12. The PCR Indicates several concept floor plans. Please clarify that the proposed floor plan for this project is the one that utilizes half of the hangar and the connected restrooms shown on page 105 of the PCR_SOW document.

The proposed floor plan is the one on page 147, and also the separate pdf labeled UMT floor plan.

13. Are there any as-builts available for this building?

Available as-builts attached.

14. Please provide utility as-builts to this building.

Available as-builts attached.

15. Please confirm the ceiling height required for the Hangar Bay area to receive the new trainer units.

Assume bay height must remain over height of Mega doors for trainer units.

16. Please confirm if 10'-0" ceilings are acceptable for the Tool Room, Telecom Room, and admin areas.

10’ ceilings is acceptable in those areas.

17. On the site visit, it was observed that there are (2) existing fire pumps in this building. Please confirm that the scope of work for this project involves the installation of an additional fire pump as stated on page 151 of the PCR_SOW.

Yes.

18. Please confirm that contractors are to create a fire wall between the UMT Training Bay and the rest of the hangar.

The contractors are to create a fire wall between the UMT training Bay and the rest of the hangar.

19. Please confirm that building upgrades are limited only to the area of work as shown in the concept drawing on page 105 of the PCR_SOW document.

That is not accurate. The floor plan the government is selecting is on page 147 and on the separate floor plan document. The SOW contains all areas of work which includes other areas besides what is on the floor plan.

20. During the site visit, it was mentioned that all of the exisitng Mega-doors will remain in place; page 13 of the PCR_SOW states that there is (1) Mega-door to be removed and the wall infilled for this project. Please confirm that none of the hangar bay doors are to be removed for this project.

The PCR is correct, 1 Mega door is to be removed and infilled.

21. Please confirm that contractors are to leave the existing trench drain in place, and that no work is to be performed on the trench drain.

The structural requirements of the PCR covers the infilling requirements of the trench drain.

22. Section 2.3.6 and 2.3.9 in the "B995 Conversion SOW" scope of work state that contractors are to provide HVAC systems to each simulator. How many simulators are intended to be installed for this project?

It will be 1 HVAC system for admin and 1 HVAC system for the hangar bays, not individual systems per simulator.

23. Please provide an assumed HVAC load or provide requirements for heatiing and cooling for each simulator.

Assume 4 devices producing 41,000 BTU/h each, assume 18 people working in area. The area shall be maintained between 50-85°F and between 20-80% humidity. Assumptions for bidding purposes only.

24. Please provide an assumed electrical load for each simulator unit.

Assumptions for bidding purposes only, 120/208V at 100 Amps for 4 devices. Provide power to design build contractor installed disconnect, future contractor installing equipment will take from installed disconnect to UPS/device as future work.

25. Please provide assumed dimensions (LxWxH) for each simulator unit.

10’x10’x10’. Assume no lower than Mega Door height for clearance.

26. Will the building be occupied during construction? If so, will phasing be required?

The facility will not be occupied during construction.

27. If phasing is required, please provide phasing requirements.

No phasing requirements.

28. Please confirm that no planes, equipment, or furniture will be required to be move by the contractor prior to the start of construction.

The design build contractor will not be responsible for moving planes, equipment, or furniture prior to the start of construction.

29. If equipment is required to be relocated by the contractor, please confirm the types and quantity of equipment or furniture to be relocated.

None required.

30. Please confirm if a single, duly qualified individual may "triple hat" and serve as the project superintendent, QC Manager, and SSHO.

The superintendent and QC manager shall be separate individuals for this project. SSHO may be dual hatted with the QC manager, but no triple hat.

31. Please confirm if contractors are to assume that no hazardous materials are present in the area of construction.

The PCR "Hazardous Materials Remediation" section identifies several specific items within Building 995, including approximately 618 fluorescent light bulbs, 331 presumed PCB containing ballasts, 10 smoke alarms, and one suspect mercury-containing thermostat.

32. If contractors are to assume that hazardous materials are present within the construction area, please provide a quantity that contractors can assume requires abatement.

The contractor is to abate the hazardous materials listed in the PCR.

33. Could the government provide a single SOW document that combines all appropriate requirements of the "PCR_SOW" and the "B995 Conversion SOW" in order for contractors to have a single, clear scope to provide pricing for?

B995 Conversion SOW is the SOW for the project. The PCR is a supplemental document supporting the requirements in the B995 Conversion SOW.

