25. Sheet MH-301 calls to remove the existing Veeder Root Fuel Tank monitoring panel and replace it with TM-1, a new Preferred brand Fuel Sentry leak detection panel. The existing Veeder Root inventory probes and leak sensors will not work with Preferred brand panel. Can a new Veeder

Root panel be provided instead?

Veeder Root and other brand fuel monitors can be submitted for review and acceptance by the AE and COR for equivalency of the scheduled basis of design brand equipment, subject to meeting all requirements on the contract documents.

Existing level sensor and leak detection sensors shall be demolished and replaced with new sensors, per drawing MH-302, plan notes 1, 2, 9, 11, & 12.

26. Does TM-1 monitor fuel/water levels for the day tank or the main fuel storage tank?

Panel 30-TM-1 shall monitor fuel & water levels for the main fuel storage tank. Fuel & water levels for the day tank 30-DT-1 shall be monitored by the day tank onboard controller, and connected to the DDC system via the day tank DDC interface.

It would also be acceptable for panel 30-TM-1 to monitor fuel & water levels for both the main fuel storage tank (E)30-DFT-1 and day tank 30-DT-1. Note that this approach would not negate the requirement to provide a DDC interface for 30-DT-1 and integrate that into the DDC system.

27. Specification for fuel containment pipe in section 23 10 00 paragraph 2.2 D calls for schedule 10 gauge black steel piping. Piping Schedule on sheet MJ-601, note 2, calls for 10 Gauge

Galvanized steel piping. Please clarify if containment piping shall be black or galvanized.

For exterior double-containment piping systems, outer containment piping shall be 10-gauge black steel with 2-coat fusion epoxy exterior finish per specification 23 10 00-2.2-D. This shall be provided as part of a factory-engineered system, prefabricated for field installation.

28. The existing Veeder Root inventory probes and leak sensors located inside the fuel storage tank and between the double walls of the tank will not work with Preferred brand TM Please advise if new inventory probes and leak sensors are required. Please advise if new control wiring between the sensors and TM-1 is required.

Existing level sensor and leak detection sensors shall be demolished and replaced with new sensors, per drawing MH-302, plan notes 1, 2, 9, 11, & 12.

29. sensors within the double wall pipe have been problematic due to access and drying out after getting wet. Due to the short amount of pipe near the main storage tank at Bldg 30, can non-discriminating sensors in J-wells be used in lieu of cable sensors?

Cable-type discriminating sensors shall be provided as specified in 23 10 00 Para. 2.3.C.6.

30. Sheet MH-301 calls to remove the existing Veeder Root Fuel Tank monitoring panel and replace it with TM-1, a new Preferred brand Fuel Sentry leak detection panel. The existing Veeder Root inventory probes and leak sensors will not work with Preferred brand panel. Can a new Veeder

Root panel be provided instead? Veeder Root systems have local authorized service contractors and local parts distributors.

Refer to RFI-025 response

31. Building 30: Drawing MJ-601 Fuel Systems Schedule. The fuel monitor manufacturer is

Preferred. Existing fuel monitor is Veeder Root. Will Veeder Root 450 be acceptable as a substitute? The installation will be easier if you replace the existing Veeder Root with the upgraded Veeder Root 450.

32. In general, can aboveground double wall piping be deleted? For ASTs it isn’t required to be double wall piping. A lot of times you would want to see if anything is visibly leaking if its aboveground so you can fix it. With double wall containment piping you wouldn’t be able to see it if its contained in double wall piping.

Double wall piping is required for exterior locations (i.e., at the Bldg 30 exterior main fuel tank) as indicated on the piping schedule on sheet MJ-001 and can not be deleted.

33. If double wall piping cannot be deleted, MJ-601 and MH-302. SOCCO 15.0 and 23 10 00 2.2

Pre-engineered double containment piping. This means aboveground fuel lines will need to be ordered and manufactured in the main land as pre-fabricated piping. The cost of getting drawings and measurements correct in the mainland is minimal and can be very expensive. Can primary black steel pipe and threaded fittings be used as primary pipe and installed inside of FRP double wall piping and fittings. With this it can adapt to underground FRP primary adapters and FRP pipe double wall piping stubbing out of the ground? Welding with existing underground fuel piping and existing tank can be fire hazard with fuel lines not being completely emptied and cleaned. Short run will also save time and material if we go with threaded fittings without have a welder onsite.

