29. Does Attachment 4 assume a single electrical crew or stacked crews during shutdown, tie-in, and testing phases?

Attachment 4 is the Itemized Cost Breakdown and is a standardized form for recent construction projects in this region. Offerors should refer to the project requirements in the RFP, SOW, Specs, and Drawings to confirm their price accurately reflects the work involved.

30. Are there any restrictions on apprentice ratios or manpower composition during sensitive electrical work or testing periods?

Yes, apprentice restriction to a 1:1 ratio, meaning one apprentice for every one journeyman or master electrician, to ensure proper supervision, particularly for specialized or hazardous tasks.

31. Is electrical manpower sequencing assumed to align directly with AHU shutdown and replacement phasing, or are additional work windows anticipated?

Electrical manpower sequencing assumed to align directly with AHU shutdown and replacement phasing. It is also the contractor’s Means, Methods and responsibility to ensure the project is properly staffed for project execution.

32. Please confirm whether unforeseen infection control measures impacting electrical work are considered contractor responsibility or subject to contract modification. – Please refer to RFO 52.236-2 and RFO 52.236-3, which are incorporated into the RFP.

33. Please clarify how partial completion of electrical work will be validated relative to testing, commissioning, and acceptance requirements.

Electrical testing under this project is limited to equipment directly supporting the replaced AHUs, ERUs, and associated temporary HVAC systems. Partial testing may occur at the direction of the Commissioning Agent (CxA) to support commissioning of the affected HVAC systems. However, equipment acceptance and completion is dependent on final acceptance by the VA.

34. Please confirm whether there is flexibility to rebalance labor categories within the electrical scope should actual field conditions differ from initial assumptions.

Please see the response to RFI- 28. Contractor’s labor mix needs to be able to properly execute the work with applicable qualifications, certifications, and safety training.

35. Spec states HVAC must be tied into FA system, but FA drawings do not show points or devices. Please provide updated FA drawings or point schedule.

Per the Contract Documents, HVAC equipment shall be tied into the Fire Alarm System (FAS). The electrical drawings identify the relevant scope and coordination requirements for these tie‑ins, including the affected AHUs/ERUs and associated power/control interfaces shown on Sheets E‑401, E‑402, E‑403, E‑404, E‑405, and E‑501. Final device locations, point mapping, and sequences will be confirmed through the FA contractor’s shop drawings and the commissioning plan in accordance with Division 28 and Specification Section 01 91 00 – Commissioning.

Updated FA drawings are not required at this time; the FA shop drawings and point list developed by the VA‑designated FA service provider shall govern, limited to devices directly impacted by the AHU/ERU replacement work and associated ductwork modifications.

36. The contract documents include a Lead-Based Paint Removal spec section (02 83 33.13) and drawings HA101/HA102 outlining lead abatement on the 1st floor and penthouse. Please clarify the scope of hazardous material abatement in this project:

Are the highlighted areas on HA101/HA102 the only locations requiring lead paint removal, presumably where equipment or ducts will be disturbed? For instance, HA101 shows a first-floor plan – is that the location of FCU-1/2 or piping where paint will be scraped? We will follow OSHA lead-safe practices regardless but want to confirm if we should include a certified abatement contractor for full removal in those areas or just stabilization.

The only positive LBP results were the white paint on AHUs in rooms 1A147 and 6A104. The rest of the tests were negative:

37. Has an asbestos survey been conducted? None is referenced explicitly, but if any asbestos-containing materials (ACM) (e.g. old pipe insulation or transite panels in mechanical rooms) are present around our work, it would impact our approach.

Please advise if asbestos remediation is required or if the site is clear of ACM in the work zones.

Yes, a total of 33 new samples representing 70 total material samples were taken, none of which was identified to contain asbestos.

