Major Mechanical Upgrades Seattle TRACON (S46) and Seattle ATCT (SEA)

Questions and Answers

July 26, 2024

1. Section M, Page 68, paragraph 3: For Tier 1, is the FAA’s definition for Small, Disadvantaged

Businesses (SDB) for socially disadvantaged and economically disadvantaged owned businesses only or does it include other programs such as HubZone and SDVOSB ?

FAA Response: SDB is a stand-alone category and does not automatically include HUBZone and/or SDVOSB status. Vendors would have to be self-certified in SAM as a SDB or be a certified

8 (a) to qualify for Tier I. As the solicitation is written, HUBZone and SDVOSB firms would be eligible in Tier II.

2. With these sites being secure and badging required, how many personnel can be badged per company or discipline?

FAA Response: Badging can be setup to get Contractor PIV badges. This will require going through security and doing appropriate background checks. Once a PIV card is obtained, an escort is no longer required within the facilities. The access badge is still on the HID proxy cards which are issued separately. Usually only the Foreman and/or Superintendent receives a badge.

On average 1-2 badges are allowed, but additional requests can be reviewed.

3. For previous projects in the past at these facilities, we have not been allowed to get everyone badged, how many non-badged personnel can a badged employee escort.

FAA Response: This is facility dependent. It is possible to get FAA PIV badges for key personnel and that allows the superintendents and other leads to escort unbadged personnel. When working, unbadged personnel must be within the vicinity of the PIV badged escort. The number of workers can vary depending on the location and type of work.

4. Can the badging process be completed at either facility or do subcontractor employees have to go to the Regional Office for badge processing?

FAA Response: Badge processing will be done at a designated office by the facility. The Regional Office is located south of the airport.

5. Will there be a requirement to work any night shifts? If so, how many nights are expected and in what areas?

FAA Response: Yes, night shifts will be required for work in operational spaces. Equipment cut overs may also be required to be performed at night due to risk to the facility operations during high traffic hours.

6. Will air scrubbers be required for any painting or other work that will create odors?

FAA Response: Work will require paint and chemicals with low VOC to limit odors. If that is not possible than other mitigations will have to be taken. These are manned facilities with operational staff in them at all hours of the day.

7. Is there a limit on how many vehicles are allowed in the gated areas for this work?

FAA Response: Yes, space is limited in each facility. Parking is reserved for onsite staff. Some space for essential vehicles will be provided. S46 has more space and SEA is very limited.

8. Will both of these projects run at the same time, or will one finish before the other gets started and which one would be first if that is the case?

FAA Response: This is addressed in the contract documentation. In the Construction SOW under section 1.

9. Is there asbestos or lead paint in either of these projects? Please provide the Hazardous material report for each project.

FAA Response: This is one single project with separate task orders.

For the SEA ATCT, asbestos is presumed in gaskets in various locations. In addition, 12” gray vinyl floor tile on the First Floor has been tested to contain 0.25” Asbestos. Approximately 1200 SF exists, however this will not be affected by the scope of this project.

For the S46 TRACON, asbestos is presumed in gaskets in various locations.

Hazardous material is addressed in contract documentation.

10. Can you send out the sign in sheet for this project?

FAA Response: If you are referring to the site visit sign-in sheet, yes. It has already been released as an attachment on SAM.gov.

11. Will work areas be vacated by government employees while work is being done or will the contractor need to work around existing employees during this contract?

FAA Response: These are 24-hour operating facilities. Please see contract documentation.

12. Will there be other contracts ongoing during this work that will interfere or complicate the schedule in any way?

FAA Response: This is a long project, and it is not clear if other work will be happening at this time. Other work is planned to be completed in the near future but has not been confirmed.

13. Please provide access flooring specifications and identify modifications for the new crac unit on the 15th floor. What manufacturer is the existing access floor?

FAA Response: The floor tiles are Maxcess R2F2 panels. They are rated for a design uniform load of 371.75 lbs/ ft2.

14. How long can the floor be opened up to modify the crac unites and add a new crac unit on the 15th floor? How much can be opened up and for how long?

FAA Response: This is dependent upon various factors such as outdoor temperatures which in return can affect in door temperatures. Close monitoring of the systems will be required. Safety barriers shall also be used when the floor is opened for extended periods of time and work is not in process.

26. Are there any temporary heating/cooling requirements?

FAA Response: See contract drawings referencing temporary heating/ cooling design. The facility is a 24-hour operational site, this requires that the equipment and spaces within the facility will be comfortable and within operating temperatures during the duration of the project.

FAA Response: Refer to the design drawings on demolition and installation plans. Only conduit may be reused where feasible.

ATCT:

35. Sheet Ad101 note C indicates to patch Deteriorated and damaged concrete decking and parapet wall upon exposure to existing roof deck and parapet. We will not know how much patch and repair will need to take place as it is not currently exposed. Can you give us an allowance to bid for the project so it can be adjusted up or down depending on how much repair is actually required?

FAA Response: That risk should be assessed by contractor. A reasonable amount should be factored in for this existing roof. This is a firm-fixed price contract.