Factory engineered & prefabricated double-containment systems with black steel primary and containment piping are required as specified in specification 23 10 00-2.2.

34. Will day tank emergency vents need to be run outside of the building?

All day tank and belly tank vent (including emergency vent) piping shall be routed to the exterior per Spec 26 32 13 Para. 2A.5.B.4; Para. 2B.5.B.4; NFPA 30; NFPA 37. Note that existing tank vent piping in Building 30 and Building 32A is intended to be re-used for this purpose.

35. BUILDING T-1 WING: For bidding purposes how much fuel will we need to pump out and dispose of?

450 gal of diesel max.

36. BUILDING 32A : Drawing MJ-601 Fuel System Schedule. Remote fill station. Does this need be stainless steel?

Standard painted steel construction is acceptable for the Building 32A fuel fill station 32A-FP-1.

Product shall be the specified Simplex unit, or shall meet or exceed the construction of the specified/scheduled unit.

37. Regarding Bldg 30, see questions below from Caterpillar:

a. What is the basis of design for the retrofit Square D I-line panel noted as B1 on sheet 000-EJ-

002? This states the 50A FP beaker is included while the one-line shows the new 100AF/50AT FP breaker outside the panel gen mounted.

Basis of design is to use gen switchboard as a junction box to connect the two sections of conduit from the generator to the existing conduits serving the ATS. Detail 1 on 000-EJ-002 should show the existing 50A breaker as being demolished to allow for space for a new 100A breaker to be installed.

b. Is the intent to replace the bus and all the breakers while adding an addition 1200A breaker dedicated and KK to the main for the load bank apparatus noted as B6 on sheet 000-EJ-002?

The intent for B30 is to replace the switchboard bus and all breakers while adding the new 1200A breaker for the load bank (KN B6 on 000-EJ-002). The new 1200A load bank breaker is to be provided as a separate/adjacent apparatus (not within the existing switchboard interior) per

Drawing 030-EP-012 KN 19. Contractor shall confirm space availability and submit shop drawing for the complete switchboard retrofit arrangement. Reference: Dwgs 000-EJ-002, 030-

EP-012.

c. Does B30 require an alternate power source per NEC 700.3 (f)? We see this fulfilled with the use of a Triple Switch on B32 and T-1 but not on B30.

The design in Bldg 30 does comply with NEC 700.3(f). A dedicated 1200A circuit breaker with a keyed interlock connected to a connection cabinet operates simular to the Triple Switch.

38. Is Veeder Root and Simplex an approved manufacturer to the specified Preferred equipment on sheet MJ-601?

39. Corridor C1-05, please advise if this area can be closed for the installation of the new 2-hr rated shaft partition.

46. Will the Government consider including an Economic Price Adjustment (EPA) clause to address significant fluctuations in material pricing?

No.

47. If tariffs are imposed on materials (e.g., steel, wood) after bid submission but before award, will the Government allow a price escalation even if the materials remain Buy American–compliant?

This may be considered on a case by case basis.

48. Will the Government provide detailed requirements for contractor badging? Please clarify the PIV process, including documentation, background checks, and estimated processing time.

This project will not require submissions for PIV badges. Base access for personnel will be submitted thru the Army's Sponsorship Portal website at least two months in advance of start of

Construction. The VA has no control over processing time for base access as this is a US Army

Garrison installation.

49. How soon after contract award does the Government anticipate issuing the official Notice to

Proceed?

The Notice to Proceed is anticipated to be issued after the kick off meeting, which will occur within 2 weeks of award.

50. Will the Government consider reducing the required bid validity period (e.g., to 60 days) to account for inflation and contractor pricing risk?

No, 30 days is the minimum.

51. Can the Government confirm the stated contract duration is accurate, considering phased access and execution requirements?

If lead times affect the Contractor’s ability complete the project within the period of performance than the period of performance can be reviewed and changed once project is awarded and lead times are verified.

52. Safety specification has multiple locations that reference both the OSHA standard and the EM

385-1 standard, sometimes in the same sentence. The solicitation documents do not clarify a standard, please provide clarification on the standard that will be utilized for this project?

The most stringent requirement will apply.

53. May one individual serve in dual or multiple roles (SSHO, QCM, Superintendent) if fully qualified? If not, may the Superintendent also serve as SSHO?

No individual will serve in multiple roles.

