SUBJECT EXPRESSION OF INTEREST (EOI) / REQUEST FOR INFORMATION (RFI)

NO. PP-001 DATED: JULY 13, 2026 FOR THE PROVISION OF FIRE SUPPRESSION

SERVICES IS HEREBY AMENDED AS FOLLOWS:

This Amendment 001 serves to provide response to questions received as follows:

1. Question 1: Can you clarify whether this Subcontract will require the successful Offeror to absorb existing personnel performing the services or does this Subcontract provide supplemental support for fire protection services?

MSTS Response to Question 1: No, this subcontract does not require the successful Offeror to absorb existing personnel. MSTS personnel will remain employees of MSTS. The subcontractor is expected to utilize and manage their own qualified personnel to independently perform the scope of work described in the Statement of Work (SOW).

2. Question 2: Security and Site Access - Can MSTS provide additional details regarding the security and site-access requirements for contractor personnel across the three contract pools? Specifically, will security clearances be required, and may uncleared personnel perform work under escort when appropriate?

MSTS Response to Question 2: Detailed security and site-access requirements will be outlined in Exhibit F (a representative sample is attached to this Amendment 001). Please note that Exhibit F is provided as a sample only and may be subject to change prior to solicitation and subcontract award.

Regarding personnel clearances and escorts:

Security Clearances: Active personnel security clearances are not anticipated to be required for the

Subcontractor's work.

Sensitive Areas (SCIF/VTR): Uncleared Subcontractor personnel will strictly not be allowed entry into

Sensitive Compartmented Information Facilities (SCIFs) or Vault-Type Rooms (VTRs).

Limited Areas: Uncleared personnel may be granted access to perform work within other designated

Limited Areas (LAs), provided they are accompanied by an approved, cleared escort at all times.

3. Question 3: IDIQ Minimums and Maximums - For the Scope 2 Architecture/Engineering (A/E) and Scope 3 Design-Build (D-B) IDIQ Blanket Master Agreements, what are the anticipated minimum guaranteed award amounts and maximum contract ceilings over the five-year period?

MSTS Response to Question 3: It is anticipated that the maximum amounts of Task Orders for Scope 2 and Scope 3 will not exceed $500K each per year. The maximum contract ceiling amount for the five-year period of this Subcontract is anticipated to be $5M.

4. Question 4: Task-Order Pricing - For Phase IV Construction Support, does MSTS anticipate awarding task orders on a firm-fixed-price basis for each project, or using Time-and-Materials or Labor-Hour rates to accommodate unpredictable construction schedules and field change requests?

MSTS Response to Question 4: MSTS intends for Phase IV, Construction Support, to be awarded on a Firm-Fixed-Price (FFP) basis for each requested project. To accommodate potential variances in construction schedules and the volume of field requests, MSTS intends to define clear boundaries and baseline assumptions in the scope of work for activities that involve varying levels of effort.

5. Question 5: Fire-System Information - Will the forthcoming RFP provide system details—including manufacturer, model, age, and quantity—for all fire systems included in the project’s scope?

MSTS Response to Question 5: Complete technical specifications for the fire systems are not currently available for release. However, MSTS plans to conduct a site walk-down during the solicitation phase. This walk-down will provide Offerors with the opportunity to directly inspect the equipment and gather necessary system details, including manufacturer, model, age, and component quantities.

6. Question 6: Reference: Section 3, CLIN 001 – Scheduled Maintenance Activities

Will fire alarm monitoring (central station or proprietary supervising station service) be included in the IT&M scope, or is the scope limited to inspection, testing, and maintenance of the fire suppression, alarm and detection systems?

MSTS Response to Question 6: Monitoring of the fire alarm and detection system is not included in this scope of work.

7. Question 7: Reference: Section 3, A/E and FPE Design Services and Design-Build, Estimated Value

The estimated values for the A/E-FPE Design Services pool and the Design-Build pool are listed as To Be Determined. Can MSTS share historical annual spend, anticipated task order sizes, or the anticipated number of task orders per year to assist firms in assessing capacity and bonding capability?

MSTS Response to Question 7: Reference response to Question 3. MSTS anticipates approximately eight

(8) task orders to be released per year.

