Questions & Answers-Amendment 03

1. . The Statement of Work calls for removing the two existing roof-mounted units and installing new ground-mounted units on concrete pads. Would the Government accept a quote to replace the existing rooftop units with new rooftop units that meet the specified capacity and efficiency requirements, keeping them in their current location on the roof?

Units at grade at this site would be exposed to dirt, sand and debris that can clog coils and shorten equipment life, while the existing rooftop location keeps them clear of that. If ground mounting is required, could you share the reason (for example roof structure, maintenance access, or something else) so we can price it correctly?

Response: Ground mounted units are required for this project. In the future we are planning on installing metal roofing onto both houses, so the roof mounted units would impact the coverage of the metal sheeting. Ground mounting would also allow for easier maintenance access.

2. Given the age of the buildings, could you please confirm whether any asbestos-containing materials or lead-based paint are present in Buildings 100 and 200?

Additionally, are there any existing hazardous material surveys or testing reports available for review? If these materials are present, please clarify whether any required testing, abatement, or special handling should be included in the contractor's scope of work.

Response: There is no report to provide, however, per Arizona Game and Fish Department, no hazardous materials were previously found.

3. The specifications mention metal ductwork, but the existing ductwork is flexible. Are we able to use flexible ductwork throughout the project, or does it need to be metal like the specifications say?

Response: Flexible ductwork similar in specification to the existing ductwork is permissible.

4. We'll bid the job per the specifications, but we'd also like to add a recommendation to upgrade the ductwork because we think it would improve the project. Should we bid it twice, once per spec and once with the recommendation?

Response: Offerors may propose an alternative approach as a separate quote submission.

5. In Amendment 2, question 11, I see that you're approving mini split installations. Does that mean they don't have to be made in the United States, or do they still need to meet the Buy American requirement

Response: Buy American is still applicable.

6. . Amendment 02, Questions and Answers, Response 4; Revised Statement of Work, Section 10, page 9. The Government's response to Question 4 establishes February 26, 2027, as the final completion date, while the revised Statement of Work issued under Amendment 02 continues to require completion by January 31, 2027. Please confirm the controlling final completion date.

Response: Final completion date is February 26, 2027. The Statement of Work is being updated and provided with Amendment 03.

7. Revised Statement of Work, Section 4, page 3; Section 5, Table 1.03, page 7. For a ducted replacement configuration, please confirm whether the required insulated metal ductwork entails replacing all existing supply and return distribution ductwork, or whether suitable existing distribution may be retained and modified. Table 1.03 estimates 600 LF, while Q&A response 11 separately permits qualifying ductless alternatives.

Response: If the existing system ductwork is determined to be suitable upon inspection, it can be used “as-is” and/or modified for this project.

8. Revised Statement of Work, Section 5, page 6; Table 1.03, page 7. Tables 1.01 and 1.02 give existing HVAC unit electrical nameplate ratings, but the building service and distribution-panel data is unknown. Can the government provide any available service/panel capacity information or assessment of their adequacy for replacement HVAC equipment?

Response: For Building 100, a 225-amp breaker panel is present. Pictures of the Building 100 panels and electrical equipment are attached below.

9. Revised Statement of Work, Section 5, page 6; Table 1.03, page 7. The SOW calls for new equipment connections and conditionally requires electrical components to meet modern standards if needed after pre-project inspection. For lump-sum bidding, please identify any panel, service, or distribution upgrades beyond the listed disconnects and wiring that must be included in the base price.

Response: Replacement of existing electrical panels and services is not expected for this project. Please refer to the previous question for specific panel models and existing electrical equipment.

10. Revised Statement of Work, Section 5, Existing HVAC Removal and Roof Repair, page 4.

The required roof repairs may expose concealed deterioration or damage that cannot be established before removal of the existing rooftop HVAC units. Should contractors limit their base pricing to the specified removal and roof restoration scope, with additional concealed repairs addressed through a contract modification, or must contractors include an allowance for additional roofing and structural repairs? If an allowance is required, Could the government establish its basis?

