POV Washrack Demo RFIs and answers.pdf

1. During the site visit, I was unable to locate the lift station shown on the site drawings.

Could you please confirm its exact location?

Response: Lift station is located as shown on drawings.

2. I observed a large bare area around the asphalt driveway. Should the contractor sod only the areas disturbed by demolition, or is the entire bare area to be sodded? If the entire area, please provide dimensions. Is the entire asphalt area, extending to the end of the driveway, to be removed and replaced with sod?

Response: Sod is only required on areas disturbed by demolition.

2a. The Environmental Final Report Attachment contains sample summary results for 2 waste water samples from the oil water separator: 29-22 and 30-22. Have there been any other waste characterization samples collected from other liquids or other potentially hazardous materials on Site (that will require disposal)?

Response: There have not been any additional samples collected at the site. Disposal of any hazardous materials/wastes must be coordinated with 1 SOCES/CEIE, Mr. Steve Wiley.

3. Are there any active groundwater monitoring wells associated with the site? If so, will they need to be properly abandoned? Have there been any historic soil sampling of the upper soil column (0-10 feet below ground surface) for potential chemicals of concern at the Site?

Response: There are no active or inactive groundwater monitoring wells associated with the site. No COCs at the site or know soil contamination.

4. Will any additional sampling be required before or after demolition? For example, asbestos testing or sampling related to pit closure around the oil-water separator?

Response: Unless petroleum odors are encountered during the demolition of the facility, no samples will be required. The OWS is above ground and on concrete. The building does not have asbestos in it based on historic data.

5. Will the existing site grade be maintained, or is the contractor responsible for backfilling low-lying areas—specifically the slopes outside of the asphalt footprint?

Response: Maintain existing site grade. Maintain swale along road after removal of drive and culverts.

6. Is there any known asbestos in the building? If so, what are the types and quantities? Has an asbestos survey been conducted for the carwash structure? If not, should we include the cost and responsibility for this survey and any necessary abatement in our bid? Section

3.11 of the Performance Work Statement states “work areas known to contain or not to contain asbestos will be identified to the Contractor”; have these areas been identified?

Section 3.13.2 of the Performance Work Statement lists an Asbestos Abatement Plan as a submittal with “(if required)”. Is an Asbestos Abatement Plan submittal required if no Asbestos is identified at the Site?

Response: There is no known asbestos or any asbestos surveys have been done on 91021.

The facility was built in March 1999, and the AF has prohibited the use of asbestos in construction material well before the construction date. The asbestos abatement plan is not required if no asbestos is present.