54. Specs call for professional photographer to provide construction documentation including weekly site progressions, including –

10. Weekly (21 Max) Site Progressions - Photographic documentation capturing the project at different stages of construction. These progressions shall capture underground utilities, excavation, grading, backfill, landscaping and road construction throughout the duration of the project.

11. Regular (8 max) interior progressions of all walls of the entire project to begin at time of substantial framed or as directed by the COR through to completion.

12. Detailed Exact Built of all Slabs for all project slab pours just prior to placing concrete or as directed by the COR.

13. Detailed Interior exact built overlapping photos of the entire building to include documentation of all mechanical, electrical and plumbing systems in every wall and ceiling, to be conducted after rough-ins are complete, just prior to insulation and or drywall, or as directed by COR.

14. Finished detailed Interior exact built overlapping photos of all walls, ceilings, and floors to be scheduled by COR prior to occupancy.

Based on the specifications, a full-time professional photographer will be required to be onsite daily to capture all the photographs required. This is a significant added cost to the project. Please confirm the VA expects and requires a full-time professional photographer onsite daily for documentation?

If a full-time professional photographer is not a requirement, please clarify the requirements/expectations to fulfil the photo documentation obligations?

A full-time professional photographer is not required. However, official documentation photos shall be taken with a DSLR camera and not a cell phone camera. Cell phone camera pictures tend to be grainy and unusable when zoomed in.

55. The specification identifies several possible Special Inspections with a specialty engineer

(PE) performing inspections for areas of the SOW that could be required by the VA. This requires third parties to be hired to perform this work. Please provide a list of ANY special inspections required as part of this project including but not exhaustive of steel, concrete, geotech, seismic, and fire?

The VA will not provide temp generators. The Contractor is responsible to have a backup generator installed, tested, and function prior to taking down a buildings generator system.

The contractor will be responsible for maintaining generator backup power until the permanent building generator system is installed, tested, and turned over to the VA.

66. Will the VA provide temporary cooling/heating during system cutovers? If not, should the contractor include them?

The VA will not provide temp cooling/heating. Contractor will need to plan and provide temporary backup systems to any system that is affected. Any outage that affects patient care will need to be scheduled outside of Clinical hours Monday - Saturday 0700-1630.

67. Are existing electrical and low voltage conduit pathways intended to be reused?

Yes, where shown on drawings, existing conduit pathways are intended for reuse. Contractor shall field-verify condition and fill capacity of existing conduit prior to pulling new conductors.

68. Advise if 1.0 power factor is acceptable for both these tests or if 0.8 power factor is required for either.

Testing at 1.0 power factor (unity) for both factory testing (Spec section 26 32 13 - 1.4) and field testing (Spec section 26 32 13 - 3.2F) is acceptable. Testing at 0.8pf is not required.

69. 3.1 Installation: will factory recommended IBC seismic certified integral isolators be accepted in lieu of any spring type isolators?

IBC seismic-certified integral isolators are acceptable as an alternate to spring-type isolators upon review and approval of submittal prior to installation from COR. Reference: Spec 26 32

13 Para. 3.1.C; Spec 13 05 41.

70. Does B30 require an alternate power source per NEC 700.3 (f)?

We see this fulfilled with the use of a Triple Switch on B32 and T-1 but not on B30.

Refer to RFI 37c

71. Drawings CS-001 states- “Do not place subbase on soft, unstable, or rutted subgrade. If subbase material becomes mixed with unsuitable material, remove, dispose of, and preplace the subbase material at no additional cost to the client.” Unsuitable material is an existing and unforeseen condition therefore impossible to price.

Will this statement be stricken?

Will the VA allow an unforeseen conditions cost added to the price sheet to meet this requirement? Please clarify.

The CS-001 subgrade note is a quality control requirement, not a waiver of differing site conditions (DSC) claims. If genuinely unforeseeable unsuitable subgrade is discovered during excavation, stop work, document with photographs, and submit a DSC change order request to the COR per FAR 52.236-2. The CS-001 note does not eliminate DSC rights for conditions not reasonably discoverable during site investigation. The VA will review requests on a case-by-case basis.

72. Please confirm, a third-party state certified land surveyor must certify engineering as builts related to civil work?

Yes confirmed.

73. Will confined space work be required as a component of this project?

The utility corridor at E-Wing and MH-7C are considered confined spaces.

74. What is the basis of design for the retrofit Square D I-line panel noted as B1 on sheet 000-EJ-

002?

