Design/Build ANG ACS Weapons Facility

1. A concept plan is referenced but has not been provided. Will the government provide one? Yes the concept floor plan, provided by NGB as a best practice floor plan layout, is from a northern tier Connecticut area base and will need to be site adapted to support structural and mechanical design appropriate for this locality.

2. The government has denoted the potential for ‘multiple building site locations’ with varying infrastructure requirements associated with each. Is it the governments intent that the D‐B team prepare separate designs for each location at the 35% submission? No, follow process discussed in ANGETL 10‐3 para 3.2.1.2.1 regarding site selection which is a “Type A‐1” (15% Investigative Design) process having two site options as opposed to three – one primary and one alternate site. You will recommend the site and get authorization to proceed to Type A‐2 (35% Concept Design) based on the site approved under Type A‐1 process. One concept emerges at 35% design submission. Advocacy is up to contractor, the ANG does not have a site preference. Contractor will not have to provide two full 35% concept designs.

3. We understand that the first submittal is at 35% however it looks like there are no items that will require government approval, including finish selections, which is very unusual. If this is the case, could the government please provide ‘preferred selections’ so that a color board can be started in the initial design phase. Follow ANGETL 15‐01‐00 Section 4.7 “Interior Design” for finishes, particularly Table 4.1.

Colors selections of said finishes can be submitted for local user preferences through the material submittal process during construction.

4. What do the required acoustic treatment ratings in the room data indicate? For example, they are listed as noise sensitive, minimum, medium, high, etc. Will an end user define treatment requirements for the varied spaces? See DoD Manual DODM 5200.01, Volume 3, Feb 24 2012, Change 3, Effective July 28, 2020 at the link here:

https://www.esd.whs.mil/Portals/54/Documents/DD/issuances/dodm/520001m_vol 3.pdf?ver=MJfVD‐nRd2HTyLSzDse9VQ%3d%3d

5. B2030 Exterior doors references a provided hardware schedule. Can you provide this? See section B2030, Paragraph 8. Also, the designer of record develops these requirements as a specification.

6. Which doors require locks and keycard readers/IDS? Exterior mandoor access into the facility, and, coverage of the secured van storage bay (accessed by the two sets of roll up doors) will require access control/IDS coverage. Honeywell Vindicator Access Control/Intrusion Detection (ACS/IDS) systems only, no substitutions. Entire installation operates all ACS/IDS on Honeywell vindicator systems only.

7. Furniture is not in scope, but a layout has been requested. Input on preferred layout, spatial use, and occupancy will be needed. Occupancy will be for 18 personnel with work stations. Layout and spatial use will be determined by design agent in cooperation with the end users.

8. There is a discrepancy in the RFP one section indicates that the interior walls must be painted gypsum, and another indicates the walls will be ½” plywood. Please confirm which is required. See DoD Manual DODM 5200.01, Volume 3, Feb 24 2012, incorporating Change 3, Effective July 28, 2020 mentioned also in item 4 above.

9. On page 22 Section 40 of the SOW, the following statement is included. “Prior to the start of design, the Designer of Record shall meet with the Government’s Fire Protection Engineer to determine the extent and types of fire protection required” The assumption is that the Design FPE will be onsite for the initial site visit and meet with Government’s FP Engineer at that time. Correct, exchange information but the governments contact will be a fire chief or assistant fire chief not an engineer. The fire protection design is contractor responsibility per “UFC 3‐600‐01 Fire Protection Engineering for Facilities”, Change 6, dated 06 May 2021.

https://wbdg.org/FFC/DOD/UFC/ufc_3_600_01_2016_c6.pdf Contractors Design FPE will follow the UFC and stamp/seal shop drawings and hydraulic calcs and submit to 165 CES Base Civil Engineer for acknowledgement/acceptance prior to release for construction start.

10. Is the location in an area subject to freezing where a dry pipe system would be required as stated in D4040? No.

11. Can the water supply information be provided referenced in section D4020 of the SOW? Water supply from City of Savannah owned water mains is adequate for domestic uses. Design per UFC’s.

