AMENDMENT 0001

Solicitation 140FS126Q0171 Merced NWR - Deep Well Repair and Rehabilitation

Item Amended Information Solicitation Number 140FS126Q0171 Amendment Number 0001 Original Posted Date August 21, 2026 Acquisition Status Unrestricted - all responsible business concerns may submit a quotation Site Visit September 15, 2026, 9:00 a.m. Pacific Time Questions Due September 16, 2026, 12:00 p.m. Pacific Time Revised Quote Due September 18, 2026, 12:00 p.m. Pacific Time Submission Email to oscar_orozco@ios.doi.gov Place of Performance Merced National Wildlife Refuge, 7430 W. Sandy Mush Road, Merced, CA 95341

1. Purpose of Amendment Amendment 0001 revises Solicitation 140FS126Q0171 to place all quoters on a common pricing basis after the Government determined that the extent of certain repairs cannot reasonably be known until diagnostic inspection and testing are completed. The amendment also changes the acquisition from a Total Small Business Set-Aside to unrestricted competition and establishes a scheduled site visit.

The revised structure uses firm-fixed-price (FFP) base CLINs for diagnostic and known repair work and separately priced FFP optional repair CLINs for foreseeable repairs. There is no time-and-materials, labor-hour, cost-reimbursement, or generic repair allowance.

2. Changes Made by Amendment 0001

• Set-Aside: The Total Small Business Set-Aside is removed. The solicitation is unrestricted. All responsible business concerns may submit a quotation.

• Site Visit: September 15, 2026, at 9:00 a.m. Pacific Time at the Merced National Wildlife Refuge. Prospective quoters need not confirm attendance. A sign in sheet will be provided on the day of the site visit.

• Questions: Due September 16, 2026, at 12:00 p.m. Pacific Time.

• Quote Deadline: Extended to September 18, 2026, at 12:00 p.m. Pacific Time.

• Pricing: The original quotation schedule is replaced in its entirety by Attachment 1. Quoters shall price every base and optional repair CLIN.

• SOW: The original Statement of Work is replaced in its entirety by Attachment 2.

• Options: Optional Repair CLINs 0010-0018 are separately priced FFP options. They may be exercised only by written Contracting Officer modification after applicable diagnostics establish the repair is required.

• 100-Amp Requirement: P18 is confirmed as a 100-amp electrical service replacement. Attachment 2 and CLIN

0009 are revised accordingly.

• Wage Determination: The Service Contract Labor Standards wage determination incorporated with the original solicitation remains applicable and is not reissued with this amendment.

• Revised Quotations: All quoters wishing to remain under consideration shall submit a revised quotation based on the solicitation as amended and acknowledge Amendment 0001.

3. Provisions and Clauses Changed by This Amendment Only the following provision and option clause are added by Amendment 0001. All other provisions and clauses in the original solicitation remain unchanged except that the small-business set-aside provision is no longer applicable because the solicitation is unrestricted.

• 52.217-5, Evaluation of Options - incorporated by reference for evaluation of Optional Repair CLINs 0010-0018.

• OPTION FOR SEPARATELY PRICED REPAIR SERVICES - OPTIONAL REPAIR CLINS 0010-0018 (Tailored)

- incorporated in full text below.

52.219-6, Notice of Total Small Business Set-Aside, is deleted from the solicitation as a result of the unrestricted acquisition status.

OPTION FOR SEPARATELY PRICED REPAIR SERVICES - OPTIONAL REPAIR CLINS 0010-0018 (TAILORED)

(a) The Government may exercise one or more Optional Repair CLINs 0010 through 0018, independently and at the firm-fixed prices established at contract award.

(b) An optional repair CLIN may be exercised only when the applicable diagnostic work identifies the repair as necessary, funds are available, the Contracting Officer determines exercise is in the Government's best interest, and the Contracting Officer issues written notice exercising the applicable option.

(c) Exercise of one optional repair CLIN does not require exercise of any other optional repair CLIN.

(d) The Government may exercise Optional Repair CLINs 0010 through 0018 by written contract modification issued by the Contracting Officer no later than October 31, 2026.

(e) The Contractor shall not begin performance of an optional repair CLIN until that CLIN has been exercised in writing by the Contracting Officer. Direction, recommendations, requests, or communications from Government technical personnel do not exercise an option or authorize additional work.

(f) Upon exercise, the applicable optional repair CLIN shall be performed at the firm-fixed price established at contract award. The option price includes all labor, supervision, materials, equipment, transportation, removal, installation, testing, commissioning, documentation, overhead, profit, and other costs necessary to complete the repair described by the applicable CLIN and SOW.

(g) The Government is under no obligation to exercise any optional repair CLIN. Evaluation of optional repair CLINs for award does not obligate the Government to exercise any option.

(h) Repair conditions not within the scope of a base CLIN or Optional Repair CLIN 0010 through 0018 are not authorized by this clause and shall not be performed without separate written contractual authorization from the Contracting Officer.

(End of Clause)
