water utility in order to field verify and coordinate exact tank placement and depth to coordinate with existing water utility.

Is this an option the contractor can elect to perform or is this required 3rd party testing for air contaminants that the contractor must carry costs for?

Response: Air testing is an acceptable alternative to building flush out. The Contractor may elect to hire a testing agency to conduct air contamination testing prior to conducting a building flush out. If air contamination testing documents acceptable contamination levels, the building flush described in section 3.02 will not be required. If higher than allowable air contamination is detected during testing, a building flush out and re-testing will be required. The Contractor shall bear the cost of all air contamination testing.

56) Question: Spec Section 01 5719 Paragraph 3.01 Construction Procedures. Paragraph

3.01 Letter D. States that the use of HVAC equipment and ductwork for ventilation during construction is not permitted.
