The following have been added by full text:

RFI'S AMENDMENT 0007

Spec Ref Drawing Ref Question Response 07 42 63 A-710 1. Insulated Fabricated Wall Panel Steel Sheet Gauge:

The Exterior Finish Schedule on Sheet A-710 of the drawings indicates that the basis of design for insulated metal panel, MP-1, is the 7.2 Insul-Rib profile manufactured by Metl-Span and the basis of design for MP-2, is the striated profile manufactured by Metl- Span.

Subpart 2.1.1 Steel Sheet within Subpart 2.1 Panel Materials of Specification Section 07 42 63 Insulated Fabricated Wall Panels states that the steel sheet for the insulated fabricated wall panels is required to be fy = 20 gauge.

Subpart 2.4.1 Steel Sheet within Subpart 2.4 Panel Materials of Specification Section 13 34 19 Metal Building Systems states that the steel sheet for the panel materials is required to be fy = 18 gauge.

However, according to the product data sheet from Metl Span, the CF 7.2 Insul-Rib Insulated Metal Wall Panel has exterior face options of 26, 24, or 22 gauge and interior face options of 26, 24, or 22 gauge.

Additionally, according to the product data sheet from Metl Span, the CF Striated Insulated Metal Wall Panel has exterior face options of 24 or 22 gauge and interior face options of 26, 24, or 22 gauge.

Please clarify which gauge(s) for both the exterior and interior faces of the basis of design insulated metal panels the Contractor is to include in its bid.

See revised Sections 07 42 63 and 13 34 19 as part of enclosed amendment for revised panel gauges.

13 34 19 2. Thermal Performance of Metal Roof Panel Assemblies at the Pre-Engineered Metal Building (Part C): Subpart 1.2.4.1 Metal Roof Panel Assemblies within Subpart 1.2.4 Thermal Performance of Specification Section 13 34 19 Metal Building Systems states, “U-factor: 0.02” and “R-value: 51.” However, the drawings indicate the ERA-2 Roof Assembly to be

The Contractor is not required to install a panelized metal roof system. Install ERA-2 roof assembly as indicated on Sheet A-002. The thermal performance criteria for ERA-2 is R=48 (min.) at roof drains. See enclosed amendment for revisions to Section 13 34 19.

installed on the roof of the pre-engineered metal building (Part C); not metal roof panel assemblies.

Please confirm our interpretation that the Contractor is not required to install metal roof panel assemblies with a U-Factor of 0.02 and

13 34 19 3. Air Infiltration of Metal Roof Panels at the Pre- Engineered Metal Building (Part C): Subpart 1.2.5 Air Infiltration for Metal Roof Panels of Specification Section 13 34 19 Metal Building Systems includes specific requirements for allowable air leakage through the roof assembly; however, the drawings do not require installation of any metal roof panel assemblies on the pre-engineered metal building (Part C).

Please confirm our interpretation that Subpart 1.2.5 of Specification Section 13 34 19 is not applicable.

Agree. Section 13 34 19, Sub-paragraph 1.2.5 Air Infiltration for Metal Roof Panels is not applicable as the roof system (ERA-2) is a composite field assembled roof system.

The Building Part C does require meeting an overall air barrier system leakage requirement.

See Section 07 27 10.00 10 Building Air Barrier System, Paragraph 1.6 for air barrier envelope reqiurements for Building Part C. See enclosed amendment deleting Pargraph 1.2.5 of Section 13 34 19.

13 34 19 4. Eave Height of the Pre-Engineered Metal Building (Part C): Subpart 1.3e Definitions of Specification Section 13 34 19 Metal Building Systems defines “Eave Height” as “Vertical dimension from finished floor to eave (the line along the sidewall formed by intersection of the planes of the roof and wall)” and Subpart 1.4.4 Eave Height states “Eave height must be 33 Ft., as indicated by nominal height on Drawings.”

However, the eave height of the pre-engineered metal building (Part C) indicated within the drawings is much greater than 33 feet. Please confirm the height that the eave height must be.

Refer to Section E1 / A-952 PEMB- Building Framing Drawings. The clear span eave height is established by the roof low point of the top chord of the rigid frame at Gird line 10.1; LP 200’- 8”. The Building Area ‘C’ finish floor is 165’-6” (01-FIRST FLR). The overall eave height from finish floor is 35’ – 2”, not inclusive of structural bearing. Minimum clearances shown on A-952 are to be maintained. See enclosed amendment for revision to Section 13 34 19, Para. 1.4.4.

25 05 11.03 5. Section 25 05 11.03 of the specifications is titled “Cybersecurity for Facility- Related Control Systems – Electric Gate Controllers.” However, Subpart 1.2 Control System Applicability within this section of the specifications states, “This specific Section applies only to the following control systems: Bacnet Direct Digital Control.” Please confirm our interpretation that there are not any sections of the specifications that provide requirements relating to cybersecurity for facility related control system associated with the electric gate controllers.

