Sol Amendment #1 Miami HVAC Repair/Replacement

Continued... Continuation page from block 14. The purpose of this amendment is to respond to the questions received for Solicitation No. 1333MF26Q0109. Combined Synopsis Solicitation: 1333MF26Q0109 Response to Questions: Q1 - Could you please confirm whether bid, performance, and payment bonds are required for this solicitation? A1 - The winning vendor must be licensed and bonded in the state the work is to be performed. The attached wage determination is for services not construction as we are considering this work to be repairs and maintenance not construction. Q2 - Could you please clarify whether we may use a subcontractor that is licensed and bonded in the State of Florida to satisfy this requirement, or whether the licensing and bonding requirements must be held by the prime contractor?¿ A2 - The government has no privity with a subcontractor therefore all requirements fall upon the primary contractor. Subcontractors must also be licensed and trained to work in the state. Q3 - The SOW states that vendor teams shall be licensed and bonded to work in Miami, Florida. May the prime contractor satisfy this requirement through its licensed and bonded HVAC subcontractor, or must the prime contractor independently hold the applicable HVAC license and bond? A3 - Please see responses above Q4 - For Evaluation Factors 2 – Experience and 3 – Past Performance, will NOAA consider the relevant experience, qualifications, and past-performance references of the prime contractor’s proposed HVAC subcontractor and key personnel? A4 - Both the prime and any proposed subcontractors should have the relevant past performance and experience working on this type of requirement. Q5 - For Tasks 4 and 5, should offerors price the quotation assuming complete replacement of both systems, or should anticipated repair and full-system replacement be priced separately? A5 - Complete replacement of both systems Q6 - For Task 8, should offerors assume replacement of all identified strainer/check valves for purposes of the firm-fixed-price quotation? If so, can NOAA provide the applicable valve sizes, types, and quantities? A6 - The government does not have documentation of the valve sizes, types, or quantities for these assemblies, and no as-built or submittal data is available. The scope of Task 8 is limited to inspection at the three locations identified and replacement of only those assemblies found leaking or non-operational. For pricing purposes, offerors shall assume one strainer/check valve assembly at each of the three locations, serving fan-coil equipment. Offerors should state any pricing assumptions in their quotation. Any condition materially different from the above will be addressed by the Contracting Officer. Q7 - Please confirm that offerors should provide one firm-fixed price for CLIN 0001 covering the complete 60-day requirement. The combined synopsis references monthly and annual pricing for base and option years, while the SOW appears to establish a single 60-day project requirement. A7 - There is only one CLIN in this action. Verbiage in the invoicing section is standard template language. Q8 - Is Miami-Dade County Notice of Acceptance or equivalent Florida Product Approval required for all replacement HVAC equipment under Tasks 1–5, or only for the Task 3 warehouse system? A8 - Miami-Dade County Notice of Acceptance or equivalent Florida product approval is required for all exterior-mounted replacement equipment, including the Task 1 and Task 2 packaged rooftop units and the outdoor condensing units under Tasks 3, 4, and 5. Indoor air handlers are not subject to this requirement. Q9 - Please confirm whether permits from the local municipality are required for the replacement of the HVAC equipment. A9 - The Miami campus is a federally owned facility. County mechanical permits are not required for work performed on this site. All work shall comply with the applicable standards listed in the SOW, including the National Electrical Code, ASHRAE standards, and Miami-Dade County product approval for exterior-mounted equipment. Q10 - Is a bid bond required with the proposal, or are performance and payment bonds required only from the successful contractor after award? A10 - Please see responses above Q11 - For the 4-ton and 2-ton mini-split units identified for diagnosis, repair, or replacement, based on the current condition of the equipment, we believe replacement is the most appropriate option. Please confirm whether we may submit pricing based on complete replacement of these units. A11 - See A5. Offerors shall price complete replacement of both the Task 4 and Task 5 systems, including the outdoor condensing unit and the matching indoor unit. Permitting Q12 - Does this project require a Miami-Dade County mechanical permit for each unit, or does NOAA handle permitting internally for work on this campus? A12 - See A9. A Miami-Dade County mechanical permit is not required for this work. Q13 - If a county permit is needed, who submits the application, the contractor or NOAA? A13 - Not applicable. See A9. Q14 - Is the Miami-Dade product approval (NOA) documentation required before we submit our quote, or only later at the time of permit application? A14 - Product approval documentation is not required with the quote. Offerors should identify the proposed make and model in their technical approach. Documentation of Miami-Dade Notice of Acceptance or equivalent Florida product approval shall be provided to the technical point of contact prior to installation. Q15 - Is a stamped engineer drawing required for the rooftop package unit replacements, or are manufacturer