8. Question 8: Reference: Section 3, A/E and FPE Design Services and Design-Build, Proposed Structure

Will the IDIQ/BMA vehicles contemplated for the A/E-FPE Design Services and Design-Build pools be single-award or multiple-award?

MSTS Response to Question 8: Presently, MSTS intends to make a single award for the AE-FPE Design Services and Design-Build pools. However, MSTS reserves the right to make multiple awards if determined to be in the best interest of the program.

9. Question 9: Reference: Section 4, Section A, Contemplated NAICS Code

The contemplated NAICS code is 238210, Electrical Contractors and Other Wiring Installation Contractors ($19,000,000.00 size standard). Fire suppression IT&M and design-build work is more typically classified under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and A/E-FPE design services under NAICS 541330 (Engineering Services).

Will a single NAICS code apply to all three pools, or will each pool carry its own NAICS code and corresponding size standard? This determination materially affects small business eligibility and compliance with limitations on subcontracting.

MSTS Response to Question 9: In the event the work is allocated under three (3) separate awards, each award will be assigned its own NAICS representing the majority effort of the work requested.

10. Question 10: Reference: Section 4, Section B, Barriers to Competition

What personnel security requirements will apply (e.g., DOE Q or L clearances, HSPD-12 badging, background investigations, U.S. citizenship)? What is the typical badging or clearance processing timeline, and may work commence under escort while clearances are in process?

MSTS Response to Question 10: Reference response to Question 2.

11. Question 11: Reference: Section 4, Section B, Bonding Optimization

What payment and performance bonding requirements and thresholds will apply to the Design-Build pool and to any construction-type work performed under the other pools?

MSTS Response to Question 11: Payment and performance bonding requirements will be applied on a Task-Order-by-Task-Order (or Subcontract-by-Subcontract) basis.

Specifically, the following thresholds and requirements will apply:

a) For Construction and Design-Build work valued over $150,000: In accordance with FAR 28.102-1(a)

(implementing 40 U.S.C. chapter 31, subchapter III, Bonds; formerly known as the Miller Act), performance and payment bonds is a mandatory requirement. The standard requirement is:

i. A performance bond equal to 100% of the original Subcontract/Task Order price.

ii. A payment bond equal to 100% of the Subcontract/Task Order price.

iii. MSTS may require additional performance bond protection when the subcontract/Task Order price is increased. The increase in protection shall generally equal 100 percent of the increase in subcontract/Task Order price.

b) For Construction work valued between $35,000 and $150,000: MSTS may use either a Payment Bond

(original copy), or an Irrevocable Letter of Credit (ILC):

i. For the Payment Bond:

The penal amount of payment bonds shall be 100 percent of the original subcontract price.

MSTS may require additional performance bond protection when the subcontract price is increased. The increase in protection shall generally equal 100 percent of the increase in subcontract price.

c) For Non-Construction Pools (e.g., A/E-FPE Design Services): Generally, performance and payment bonds are not required for other-than-construction services, pursuant to FAR 28.103-1. However, MSTS reserves the right to require bonds on any specific Subcontract/Task Order exceeding the simplified acquisition threshold ($350,000) if it is determined to be in the best interest of MSTS and the Government to protect assets or property.

The specific bonding requirements, forms, and due dates will be clearly articulated in each individual Request for Proposal (RFP) or Request for Quote (RFQ) issued under the respective pools.

12. Question 12: Reference: Section 3, IT&M Services, CLIN 001 – Scheduled Maintenance Activities

CLINs 001 through 003, reference the NNSS (Mercury) facility; however, all frequency-based tasks (weekly, monthly, quarterly, semi-annual, annual, and five-year IT&M) list only the NLV and RSL-N facilities. When the solicitation and scope of work is released, please clarify what scheduled IT&M work, if any, is required at the NNSS, and at what frequencies.

MSTS Response to Question 12: The frequencies described shall apply to the three locations. (i.e., NLV, RSL-N, and the NNSS).

13. Question 13: Reference: Section 3, CLIN 002 – Urgent Response to Abnormal Conditions; Section 4, Section A, Geographic Reach