38. Demo drawings indicate removal of abandoned ductwork and refrigerant lines, but spec does not confirm scope boundary. Please confirm the exact demo boundary especially for inaccessible ceiling areas.

a. Basement Mechanical room BA101: Scope of demolition is limited to basement mechanical room BA101. Contractor to notify COR of any deficiencies in ductwork exterior to this room, specifically outside air ductwork routed between the exterior louver and the mechanical room.

b. First Floor Mechanical room 1A147: Scope of demolition is limited to first floor mechanical room 1A147.

c. Fourth Floor Mechanical room 4A105: Scope of demolition is limited to fourth floor mechanical room 4A105. Note,

d. Sixth Floor Mechanical room penthouse A6004: Scope of demolition is limited to sixth floor penthouse mechanical room A6004.

39. Specs call for ceiling finish patch-back, but no elevation or material detail shown.

Please provide finish schedule for all affected ceilings.

There is no ceiling in these mechanical spaces, and any patch would be to the structural deck above – no finish schedule for the ceilings are necessary.

40. Can you confirm existing type of FA annunciator panel?

Siemens Desigo CC Management

41. Is new FA annunciator panel required? If so, where?

Fire Alarm System (FAS) devices included in the scope of work includes the testing, relocation, or re‑certification to those devices directly impacted by the AHU and ERU replacement work. These include but are not limited to smoke detectors, supervised relay’s, cabling, and required programing changes within the existing fire alarm system. New panel is not anticipated due to the reuse / replacement of existing detection devices, however, contractor is responsible for ensuring a complete and working system at the completion of the project.

42. For temp units 03A and 03B, the duct is shown penetrating the exterior louver, but there is no direction on how that is to tie-in to the existing ductwork. Is the duct main on the other side of the wall? Are we to run ductwork all the way to the mechanical room?

There is existing outside air ductwork routed from the mechanical room to the louver.

Temporary ductwork will connect to the existing ductwork. See as-built below:

43. Is the contractor able to route ductwork in a manner different than the drawing routing?

Any deviation from the drawings must be generated by the contractor then submitted to be reviewed and approved by the A/E and VA COR.

44. Can temporary ductwork be run using high static flexible ductwork or is it to be routed in metal duct? Please provide a specification for the temporary duct, unless this is at the contractor’s discretion.

No. Rigid ductwork shall be utilized. Any deviation must be reviewed and approved by the A/E and VA COR. Please refer to duct spec for all ductwork: 23 31 00 HVAC DUCTS

45. JCI is listed as the controls system integrator for this project. However, depending on location within the hospital we have seen Hoffman or Trane as the designated integrator. Can you please confirm JCI is to be the designated integrator for this project?

JCI is to be the designated integrator for this project.

46. Is the controls system integrator to be a separate contractor from the controls system installer?

a. Installer and integrator can be separate contractors.

i. Single Source Responsibility of subcontractor: Either the DDC Contractor or the System Integrator shall obtain hardware and software supplied under this Section and delegate the responsibility to a single source controls installation subcontractor. The Integration subcontractor shall be responsible for the complete design, installation, integration, and commissioning of the system. The controls subcontractor shall be in the business of design, installation and service of such building automation control systems similar in size and complexity.

47. Can some units be placed in parallel if they serve different areas, or must we strictly do one phase at a time?

Follow phasing as indicated on drawings, 4 phases, one phase at a time.

48. The RFP notes that existing electrical infrastructure will be utilized for new equipment. We need confirmation that the existing feeders, circuits, and breakers are sufficient for the new AHUs, condensing units, pumps, etc. For example, if a new fan motor has higher horsepower or if a new ACCU requires a larger circuit, will panelboard upgrades or new feeds be required? The electrical demo and new power plans show reuse of circuits, but it’s not explicit if breaker sizes change. Please verify the new equipment electrical loads against existing circuit capacities and indicate any required electrical modifications (wire size, breaker trip, disconnects) beyond simply reconnecting to existing power.

a. The existing electrical infrastructure is intended to be utilized for the new HVAC equipment in accordance with the Contract Documents. Where replacement equipment requires connection to existing electrical systems, new circuit breakers shall be installed to match existing characteristics and type, as required.

b. The electrical drawings identify the required breaker and conductor sizes for the new and replacement HVAC equipment, including any modifications necessary beyond simple reconnection. Refer to the project electrical drawings for equipment loads, breaker sizing, conductor sizing, and disconnect requirements.

