o At the doorway that separates the RedBird Simulator room and the facility corridor.

o At the lobby in the SouthEast corner of the facility, separating off that exterior entrance so it can only be used by government users accessing the Command Suite.

10. Is any landscaping restoration required for this project? For example; topsoil, seeding, and fertilizer.

• Landscaping restoration with sod is required for any areas that are disturbed by the Contractors’ actions.

11. Does the government have a preferred Direct Digital Control for HVAC company? If so, please provide the contact information

• The existing HVAC controls and BAS is Johnson Controls, this is standardized for all buildings on Columbus AFB. The Government does not have a standardized company for any other HVAC/Controls systems.

12. Existing Lighting Fixtures- Please provide any available documentation, maintenance records, testing reports, or assessments identifying the cause of the non-functioning lighting fixtures and other related electrical systems for this facility. Confirm whether fixture repair, ballast replacement, fixture replacement, or additional electrical upgrades are anticipated to be included within the project scope.

• All interior lighting fixtures in sections of the facility that are within scope will be replaced with new LED equivalent fixtures under this project. Also, new fixture whips, light switches, and occupancy sensors will be installed under this project.

13. Structural Analysis and Design Responsibility- Please clarify the extent of structural investigation and analysis expected from the Design Team. Additionally, provide any available existing structural drawings, calculations, reports, or facility assessments that may assist in evaluating structural impacts associated with demolition, new wall construction, door installations, and other modifications identified in the Statement of Work.

• All existing As-Built drawings for this facility have been compiled and have been sent to Contracting Squadron.

• The Contractor shall determine if any modifications to walls, doors, or other components will have an effect to any structural and load-bearing aspects of the facility. If any modifications do affect the structure, the Contractor shall include designs from a structural engineer for these elements.

14. Please provide any available as-built drawings, renovation records, utility surveys, or existing condition reports that identify abandoned systems, concealed utilities, or undocumented modifications. Additionally, clarify how unforeseen conditions encountered during construction will be addressed contractually.

• All existing As-Built drawings for this facility have been compiled and have been sent to Contracting Squadron.

15. Hazardous Materials Survey- Based on the apparent age of the facility and the anticipated demolition activities, the potential exists for hazardous materials to be present within building components that may be disturbed during construction.

Please confirm whether all hazardous materials requiring abatement have been identified in the report and whether abatement will be performed by the

Government or is to be included in the contractor's scope.

• The asbestos reports provided are assumed to be accurate and all inclusive.

According to the multiple reports, confirmed asbestos is still present in the 9"x9" floor tiles and black mastic (1–10% Chrysotile) under office/classroom carpets, the roof flashing and penetration mastics (15–30% asbestos), and potentially within remaining heating hot water pipe fitting insulation (3–10% Amosite). High concentrations of lead paint remain on the south Mechanical Room double doors and various interior metal fixtures, including door frames and fire extinguisher cabinets (up to 8% lead content). The contractor is required to abate all hazardous materials within the scope of construction activities in accordance with their own contractor-developed abatement plan, which must be authored and executed in strict compliance with all applicable federal, state, and local environmental codes and regulations.

16. Please identify any Government-furnished furniture, lockers, appliances, or equipment and clarify which existing furnishings are to remain, be relocated, or be removed.

• The Government will not furnish any equipment for this project for Contractor install.

• The facility users will relocate smaller items into several rooms of the facility that are not within the scope of this project. Large items and equipment like cubicles, desks, tables, cabinets, etc. will be left in place and it will be the responsibility of the Contractor to cover and protect these items during construction activities.

Users will also remove and store anything from the walls that they want to keep. The Contractor must carefully remove and set aside the decorative ceiling tiles located in the existing classrooms

17. Please confirm that the existing HVAC systems have sufficient capacity to serve the renovated spaces and additional room configurations. If deficiencies are discovered during design, should capacity upgrades be included within the designbuild scope?

• The government expects that the capacity of AHU1 and AHU2 will be sufficient to handle the room reconfigurations since some rooms are being removed to be fed by dedicated HVAC systems.

18. Please identify the existing HVAC controls manufacturer and BAS platform and clarify whether controls modifications shall integrate with the existing EMCS system.

• The existing HVAC controls and BAS is Johnson Controls, this is standardized for all buildings on Columbus AFB. Any new controls shall integrate with the existing EMCS System. Currently, the system at building 230 is on the JCI N2 configuration.

19. Is Testing, Adjusting, and Balancing (TAB) required for all air systems or only those modified by construction? Is formal commissioning required?

• A complete TAB is required for all new HVAC and exhaust systems as well as the complete AHU1 and AHU2 HVAC systems. Any other separate HVAC system does not require TAB.

20. Please confirm that existing domestic water and sanitary systems are adequate to support the new shower, lockers, and restroom modifications without major infrastructure upgrades.

• The existing domestic water and sanitary sewer systems at the each bathroom is expected to be adequate to be modified without major system upgrades.

21. Please confirm existing panel capacities and available spare breakers. If insufficient capacity exists, are panel replacements considered part of the designbuild scope?

• It is anticipated that there will be enough of an increase in electrical load that a new panelboard will be required at the south end of the facility to serve the added loads from the new HVAC system and clothes dryer loads. The main distribution panel in the North Mechanical Room has a spare 225A breaker titled “STANDBY CHILLER” that can be used to feed this new panel.

22. Please clarify whether lighting controls must comply with UFC and current energy code requirements and whether occupancy sensors are required in renovated spaces.

• Lighting control systems must comply with all applicable UFC and energy code requirements. Occupancy sensors are required in renovated spaces.

23. Please confirm whether fire alarm devices impacted by renovation are limited to relocation of existing devices or whether additional devices and programming are required.

• Additional devices and programming are required under this project where there are not enough existing devices to cover the room reconfiguration.

24. Please confirm that the existing sprinkler system has sufficient capacity for room reconfiguration and identify whether hydraulic calculations and modifications are required.

• Building 230 does not have a fire sprinkler system. Room reconfigurations will not require the installation of a new fire sprinkler system.

25. Please identify the responsible party for communications cabling and terminations and clarify whether SIPR and NIPR connections will be provided by the

Government or the contractor.

• The installation, splicing, and termination of communications cabling (for both NIPR and SIPR) will be executed by Government personnel. The Contractor is responsible for installing the communications infrastructure and pathways including conduit, junction boxes, pull boxes, cable trays, buss bars, and pull strings.

26. Please identify any Government-furnished network equipment and indicate the contractor's responsibility for racks, patch panels, fiber, and terminations.

• The Government will not furnish any network equipment for this project. The Government is responsible for installing all cabling, patch panels, and terminations.
