The purpose of this amendment is to respond to vendor questions (See continuation pages).

All other terms and conditions remain the same and unchanged.

1. Missing 52.212-3 / 52.212-5 | SF1449 Blocks 27a/27b, PDF page 1 | Blocks 27a and 27b say FAR 52.212-3 and 52.212-5 are attached, but they are not in the posted solicitation.

Please post them, or confirm that offerors may rely on their SAM.gov representations and certifications (FAR 52.204-19) and indicate which 52.212-5 clauses apply. Included. FAR 52.212-3 and 52.212-5 are intended to be included with the solicitation. Offerors should complete the applicable representations and certifications in SAM.gov. The Government will identify the applicable FAR 52.212-5 clauses in the solicitation documents or an amendment; FAR 52.204-19 does not itself identify those clauses.

2. Buy American / country of origin | Section 3 Clauses, PDF page 5 | The SKC 375-0550N is manufactured in the United Kingdom according to SKC's published price list. Since the requirement is brand name only, please confirm that this foreign-origin end product is acceptable, and whether FAR 52.225-1 (Buy American) or another trade clause applies.

The required item is SKC Inc. Chek-Mate Flowmeter, Part Number 375-0550N, as specified in the solicitation.

3. Invoicing instructions | SF1449 Blocks 18a/18b, PDF page 1 | Block 18b references an addendum for invoice submission, but no addendum is posted. Please confirm the invoicing method (for example, Treasury IPP / DOL Quickpay) and payment office.

Included. The solicitation should provide the applicable invoice submission instructions and identify the payment office. The current document does not specify Treasury IPP, DOL Quickpay, or another invoicing system; these details should be confirmed in an addendum or by the Contracting Officer.

4. Warranty : Section 1 Product Specifications, page 3 | The manufacturer's standard one-year warranty is included in the unit price at no additional charge. Is the standard manufacturer warranty acceptable, or must the quote exclude any warranty? – Standard manufacturer warranty is acceptable at no additional cost. The solicitation states that MSHA will perform its own calibrations and does not require a separately priced warranty.

The standard warranty may accompany the equipment, but no additional warranty charge should be included.

5. Split delivery and partial shipments | Shipping/Delivery, PDF page 4 | Please confirm that shipments direct to the five listed MSHA sites (Dallas 5, Norton 20, Beckley 2, Morgantown 6, Warrendale 20) are acceptable and that partial shipments within the 30-day window are acceptable. –Shipments are to be delivered directly to the five MSHA locations in the quantities listed in the solicitation. All 53 units must be delivered in full within 30 days after receipt of order (ARO). Partial shipments may be made only if they do not prevent complete delivery to each required location within that period; the solicitation does not expressly authorize partial deliveries..

6. Quote format | Section 4 Instructions, PDF page 7 | Besides the completed SF1449 (blocks 12, 17, 23, 24, 30) and a price/validity statement, is a separate technical submission (for example, the SKC product data sheet) required to show technical acceptability? – Yes. Please include a separate technical submission, such as the SKC manufacturer product data sheet, identifying Part Number 375-0550N and demonstrating compliance with the product specifications. Include the completed SF1449, pricing, and a statement that the quote remains valid for 90 days, as required by the solicitation.

7. Does the Nonmanufacturer Rule apply to this procurement, considering its anticipated contract value? Yes. The Nonmanufacturer Rule applies to this procurement. As this solicitation is a 100% small-business set-aside, contractors must comply with the applicable Small Business Administration (SBA) requirements under 13 CFR 121.406.

Offerors are responsible for ensuring their quotations meet the applicable small-business eligibility and Nonmanufacturer Rule requirements.

8. If applicable, has an SBA class waiver or individual waiver been granted for the specified SKC product? No. An SBA class waiver or individual waiver has not been granted for the specified SKC Chek-Mate Flowmeter, Part Number 375-0550N. Therefore, offerors must comply with the applicable Nonmanufacturer Rule requirements when submitting their quotations. The Government has not identified an approved waiver for this procurement.

9. May a qualified small-business reseller supply the exact manufacturer-specified product through an authorized distributor? The Government does not control or select the subcontractors, distributors, or suppliers utilized by the prime contractor. Contractors are responsible for determining their own supply arrangements and ensuring that the products provided meet all solicitation requirements.

However, the use of an authorized distributor does not exempt the prime contractor from applicable small-business requirements, including the Nonmanufacturer Rule. The contractor remains responsible for compliance with all applicable contract terms and federal regulations.

(End of Clause)

2952.209-70 Organizational Conflict of Interest Clause - OCI-1 Exclusion From Future Agency Contracts. (Deviation MAR 2026)

This clause supplements the FAR provisions on organizational conflicts of interest, located at FAR subpart 9.500 and should be read in conjunction with these provisions. To the extent there is any inconsistency or confusion between the two provisions, the FAR provision controls.

(a) Work under this contract may create a future organizational conflict of interest (OCI) that could prohibit the contractor from competing for, or being awarded, future government contracts.

The following examples illustrate situations in which organizational conflicts of interest may arise. They are not all inclusive, but will be used by the contracting officer as general guidance in individual contract situations:

(1) Unequal Access to Information. The performance of this contract may provide access to “nonpublic information,” which could provide the contractor an unfair competitive advantage in later solicitations or competitions for other DOL contracts. Such an advantage could be perceived as unfair by a competing vendor who is not given similar access to the same nonpublic information that is related to the future procurement action. If you, as a contractor, in performing this contract, obtain nonpublic information that is relevant to a future procurement action, you may be required to submit and negotiate an acceptable mitigation plan prior to being deemed eligible to compete on the future action. Alternatively, the “nonpublic information” may be provided to all offerors.