49. The plans include a Temporary AHU Power Plan and a temporary panel schedule, implying that power must be provided to the temporary AHUs and exhaust fans during phasing. Please clarify the source and capacity for this temporary power: Are there spare circuits in the existing electrical system to feed the temporary units, or is the intent to use a portable generator or temporary distribution panel? If using existing power, confirm that the added load of temporary DX AHUs and fans (e.g. two 12,000 CFM exhaust fans) won’t trip existing systems or require load shedding. Also, specify if any automatic transfer or backup power is required for these temporary units to protect critical areas in event of normal power loss.

a. Temporary power for the AHUs and exhaust fans shall be provided as shown on the Temporary AHU Power Plan and the temporary panel schedule. The design drawings show the proposed temporary equipment to be used and the existing demand for the temporary equipment; contractors shall utilize the circuits and capacities identified on those drawings. INSTALL NEW CIRCUIT

BREAKERS TO MATCH EXISTING CHARACTERISTICS AND TYPE. DRAWINGS

SHOW BREAKER AND CONDUCTOR SIZE.

b. Source and capacity: Where existing panels/circuits are indicated on the temporary power plan and schedule, those shall be used; no additional temporary distribution panels or portable generators are required unless specifically shown or directed by the Contracting Officer. Loadings shall not exceed the ratings indicated on the drawings and schedules.

c. System impact: The added loads for the temporary DX AHUs and exhaust fans are accounted for in the temporary power plan/schedule. Contractors shall connect and configure per the drawings so as not to exceed indicated capacities and shall coordinate any required outages with VA.

d. Automatic transfer / backup power: No automatic transfer or backup power is required for the temporary units unless specifically indicated on the drawings or in the specifications. Testing/commissioning requirements remain as defined in Specification 01 91 00 – Commissioning and applicable Division 26 provisions.

e. All work shall be performed and documented in accordance with the Contract Documents. Any proposed deviations (e.g., use of portable generation or alternate distribution) shall be submitted for A/E and VA COR review and approval prior to implementation.

50. The RFP and specs indicate that new AHUs will connect to existing chilled water and steam/condensate lines within the mechanical rooms. We seek clarification on the tie-in points and any new appurtenances needed. For chilled water and steam: are there existing isolation valves at each mechanical room entry that we can shut to do our connections? If not, should we install new valves or plan system-wide shutdowns? For condensate drainage from AHU cooling coils or steam humidifiers:

the spec notes we must collect and remove condensate from units, but drawings don’t clearly show where to pipe it. Should we run condensate to the nearest floor drain or hub drain, and are new condensate pumps needed if gravity flow isn’t possible? Please confirm the intended design for these piping connections (valve locations, drain points, etc.), as they are not explicitly detailed.

a. Plan to demo mains back to local main and cap. Provide new valves and appurtenances to new piping. Scoped is limited to the mechanical rooms, but full shutdowns will be necessary to install new valves. Schedule shutdowns with COR as required.

b. Run new condensate piping to nearest floor drain / floor sink / hub drain.

Drains are located adjacent to the existing units.

51. The scope includes “structural modifications” as needed for the new equipment.

We noted Structural drawing S-SK1 provides a sketch for temporary AHU duct support, but we need clarification on permanent support requirements. For example, do the new AHUs, condensing units (ACCU-1 to 4), or pumps require new housekeeping pads, inertia bases, or steel dunnage? If a new rooftop or penthouse unit is heavier than the old, has the structural capacity been verified or should the contractor carry an engineered solution to reinforce beams/slabs? The documents don’t explicitly show any new beams or pad details for the equipment replacements. Please advise if we are expected to design/build any new supports or if existing building structure is confirmed to be adequate for all new loads.

Equipment pads will need to be expanded to accommodate new AHUs. The existing structure has been verified against new equipment loads. No building structural work is anticipated in regards to new permanent air handling units (including exhaust fans).