12. Is this facility storing any weapons or required to meet any requirements for munitions storage? No

13. The requested transformer is a high‐K rated transformer sized @ 45kVA, this seems small considering HVAC will be quite robust for this area, please clarify the intent, is this just for the weapon systems equipment? In addition to the systems required by code to provide Electrical Power and HVAC to the facility spaces, there are two pieces of mobile equipment that will be parked within the van bay (access from roll up doors) and require dedicated additional Electrical and HVAC provisions:

a. Van Bay Mobile Equipment #1 – Requirements:

i. Electrical: 208/230 VAC, 3‐phase 50/60Hz, 100 A min not to exceed 110 kVA;

ii. HVAC Cooling: 60,000 British Thermal Units per hour (BTU/hr);

iii. HVAC Heating: 50,000 BTU/hr

iv. Supply and return points of connection at the equipment is 16” round duct

b. Van Bay Mobile Equipment #2 – Requirements:

i. Electrical: 208/230 VAC, 3‐phase 50/60Hz (5‐wire), 100 A minimum;

ii. HVAC Cooling: 62,000 British Thermal Units per hour (BTU/hr);

iii. HVAC Heating: 51,150 BTU/hr

iv. Supply and return points of connection at the equipment is 16” round duct

v. Air Flow: 3,500 cfm

Notes to mechanical engineer:

A single commercial HVAC unit can provide dedicated support to both pieces of mobile equipment provided that dual‐thermostats and zone damper control is utilized along with either hot gas bypass or Rawal valve device incorporated.

The dedicated equipment HVAC unit(s) sit outside facility on concrete pad(s). Anticipate 16” flex duct connections between the mobile equipment and the facility exterior wall. Rigid exterior duct work from facility wall to HVAC equipment.

14. The building looks to require appx. a 600‐800 amp service but we need to have an equipment list and usage loads to clarify. Also, does the end users equipment operate on 480 or 120/208? Both mobile equipment units operate 208/230VAC, 3‐ phase, 50/60 Hz, 100 Amp minimum each.

15. Is there any kind of DC working system required? and static grounding requirements? No DC requirements. Copper ground bus needs to be in one small location where there will be workstations in the mobile equipment van bay. During concept design users will identify. Won’t be whole building or wrapping room interiors with copper bussing. Both pieces of mobile equipment in the van bay need a place for grounds to clamp on for static discharge. Follow UFC 3‐575‐01 Chapter 2.

16. Is there a delineation where the contractor stops and base security takes over for the IDS/ACS? Typically, SFS handles IDS and the contractor provides pathways.

If not, is Honeywell/Vindicator available to provide a preliminary design for this?

Provide Optional price to furnish and install Honeywell vindicator system who provides design as part of their price. Base contract is raceways/pathways, rough in for future equipment. Contact “Brandon.Davis3@Honeywell.com”

17. We will need the available fault current/configuration of the transformer available to power this structure. Georgia Power can provide this information.

Contacts:

Primary: Zu Mendez Casillas – 912‐531‐5935, zmendezc@southernco.com;

Alternate: Jimmy Brown – 912‐239‐7298, jibrown@southernco.com;

18. Is Georgia Power responsible for the medium voltage transformer? Or is the base responsible? If the GC should carry this cost is there an authorized Allowance value?

Georgia Power will provide the contractor a primary electrical service up to and including the Georgia Power owned pad mounted transformer at no cost to the contractor since this is a new facility and thereby “revenue generating”. Contractor is responsible for furnishing all electrical services between the Georgia Power owned transformer and the facility. Georgia Power will make terminations inside its transformer. There will be no overhead services, all work is underground. Contractor owns all coordination responsibilities with Georgia Power as though Georgia Power were their own subcontractor.

19. G4010.1 indicates MV connection, is this the contractor or utility company’s responsibility? In context of G4010.1, the only responsibility of Georgia Power is furnishing and installing its own transformer and primary service to that transformer.

The base telecommunications network is government owned underground copper/fiber plant in manholes/duct‐banks. Contractor will “design‐build” both interior plant and outside cable plant providing facility connectivity to the nearest government owned telecommunications manhole, in accordance with latest published version of UFC 3‐580‐01, sub‐referenced within the UFC 1‐200‐01.

20. What is the desired size of the transfer switch (amp rating) for full building load? Design‐Build. Contractors retained design engineer will determine. Follow UFC 1‐200‐01 and all sub‐referenced UFC’s therein. Manual Transfer Switch only, no auto transfer.

21. D5090.2 indicates a 60kW generator, should it be sized to accommodate this generator? Yes, but the government also owns 30kW mobile generators. Either will work work based on electrical engineers preferences. Those are the only two options.