Cybersecurity requirements do apply to the Electric Gate Controllers. Section 11 12 00, Section 23 09 00, and Section 28 10 05 are revised as part of the enclosed amendment to clarify how the electric gate controllers are tied to the building management system, electronic security system, and fire alarm system and therefore require appropriate cybersecurity controls.

26 08 00 6. Apparatus Inspection and Testing for Underground Electrical Distribution: Subpart 1.3 Related Requirements of Section 33 71 02 Underground Electrical Distribution of the specifications states, “Section 26 08 00 Apparatus Inspection and Testing applies to this section . . .” However, Section 33 71 02 is not included as one of the specification sections listed within Subpart 3.1 Acceptance Tests and Inspections of Section 26 08 00 required to be performed by a first tier qualified testing organization / subcontractor.

Section 26 08 00 Apparatus Inspection and Testing is applicable to the testing and inspection requirements set forth within Section 33 71 02 Underground Electrical Distribution.

Paragraph 3.1 of Section 26 08 00 Apparatus Inspection and Testing is revised as part of the enclosed amendment. Additionally, revisions to Section 26 28 21.00 40, Section 26 32 14, and Section 26 51 00 to add testing

Please clarify whether or not Section 26 08 00 Apparatus Inspection and Testing is applicable to the testing and inspection requirements set forth within Section 33 71 02 Underground Electrical Distribution.

requirements are included in the enclosed amendment.

A-504 & A-533 7. Details A6/A-504 & E/A-533 indicate 1’-5” thick insulated panels. All other details indicate 1’-4” thick insulated panels. If 1’-5” thick panels are required, please provide a detailed explanation of the floors and gridlines that they occur at.

The 1’-5” dimension shown at the left panel in Detail A6/Sheet A- 504 is incorrect. The dimension of panel type “EWA-1” is 1’-4” as shown correctly to the right side of this same detail. The 1’-5” dimension shown at the panels in Detail E1/Sheet A-533 is incorrect, the correct dimension is 1’-4” as shown for the panel type “EWA-1” on Sheet A-002 for Exterior Wall Assembly “EWA-1”. See revised Sheets A-504 and A-533 in enclosed amendment.

8. Details indicate using splice sleeves at 12” oc for panel to panel and panel to foundation. Can we use welded connections in lieu of splice sleeves?

No, bid as shown.

A-511 9. Please verify that continuous non shrinking grout is only at the panel to foundation (A9/A-511).

Non-shrink grout shall be provided at panel to foundation connection. Further locations may be required for continual bearing as required by precast panel manufacturer.

A-710 10. Please provide description of Coreslab precast reference samples CS 1619 & CS 1613. We need the cement color and pigment color.

See revised Sheet A-710 included in enclosed amendment for colors requested.

Important Note: Though some drawings mention brand names, bidders may use any brand consistent with the requirements established in the Specifications.

A-609 11. Please verify that the 8” thick non-insulated panels PC-X (PC-4) are nonpigmented standard gray cement.

If not gray, please provide cement and pigment colors.

PC-X type panels are structural wythe back-up only panels, and should match other structural Wythe back-up portion of adjacent insulated panels. Standard grey cement is acceptable.

S-402 12. Detail C6A/S-402 indicates only 1” space between the steel structure and the back of precast panels. This space is inadequate due to tolerances of steel and precast. 2” space minimum is required. Please verify this space will be revised.

Agree that a 2" space is required. The change from a 1” to 2” spacing shall be accomplished by moving the perimeter column grids in by 1" so that the gap is increased to 2". See revised Structural and Architectural sheets included in enclosed amendment reflecting this change. Note that Sheet A-951, which is also affected by this request for information (RFI) is not included in the enclosed amendment as it is being further revised in response to other RFIs but will be reissued as part of a future amendment

The scope of the intumescent coating of structural members is shown on Drawings A-021 – A-024 in accordance with the Legend provided.

28. Stair C1.5 finishes are undefined. See revised Sheets A-611, A-701, and A-701C included as part of enclosed amendment providing the requested finishes for Stair C.

09 29 00 29. GWB Specification mentions abuse board, please indicate extent of locations or remove from specification.

Refer to the Interior Partition Types, Drawing A-003, Partition General Note #5 states “HIGH-

IMPACT GYPSUM BOARD TO BE

USED IN ALL LAB AREAS”. This material is specified in paragraph

2.1.5.3 Abuse Resistant Gypsum Board

– Impact Damage Duty Abuse Resistant, of Section 09 29 00 GYPSUM WALLBOARD . Partition General Note #12 on Sheet A-003 states:

“ABUSE-RESISTANT GYPSUM

BOARD TO BE USED AS THE

EXPOSED LAYER IN ALL

CORRIDORS, STAIRS, LOBBY,

AND RECEPTION AREAS.”