52. Will the VA’s infection control staff perform routine inspections and air sampling, or does the contractor need to hire an independent ICRA monitor to document compliance? We want to ensure we implement the correct infection control and interim life safety measures at all stages (especially since this is an active hospital).

Contractor to meet all requirements of ICRA Level III as part of all work on the contract. This includes all work areas to ensure veteran safety.

VA engineers or COR will inspect the job site daily. VA’s infection control staff will perform routine inspections weekly since the nature of the work is being done in the mechanical room, penthouse room, roof, and outside patio and not next to inpatient areas.

53. The specifications call for comprehensive Testing, Adjusting, and Balancing (TAB) of HVAC systems. We need to confirm the extent of this work. The project replaces major air-handling equipment but does not otherwise alter terminal devices in the occupied spaces. Are we required to re-balance all air outlets and hydronic terminals throughout the areas served by the new AHUs, or just balance the new equipment to match the design flow rates? For instance, if AHU-2 serves an entire floor, should the TAB agent revisit every room on that floor to verify airflows and adjust VAV boxes, reheat coils, etc.? The spec suggests all systems be balanced in all modes, but we want to clarify if that includes portions of the system not physically modified.

The existing equipment being replaced is to be tested for baseline values. Only new equipment is to be balanced to the design flow rates.

54. We note that normal VA working hours are 7:00 AM to 4:30 PM, Monday through Friday. Please confirm if any work must be performed outside of those hours.

Specifically: will high-noise operations (core drilling, demolition of concrete or ductwork) or system shutdowns (like switching over an AHU or tying into electrical/steam mains) be restricted to evenings or weekends to avoid disrupting hospital operations? Likewise, if any areas served by an AHU cannot be without HVAC during the day, we may need to do the cutover at night when those areas can tolerate an outage (despite temporary units, there may be moments of transition).

Understanding any off-hours or phasing constraints imposed by the medical center (such as “no power shutdowns during clinic hours” or “work in ICU only after 10 PM”) will help us plan labor shifts and communicate with subcontractors.

For any work that impacts on hospital normal operation, contractors will have to coordinate in advance with the project COR/PM for off-hours or weekend work.

55. Please provide contact information for the control systems integrator, as the GC is responsible for getting an integration quote from them.

The control systems integrator is listed below.

Marc Skeen | Hoffman Building Technologies Inc.

Unknown.

59. Will the VA extend the bid due date by two weeks after all RFI responses are provided, allowing time to review RFI answers and provide the best price possible?

If practicable with procurement lead times, the VA will attempt to allow this.

60. Will the VA clarify if there is any asbestos in the areas proposed to be under construction?

The only positive LBP results were the white paint on AHUs in rooms 1A147 and 6A104.

Testing was performed on September 25, 2024.

62. Will the VA provide the most recent asbestos abatement survey for the affected areas?

Please see the report from September 25, 2024 for the area of work.

63. The specifications call for a dedicated Superintendent, SSHO, and Quality Control Manager. Having all three dedicated to this project for the full period of performance will generate an excessive cost given the scope of work. Will the VA amend the requirements to allow any one person to fill multiple roles?

Yes, this person must be competent and possess a high level of experience to satisfy VA requirements.

64. Will the VA allow the Prime Contractor to delegate an OSHA 30 superintendent and associated responsibilities to a member of the subcontractor's team?

No.

65. Will the Prime Contractor and its subcontractors have access to any on-site restroom facilities?

Yes, and they must be reinstalled immediately after the units are transferred into the mechanical room. However, if there is any damage, the contractors will be responsible for the repair or providing new ones.

82. Sheet Note 4 found on MD103 and MD104 of Attachment 8 – Drawings, states:

Contractor to do full test and balance survey of entire service space from air handling unit to all terminal units and final registers prior to demolition […]. Based on this note, will the VA provide full set of mechanical drawings for the hospital or equipment counts for the areas served by these units? A total count is required to provide the best price possible.

Perform TAB at the AHU. The existing equipment being replaced is to be tested for baseline values. Only new equipment is to be balanced to the design flow rates.