(2) Biased Ground Rules. Your contract with DOL may have, in some fashion, established important “ground rules” for another DOL procurement, in which you may desire to be a competitor. For example, this contract may involve you drafting the statement of work, specifications, or evaluation criteria for a future DOL procurement. The primary concern, in any such situation, is that any such firm could skew the competition, whether intentionally or not, or be perceived as having skewed the competition, in its own favor. If the requirements of this DOL contract anticipate the contractor may be placed in a position to establish important ground rules, including but not limited to those described herein, the contractor may be precluded from competing in the related action or, if possible, may be required to submit and negotiate an acceptable mitigation plan.

(3) Impaired Objectivity. The performance of this contract may result in the contractor being placed in a situation where it is able, or required, to provide assessment and evaluation findings concerning itself, another business division, a subsidiary or affiliate, or other entity with which it has a significant financial relationship.

The concern in this case is that the contractor’s ability to render impartial advice to DOL could appear to be undermined by the contractor’s financial or other business relationship to the entity whose work product is being assessed or evaluated. In these situations, a “walling off” of lines of communication between entities or divisions may be acceptable, but it also may not be sufficient to remove the perception that the objectivity of the contractor has been tainted. If the requirements of the DOL procurement indicate that a contractor may be placed in a position to provide evaluations and assessments of itself or other entities with which it has a significant financial relationship, the affected contractor should notify DOL immediately. The contractor may also be required to provide a mitigation plan that includes recusal by the contractor from one of the affected contracts. Such recusal might include divestiture of the work to a third party.

(b) In order to prevent a future OCI of any kind, the contractor must be subject to the following restrictions:

(1) The contractor may be excluded from competition for, or award of, any government contracts as to which, in the course of performing another contract, the contractor has received nonpublic and competitively relevant information before such information has been made generally available to other persons or firms.

(2) The contractor may be excluded from competition for, or award of, any government contract for which the contractor actually assisted or participated in the development of specifications or statements of work.

(3) The contractor may be excluded from competition for or award of, any government contract which calls for it to evaluate itself, any affiliate, or any products or services produced or performed thereby.

(4) The contractor may be excluded from competition for, or award of, any government contract calling for the production or performance of any product or service for which the contractor participated in the development of requirements or definitions pursuant to another contract.

(5) This clause shall not exclude the contractor from performing work under any modification to this contract or from competing for award of any future contract for work that is the same or similar to work performed under this contract, so long as the conditions above are not present. This clause does not prohibit an incumbent from competing on a follow-on competition, but the contracting officer may require a mitigation plan or other steps as needed to ensure that there has not been an unequal access to nonpublic competitively sensitive information.

(c) The term “contractor” as used in this clause, includes any person, firm or corporation that owns or controls, or is owned or controlled by, the contractor. The term also includes the corporate officers of the contractor.

(d) The agency may in its sole discretion, waive any provisions of this clause if deemed in the best interest of the Government. The exclusions contained in this clause will apply for the duration of this contract and for three (3) years after completion and acceptance of all work performed hereunder, or such other period as the contracting officer directs.

(e) If any provision of this clause excludes the contractor from competition for, or award of any contract, the contractor must not be permitted to serve as a subcontractor, at any tier, on such contract. This clause must be incorporated into any subcontracts or consultant agreements awarded under this contract unless the contracting officer determines otherwise.

(End of Clause)

2952.243-70 Contractor’s Obligation to Notify the Contracting Officer of a Request to Change the Contract Scope (Contractor’s Obligation Clause) (Deviation MAR 2026)

(a) Except for changes identified in writing and signed by the contracting officer, the contractor is required to notify, within five working days of receipt or knowledge, any request for changes to this contract (including actions, inactions, and written or oral communications) that the contractor regards as exceeding the scope of the contract. On the basis of the most accurate information available to the contractor, the notice must state:

(1) The date, nature, and circumstances of the conduct regarded as a change in scope;

(2) The name, function, and activity of each Government employee and contractor official or employee involved in, or knowledgeable about, such conduct; and

(3) The identification of any documents and substance of any oral communication involved in such conduct.

(b) Following submission of this notice, the contractor must continue performance in accordance with the contract terms and conditions, unless notified otherwise by the contracting officer.

(c) The contracting officer must promptly, within 5 business days after receipt of notice from the contractor, respond to the notice in writing. In responding, the contracting officer must either:

(1) Confirm that the contractor’s notice identifies a change in the scope of the contract and directs the contractor to stop work, completely or in part, in accordance with the Stop Work provisions of the contract;

(2) Deny that the contractor’s notice identifies a change in scope and instruct the contractor to continue performance under the contract; or

(3) In the event the contractor’s notice does not provide sufficient information to make a decision, advise the contractor what additional information is required, and establish the date by which it should be furnished and the date thereafter by which the Government will respond.

2952.242-71 DOL Mandatory Training Requirements for Contractor Employees (Deviation MAR 2026)

(a) Where required and applicable, contractor employees, including employees of subcontractors at any tier, must complete any DOL designated and hosted training, that the Contracting Officer's Representative (COR) identifies as mandatory.

Training must be completed in a timeframe specified by the COR.

(b) Time spent on training must be counted as regular hours worked.

(c) The contractor must ensure this clause is incorporated in all subcontracts, at any tier.

(End of Clause)

2952.242-70 Access to Contractor Business Systems (Deviation MAR 2026)

The contractor must, upon request, provide to the Government, access to covered contractor systems associated with the execution and performance of this requirement to meet audits, reviews, security requirements, and Office of Inspector General requests.