Response: If additional repairs outside the scope of the SOW do arise, a contract modification will be implemented.

11. Revised Statement of Work, Section 4, page 3; Section 5, Table 1.03, page 7. The new HVAC equipment locations are subject to Government approval, and the estimated quantities include 150 linear feet of HVAC piping and 30 linear feet of electrical wiring.

Please identify the anticipated installation locations for the two ground-mounted systems or establish the assumed routing distances contractors should use for lump-sum pricing before final equipment locations are approved.

Response: The anticipated locations for the ground mounted units will be on the sides of the buildings with the existing electrical panels. For Building 100, this will be the “northeast” side. For Building 200, this will be the “west” side. Provided quantities in the SOW are only estimates, so quotes should reflect the contractor’s expected quantities with these anticipated locations of the ground-mounted units.

12. Revised Statement of Work, Section 5, Existing HVAC Removal and Roof Repair, page 4;

Amendment 02 Questions and Answers, Response 10. The Government has indicated that Buildings 100 and 200 date from approximately the 1960s or 1970s. Can the government provide any available surveys or records identifying asbestos-containing materials, lead-based paint, or other regulated materials in the areas affected by HVAC removal, roofing, ductwork, and associated building modifications, or confirm that no such records are available?

Response: There is no report to provide, however, per Arizona Game and Fish Department, no hazardous materials were previously found.

13. Revised Statement of Work, Section 6, page 8; Figures 11-12, page 14. The Statement of Work indicates that a Government-owned telehandler will be available for contractor use. Please provide the telehandler's model and rated lifting capacity.

Response: The model number for the telehandler is TM 10-3930-660-10. A PDF manual for the telehandler can be found at https://www.liberatedmanuals.com/TM-10-3930-660- 10.pdf. The model has a rated lifting capacity of 6,000 lbs.

14. Revised Statement of Work, Section 6, page 8; Figures 11-12, page 14. The SOW states that a Government telehandler and backhoe will be available for contractor use. Please confirm whether the telehandler may be used for lifting and removing the existing rooftop https://www.liberatedmanuals.com/TM-10-3930-660-10.pdf

HVAC units, and identify any operational restrictions or lifting attachments the Government will require.

Response: The telehandler may be used to remove the existing HVAC units. Rigging and lift requirements will be based off OSHA standards and required procedures.

15. Revised Statement of Work, Sections 9 and 10, page 9. The SOW identifies nights, weekends, and holidays as non-duty hours and requires scheduling with a Government POC. Please state the permitted construction work hours, including whether work during non-duty hours is allowed with advance coordination.

Response: Typically, allowable working hours will be from 6:00 am to 5:00 pm. If construction work hours are required outside of this timeframe or during non-duty hours, it will be allowable upon advanced review and approval of the Contracting Officer or Contracting Officer’s Representative.

16. Does BOR require the new ground-mounted HVAC equipment to be installed on the side of each building opposite the existing electrical panel, or may the final location be determined based on field conditions and BOR approval?

Response: The anticipated locations for the ground mounted units will be on the sides of the buildings with the existing electrical panels. For Building 100, this will be the “northeast” side. For Building 200, this will be the “west” side. If field observations determine that these locations are unsuitable, the locations may be changed following review and approval by BOR of the proposed locations.

17. Is flexible ductwork acceptable in the attic space, or is metal ductwork required throughout?

Response: Flexible ductwork is acceptable.

18. Are ground-mounted packaged HVAC units acceptable, or does BOR require separate outdoor units and indoor air handlers?

Response: Ground-mounted packaged HVAC units are acceptable if the replacement units meet the capacity and airflow distribution of the existing systems.

19. Is there a designated location or approved method for terminating condensate drains?

Response: SOW has been updated to include installation of a condensate discharge line and drain. AIf possible, Reclamation would like the condensate lines to terminate into a basic underground drain system instead of the water falling directly onto the ground surface near the building. There are wild burros on the property that have caused damage to water infrastructure in the past, and they will likely damage the condensate line if it is left exposed.