83. Will the entire service space from air handling unit to all terminal units need to be re-tested and balanced (re-TAB) after the air handling units are replaced?

No, AHUs and exhaust fans being replaced will be balanced to match design.

Terminal units and space air devices are outside of the scope of this project.

84. While the temporary units are installed, does the contractor need to do any pressure / air change verification testing for the entire service space from air handing unit to all terminal units?

Contractor to verify the air flow and pressure at the point of connection between the temporary ductwork and existing ductwork. The service space is outside of the scoped of this project.

85. During construction, noise and vibrations will occur within the mechanical rooms.

Are there any adjacent spaces that will require quiet hours or special noise/vibration restrictions during normal working hours? If so, what are the quiet hours for those spaces?

Surrounding the construction job site are non-patient care areas, mostly offices, but excessive noise will impact office meetings and team collaboration, such as core drilling etc. So, the GC needs to coordinate with the COR in advance for after-hours or weekend work. Otherwise, work must be done during normal working hours.

86. Please confirm manufacturer controls mounted at the factory are acceptable.

If the provided controls meet the requirements of the DIV 23 specifications and can perform the sequences as stated on the construction drawings we take no issue.

However, pre-package and pre-programed controls that do not meet the requirements of the specifications, or can perform the required sequence of operation are not acceptable.

87. The existing air handing units have Trane controls. Please confirm the option of the new AHUs to be tied into existing Trane system at the facility for a competitive bid is acceptable.

New controls are to be BACnet and integrated into the head end Climatech control system. Please see General Notes on controls drawings.

88. Has it been verified that there is adequate electrical available in the building now to run the temporary units? They will be DX units (meaning it will require more power than an AHU.)

a. The design drawings and temporary panel schedules indicate that adequate electrical capacity is available to operate the temporary DX units, which have higher electrical demand than the permanent AHUs.

b. The Contractor shall review the panel schedules for the temporary panels to verify that the actual temporary DX units provided are at or below the electrical demand noted on the design drawings. Temporary equipment shall be selected, installed, and operated in accordance with the breaker sizes, conductor sizes, and panel capacities shown in the Contract Documents.

c. If the electrical demand of the proposed temporary DX equipment exceeds the demand shown on the design drawings, the Contractor shall notify the Architect/Engineer (A/E) and the VA Contracting Officer’s Representative (COR) for review and direction prior to installation. No installation of equipment exceeding the design demand shall proceed without written approval.

89. Is there enough power to run more than one temporary unit at a time, in each of the dedicated areas of temporary units?

Yes. The electrical load calculations at the time of design indicate there is sufficient capacity to operate more than one temporary unit at a time within each dedicated temporary equipment area as shown in the design drawings.

90. How many hours of shut down time will the contractor have to make the final connections the temporary unit for the existing duct and turn it on as temporary?

This will have to be done after hours or on weekends to avoid disruption. VA expects it to be done within 8 hours.

91. Materials will be stored offsite in a secure warehouse with Insurance. Please confirm we can bill on and be paid for stored materials.

It cannot be guaranteed, but the VA may accommodate payment for stored materials only if the conditions under RFO 52.232-5(b)(2) and VAAR 852.232-70(d) are met. If approved by the CO, 10% retainage would likely be held IAW 52.232-5(e) until work related to those materials is completed.

92. What if any, will be the retainage amount on this project?

The CO may hold 10% retainage IAW 52.232-5(e) if necessary.

93. SOW page 3 states that the contractor needs to reinsulate all the duct and piping at the AHUs. Please confirm if the contractor will be reinsulating only disturbed, reworked, new work and tie in areas. Please clarify the extent of the re- insulation. Is it everything in the rooms, even pipe and duct that is not touched?

The contractor is required to document any existing deficiencies. The scope of work includes reinsulating all reworked items and replacing insulation on all main ductwork within the mechanical room associated with the AHU replacement.

94. Is there a service elevator that contractors will be able to use?

Yes.

95. The work schedule in the specs is 7:00- 4:30 M-F. Will contractors be able to work additional hours to make ties ins or set equipment if it makes sense to the owner?
