Joint Base Charleston, SC

REGARDING ITEM R1 – Rubber Removal, Chemical Method

1. QUESTION: Was attendance at the Site Visit held at Charleston AFB last week Mandatory, and a requirement to make an offer?

ANSWER: No, attendance was not mandatory nor was it a requirement to make an offer.

2. QUESTION: Is it the intention of the Government for the rubber removal process identified as R1, Rubber Removal Chemical to be “solely” by the chemical/detergent method without the use of high pressure water or water blasting.

ANSWER: If pressurized water is used as part of chemical method, pressures above 2,000 psi shall not be permitted, unless demonstrated to be required due to the chemical method not resulting in an acceptable level of removal as determined by the Contracting Officer’s Representative on a case-by-case basis.

3. QUESTION: The requirement suggests that the chemical method of rubber removal would be utilized and high pressure water would not under R1. The chemical method of rubber removal does not use water pressures above that found at home. Please confirm if the Government’s definition of high pressure water is water pressures above 80 psi?

ANSWER: If pressurized water is used as part of chemical method, pressures above 2,000 psi shall not be permitted unless demonstrated to be required due to the chemical method not resulting in an acceptable level of removal as determined by the Contracting Officer’s Representative on a case-by-case

4. QUESTION: Will high pressure water (pressures above 80 psi) be allowed for any phase of cleaning including rinsing under R1.

ANSWER: If pressurized water is used as part of chemical method, pressures above 2,000 psi shall not be permitted unless demonstrated to be required due to the chemical method not resulting in an acceptable level of removal as determined by the Contracting Officer’s Representative on a case-by-case

5. QUESTION: Will the Government allow the Contractor to claim they are using the “detergent method” if they use a combination of high pressure water and a detergent?

ANSWER: If pressurized water is used as part of chemical method, pressures above 2,000 psi shall not be permitted unless demonstrated to be required due to the chemical method not resulting in an acceptable level of removal as determined by the Contracting Officer’s Representative on a case-by-case

6. QUESTION: For the rubber removal quantities identified in the price schedule, please provide the expected number of mobilizations for Charleston AFB and the number of mobilizations for North Field.

ANSWER: No more than 4 total mobilizations per year are expected, with no more than 2 expected at North Field. Historically there have been an average of 4 mobilizations for most Delivery Orders, but this may vary depending on runway usage and mission requirements.

7. QUESTION: Please provide the expected rubber removal quantities for each by location and mobilization.

ANSWER: Task Order quantities vary depending on runway usage and mission requirements. Task Order size limits are specified in 52.216-19 Order Limitations. 1995-10 for this solicitation. Historical Task Order magnitude is described in another answer.

8. QUESTION: Paint removal is normally priced per SF. Item P1 quantifies Paint Removal as a price per LF. If the Unit of Measure is Linear Foot, what is the width of the line used for pricing this item?

ANSWER: 12”

9. QUESTION: For Item P5, Layout of Airfield Markings, is it the intent of the Government to pay for markings laid out by registered surveyors or markings simply measured off existing airfield markings?

ANSWER: Layout of markings does not specifically require a registered surveyor provided it meets Task Order requirements.

10. QUESTION: For Item P-46, 2” Letters, please describe the scope of work intended and the number of locations where these letter are to be installed.

ANSWER: Although locations and application could vary, an example would be for refreshing individual letters in the word ‘RESTRICTED AREA’ for restricted area warnings. See detail below.

11. QUESTION: For Item T3 Flagman, please confirm if 80 MAN are 80 Man Hours.

ANSWER: Unit for item T3 is Man-Hours.

12. QUESTION: Please confirm one individual may simultaneously serve as Superintendent, Site Safety Health Officer (SSHO) and Quality Control Manager (QCM) on each delivery order.

ANSWER: Per SOW 3.2.2, the Contractor’s Project Superintendent (PS) can be the Contractor’s Contract Manager (CM), but cannot be the Contractor’s Quality Control Manager (QCM) or Contractor’s Safety Manager (SM). However, the SM is not prohibited from also performing as the

QCM.

13. QUESTION: May one individual supervise multiple simultaneous delivery orders?

ANSWER: Yes, provided they can effectively provide on-site daily supervision of active work for both Task Orders.