34. Government Furnished Equipment (GFE) vs. Contractor Furnished (UPS Systems) See 38

35. The PCR states under "Interior Electrical" that "Combination Uninterruptible Power Supplies (UPS) and Power Distribution Units (PDU) must be furnished and installed by the Contracting Officer vendor (TBD)".

See 38

36. The PCR also notes under "User Equipment" that an Uninterruptible Power Supply (UPS) is required for the facility.

See 38

37. Conversely, the SOW explicitly states in Section 2.4 that "The Government will not furnish any equipment or materials for this project".

See 38

38. Please clarify if the Design-Builder is responsible for furnishing and installing the UPS/PDU systems, or if these will be provided by the Government/Contracting Officer vendor as stated in the PCR.

The UPS for these simulators will be Government furnished/Government (separate contractor) installed after project completion.

39. Administrative Area Demolition Scope Contradiction See 43

40. The PCR "Space Planning Diagrams" section states, "The existing B995 administrative building is not being renovated or demolished as part of this project".

See 43

41. However, the PCR "Fire Safety Deficiencies" section states, "The admin area of the building is not currently protected by a sprinkler system".

See 43

42. That same section immediately follows with, "This area will be placed on the demolition list and therefore, no sprinkler system will need to be added".

See 43

43. Please clarify if the existing administrative area is to be demolished under this contract, or if it is remaining in place and outside the scope of work.

The existing administrative area is remaining in place.

44. Fire Suppression Demolition Limits See 48

45. The SOW Section 2.3.15 instructs the contractor to perform fire protection work as outlined in the PCR.

See 48

46. The PCR "Fire Suppression" section states that the "existing AFFF wet pipe sprinkler system currently protects the hangar".

See 48

47. The PCR further states, "This system must be demolished for the entire hangar and replaced with a new wet pipe sprinkler system".

See 48

48. Please confirm if the Design-Builder is responsible for demolishing the AFFF system throughout the entire physical hangar, even if portions of the hangar fall outside the specific "in-scope construction area" designated for architectural and HVAC renovations.

The Design Builder is responsible for demolishing the AFFF system throughout the entire physical hangar, even portions of the hangar that fall outside the specific “in-scope construction area” designated for architectural and HVAC renovations. The new wet pipe system the Design-Builder is responsible for shall cover the whole hangar.

49. Classroom Square Footage / Tabular Discrepancy See 52

50. Table 3B in the PCR ("Facility Program") lists the Academic Instruction Spaces as requiring two (2) Classrooms.

See 52

51. The table lists the square footage for these classrooms as "1,080", but the adjacent column lists the total as "1,320".

See 52

52. Please clarify the required square footage for the classrooms, as two 1,080 SF classrooms would total 2,160 SF, not 1,320 SF.

The DAFMAN column has the minimum required SF for the classrooms, the PCR has each as 1,320 SF each classroom for a total of 2,640 SF. The intent is for each classroom to be 1,320 SF so it is over the DAFMAN minimum.

53. Simulator/Trainer Quantities and Utility Sizing See 57

54. The PCR "Space Planning Diagrams" section specifies that the high-bay space is provided "for ease of configuration of the four (4) trainers that are planned for the facility".

See 57

55. The SOW Section 2.2 also mentions housing "four (4) maintenance simulators".

See 57

56. However, the PCR Table 3B ("Facility Program") and Section 3.3 ("User Equipment") only account for one (1) Seat/Canopy Trainer and one (1) Avionics/Cockpit Trainer.

See 57

57. Please clarify the exact number and types of simulators the facility and its utilities must be designed to support so accurate electrical and HVAC loads can be calculated.

Please refer to RFIs 23 and 24.

58. Hazardous Material Abatement Responsibilities See 61

59. The PCR "Hazardous Materials Remediation" section identifies several specific items within Building 995, including approximately 618 fluorescent light bulbs, 331 presumed PCB containing ballasts, 10 smoke alarms, and one suspect mercury-containing thermostat.

See 61

60. The SOW addresses the disposal of lead-based paint chips at the Government's cost in Section 6.11.2.

See 61

61. Please clarify if the Design-Builder is responsible for the abatement, removal, and disposal costs of the specific fluorescent bulbs, PCB ballasts, mercury thermostats, and smoke alarms listed in the PCR.

The design builder is responsible for the abatement, removal, and disposal of the specified items.