spec sheets sufficient since it is a same-capacity swap? A15 - Manufacturer specification and cut sheets are sufficient. Signed and sealed engineering drawings are not required for like-for-like capacity replacement. Q16 - Who schedules and conducts inspections once the work is complete, a county inspector or someone from NOAA? A16 - Because no county permit is required for this work, there will be no county inspection. Government acceptance will be performed by the Contracting Officer or authorized representative per CAR 1352.246-70. The contractor shall contact the technical point of contact to walk the punch list and close out the project per Deliverable 5 of the SOW. Roof Condition Q17 - The roof stands for the rooftop units appear structurally sound, with the equipment itself showing the corrosion. If we are replacing the units, can the existing roof stands be kept as-is without resealing or replacement, or is that required regardless? A17 - The SOW requirement stands. Tasks 1 and 2 require the existing roof stand be repaired or replaced as required to properly support the new unit. The contractor shall assess each stand and repair or replace as needed. Existing stands may be reused only where structurally sound and free of significant section loss. New ductwork must be installed and sealed to the roof in all cases. Site Access Q18 - Do our technicians need a badge or facility ID to access the campus for each visit? A18 - A PIV or CAC is not required. Contractor personnel will be granted visitor access. The contractor shall provide a list of personnel names to the technical point of contact in advance of each visit. Personnel must present government-issued photo identification on arrival. Q19 - Is there a laydown area near the roof that could be reserved for our crane when installing the RTUs on the Annex? A19 - Yes. A staging and crane setup area near the Annex can be made available. The specific location and duration will be coordinated with the technical point of contact after award. The contractor is responsible for protecting pavement and for maintaining clear fire lanes and emergency vehicle access at all times. Q20 - Is there power to the rooftop units, or would that require separate coordination? A20 - All five units identified in Tasks 1 through 5 are existing installed equipment, and existing electrical conditions were available for inspection during the September 9 site visit. The contractor shall reuse or modify existing circuits as required to serve the new equipment. Any electrical work necessary to connect and support the replacement equipment is the contractor's responsibility and shall be included in the firm-fixed price. The SOW requires the contractor to supply all labor, materials, equipment and supplies required to complete the listed tasks, and the government will furnish no resources toward completion of this requirement. Q21 - What are the allowed working hours on site, standard business hours only, or is night or weekend work permitted for the noisier tasks such as the rooftop units? A21 - Normal working hours are 7:00 am to 4:00 pm ET, Monday through Friday, excluding federal holidays. Work outside those hours may be permitted with advance written requests submitted through the Government POC. Approval depends on government escort availability after hours and is not guaranteed. Past Performance Q22 - Can our past performance references include general contracting projects of similar scale and complexity, not limited to HVAC-specific work, given our broader project management and delivery record? A22 - See A4. At least three past performance references are required. References should demonstrate experience installing and maintaining commercial HVAC systems comparable to those described in the SOW. General contracting references may be submitted in addition but will be evaluated on their relevance to this requirement. Coral Lab Coordination Q23 - Who should we contact directly to schedule the cooling outage for the Coral Lab, given that it supports live specimens? A23) this information is not relevant to the proposal. The government POC’s will be distributed at time of award Strainer/Check Valves (Task 8) Q24 - To confirm, is the scope for this task to inspect the strainer/check valves in rooms 319, 208, and the mechanical room, and only replace the ones found leaking or non-operational? A24 - Confirmed. Task 8 requires inspection at all three locations, with replacement of only those assemblies found leaking or non-operational. See A6 for pricing. Q25 - Regarding Task 8, the strainer/check valves in rooms 319, 208, and the mechanical room. Are there existing isolation valves on either side of the strainer/check valves that would allow us to shut off water flow locally for replacement, or would the lines need to be frozen to isolate the work area? A25 - Shutoff valves are available to isolate each of the three rooms. The government does not have documentation of whether local isolation exists immediately upstream and downstream of each strainer/check valve assembly. Line freezing is not anticipated. The contractor is responsible for the means of isolation and for draining and refilling any affected piping. Any planned outage shall be coordinated with the technical point of contact in advance. POST-SITE-VISIT CLARIFICATION QUESTIONS GENERAL / PROJECT-WIDE QUESTIONS Q26. Manufacturer / Brand Requirements Are replacement HVAC units required to be Rheem, or are equivalent manufacturers such as Carrier, Trane, Daikin, Goodman, or other approved manufacturers acceptable? A26 - The government is relying on proposals to recommend the best solution to meet the requirements Q27.
