6. B886/887/888: Will the contractor be responsible for moving the hydrant? Is there a designated area where they want the water cap and sewer cap?

a. See two attachments for the point of demarcations. Fire hydrants to remain.

7. B886/887/888: How much of the asphalt that appears outside of the red line in the photograph is to be removed?

a. The red outline is for the site visit location information only and does not represent any technical information for the job sites.

8. Will the two additional buildings be included in this proposal?

a. The two additional buildings, 533 and 541 are a separate requirement, set aside for HUBZone businesses only. The SAM posting notice ID is: FA461025Q0011

10. Is one technical approach required, or should it be separated by building or RFP?

a. Technical approaches should be separated by RFP.

11. Does the brush surrounding the building need to be cleared and grubbed, etc.?

a. Only for access to the work. All else may remain.

12. What happens to the building footprint—repave, backfill, or both? Is there a spec for topsoil material and quantity?

a. Any soil topsoil imported should be weed free. Soil amendments may be needed for topsoil and/or prepared to ensure native seed germination in any seed mix is used.

13. Is there a septic system at any building location, and are there any special requirements?

a. Septic system components should be cut and capped to prevent short circuiting of groundwater movement through any piping conveyances. Septic tanks shall be removed or demolished in place and holes punched through the bottom plate to allow groundwater percolation. Soil backfilling shall match hole volume by at least 100% to prevent soil subsidence.

14. Do all materials entering and leaving have to be logged thru hazmart on base?

a. Yes, all hazardous materials used onsite will be logged into the HAZMART system. In addition, any solid wastes (C&D) being removed must be tracked through the Solid Waste Program.

19. How deep below the surface will tree roots have to be removed?

a. With regard to any coast live oak tree > 6-inch dbh, avoid if at all feasible. This would potentially be in the vicinity of B886.

Trimming is preferred as needed. If any oak tree greater than 6-inches in diameter (dbh) is removed, an oak mitigation plan for replacement shall be developed with 1 year of maintenance. Coordinate plan with CEIEA at least one year prior to oak removal for approval or as soon as practicable. Replacement shall consist of 5-gallon size (minimum) trees obtained from locally-occurring saplings or seed stock of 10 for every 6-inch diameter or greater oak tree to be removed or significantly disturbed.

a. 800s appear to be on sewer line (see attached). No indication of leach at 533 per existing plan. 541 was part of an existing complex of building that were situated downslope and have since been removed. Assume leach is gone, cap sewer if it exists, departure from building.

23. What buildings have septic tanks and leach lines?

a. Unknown.

24. Will the contractor assume each building does not have unseen site conditions such as concrete vaults, basements, main water lines, main sewer lines, electrical pipe/duct banks, and gas lines within or under each building?

36. PWS 5.3 Engineering Data states, “For reference, as-built drawing is provided at Figure 5.” In reviewing the Solicitation documents it does not appear that this was included. Can the government provide the references as-built drawings?

a. This was a mistake in the PWS.

37. Can large steel track excavators be used? Can a 30’ x 30’ area of asphalt be removal directly next to the 886 building? This will give contractors a starting point to access the structures with steel track machines while preserving the surrounding asphalt.

a. Yes.

38. PWS 1.0 Introduction reads, “The Contractor shall furnish all parts, labor material, equipment, transportation and supervision necessary to demolish vacant Buildings 886, 887, and 888, including its basement, slabs, adjacent sidewalks, interior floor/walls/ceiling, exterior walls/roof/, and existing equipment (e.g. heating/sprinkler systems) and any furnishings within the building, as well as two shipping containers and abate and dispose of any Asbestos Containing Material (ACM) or lead-based paint (LBP) within or on the building, at Vandenberg SFB, CA.” During the self-guided tour, there was no evidence of a basement in any of the buildings. Can the government confirm that the buildings do not have basements?

a. Can not confirm. May request what info is available from CES GEO Office, but info may not be available. With the info they have, there is no indication of a basement at 533.

39. PWS 7.0 Environmental Requirements states, “The demolition of the buildings can only occur during bird non-nesting season, 15Aug- 15Feb. The demolition of the sidewalks and/or associated works can occur at any time during the year, although demolition may be delayed during the rainy season (November-March).” Does the government have an idea of when this project is scheduled for completion and confirm that it will not be during these restricted dates?

a. Demolition can occur year-round; however, between 15 Feb and 15 Aug if demolition is to occur, then a biological monitor will be required for the project to ensure no nesting birds are in the structures. The cost of the monitor(s) is a requirements of the project. All monitors must be pre-approved through the 30 CES/CEIE (Environmental) Office.

b. Prior to any work starting, the project proponent is responsible for having an asbestos and lead-based paint survey performed by a third-party Certified Asbestos Consultant (CAC) independent of the abatement team, for each building.

41. There is a seed mix supplied for buildings 533 and 541. Can the government confirm that this seed mix is also required for the 800 buildings?

a. If a seed mix is needed, approval is required by CEIEA. Coordinate native coastal scrub seed mix and approval with CEIEA.

a. The red outline is for the site visit location information only and does not represent any technical information for the job sites.

43. The response to a previous RFI-QA doc states that a performance and payment bond is required for this project. After reviewing the

1449 I do not see any reference to bonding requirements or a clause substantially the same as the clause at 52.228-16.

a. Bonding requirements have been/will be removed.