RESPONSE: Basis of design for B30 Square D I-Line panel retrofit inside distribution section of the existing generator switchboard. Submit shop drawings showing complete B30 panel retrofit for COR review. Reference: Dwgs 000-EJ-002, 030-EP-012.

75. This states the 50A FP beaker is included while the one-line shows the new 100AF/50AT FP breaker outside the panel gen mounted. We see this fulfilled with the use of a Triple Switch on B32 and T-1 but not on B30.

76. Does B30 require an alternate power source per NEC 700.3 (f)?

77. Please clarify, for B30, the genset control retrofit is a modification to the existing control panel section in the gen room or a new control and distribution section be required, a completely new apparatus?

For Building 30, the existing switchboard enclosure is to remain. A new genset control retrofit is in scope per Dwg 000-EJ-002; Spec 26 32 13.

78. Please confirm the location of the fuel supply pump for the day tank? Is this remote, to be installed at the main tank or in proximity of the day tank? (30-DFT-1). I don’t see that on sheet on MJ-701

A duplex pump package (including pumps 30-FP-1 & 30-FP-2) is to be installed near the existing main fuel tank 30-DFT-1 and will supply fuel to the day tank 30-DT-1. Refer to drawing(s) MH-302 and MJ-701.

79. Please provide pictures of the inside electrical room BA105 as well as pictures of the existing switchboard, automatic transfer switch, generator Disc and panel BEL1.as we were not provided access during the site visit.

81. Sheet 000-EJ-001 Detail 4 shows the new path for the DDC fiber optic route. Also, on sheet

032-EP-0B1 shows this route thru existing THH-1A and TMH-7C (Note 5) but does not indicate the conduit pathway is existing from the parking structure to RM2D16. Please confirm if this conduit pathway is existing. If this pathway is not existing, please confirm the conduit size.

The path from B30 to the parking garage will utilize existing network of underground conduits and vaults.

82. Multiple sheets refer to drawing EJ-001 Detail 4 for fiber type and length, this information is not in this location. Please provide the details for all fiber type and lengths.

Drawing reference 0EW-EP-001 is obsolete. Drawing reference should read 0T1-EP-011.

83. Our submittals goes to the COR for review and approval, Is the COR no longer reviewing and approving submittals on this project?

The COR will oversee all submittals, some will need review by the A/E prior.

84. On Sheet 000-EJ-004 Building T-1 Partial Electrical One-Line Diagram per Phase 2 Keynotes

85. Who is providing the Gear, Lighting, Generator, Fire Alarm Package(s) for this Project? If we are, are there National Account Vendors we must go through, or can we go through our own

Vendors.

All equipment packages for this project — including electrical distribution gear

(switchboards, panelboards, ATS), lighting, generators, and fire alarm — are

CONTRACTOR-FURNISHED, CONTRACTOR-INSTALLED (CFCI) unless explicitly noted otherwise in the contract documents.

The VA does not mandate the use of national account vendors for this project. The contractor may procure equipment from their own approved vendors provided the equipment meets all specification requirements and submittal approvals.

The contractor may select any manufacturer whose equipment meets Spec 26 32 13 requirements. Generator manufacturer submittals must be approved by the COR/A/E prior to procurement.

The fire alarm system must be compatible with and integratable into the existing VA facility fire alarm system. Confirm existing FA panel manufacturer with the COR prior to selecting equipment.

86. The CQC manager position customarily requires a graduate engineer, graduate architect, or a graduate of construction management, OR a minimum of 5 years construction experience on construction. The change in language to with 5 years construction experience will create an extremely limited pool of available qualified candidates. This may require a third full time staff member on a limited jobsite, daily. This will add considerable cost to the project.

Please confirm that the VA is requiring the CQC manager possess one of three degrees AND

5 years field experience instead of the customary formal training OR required field experience?

This is a requirement. Deviation not allowed.

87. In SAM.gov there are 2 solicitations for what looks like the same scope project. See below screenshots. I think one is based off of the pre-solicitation and the other was created as a solicitation. Just want to know if both solicitations' documents should be incorporated with our RFP Response?

The documents are the same for the solicitation based off the pre-solicitation and solicitation.

The documents attached to the solicitation should be incorporated with RFP response.

88. Is the bid due date 5/17/26 as per SF 1442 form? This is a Sunday which isn’t a common due date and we wanted to confirm this date is correct.

Due date for this solicitation has been extended to Friday 5/22/2026 12PM HST.
