L. Period of Performance and Contract Structure This contract consists of a Base Year plus four (4) One-Year Option Periods (Base + 4). Each period of performance (base and each exercised option year) includes annual inspections and access to the Maintenance Rider described in Section M. The below table clarifies what services are expected during each option year.

M. Maintenance Rider — Urgent and Non-Urgent Repairs The requirement includes a Time-and-Material (T&M) line item, under a single CLIN per period of performance (see Section L) for both Urgent and Non-Urgent Repairs, for the water system equipment listed in Section D. This line item shall not be used for the annual inspection deliverable or any re-work/correction due to the Contractor's deficiencies on that scheduled item.

The labor rate shall be a flat, hourly rate to cover the entire effort and shall be burdened consistent with the direct/non-production labor structure below:

· Direct production labor hour functions only. Direct production is work performed by a qualified craftsman directly related to the alteration, modification, or repair of the identified equipment, including pump service technicians, water control systems technicians, chlorination systems technicians, and/or skilled or general laborers.

· Non-production labor hours shall be priced into the burdened rate for production labor, and include functions such as testing, quality assurance, engineering support, planning, estimating, material handling, set-up, general labor, cleaning, transportation, and supervision.

· This section also applies to any Subcontractor labor hours used. Markup material rates may not be used on subcontractor labor hours.

Urgent Repairs: Upon COR notification of an urgent repair, the Contractor shall respond within twenty-four (24) hours to resolve.

· No travel reimbursement is authorized. Labor hours are based on time of check-in/check-out of each technician at the facility, which is mandatory.

· For urgent repairs specifically, Not to Exceed (NTE) for labor hours is two (2) hours per event unless approved by the CO or COR in advance. If approval was not received in advance, the Contractor shall only charge two (2) hours on invoicing. There is no NTE for materials.

· These statements are not to be construed as the Contractor's approval to exceed the line item ceiling price.

Non-Urgent Repairs: Upon request and approval of the COR, the Contractor shall perform non-urgent repairs to the equipment listed in Section D, following applicable codes cited in Section K. The COR will provide an initial Condition Found Report (CFR), in Appendix A, with general details for the Contractor to complete.

· The COR will communicate whether normal and/or after-hours work is required for each request. See Section G for hours.

· If normal work hours are requested and the Contractor chooses to begin work before or after hours, only the normal work hour rate shall be invoiced. Advance COR approval is required to use the after-hours rate.

· No travel reimbursement is authorized. Labor hours are based on time of check-in/check-out of each technician at the facility, which is mandatory.

Upon receipt of a CFR, the Contractor shall submit the following to the COR before work is approved to begin:

· Contractor information, including Contractor POC and contact information.

· Location and equipment information for the deficiency.

· Information explaining the deficiency.

· Recommendation for repair, replacement, or no action.

· Detailed scope breakdown, including labor (direct production hours by category, straight time/overtime), materials (bill of materials with description, quantity, and source), and subcontractor involvement (individually identified, with a scope of work and confirmation that a quote has been obtained where applicable — no lump sums, including subcontractor lump sums). Pricing for labor, materials, and subcontractor costs shall be applied per the rates and terms established in the negotiated contract and is not required to be estimated in dollar terms within the CFR itself.

· Name and signature of the Contractor employee submitting the CFR to the Government.

CFR information provided directly to the Government from a subcontractor will not be considered and constitutes a contract discrepancy. After approval, the Contractor shall respond within 24 hours when parts are on hand to fix the found condition. If parts are not on hand, the Contractor shall respond within 48 hours unless otherwise approved by the COR. If actual work exceeds the CFR estimate by more than 5%, the Contractor shall notify and receive approval from the COR to continue.

Invoicing Procedures The Contractor shall submit documentation to the COR showing a completed CFR (non-urgent requirements only) and a complete invoice breakdown of work actually performed, including task description, location, day/time of hours worked, number of hours worked, normal/after-hours rate, itemized materials with markup, and subcontractor breakdown with markup as applicable. All material pricing must be supported with separate receipt copies. The Contractor is responsible for tracking and certifying that all labor hours are true and correct at submission.

The Government has the right to reject any incomplete, inaccurate, or lump-sum labor/material pricing breakdowns and to audit the Contractor's submission. The Contractor shall provide any necessary corrections within 10 business days and resubmit. In the event of a lack of consensus on documentation that cannot be resolved between the COR and Contractor, the Contracting Officer shall review all documentation and make the final decision.

The Contractor shall not exceed the ceiling price on this CLIN except at its own risk, and shall monitor T&M usage and report to the COR when additional funding may be required for future urgent and non-urgent repairs.

N. Deliverables

· Written condition assessment following each annual inspection, addressing each item in Section D.

· Photographs of the condition of each inspected system/component.

· List of corrective actions and recommendations following each inspection.

· All inspection and repair documentation provided to the COR for provision to the current water system operator (Valley Water Services).

O. Water System Operability The Contractor shall ensure the water system remains operable at all times except while being tested or repaired, consistent with the shutdown notification requirement in Section F. The Contractor shall coordinate with the COR to confirm the backup City of Walla Walla connection is available and adequate to cover the duration of any planned shutdown of well, pump, or water tower equipment.

P. Damage to Water System Any damage to the water system or associated equipment caused by the Contractor during inspection, testing, or repair shall be repaired by the Contractor at no additional cost to the Government. The Contractor shall be liable for all costs associated with such damage. At its discretion, the Government may have representatives present to witness any or all such work.