62. Telecommunications Pathway vs. Inside Plant Cabling See 66

63. The PCR Section 3.3 ("User Equipment") states that "Inside plant cabling, connectors, patch panels, terminations, testing and labeling" are required.

See 66

64. The remarks for that section note that "All pathways conduits, boxes, basket tray, handhole, etc. must be in place for GFGI inside plant cabling".

See 66

65. The SOW Section 2.3.30 states that "Conductors, terminations, and testing of the NIPRnet system shall be performed by Base Communications".

See 66

66. Please confirm that the Design-Builder's scope for interior communications is strictly limited to providing the empty pathways (conduit, boxes, basket tray, racks, backboards) and that all physical copper/fiber cabling, terminations, and testing for the networks will be Government Furnished / Government Installed (GFGI).

That is correct.

67. HVAC System Quantities See 70

68. Section 2.3.9 of the SOW states that the contractor must "Design, furnish, and install three (2) separate HVAC systems".

See 70

69. The text contradictorily specifies both the written word "three" and the numeric value "(2)".

See 70

70. Please clarify the exact number of independent HVAC systems required for this scope.

2 systems, 1 for admin/classroom area and 1for training bay area.

71. Life Cycle Cost Analysis (LCCA) Requirements See 74

72. Section 2.3.11, paragraph 2, states that sustainable principles, including a life cycle cost analysis, will be integrated into the HVAC system's design and construction in accordance with UFC 1-200-02.

See 74

73. However, the SOW does not explicitly list an LCCA report in the design submittal stages outlined in Section 3.6.

See 74

74. Please clarify if a formal LCCA report must be submitted for Government review to satisfy this requirement.

No formal LCCA report required.

75. If a formal LCCA report is required, please specify at which design phase (e.g., 35% or 65%) this submittal is expected.

No formal LCCA report required.

76. Energy Modeling & ASHRAE 90.1 Compliance See 81

77. Sections 2.3.4 and 2.3.5 mandate that the new interior insulation must be designed to meet ASHRAE 90.1 requirements.

See 81

78. Additionally, Section 3.2.3 requires a psychrometric/load design analysis to be submitted at the 35% design phase.

See 81

79. Please clarify if a comprehensive, whole-building energy model is required to prove overall ASHRAE 90.1 and UFC 1-200-02 compliance.

A comprehensive whole building energy model is not required.

80. Alternatively, please confirm if standard heating/cooling load calculations and prescriptive insulation compliance are sufficient to meet the design intent.

Standard heating/cooling load calculations and prescriptive insulation compliance are sufficient to meet the design intent.

81. Existing High-Bay Lighting Replacement Scope See 85

82. Section 2.3.22 dictates that existing bay lighting will remain in place unless illumination requirements fail to meet UFC 3-530-01.

See 85

83. The SOW states that compliance will be determined by a photometric analysis provided at the 35% Design phase.

See 85

84. Because the necessity to replace the lighting will not be established until after the contract is awarded and the 35% design is evaluated, please clarify how this should be bid.

See 85

85. Should bidders carry a specific financial allowance for new high-bay lighting, or will lighting replacement be addressed via a contract modification if the existing fixtures fail the analysis?

The bidders should bid on new high-bay lighting with LEDs and new ballast.

86. Do the Superintendent, SSHO and QC Manager need to be 3 separate individuals?

The superintendent and QC Manager shall be 2 separate individuals. The SSHO can be the superintended or QC manager.

Replace with spray foam insulation to help meet HVAC requirements and to prevent loose insulation from falling on new ceilings. The new ceilings for admin/bay areas may also have insulation added to meet requirements.

116. During the site visit, we observed two existing fire pumps that appear to provide redundant fire pump capacity to the facility, reportedly rated at approximately 2,500 gpm. The PCR indicates that a new fire pump will be needed for the proposed wet-pipe sprinkler system. Please confirm whether a new fire pump is required, or if the existing fire pumps may be reused if they are determined to have adequate capacity and condition.

New fire pump required.

117. Additionally, the existing fire alarm control panel appeared to have limited capacity and may not be adequate to support additional initiating and notification devices required for the renovation. The PCR indicates the existing Notifier panel is to be reused/relocated and modified. Please confirm whether the existing FACP is to be reused, or whether it should be removed and replaced with a new fire alarm control panel capable of supporting the renovated facility.

New FACP is required do not reuse existing.