Government will furnish the contractor the plug receptacle to mount at transfer switch. Contractor will wire and test. Government will provide the mobile generator for contractor to test.

22. What percentage of the building load will the generator be required to back up? The entire facility.

23. There is no dedicated space called out for the TR/EF. Given the small size of the building, what is the government’s intent? The minimum per UFC is 10 x 8. We will determine appropriate location in the concept design stage with government telecom POCs. Due to secure area requirements it will likely be an interior wall mounted telecomm enclosure in the main operations center.

24. Can the government provide a desired room/equipment layout for the TR/EF?

No, that’s a design element for the contractor.

25. Will the switching equipment be Government or Contractor furnished?

Telecomm switches will be government furnished equipment.

26. What are the currently available base CATV and Comm connections at the manholes? Fiber? Coax? Who will tie‐in to the local CATV Comm Manhole? Gov’t or GC? Do you want the GC to supply a conduit only to the existing manhole? See attachment for existing comm outside plant infrastructure. Contractor will run ductbank(s) to nearest manhole. Contractor will tie‐in. Contractor will provide plant and terminations.

27. Are there any specific requirements for the Lightning Protection System the design team should be aware of besides NFPA 780 and applicable AFI/AFMANs? Yes, start at UFC 3‐575‐01“Lightning and Static Electricity Protection Systems” Chapter 3.

28. Does the Government want a UL Master Label Certificate for the Lightning Protection System? ‘counterpoised’? See D5010 and UFC 3‐575‐01, para 3‐1.2.

Regarding counterpoise, unless specifically required by the UFC for this application based on soil resistance to ground, the answer to counterpoise is no.

29. In the technical specifications, there are requirements for wall receptacles for workstations, these will be fed from below the floor, what is required for the walls?

General UFC guidance? Additional quads seem excessive. See concept design.

30. Appendix C, Table C1 does not exist for workstation load data, please provide requirements if required above providing each workstation with a dedicated quad.

Was this intended for the Weapons Systems equip? See concept design.

31. Is the intention for the corner‐mounted exterior lights to be on continuous (photocell) or motion activated? Photocell

32. Legrande underfloor Walkerduct system requires 100% ‘end’ user’ input for a design of their products. Can the government rep get this ‘end user input’ from the base Data Communications group? Yes, during design and prior to acceptance of 35% design submission to the ANG for review.

33. Is the ‘raised flooring’ required only at the office space? Yes

34. Is there need for a cable tray under the raised flooring besides the Walkerduct system? To be determined by design agent

35. Will the end user want an anti‐static carpet purchased with the Legrande Walkerduct system for full warrantable issues? No

36. The Davis Bacon Wage Sheets issued are not for Chatham County…will a new D‐ B Wage sheet be issued? The correct wage rate sheet has been uploaded to sam.gov

37. Will the government be satisfied with a fully galvanized PEMB structure for best weather corrosive resistance? Contractors design architect and/or structural engineer will follow the proposal technical requirements. No customizations.

38. Will there be any fencing containment requirements around this facility? If the alternative site location is selected, can the fence contained area be considered a non secured site. No permanent fencing requirements around facility. The alternate worksite in the all grass area allows for a “freezone” non‐secured site by direct connecting the jobsite to the installation perimeter, and creating a dedicated penetration through installation perimeter to allow contractor direct uninhibited access to the jobsite, without having to work pass & ID and access through installation security forces. Yes, that method of direct dedicated access will be approved due to its adjacency to the installation perimeter fence. Free‐zones will always require allowing security forces access to inspect the site. Your site fence would need to meet full installation perimeter fenceline requirements of UFC 4‐022‐03 “Security Fences and Gates”.

Updates and Clarifications to the project requirements as follows:

RFP Document: All References to “ASCE 7‐10” or “ASCE 7”are rescinded and replaced with “ASCE 7‐16” to align with the IBC 2018 references within the latest UFC 1‐200‐01 DoD Building Code. Do not reference or apply “ASCE 7‐05” or “ASCE 7‐10” to the design of the project. This includes B10 Superstructure, B3010 Roof Coverings, B3030 Wind Uplift.

NGB Preferred Basis of Design: In the mechanical plan sheets, all references to “ECU” are for expeditionary military government furnished HVAC units that typically support tents. This was done as a cost cutting measure to get under their budget. This is not what we are doing here, all HVAC unit(s) are commercial “contractor furnished contractor installed”.