This material is specified in paragraph

2.1.5 Abuse Resistant Gypsum Board –

Surface Damage Duty of Section 09 29 00.

09 29 00 30. GWB specification calls for level 5 UNO, is this desired at all exposed GWB locations?

No, see revisions to Section 09 29 00 as part of the enclosed amendment. Level 5 finish is not required for this project

14 21 23 31. Elevator specification calls for 5,500 lb rated load for elevator #1. This is not a standard, should specification be changed to 3,500 lb?

No, minimum 5,500 lb rated elevator is a project requirement.

32. Section 08 11 00 outlines the “Blast Requirement” criteria and the glass is clearly defined on A-607. This is fine. With regard to thermal performance the center of the glass U Value is called out to be .25 and the metal panel requirements are .29. Typically to get to those values triple glazing and extra heavy thermal breaks would be required to get close however we are unaware of any manufacturers that can achieve both the blast ratings as well as the specified thermal characteristics. If unable to meet both criteria, is the blast rating more critical than the thermal requirements?

Seethe revisions to Section 08 81 00 GLAZING as part of the enclosed amendment. The revisions to the glazing in Section 08 81 00 are consistent with the Basis of Design indicated on Sheet A-710 and the configuration of the the laminated insulating glazing shown on Sheet A- 607.

08 71 00 A-605, A-606 33. Questions regarding doors, frames and hardware:

a. From the door schedule, comment “D” lists doors to be mineral core. None of the doors with this note are to be fire rated. Please verify if doors can be structural composite lumber per spec similar to other non-rated doors.

b. Door schedule comments D, E, and H mention sound seal gaskets and door bottom. Is it the intent that these doors require STC rating? No STC ratings are listed for these openings in the door schedule for these openings.

c. Electric locks are specified as Schlage L9000 series mortise locks. All other locks aren’t specified other than an ANSI number. Are there any specifics for the non-Schlage L9000 locks?

d. Schlage L9000 locks cannot be Marine Grade 1 per spec. If Marine Grade 1 is a requirement, please verify make and model of locks to meet Marine grade 1 non-ferrous and where Marine grade locks are to be used.

e. Some of the wood doors are calling for STC 60 ratings. We are not aware of a wood door manufacturer being able to make a STC 60 rated door. Can these be hollow metal?

a) No, this is a project requirement to provide better acoustic performance for the door. Provide doors in accordance requirements indicated on the drawings.

b) STC ratings are only called out for the Sound Control Door Assemblies as specified under Section 08 34 73. Other doors that have features attributed to acoustic treatments as noted by comments D, E, and H are intended for those doors as acoustic improvements over standard doors but with no STC requirement.

c)Subpart 2.3.6.2 of Section 08 71 00 states that electrified mortise locks shall be in accordance with ANSI/BHMA A156.25. All other hardware items shall be provided in accordance with ANSI/BHMA standards as stipulated in their respective specification paragraphs.

Important Note: Though some drawings mention brand names, bidders may use any brand consistent with the requirements established in the Specifications.

d) See revisions to Section 08 71 00 as part of enclosed amendment. Marine Grade I Locksets are not required for this project.

e) These STC rated doors are Sound Control Door Assemblies as noted by Comment B and are specified under Section 08 34 73. These are steel doors cladded with wood veneer as described in the specifications.

There are no Video Intercoms and no Key Pads in this project. GNERAL ACCESS CONTROL NOTE 2 on Sheet EV601 has been modified as part of the enclosed amendment to eliminate the references to Video Intercom and Key Pads

28 10 05 40. In Div 28 paragraph 2.2.1 it states 25% should be included. Is that based on including the Future count?

No, the 25% spare capacity is in addition to bid options. This requirement is for 25% spare capacity on the scope that is awarded. The base electronic security system should have 25% spare capacity if only the base scope is awarded. If Bid Option #009 is awarded, 25% space capacity should be provided on top of the base plus bid option scope.

M-502 41. Detail A1, A4, 7 A7 on drawing M-502 call for internal duct liner from the main supply duct to the last take off not less than 10 feet. Where the duct from the VAV or FPB is round, is the intention for the round duct to be internally lined resulting in a double wall duct? Is the internal duct liner required for all VAV’s & FPB’s or just where specifically indicated on the drawings?

The internal duct liner should be provided after each FPB/VAV terminal according to Details A1, A4, and A7 on Sheet M-502 to the last take off and at least 10’-0” long if the last take off is closer, and also as shown on the drawings, including supply, transfer and return ducts. If there is a single duct after the FPB/VAV terminal, then the duct liner should be provided not shorter than 10’-0” long and as shown on the drawings. The lining is not required in the Inventory, Laundry, Locker, Shower and Restrooms. All duct liner locations are specifically indicated on the drawings. The round duct lining is the same as rectangular duct lining – no double wall required.