14. QUESTION: It is our understanding that a similar IDIQ contract has been in place for the last 5 years.

Can the government provide basic information regarding the work done under this contract (i.e. how many delivery orders were awarded each year? What was the average size of each delivery order? etc.).

ANSWER: Previous Task Order magnitude and number is not an assurance or indication of future work on this contract, however, See below link for publicly available award data on Task Order:

https://www.usaspending.gov/award/CONT_IDV_FA441816D0009_9700

15. QUESTION: Will a separate set of preconstruction submittals (Quality Control Plan, Accident Prevention Plan, and Environmental Protection Plan) be required for submission prior to the start of each delivery order?

ANSWER: If the original submitted plans sufficiently address all of the work to be accomplished on the Task Order as determined by the Contracting Officers Representative, additional plans shall not be required.

16. QUESTION: Per SOW Section 17.1 Standard Working Hours: “Standard Working Hours are from 0730 to 1630.” During the site visit, it was mentioned that due to demand on the Runway’s, work is typically done at night. Please confirm working hours to be expected on this contract.

ANSWER: See SOW 17.1 for standard working hours that apply to North Field (NAAF), and SOW

17.2 for standard working hours that apply to the Joint Base Charleston Air Base. Slight deviations (+/- 2 hours) in times may occur based on mission requirements but total number of hours shall remain the same on average.

17. QUESTION: Note, on other bases, we have been told to treat any rubber generated from rubber removal projects as Hazardous Waste. In the past, we have had to separate the rubber into a base-supplied dumpster and then have the waste removed from site by base environmental (at a cost). Please provide the standard procedure for both locations for removal of rubber waste. Our intention would otherwise be to treat the water used for rubber removal as storm water and dispose in an inlet and then dispose of the rubber waste as regular waste offsite.

ANSWER: Water from the water blasting removal process that is leftover or filtered from the rubber to remove any rubber particles, and water runoff from the cleaning process, must be directed away from storm drainage areas, and should not cause erosion. Water collected during rubber separation shall not be allowed to flow into nearby storm drains or cause erosion.

Materials collected during the removal process shall be disposed of offsite by the contractor. Contractor shall submit a landfill approval letter from landfill accepting materials.

Chemicals used in the chemical rubber removal process shall be non-toxic and biodegradable.

After the contract is awarded, the contractor shall provide to the government the following; 1) a list of chemicals used to comply with this contract, 2) SDS’s for each chemical, 3) the container size being purchased, and 4) the number of containers being purchased or that were purchased for the rubber removal evolution.

18. QUESTION: Please provide the make/model of runway lights.

ANSWER: Runway lights were designed and installed in compliance w/ UFC 3-535-01/UFC 3-535-02.

19. QUESTION: In certain instances, it is more time efficient to remove existing runway paint with grinding method instead of chemical or water blasting. Will this method be an acceptable alternate for smaller areas?

ANSWER: This can be considered as an alternative if it is demonstrated to be required due to the chemical or water blasting method not resulting in an acceptable level of removal as determined by the Contracting Officer’s Representative on a case-by-case basis.

20. QUESTION: Specification Section 32 01 19.61 paragraph 1.3.2 requires a “test section” be completed prior to cleaning and sealing joints for the remainder of the project. Will this be required on each delivery order requiring joint repair? How long will the test section be required to sit/cure before government inspection?

ANSWER: For joint seal, a test section is required for each Task Order requiring joint seal unless it is determined to be essentially the same pavement, product, conditions, and application as a previously approved test section. There is not a minimum required cure time before government inspection.

Approval of test section by government does not relieve contractor from responsibility for final installation meeting all contractual requirements.

21. QUESTION: Does the government have a preferred product for joint sealant/replacement?

ANSWER: No

22. QUESTION: During the site visit it was mentioned that an Addendum would be released including specific verbiage for the expected percentage of rubber removal. Please specify the expectation of paint removal. Will this differ when an area is being re-painted vs. complete removal?

ANSWER: See revised specification 32 01 11.51, dated 8/2021.

23. QUESTION: Can Prime Contractor rep escort subcontractor personnel onto the runway or will each individual be required to have runway access?

ANSWER: Drivers of vehicles will be required to obtain Airfield Drivers Licenses through the airfield management office.
