1305M226Q0181 HML Chiller Maintenance - Questions/Answers

1. During these inspections, the company will troubleshoot, repair, or replace controls and primary pumps as necessary. Is it expected that the contract includes controls and primary pumps repairs or replacements?

No. This sentence is incorrect and should be revised. The base preventive maintenance price includes inspection, troubleshooting, operational testing, and deficiency reporting for the controls and primary pumps. Repair or replacement is corrective work and requires a separate quote and prior written authorization from the Contracting Officer, unless the item is expressly listed as a preventive maintenance consumable. See the response to Question 2.

2. Is the intent of the contract to include minor and major repairs? What is considered minor and major repairs?

No. The base price includes only the preventive maintenance tasks expressly listed in the SOW, associated labor and tools, identified consumables, routine adjustments, reporting, and correction of deficiencies caused by the contractor's own performance or workmanship. Repair or replacement of failed or deteriorated equipment outside those tasks is corrective work and requires an itemized quote and prior written authorization from the Contracting Officer under the applicable NTE CLIN or contract modification. For classification only, a minor repair is limited work that does not require major disassembly or replacement of a major component. A major repair involves substantial disassembly, specialized labor or equipment, opening a refrigerant circuit, structural work, or repair or replacement of a major component. Neither classification makes corrective work part of the base price. The two H-Wing air-cooled chillers, the NMR air-cooled chiller, and the 10-ton AAON rooftop unit serving F-Wing have been non-operational for an extended period and are being replaced under a separate active contract. The malfunctioning IT Server Room Liebert split system, currently rated at 5 tons, is also being replaced under that contract with a like-kind 3-ton system. Installation of the replacement equipment is anticipated within approximately six months, subject to lead times. The base price does not include restoring or performing corrective repairs on the existing units.

Preventive maintenance for the replacements will begin after installation, startup, commissioning, and Government acceptance and will focus on proactive maintenance, condition monitoring, documentation, and preservation of manufacturer warranties. Warranty deficiencies shall be reported and coordinated with the installer or manufacturer.

3. This includes performing all minor and major repairs related to the scheduled maintenance services. Is the intent of the contract to include minor and major repairs? What is considered minor and major repairs?

See the response to Question 2. The quoted sentence shouldbe revised. The contractor shall perform the listed preventive maintenance tasks and correct deficiencies in its own work at no additional cost. Equipment repairs or replacements outside those tasks require a separate quote and prior written authorization from the Contracting Officer.

4. Deficiencies shall be corrected at no additional cost to the government. What repairs are to be included in the contract? What repairs are to be excluded from the contract?

This requirement applies only to deficiencies in the contractor's performance or workmanship.

Equipment deficiencies shall be documented and reported. Corrective repair or replacement is governed by the response to Question 2 and is not included in the base price unless expressly listed in the revised SOW.

5. Clean cooling tower fins and hot and cold-water basins once per year. Leak test and repair. 11) Cooling Tower Mechanical Inspection, Leak Testing, and Repairs. Are Cooling tower leak repairs included in the contract? Cooling tower fins are not typically manually cleaned due to risk of damage. This is often completed through the chemical treatment. Is the intent of the contract to include chemical water treatment for the cooling tower?

The base price includes the annual cooling-tower mechanical inspection, leak testing, and manufacturer-approved cleaning of the fill media and hot- and cold-water basins. The term "fins" should be revised to "fill media." Cooling-tower leak repairs, basin or structural repairs, and failed-component replacements are corrective work governed by Question 2. Chemical water treatment is not included and shall remain coordinated through the Government's separate water-treatment provider.

6. An annual Not-To-Exceed (NTE) allowance of $12,000 per contract year is established for major corrective repairs that are outside the routine preventive maintenance scope. Is the NTE annual allowance in addition to repairs that are included in the contract? $12,000 is fairly low for annual Major Repairs. What happens when the $12,000 limit is reached?

The $12,000 annual NTE allowance is separate from the base preventive maintenance price. It is a ceiling for corrective repairs the Government may authorize and is not guaranteed revenue. Each repair requires an itemized quote and prior written authorization from the Contracting Officer. Once the ceiling is reached, no additional repair work may proceed unless the Contracting Officer provides written authorization and, when required, adds funding or increases the ceiling by contract modification.

7. Major Corrective Repair Allowance (NTE) - Contractor shall submit a written repair quote before proceeding. Please clarify what repairs are to be included in the contract price. Please clarify what repairs are to be quoted outside of the contract price.

See the response to Question 2. The contract price includes the preventive maintenance tasks expressly listed in the SOW and routine incidental adjustments that require no replacement parts, significant added labor, or specialized corrective work. Failed-component repairs and replacements shall be quoted separately and may proceed only after written authorization from the Contracting Officer. Restoration of the four existing non-operational units is not included in the base price.

8. The opening section of the SOW states that emergency response must occur within four hours.

Other sections require a callback within 30 minutes and technician arrival within two hours. Please confirm the applicable on-site emergency response time.

The contractor shall acknowledge an emergency request by telephone or email within 30 minutes and have a qualified technician on site within four hours of the initial Government request. The conflicting two-hour requirement should be revised to four hours.

9. Please confirm whether the requirement is for two total scheduled visits annually, one annual shutdown inspection and one operational inspection, or two semiannual inspections in addition to the annual shutdown.

The requirement is for two total scheduled preventive maintenance visits per contract year: one annual shutdown inspection and one semiannual operational inspection. The annual shutdown inspection is one of the two visits, not an additional third visit. Annual tasks shall be completed during the annual visit; applicable operational checks shall be completed during the scheduled visits.

10. The SOW requires annual and semiannual oil analysis, oil and refrigerant-filter replacement, and also states that the chillers must be “oilless.” Please clarify which requirements apply to each listed chiller.

The two York YMC2 magnetic-bearing chillers are oil-free and do not require compressor oil analysis, oil replacement, or oil-filter replacement. The York YLAA air-cooled chillers and the AAON rooftop unit use sealed compressor and refrigerant circuits; routine oil analysis, oil changes, and external oil-filter replacement are not required unless specified by the applicable manufacturer for the installed unit. Because the H-Wing and NMR air-cooled chillers are being replaced, their final preventive maintenance requirements shall follow the accepted replacement models and warranty instructions. The three annual inline filters apply to the MSC Chillgard RT refrigerant-monitor sampling system, not to each chiller. Chiller refrigerant filter-driers shall be replaced only when required by the manufacturer or as part of separately authorized corrective work. The statement that all chillers must be "oilless" should be revised to apply only to the York YMC2 chillers.

11. Please confirm how offerors should price the $12,000 annual NTE major corrective-repair allowance. Should the full $12,000 be included in the quoted CLIN price, or will approved repairs be separately authorized and invoiced based on actual costs?

The full $12,000 shall not be included in the quoted price for CLIN 0001. The Government will fund a separate annual NTE corrective-repair CLIN. Approved repairs will be separately authorized and invoiced at the accepted quoted or actual cost, as applicable. Unused funds are not payable to the contractor.

12. If the $12,000 annual allowance is exhausted, please confirm whether additional mission-critical repairs will be handled through a contract modification or another written authorization from the Contracting Officer.

Once the annual NTE allowance is exhausted, the contractor shall not perform additional corrective repairs unless the Contracting Officer issues written authorization and, when required, modifies the contract to add funding or increase the ceiling. The TPOC/COR may recommend action but may not authorize additional cost or work beyond the funded scope.
